Date Developed: Shielded Metal Arc Welding NC II Developed by: JMCFI Document No. Page 1 of 48 pages INFORMATION SHEET 1.1.1-1 “Hazardous areas and Conditions” Learning Objectives: After reading the INFORMATION SHEET, YOU MUST be able to know and identify those hazardous areas and conditions. Five Potential Welding Safety Hazards to Avoid Safety is a critical consideration for any welding project. Arc welding is a safe occupation when proper precautions are taken. But, if safety measures are ignored, welders face an array of hazards which can be potentially dangerous, including electric shock, fumes and gases, fire and explosions and more. Welders face an array of hazards:electric shock, fumes and gases, fire. etc. To help keep welders safe, organizations such as the American Conference of Governmental Industrial Hygienists (ACGIH) and the Occupational Safety and Health Administration (OSHA) offer safety guidelines to help control, minimize or to help employers and workers avoid welding hazards. Employers should ensure all workers have an opportunity to comply with the following important guidelines in the workplace: 1. Read and understand manufacturer instructions for equipment carefully 2. Review material safety data sheets 3. Follow the company’s internal safety practices 1. Electric shock Electric shock is one of the most serious and immediate risks facing a welder. Electric shock can lead to severe injury or death, either from Date Developed: Shielded Metal Arc Welding NC II Developed by: JMCFI Document No. Page 1 of 48 pages the shock itself or from a fall caused by the reaction to a shock. Electric shock occurs when welders touch two metal objects that have a voltage between them, thereby inserting themselves into the electrical circuit. For instance, if a worker holds a bare wire in one hand and a second bare wire with another, electric current will pass through that wire and through the welding operator, causing an electric shock. The higher the voltage, the higher the current and, thus the higher the risk for the electric shock to result in injury or death. The most common type of electric shock is secondary voltage shock from an arc welding circuit, which ranges from 20 to 100 volts. To avoid secondary voltage shock, welding operators should wear dry gloves in good condition, never touch the electrode or metal parts of the electrode holder with skin or wet clothing and be sure to insulate themselves from the work and ground, keeping dry insulation between their body and the metal being welded or ground (such as a metal floor or wet surface). Welding operators also should inspect the electrode holder for damage before beginning to weld and keep the welding cable and electrode holder insulation in good condition, because the plastic or fiber insulation on the electrode holder prevents contact with the electrically “hot” metal parts inside. Always be sure to repair or replace damaged insulation before use. And remember, stick electrodes are always electrically hot, even when welding is not being done and the voltage is the highest. When not in use, but still turned on, most welding equipment have a voltage that ranges from 20 to 100 volts at the welding circuit and voltages inside the welding equipment may range from 120 volts to more than 575 volts, all of which pose a risk for electric shock. Only qualified repair technicians should attempt to service or repair welding equipment. 2. Fumes and gases It’s no surprise that overexposure to welding fumes and gases can be hazardous to your health. Welding fume contains potentially harmful complex metal oxide compounds from consumables, base metal and the basemetal coatings, so it’s important to keep your head out of the fumes and use enough ventilation and/or exhaust to control your exposure to substances in the fume, depending on the type of rod and base metal being used. Welding areas require adequate ventilation and local exhaust to keep fumes and gases from the breathing zone and the general area. 4. Fire and explosions. The welding arc creates extreme temperatures and may pose a significant fire and explosions hazard if safe practices are not followed. This spatter can reach up to 35 feet away from the welding space. To prevent fires, before beginning to weld, inspect the work area for any flammable materials and remove them from the area. Flammable materials are comprised of three categories: liquid, such as gasoline, oil and paint; solid, such as wood, cardboard and paper; gas, including acetylene, propane and hydrogen. 4. Injuries from insufficient PPE. Date Developed: Shielded Metal Arc Welding NC II Developed by: JMCFI Document No. Page 1 of 48 pages Personal protective equipment (PPE) helps keep welding operators free from injury, such as burns – the most common welding injury – and exposure to arc rays. The right PPE allows for freedom of movement while still providing adequate protection from welding hazards. Thanks to their durability and fire resistance, leather and flame-resistant treated cotton clothing is recommended in welding environments. This is because synthetic material such as polyester or rayon will melt when exposed to extreme heat. Welding leathers are especially recommended when welding out of position, such as applications that require vertical or overhead welding. PPE helps keep welding operators free from injury, such as burns – the most common welding injury and exposure to arc rays. 5. Other safety considerations. Welders should also be aware of other safety considerations within the work environment. For example, those working in a confined space or in an elevated area make need to take extra precautions. In any welding situation, welding operators should pay close attention safety information on the products being used and the material safety data sheets provided by the manufacturer and work with their employer and co-workers to follow appropriate safe practices for their workplace.

Blindness INFORMATION SHEET 1.1.1-2 “Signs and Symbols” Danger signs indicate an immediate hazard which, if not avoided, will result in death or serious injury. Danger signs should be limited to the most extreme situations and signify that special precautions are necessary. The heading “DANGER” is printed in white letters on a red background and is preceded by the safety alert symbol (an equilateral triangle surrounding an exclamation mark). The message should be printed in black or red letters on a white background, or white letters on a black background. Additional safety symbols may be included in the message area. Warning signs represent a hazard level between caution and danger. “Warning” indicates a hazardous situation which, if not avoided, could result in death or serious injury. The heading “WARNING” (preceded by the safety alert symbol) is written in black on an orange background. Additional wording and safety symbols are printed in black on the lower portion of the sign. Warning signs and labels can be any size, but it is appropriate for the sign to be noticed and easily read from a safe distance. They need to communicate the warning information before someone is in a dangerous area or acts in a dangerous manner. Caution sign indicates a potentially hazardous situation which, if not avoided, may result in minor or moderate injury. Caution signs are used in areas where potential injury or equipment damage is possible, or to caution against unsafe practices. Caution signs should only be used if there is a risk of personal injury. The heading “CAUTION” is written in black letters on a yellow background and is preceded by the safety alert symbol. The message and safety symbols in the body of the sign are printed in black. Notice signs provide general information that is important or relevant to a building, an area, a machine, or equipment. Notice signs address practices not related to personal injury. General Safety signs are used to provide notices of general practice and rules relating to health, first aid, medical equipment, sanitation, Date Developed: Shielded Metal Arc Welding NC II Developed by: JMCFI Document No. Page 1 of 48 pages housekeeping, and suggestions relative to general safety measures. The message and safety symbols should be printed in green or black on a white background. The signs may also be printed in white on a green background. These signs should never include the safety alert symbol. Fire Safety signs are used to indicate the location of emergency firefighting equipment. Unlike other signs, they do not require a header. The message and safety symbol are printed in red on a white background, or in white on a red background. Because these signs do not indicate a personal safety hazard, the safety alert symbol must not be used. Fire safety signs are not used to show the direction to fire equipment, but rather its immediate location Admittance signs bridges all of the above categories. Admittance messages may be included on a sign with any header. You might decide to put “Unauthorized Personnel, Keep Out” on a danger, warning, caution, or notice sign. Safety Symbols - Signs and labels may include safety symbols, often called pictograms pictorials, or glyphs. Safety symbols can portray required actions, consequences, explicit direction, or the effects of interaction with certain chemicals, machines, and other hazards. Signs and labels may include more than one pictorial to show a sequence of events for one hazard. Safety symbols should be consistent, readable, and easily understood. They usually consist of a black image on a white background. Safety Symbols 1. Electrical Safety Symbol also called the high voltage sign; this sign usually has an electric wire with the plug attached to it or a zigzag arrow as shown here. It is used to tell people there may be certain electrical machines and/or equipment in the vicinity. Which is why, keeping utmost care is necessary as there can be danger of getting an electric shock. 2. Eye Safety symbol - the sign shows a pair of snow goggles. This suggests that there may be hazardous materials which can cause irritation to the eyes. Hence, wearing protective eye goggles is necessary in that vicinity. It is necessary because there can be substances that can damage or cause injury to your eyes. You always have to wear the suggested eye goggles required in the area . 3. First Aid Symbol a square box with a green + sign, usually indicates medical emergency. This is an internationally accepted symbolAt times, the Red Cross symbol is also used, but it is to let people know that there is an ambulance service in the nearby vicinity. 4. Flammable Symbol a sign of fire which usually means that in that particular vicinity, it is possible to catch fire fairly easily. This sign can be indicated through various symbols. Although, a yellow or white background with flames is typically shown to indicate the possible danger. The substance/chemical in that area is the reason for the risk of fire. 5. Harmful/Irritant Symbol Harmful symbol is denoted by an X with a small 'h' Date Developed: Shielded Metal Arc Welding NC II Developed by: PTC-SAMAR Document No. Page 10 of 48 pages on the bottom-right corner and the irritant symbol is denoted by an X with a small 'i' on the bottom-right corner. This harmful substance or material can cause irritation to your eyes, skin, or anywhere inside the body. 6. Poison Symbol Somewhat similar to the danger symbol, the poison symbol also has a skull with two bones. This symbol usually means that there may be poisonous materials in the vicinity and extra care and precautions are to be taken. Wearing proper clothes, as mentioned or advised, should always be on . 7. Radio Active Symbol This is another well-known symbol. This sign usually tells that there may be radioactive substances or materials in the area. Due to exposure to radiation, a person may suffer damage to their cells, and it may cause cancer as well. Extreme care is to be taken while in the area; actually, only authorized personnel are allowed in this area. SELF CHECK LO1.1.1-1 Test I.

Type of available PPE when welding. The chart below summarizes the types of personal protective equipment that can be used when welding. Welding - Personal Protective Equipment Body Part Equipment Illustration Reason Date Developed: Shielded Metal Arc Welding NC II Developed by: JMCFI Document No. Page 18 of 48 pages Eyes face and Welding helmet, hand shield, or goggles Protects from: Lungs breathing Respirators Protects against: Exposed skin (other than feet, hands, and head) Ears hearing Fire/Flame resistant clothing and aprons radiation hot slag, sparks intense light irritation and chemical burns. Wear fire resistant head coverings under the helmet where appropriate fumes and oxides Protects against: heat, fires burns Notes: pants should not have cuffs; shirts should have flaps over pockets or be taped closed. - Earmuffs, ear plugs Protects against: noise Use fire resistant ear plugs where sparks or splatter may enter the ear. Feet and Boots, hands gloves Protects against: electric shock heat burns fires Personal Protective Equipment (PPE) refers to protective clothing, helmets, goggles, or other garments or equipment designed to protect the wearer's body from injury or infection. The hazards addressed by protective equipment include physical, electrical, heat, chemicals, biohazards, and airborne particulate matter. Protective equipment may be worn for job-related health purposes, as well as Date Developed: Shielded Metal Arc Welding NC II Developed by: JMCFI Document No. Page 18 of 48 pages for sports and other recreational activities. "Protective clothing" is applied to traditional categories of clothing, and "protective gear" applies to items such as pads, guards, shields, or masks, and others. What the purpose of PPE? The purpose of personal protective equipment is to reduce the worker of exposure to hazards when engineering and administrative controls are not feasible or effective to reduce these risks to acceptable levels. PPE is needed when there are hazards present. PPE has the serious limitation that it does not eliminate the hazard at source and may result in employees being exposed to the hazard if the equipment fails. Personal protective equipment (PPE) can be categorized by the area of the body protected, by the types of hazard, and by the type of garment or accessory. What are the problems with using the PERSONAL PROTECTIVE EQUIPMENT? Where personal protective equipment (PPE) is provided and used at work, you should remember that: wearing PPE may adversely affect the performance of tasks being undertaken (e.g. restricting vision or mobility) PPE may be uncomfortable to wear, and some workers may not be able to wear it (e.g. workers who are allergic to latex cannot wear rubber gloves) ongoing supervision is required to ensure the PPE is being used correctly, and PPE may create new hazards (for example some items of PPE can hinder the body’s natural cooling mechanisms by preventing evaporation of perspiration). What standard of PERSONAL PROTECTIVE EQUIPMENT is required? The standard of personal protective equipment used at a workplace must be: selected to minimize risk to health and safety suitable for the nature of the work and any hazard associated with the work a suitable size and fit and reasonably comfortable for the person wearing it maintained, repaired or replaced so it continues to minimize the worker’s health and safety risk, and Used or worn by the worker, so far as is reasonably practicable. The Requirement for PPE To ensure the greatest possible protection for employees in the workplace, the cooperative efforts of both employers and employees will help in establishing and maintaining a safe and healthful work environment. In general, employers are responsible for: Performing a "hazard assessment" of the workplace to identify and control physical and health hazards. Identifying and providing appropriate PPE for employees. Training employees in the use and care of the PPE. Maintaining PPE, including replacing worn or damaged PPE. Periodically reviewing, updating and evaluating the effectiveness of the PPE program. In general, employees should: Properly wear PPE, Attend training sessions on PPE, Date Developed: Shielded Metal Arc Welding NC II Developed by: JMCFI Document No. Page 18 of 48 pages Care for, clean and maintain PPE, and Inform a supervisor of the need to repair or replace PPE. The Hazard Assessment The hazard assessment should begin with a walk-through survey of the facility to develop a list of potential hazards in the following basic hazard categories: Impact, Penetration, Compression (roll-over), Chemical, Heat/cold, Harmful dust, Light (optical) radiation, and Biologic. In addition to noting the basic layout of the facility and reviewing any history of occupational illnesses or injuries, things to look for during the walk-through survey include: Sources of electricity. Sources of motion such as machines or processes where movement may exist that could result in an impact between personnel and equipment. Sources of high temperatures that could result in burns, eye injuries or fire. Types of chemicals used in the workplace. Sources of harmful dusts. Sources of light radiation, such as welding, brazing, cutting, furnaces, heat treating, high intensity lights, etc. The potential for falling or dropping objects. Sharp objects that could poke, cut, stab or puncture. Biologic hazards such as blood or other potentially infected material. 1. Eye and Face Protection Employees can be exposed to many hazards that pose danger to their eyes and face. OSHA requires employers to ensure that employees have appropriate eye or face protection if they are exposed to eye or face hazards from flying particles, molten metal, liquid chemicals, acids or caustic liquids, chemical gases or vapors, potentially infected material or potentially harmful light radiation. Types of Eye Protection. Selecting the most suitable eye and face protection for employees should take into consideration the following elements: Date Developed: Shielded Metal Arc Welding NC II Developed by: JMCFI Document No. Page 18 of 48 pages Ability to protect against specific workplace hazards. Should fit properly and be reasonably comfortable to wear. Should provide unrestricted vision and movement. Should be durable and cleanable. Should allow unrestricted functioning of any other required PPE. Common types of eye and face protection 1. Safety Goggles These are tight-fitting eye protection that completely cover the eyes, eye sockets and the facial area immediately surrounding the eyes and provide protection from impact, dust and splashes. Some goggles will fit over corrective lenses. 2. Safety Glasses These protective eyeglasses have safety frames constructed of metal or plastic and impact-resistant lenses. Side shields are available on some models. 3. Welding mask/Welding shield Head Protection Protecting potential head element of any head injury can for life or it can safety helmet or the easiest ways employee's head hats can protect impact and as well as from burn hazards. employees from injuries is a key safety program. A impair an employee be fatal. Wearing a hard hat is one of to protect an from injury. Hard employees from penetration hazards electrical shock and Employers must ensure that their employees wear head protection if any of the following apply: Objects might fall from above and strike them on the head; They might bump their heads against fixed objects, such as exposed pipes or beams; or There is a possibility of accidental head contact with electrical hazards. Types of Hard Hats Date Developed: Shielded Metal Arc Welding NC II Developed by: JMCFI Document No. Page 18 of 48 pages There are many types of hard hats available in the marketplace today. In addition to selecting protective headgear that meets ANSI standard requirements, employers should ensure that employees wear hard hats that provide appropriate protection against potential workplace hazards. It is important for employers to understand all potential hazards when making this selection, including electrical hazards. Hard hats are divided into three industrial classes: Class A hard hats provide impact and penetration resistance along with limited voltage protection (up to 2,200 volts). Class B hard hats provide the highest level of protection against electrical hazards, with high-voltage shock and burn protection (up to 20,000 volts). They also provide protection from impact and penetration hazards by flying/falling objects. Class C hard hats provide lightweight comfort and impact protection but offer no protection from electrical hazards. Hard hats with any of the following defects should be removed from service and replaced: Perforation, cracking, or deformity of the brim or shell; Indication of exposure of the brim or shell to heat, chemicals or ultraviolet light and other radiation (in addition to a loss of surface gloss, such signs include chalking or flaking). Always replace a hard hat if it sustains an impact, even if damage is not noticeable. 2. Foot and Leg Protection - Employees who face possible foot or leg injuries from falling or rolling objects or from crushing or penetrating materials should wear protective footwear. Also, employees whose work involves exposure to hot substances, or corrosive or poisonous materials must have protective gear to cover exposed body parts, including legs and feet. If an employee's feet may be exposed to electrical hazards, non-conductive footwear should be worn. On the other hand, workplace exposure to static electricity may necessitate the use of conductive footwear. Foot and leg protection choices include the following: Date Developed: Shielded Metal Arc Welding NC II Developed by: JMCFI Document No. Page 18 of 48 pages Leggings protect the lower legs and feet from heat hazards such as molten metal or welding sparks. Safety snaps allow leggings to be removed quickly. Metatarsal guards protect the instep area from impact and compression. Made of aluminum, steel, fiber or plastic, these guards may be strapped to the outside of shoes. Toe guards fit over the toes of regular shoes to protect the toes from impact and compression hazards. They may be made of steel, aluminum or plastic. Combination foot and shin guards protect the lower legs and feet and may be used in combination with toe guards when greater protection is needed. Safety shoes have impact-resistant toes and heat-resistant soles that protect the feet against hot work surfaces common in roofing, paving and hot metal industries. The metal insoles of some safety shoes protect against puncture wounds. Safety shoes may also be designed to be electrically conductive to prevent the buildup of static electricity in areas with the potential for explosive atmospheres or nonconductive to protect workers from workplace electrical hazards. SPECIAL PURPOSE OF SHOES: Electrically conductive shoes provide protection against the buildup of static electricity. Employees working in explosive and hazardous locations such as explosives manufacturing facilities or grain elevators must wear conductive shoes to reduce the risk of static electricity buildup on the body that could produce a spark and cause an explosion or fire. Electrical hazard, safety-toe shoes are nonconductive and will prevent the wearers' feet from completing an electrical circuit to the ground. These shoes can protect against open circuits of up to 600 volts in dry conditions and should be used in conjunction with other insulating equipment and additional precautions to reduce the risk of a worker becoming a path for hazardous electrical energy. 3. Hand and Arm Protection - If a workplace hazard assessment reveals that employees face potential injury to hands and arms that cannot be eliminated through engineering and work practice controls, employers must ensure that employees wear appropriate protection. Potential hazards include skin absorption of harmful substances, chemical or thermal burns, electrical dangers, bruises, abrasions, cuts, punctures, fractures and amputations. Protective equipment includes gloves, finger guards and arm coverings or elbow-length gloves. Date Developed: Shielded Metal Arc Welding NC II Developed by: JMCFI Document No. Page 18 of 48 pages Types of gloves Sturdy gloves made from metal mesh, leather or canvas provide protection against cuts and burns. Leather or canvass gloves also protect against sustained heat. Leather gloves protect against sparks, moderate heat, blows, chips and rough objects. Aluminized gloves provide reflective and insulating protection against heat and require an insert made of synthetic materials to protect against heat and cold. Aramid fiber gloves protect against heat and cold, are cut - and abrasive - resistant and wear well. Synthetic gloves of various materials offer protection against heat and cold, are cut - and abrasive - resistant and may withstand some diluted acids. These materials do not stand up against alkalis and solvents. Fabric gloves protect against dirt, slivers, chafing and abrasions. They do not provide sufficient protection for use with rough, sharp or heavy materials. Adding a plastic coating will strengthen some fabric gloves. Coated fabric gloves are normally made from cotton flannel with napping on one side. By coating the unnapped side with plastic, fabric gloves are transformed into general-purpose hand protection offering slip-resistant qualities. 4. BODY PROTECTION COVER ALL-which protect your body from hazardous environments Employees who face possible bodily injury of any kind that cannot be eliminated through engineering, work practice or administrative controls, must wear appropriate body protection while performing their jobs. 5. Hearing Protection Determining the need to provide hearing protection for employees can be challenging. Employee exposure to excessive noise depends upon several factors, including: The loudness of the noise as measured in decibels (dB). The duration of each employee's exposure to the noise. Whether employees move between work areas with different noise levels. Whether noise is generated from one or multiple sources. Date Developed: Shielded Metal Arc Welding NC II Developed by: JMCFI Document No. Page 18 of 48 pages Types of Hearing protection Single-use earplugs are made of waxed cotton, foam, silicone rubber or fiberglass wool. They are self-forming and, when properly inserted, they work as well as most molded earplugs. Pre-formed or molded earplugs must be individually fitted by a professional and can be disposable or reusable. Reusable plugs should be cleaned after each use. Earmuffs require a perfect seal around the ear. Glasses, facial hair, long hair or facial movements such as chewing may reduce the protective value of earmuffs. Earmuffs are objects designed to cover a person's ears for protection or for warmth. They consist of a thermoplastic or balneal head band which fits over the top or back of the head, and a pad at each end, to cover the external ears. What are some tips to know when using protective clothing? DO: Wear clothing made from heavyweight, tightly woven, 100% wool or cotton to protect from UV radiation, hot metal, sparks and open flames. Flame retardant treatments become less effective with repeated laundering. Keep clothing clean and free of oils, greases and combustible contaminants. Wear long-sleeved shirts with buttoned cuffs and a collar to protect the neck. Dark colors Prevent light reflection. Tape shirt pockets closed to avoid collecting sparks or hot metal or keep them covered with flaps. Pant legs must not have cuffs and must cover the tops of the boots. Cuffs can collect sparks. Repair all frayed edges, tears or holes in clothing. Wear high top boots fully laced to prevent sparks from entering into the boots. Use fire-resistant boot protectors or spats strapped around the pant legs and boot tops, to prevent sparks from bouncing in the top of the boots. Remove all ignition sources such as matches and butane lighters from pockets. Hot welding sparks may light the matches or ignite leaking lighter fuel. Wear gauntlet-type cuff leather gloves or protective sleeves of similar material, to protect wrists and forearms. Leather is a good electrical insulator if kept dry. Direct any spark spray away from your clothing. Wear leather aprons to protect your chest and lap from sparks when standing or sitting. Wear layers of clothing. To prevent sweating, avoid overdressing in cold weather. Sweaty clothes cause rapid heat loss. Leather welding jackets are not very breathable and can make you sweat if you are overdressed. Date Developed: Shielded Metal Arc Welding NC II Developed by: JMCFI Document No. Page 18 of 48 pages Wear a fire-resistant skull cap or balaclava hood under your helmet to protect your head from burns and UV radiation. Wear a welder's face shield to protect your face from UV radiation and flying particles. DO NOT Do not wear rings or other jewelry. Do not wear clothing made from synthetic or synthetic blends. The synthetic fabric can burn vigorously, melt and produce bad skin burns. SELF CHECK 1.2.1 Test I - Instructions: This is a multiple-choice type of test. Read carefully the questions below.

INFORMATTION SHEET 1.3.1 “Safe handling of Tools, Equipment and materials” Learning Objectives: After reading the INFORMATION SHEET, YOU MUST be able to know on how to perform safe handling of tools, equipment and materials. Power Tools A power tool- is a tool that is actuated by an additional power source and mechanism other than the solely manual labor used with hand tools. The most common types of power tools use electric motors. Power tools are used in industry, in construction, in the garden, for housework tasks such as cooking, cleaning, and around the house for purposes of driving (fasteners), drilling, cutting, shaping, sanding, grinding, routing, polishing, painting and heating. Power tools are classified as either stationary or portable, Where portable means hand-held. Portable power tools have obvious advantages in mobility. Stationary power tools however often have advantages in speed and accuracy, and some stationary power tools can produce objects that cannot be made in any other way. Stationary power tools for metalworking are usually called machine tools. The term machine tool is not usually applied to stationary power tools for woodworking, although such usage is occasionally heard, and in some cases, such as drill presses and bench grinders, exactly the same tool is used for both woodworking and metalworking. Energy sources. Currently an electric motor is the most popular choice to power stationary tools, though in the past they were powered by windmills, water wheels and steam. Safety While power tools are extremely helpful, they also produce large amounts of noise and vibrations. Using power tools without hearing protection over a long period of time can put a person at risk for hearing loss. The US National (NIOSH) has recommended that a person should not be exposed to noise at or above 85 dB, for the sake of hearing loss prevention. Most power tools, including drills, circular saws, belt sanders, and chainsaws, operate at sound levels above the 85 dB limit, some even reaching over 100 Date Developed: Shielded Metal Arc Welding NC II Developed by: JMCFI Document No. Page 31 of 48 pages dB. Noise strongly recommends wearing hearing protection while using these kinds of power tools. A drill press (also known as pedestal drill, pillar drill, or bench drill) is a fixed style of drill that may be mounted on a stand or bolted to the floor or workbench. Portable models with a magnetic base grip the steel workpieces they drill. A drill press consists of a base, column (or pillar), table, spindle (or quill), and drill head, usually driven by an induction motor. The head has a set of handles (usually 3) radiating from a central hub that, when turned, move the spindle and chuck vertically, parallel to the axis of the column. The table can be adjusted vertically and is generally moved by a rack and pinion; however, some older models rely on the operator to lift and re-clamp the table in position. A drill press has several advantages over a hand-held drill: Less effort is required to apply the drill to the workpiece. The movement of the chuck and spindle is by a lever working on a rack and pinion, which gives the operator considerable mechanical advantage The table allows a vise or clamp to be used to position and restrain the work, making the operation much more secure The angle of the spindle is fixed relative to the table, allowing holes to be drilled accurately and consistently. Drill presses are almost always equipped with more powerful motors compared to hand-held drills. This enables larger drill bits to be used and speeds up drilling with smaller bits. Bench grinding machine .Rotating abrasive wheel on a bench grinder. A grinding machine, often shortened to grinder, is a machine tool used for grinding, which is a type of machining using an abrasive wheel as the cutting tool. Each grain of abrasive on the wheel's surface cuts a small chip from the workpiece via shear deformation. Grinding is used to finish workpieces that must show high surface quality (e.g., low surface roughness) and high accuracy of shape and dimension. However, there are some roughing applications in which grinding removes high volumes of metal quite rapidly. Thus, grinding is a diverse field. Bench Grinding machines remove material from the workpiece by abrasion, which can generate substantial amounts of heat; they therefore incorporate a coolant to cool the workpiece so that it does not overheat and go outside its tolerance. The coolant also benefits the machinist as the heat generated may cause burns in some cases. A cylindrical grinder. These machines include the: Date Developed: Shielded Metal Arc Welding NC II Developed by: JMCFI Document No. Page 32 of 48 pages Belt grinder, which is usually used as a machining method to process metals and other materials, with the aid of coated abrasives. Sanding is the machining of wood; grinding is the common name for machining metals. Belt grinding is a versatile process suitable for all kind of applications like finishing, deburring, and stock removal. Bench grinder, which usually has two wheels of different grain sizes for roughing and finishing operations and is secured to a workbench or floor stand. Its uses include shaping tool bits or various tools that need to be made or repaired. Bench grinders are manually operated. Cylindrical grinder, which includes both the types that use centers and the centerless types. A cylindrical grinder may have multiple grinding wheels. The workpiece is rotated and fed past the wheel(s) to form a cylinder. It is used to make precision rods, tubes, bearing races, bushings, and many other parts. Surface grinder which includes the wash grinder. A surface grinder has a "head" which is lowered, and the workpiece is moved back and forth past the grinding wheel on a table that has a permanent magnet for use with magnetic stock. Tool and cutter grinder and the D-bit grinder. These usually can perform the minor function of the drill bit grinder, or other specialist toolroom grinding operations. Jig grinder, which as the name implies, has a variety of uses when finishing jigs, dies, and fixtures. Its primary function is in the realm of grinding holes and pins.

If not, read the information sheets again to answer all the questions correctly. INFORMATION SHEET 1.4.1 “FIRST AID PROCEDURE” Learning Objectives: After reading the INFORMATION SHEET, YOU MUST be able to know on how to perform first aid procedure. First AID. Basic first aid refers to the initial process of assessing and addressing the needs of someone who has been injured or is in physiological distress due to choking, a heart attack, allergic reactions, drugs or alcohol or other medical emergencies. Basic first aid allows you to quickly determine a person's physical condition and the correct course of treatment. You should always seek professional medical help as soon as you are able, but following correct first aid procedures can be the difference between life and death. Note: Much of this article deals with first aid for life threatening situations in which the victim is unresponsive. Many of these steps will not apply in situations where you already know the problem or the extent of the harm to a person. In that case, you should search for the specific article, or skim this one to find more information on addressing conditions. For brain injury, patients will have obvious improvement in 5 weeks. First AID Steps. 1. Evaluate the situation. Are there things that might put you at risk of harm? Are you or the victim threatened by fire, toxic smoke or gasses, an unstable building, live electrical wires or other dangerous scenario? Do not rush into a situation where you could end up as a victim yourself. If approaching the victim will endanger your life, seek professional help immediately; they have higher levels of training and know how to handle these situations. 2. Remember your A,B,Cs. The A,B,Cs of first aid refer to the three critical things you need to look for. Airway – Does the person have an unobstructed airway? Breathing – Is the person breathing? Circulation – Does the person show a pulse at major pulse points (wrist, carotid artery, and groin)? 3. Avoid moving the victim. Avoid moving the victim unless they are in immediate danger. Moving a victim will often make injuries worse, especially in the case of spinal cord injuries. 4. Call Emergency Services. Call for help or tell someone else (a specific person, if possible) to call for help as soon as possible. If you are the only person on the Date Developed: Shielded Metal Arc Welding NC II Developed by: JMCFI Document No. Page 38 of 48 pages scene, try to establish breathing before calling for help, and do not leave the victim alone for an extensive amount of time. 5. Determine responsiveness. If a person is unconscious, try to rouse them by gently shaking and speaking to them. 6. If the person remains unresponsive, carefully roll them onto their back and open his airway. Keep head and neck aligned. Carefully roll them onto their back while holding his head. Open the airway by lifting the chin. 7. Look, listen and feel for signs of breathing. Look for the victim's chest to rise and fall, listen for sounds of breathing (place your ear near the nose and mouth, and feel for breathe on your cheek. If the victim is not breathing, see the section below. If the victim is breathing, but unconscious, roll them onto their side, keeping the head and neck aligned with the body. This will help drain the mouth and prevent the tongue or vomit from blocking the airway. 8. Check the victim's circulation. Look at the victim's color and check their pulse (the carotid artery is a good option; it is located on either side of the neck, below the jawbone). If the victim does not have a pulse, start CPR.(Cardiopulmonary Resuscitation) 9. Treat bleeding, shock, and other problems as needed. After you have established that the victim is breathing and has a pulse, your next priority should be to control any bleeding. Particularly in the case of trauma, you should take steps to control or prevent shock. How to Stop Bleeding– Control of bleeding is one of the most important things you can do to save a trauma victim. Use direct pressure on a wound before trying any other method of managing bleeding. Read the linked article for more detailed steps you can take. How to Treat Shock– Shock, a loss of blood flow to the body, frequently follows physical and occasionally psychological trauma. A person in shock will frequently have cool, clammy skin, be agitated or have an altered mental status, and have pale color to the skin around the face and lips. Untreated, shock can be fatal. Anyone who has suffered a severe injury or life-threatening situation is at risk for shock. How to Help a Choking Victim – Choking can cause death or permanent brain damage within minutes. Read this article for ways to help a choking victim. The article addresses helping both children and adult choking victims. How to Treat a Burn– Treat first and second degree burns by immersing or flushing with cool water (no ice). Don't use creams, butter or other ointments, and do not pop blisters. Third degree burns should be covered with a damp cloth. Remove clothing and jewelry from the burn, but do not try to remove charred clothing that is stuck to burns. Treat a Concussion – If the victim has suffered a blow to the head, look for signs of concussion. Common symptoms are loss of consciousness following the injury, disorientation or memory impairment, vertigo, nausea, and lethargy. Read the linked article for the best ways to treat a concussion. Date Developed: Shielded Metal Arc Welding NC II Developed by: JMCFI Document No. Page 39 of 48 pages How to Treat a Spinal Injury Victim – If you suspect a spinal injury, it is especially critical that you not move the victim's head, neck or back UNLESS THEY ARE IN IMMEDIATE DANGER. You also need to take special care when performing rescue breathing or CPR. Read this article to learn what to do. How to Treat a Bullet Wound – Bullet wounds are serious and unpredictable. Read on for special considerations when treating someone who has suffered a gunshot wound. 10. Stay with the victim until help arrives. Try to be a calming presence for the victim until assistance can arrive. Burns - Home Treatment. Most minor burns will heal on their own, and home treatment is usually all that is needed to relieve your symptoms and promote healing. But if you suspect you may have a more severe injury, use first-aid measures while you arrange for an evaluation by your doctor. Immediate first aid for burns. First, stop the burning to prevent a more severe burn. Heat burns (thermal burns): Smother any flames by covering them with a blanket or water. If your clothing catches fire, do not run: stop, drop, and roll on the ground to smother the flames. ELECTRICAL BURN INJURY SELF CHECK 1.4.1 Direction: On your answer sheet provided, write the correct answer that correspond the question below. 1. How to Treat a Burn? 2. How to Treat Shock? 3.

INFORMATION SHEET 1.5.1 “Fire extinguisher” Learning Objectives: After reading the INFORMATION SHEET, YOU MUST be able to know about the importance of fire extinguishers. "Extinguisher" redirects here. Extinguisher may also refer to a candle snuffer. A stored-pressure fire extinguisher made by Amerex, A fire extinguisher, flame extinguisher, or simply an extinguisher, is an active fire protection device used to extinguish or control small fires, often in emergency situations. It is not intended for use on an out-of-control fire, such as one which has reached the ceiling, endangers the user (i.e., no escape route, smoke, explosion hazard, etc.), or otherwise requires the expertise of a fire department. Typically, a fire extinguisher consists of a hand-held cylindrical pressure vessel containing an agent which can be discharged to extinguish a fire. In the Philippines, fire extinguishers, in all buildings other than houses, are generally required to be serviced and inspected by a Fire Protection service company at least annually. Some jurisdictions require more frequent service for fire extinguishers. The servicer places a tag on the extinguisher to indicate the type of service performed (annual inspection, recharge, new fire extinguisher) There are two main types of fire extinguishers: Stored pressure -In stored pressure units, the expellant is stored in the same chamber as the firefighting agent itself. Depending on the agent used, different propellants are used. With dry chemical extinguishers, nitrogen is typically used; water and foam extinguishers typically use air. Stored pressure fire extinguishers are the most common type. Cartridge-operated - Cartridge-operated extinguishers contain the expellant gas in a separate cartridge that is punctured prior to discharge, exposing the propellant to the extinguishing agent. This type is not as common, used primarily in areas such as industrial facilities, where they receive higher-than-average use. Fire extinguishers are further divided into handheld and cart-mounted, also called wheeled extinguishers. Handheld extinguishers weigh from 0.5 to 14 kilograms (1 to 30 pounds), and are hence, easily portable by hand. Date Developed: Shielded Metal Arc Welding NC II Developed by: JMCFI Document No. Page 42 of 48 pages Cart-mounted units typically weigh 23+ kilograms (50+ pounds). These wheeled models are most commonly found at construction sites, airportrunways, heliports, as well as docks and marinas. History. The first fire extinguisher of which there is any record was patented in England in 1723 by Ambrose Godfrey, a celebrated chemist at that time and to this day. It consisted of a cask of fire-extinguishing liquid containing a pewter chamber of A glass "grenade" style extinguisher, to be thrown into a fire. Another type of carbon-tetrachloride extinguisher was the Fire grenade. This consisted of a glass sphere filled with CTC, that was intended to be hurled at the base of a fire (early ones used salt-water, but CTC was more effective). The chemical foam extinguisher was invented in 1904 by Aleksandr Loran Russia, based on his previous invention of fire fighting foam. in A chemical foam extinguisher with contents. The carbon dioxide (CO2) extinguisher was invented (at least in the US) by the Walter Kidde Company in 1924 in response to Bell Telephone's request for an electrically non-conductive chemical for extinguishing the previously-difficult-toextinguish fires in telephone switchboards. It consisted of a tall metal cylinder containing 7.5 lbs. of CO2 with a wheel valve and a woven brass, cotton covered hose, with a composite funnel-like horn as a nozzle An early dry chemical extinguisher, the first ones had copper cylinders, this one is steel. It consisted of a copper cylinder with an internal CO2cartridge. The operator turned a wheel valve on top to puncture the cartridge and squeezed a lever on the valve at the end of the hose to discharge the chemical. This was the first agent available for large scale threedimensional liquid and pressurized gas fires, and was but remained largely a specialty type until the 1950s, when small dry chemical units Date Developed: Shielded Metal Arc Welding NC II Developed by: JMCFI Document No. Page 43 of 48 pages were marketed for home use. ABC dry chemical came over from Europe in the 1950s, with Super-K being invented in the early 60s and Purple-K being developed by the US Navy in the late 1960s.

Maintenance. Date Developed: Shielded Metal Arc Welding NC II Developed by: JMCFI Document No. Page 44 of 48 pages Most countries in the world require regular fire extinguisher maintenance by a competent person to operate safely and effectively, as part of fire safety legislation. Lack of maintenance can lead to an extinguisher not discharging when required or rupturing when pressurized. Deaths have occurred, even in recent times, from corroded extinguishers exploding. In the Philippines, three types of maintenance are required: Basic Service: All types of extinguisher require a basic inspection annually to check weight, correct pressure (using a special tool, not just looking at the gauge) and for signs of damage or corrosion, cartridge extinguishers are opened up for internal inspection & check weighing of the cartridge, labels are checked for legibility, where possible dip tubes, hoses and mechanisms checked for clear free operation. Extended Service: Water, Wet Chemical, Foam & Powder extinguishers require every five years a more detailed examination including a test discharge of the extinguisher and recharging; on stored pressure extinguishers this is the only opportunity to internally inspect for damage/corrosion. Overhaul: CO2 extinguishers, due to their high operating pressure, are subject to pressure vessel safety legislation and must be hydraulic pressure tested, inspected internally & externally and date stamped every 10 years. As it cannot be pressure tested a new valve is also fitted. If replacing any part of the extinguisher (valve, horn, etc.) with a part from another manufacturer then the extinguisher will lose its fire rating. This may invalidate insurance, as would incorrect or inadequate servicing if it were to be found. In the United States there are 3 types of service as well: Maintenance Inspection: All types of extinguishers should be inspected at least once a year. The extinguisher is checked to make sure it has proper pressure (gauge in green or proper cartridge weight), has the correct volume of extinguishing agent (tech weighs it), is within the required hydrotest and internal maintenance intervals, is in good condition and all external parts are serviceable. Often, dry chemical and dry powder types are hit on the bottom with a rubber mallet to make sure the powder is free flowing, which is called "fluffing" the powder. The tech will then attach a new tamper seal around the pin and a yearly service tag. The extinguisher is emptied of its chemical and pressure to check for proper operation. All components are disassembled, inspected, cleaned, lubricated, or replaced if defective. Date Developed: Shielded Metal Arc Welding NC II Developed by: JMCFI Document No. Page 45 of 48 pages Liquid agents are replaced at this time, dry agents may be re-used if in good condition, halon is recovered and re-used, but CO2 is discharged into the atmosphere. The extinguisher is then re-filled and recharged, after a "verification of service" collar is placed around the cylinder neck. It is impossible to properly install or remove a collar without depressurizing the extinguisher. Note: Cartridge-operated extinguishers should be visually examined, but do not require a verification of service collar. Hydrostatic testing: Water, Foam, Wet chemical, and CO 2, every 5 years. Dry chemical, dry powder, halon, and clean agents, every 12 years. Note: these are the required intervals for normal service conditions, if the extinguisher has been exposed to excessive heat, vibration, or mechanical damage it may need to be tested sooner.

INFORMATION SHEET 1.5.3 “How to Use Fire Extinguisher and Major Causes of Fire” Learning Objectives: After reading the INFORMATION SHEET, YOU MUST be able to perform on how to use fire extinguishers. Major Causes of Fires Fire protection doesn’t have to be difficult. Even the simplest things can help save you and your family from a home fire. Accidents and Carelessness Many people believe that if they are careful, they are much less likely to have a fire. While it is true that being careful will make you safer it will not stop fire from happening. Most fires are not caused from carelessness. They are caused from everyday living that is almost impossible for us to change. Electrical Wiring, Electrical Outlets and Faulty Wiring Whether it’s in an electrical outlet or a short in the wall, many fires are caused by electrical wiring. Older homes are particularly susceptible, as they were not wired for the many, many appliances that we have filled our homes with. Many homes that were built in the 50′s -70′s have aluminum wiring that gets very hot and increases the chance of fire. Date Developed: Shielded Metal Arc Welding NC II Developed by: JMCFI Document No. Page 46 of 48 pages Appliances Lamps, toasters and even baby monitors can short out. Be particularly careful with older appliances and extension cords. Even new appliances can be the source of a home fire. To be safe, appliances should be unplugged when not in use. Unfortunately, not all appliances can be unplugged, leaving your home at risk 24 hours a day. Heating Heating is another major cause of residential fire death. This is especially true in southeastern states and among wood stove users in the north. Unattended Stoves Another cause of residential fires is cooking, but not due to defective stoves or ovens. Often, it is because of unattended pots or the burner being left on accidentally -and who hasn’t done that at least once or twice. Children Playing with Matches Children and grandchildren playing with matches are a major source of home fires. According to the Burn Awareness Coalition, burns are the number one cause of accidental deaths in children under two, fire and burn injuries are the second leading cause of accidental deaths in children ages 1-4, and the third leading cause of injury and death for ages 1-18. Steps to Use Fire extinguishers It's easy to remember how to use a fire extinguisher if you can remember the acronym PASS, which stands for Pull, Aim, Squeeze, and Sweep. Pull the pin. This will allow you to discharge the extinguisher. If you aim Aim at the base of the fire. at the flames (which is frequently the temptation), the extinguishing agent will fly right through and do no good. You want to hit the fuel. Squeeze the top handle or lever. This depresses a button that releases the pressurized extinguishing agent in the extinguisher. Sweep from side to side until the fire is completely out. Start using the extinguisher from a safe distance away, then move forward. Once the fire is out, keep an eye on the area in case it re-ignites.
