General hazards that apply to the operation of all or most welding and cutting equipment. See Appendix A for Company-specific hazards of our welding and cutting equipment and our workplace. Each potential welder or cutter who has received training in any of the elements of our training program for the types of equipment which that employee will be authorized to operate and for the type of workplace in which the welding and cutting equipment will be operated need not be retrained in those elements before initial assignment in our workplace if the company has evaluated and found that the employee is competent to operate the equipment safely. Training is done: 1. In-house training. See the attached current copy of the training material and the course outline. 2. Training by an outside vendor. See the attached information about the outside company and their training materials. Training Certification After an employee has completed the training program, the instructor will determine whether the potential welder or cutter can safely perform the job. At this point, the trainee will take a performance test or H E & R 2005 3 Rev. 2012 practical exercise through which the instructor(s) will decide if the training has been adequate. All welding and cutting trainees are tested on the equipment they will be operating. The Corporate Safety Manager is responsible for keeping records certifying each employee who has successfully completed training and testing. Each certificate includes the name of the employee, the date(s) of the training, the date of the evaluation, and the identity of the person who did the training and evaluation. Performance Evaluation Each certified welder or cutter is evaluated to verify that the welder or cutter has retained and uses the knowledge and skills needed to operate safely. The Corporate Safety Manager does this evaluation. Refresher Training Refresher training required if: 1. The welder/cutter is involved in an accident or near miss incident; 2. The welder/cutter has been observed performing unsafely; 3. When the welder/cutter is assigned to a different type of equipment; 4. It is determined during an evaluation that the welder/cutter needs additional training; or 5. When there are changes in the workplace that could affect safe operation of equipment, retraining is performed. Current Welders and Cutters Under no circumstances may an employee operate welding or cutting equipment until he/she has successfully completed the Company’s welding and cutting training program. All new welders or cutters must undergo a performance evaluation, regardless of their level of experience. The following table lists employees who are currently authorized welders and cutters at this company: Department or work area Maintenance Maintenance Employee name/title Sam Holley/Welder Paul Reiber/ Welder Equipment make and model All All All employees have a responsibility to work safely with and around welding and cutting operations. Operating Procedures Welding and cutting can create certain hazards that only safe work practices can prevent. The Company has created a set of operating procedures to promote safe work practices and to eliminate certain hazards associated with welding and cutting. These operating procedures include: Electrical Equipment • Employees should not arc weld while standing on damp surfaces or in damp clothing. • Employees should properly ground, install, and operate equipment. • Employees should not use defective equipment. • Employees should use well-insulated electrode holders and cables. • Employees should insulate themselves from both the work and the metal electrode and holder. • Employees should not wrap a welding cable around your body. • Employees should wear dry gloves and rubber-soled shoes. H E & R 2005 4 Rev. 2012 • Employees should not use damaged or bare cables and connectors. • In case of electric shock, Employees should not touch a victim. Employees should turn off the current at the control box and then call for help. After the power is off, employees may perform cardiopulmonary resuscitation (CPR) if necessary. Personal Protective Equipment • Proper eye protection i.e., helmets, hand shields, goggles, and spectacles, must be provided. • Proper protective clothing must be provided. • First-aid equipment shall be available at all times. • Air line respirators will be provided for confined space jobs when sufficient ventilation cannot be provided without blocking the exit. • When known or unknown toxic materials are present in a job, respirators will be provided that match the hazard for all employees. The hazards include zinc or zinc-bearing base or filler metals, lead base metals, cadmium-bearing filler metals, chromium-bearing or chromium-coated metals, mercury, nitrogen dioxide, and beryllium. Due to beryllium’s extreme danger, both ventilation and air-line respirators will be used. • Where screens are not sufficient to protect welders and passersby from arc radiation, the Company will provide eye protection with appropriate helmets, filter lens goggles, or hand shields. The helmets and shields will be maintained in good repair. • When a toxic preservative is detected on a surface in a confined space, air line respirators will be provided (or the toxic coating will be stripped from at lest four inches around the heated area.) Compressed Gas Cylinders • Handling, storage, and use of compressed gases around the workplace represent a number of potential hazards. Questions regarding the handling, storage and use of compressed gases are by supervisors and/or the Compressed Gas Association Pamphlet P-1-1965. • Approved practices include: 1. Employees should keep valve protection cap in place at all times when a cylinder is not in use. 2. Employees should use care in handling and storage of cylinders, safety valves, relief valves, etc., to prevent damage. 3. When cylinders are hoisted, employees should secure them on a cradle, slingboard, or pallet. 4. Employees should move cylinders by tilting and rolling them on their bottom edges. Care in handling is required. 5. Employees should secure cylinders in an upright position at all times, especially when moving them by machine. 6. Employees should use carriers or carts provided for the purpose when cylinders are in use. 7. Employees should when in use, isolate cylinders from welding or cutting or suitable shield them. Care will be taken to prevent them from becoming part of an electrical circuit. 8. Employees should maintain a distance of at least 20 feet or provide a non-combustible barrier at least five feet high in separating fuel gas cylinders form oxygen cylinders. This applies to indoor and outdoor storage. 9. The supervisor will designate: well-ventilated storage areas for cylinders inside buildings. Care will be taken to keep storage areas out of traffic areas or other situations where they could be knocked over, damaged, or tampered with; locations for fuel gas and oxygen manifolds in well-ventilated areas. 10. Before a regulator is removed, employees should check that the valve is closed and the gas released form the regulator. H E & R 2005 5 Rev. 2012 11. Employees should keep cylinders, cylinder valves, couplings, regulators, hoses, and apparatus free of oily or greasy substances. 12. Employees should keep empty compressed gas cylinders appropriately marked and their valves closed. 13. Employees should store full and empty cylinders apart. 14. Employees should group cylinders by type of gas. 15. Employees should use old stock before newer stock. • Prohibited practices include: 1. Employees should not use of valve protection caps for lifting cylinders. 2. Employees should not use of damaged or defective cylinders. The plant manager will provide appropriate tags and designate an appropriate storage area for these cylinders. 3. Employees should not use a wrench or hammer to open cylinder valves. 4. Employees should not attempt to repair a cylinder valve. The supplier should be contacted. 5. Employees should not mix gases. 6.Employees should not use a magnet or choker sling when hoisting cylinders. 7.Employees should not use a bar to pry cylinders form frozen ground. Warm, not boiling, water is used to thaw cylinders. 8.Employees should not take oxygen, acetylene, or other fuel gas or manifolds with these gases into confined spaces. 9.Employees should not store cylinders near elevators, stairs, or gangways. • Using cylinders as rollers or supports. Fire Prevention 1. The supervisor will assess fire hazards within the Company. 2. If the object to be welded or cut cannot readily be moved, all movable fire hazards in the vicinity shall be taken to a safe place. 3. If the object to be welded or cut cannot be moved and if all the fire hazards cannot be removed, then guards shall be used to confine the heat, sparks, and slag, and to protect the immovable fire hazards. 4. If the requirements stated in two and three above cannot be followed then welding and cutting shall not be performed. 5. Wherever there are floor openings or cracks in the flooring that cannot be closed, employees should take precautions so that no readily combustible materials on the floor below will be exposed to sparks, which might drop through the floor. The same precautions shall be observed with regard to cracks or holes in walls, open doorways, and open or broken windows. 6. Suitable fire extinguishing equipment shall be provided and maintained in a state of readiness for instant use. Such equipment may consist of pails of water, buckets of sand, hose or portable extinguishers depending upon the nature and quantity of the combustible material exposed. 7. Before cutting or welding is permitted, the employee responsible for authorizing cutting and welding operations shall inspect the area. The employee shall designate precautions to be followed in granting authorization to proceed preferable in the form of a written permit. 8. Special precautions shall be taken for floors covered with combustible materials; combustibles within 35 feet of the work area; ducts that might carry sparks; combustible walls; combustibles on the other side of a noncombustible wall; combustible coverings; pipes in contact with combustible walls; storage of readily ignitable materials; drums barrels, tanks other containers that may contain flammable materials; pipes leading to a drum or vessel; and all hollow spaces, cavities or containers. 9. The Company will designate an employee to be responsible for authorizing welding operations in areas not designed for such processes. H E & R 2005 6 Rev. 2012 10. The Company will advise all contractors about flammable materials or hazardous conditions. 11. Cutting or welding shall not be permitted in the following situations: In areas not authorized by management. In sprinklered buildings while such protection is impaired. In the presence of explosive atmospheres (mixtures of flammable gases, vapors, liquids, or dusts with air), or explosive atmospheres that may develop inside unclean or improperly prepared tanks or equipment which have previously contained such materials, or that may develop in areas with an accumulation of combustible dusts. Fire Watchers Fire watchers shall be required when: • Welding or cutting is performed in locations where other than a minor fire might develop, or any of the following conditions exist. • There is an appreciable combustible material, in building construction or contents, closer than 35 feet (10.7m) to the point of operation. • There is appreciable combustibles are more than 35 feet (10.7m) away but are easily ignited by sparks. • Wall or floor openings within a 35-foot (10.7m) radius expose combustible material in adjacent areas including concealed spaces in walls or floors. • Combustible materials are adjacent to the opposite side of metal partitions, walls, ceilings, or roofs and are likely to be ignited by conduction or radiation. • Fire watchers shall have fire extinguishing equipment readily available and be trained in its use. • Fire watchers will be trained on the specific fire hazards. • Fire watchers must remain at the site at least a half-hour after completion of welding or cutting operations to detect and extinguish possible smoldering fires. Gas Welding and Cutting Safe practices in using fuel gas include: • Before a regulator to a cylinder valve is connected, employees should “crack” the valve to clear it of dust or dirt. Employees should stand to one side of the outlet, not in front of it. Employees should not do this where the gas would reach welding work, sparks, flame, or other possible sources of ignition. • Employees should open cylinder valves slowly to prevent damage to the regulator. For quick closing, do not open valves on fuel gas cylinders more than 1 ½ turns. When a special wrench is required, leave it in position on the valve stem while the cylinder is in use. In the case of manifold or coupled cylinders, make sure at least one such wrench is always available for immediate use. • Employees should not place anything on top of a fuel gas cylinder, when in use, which may damage the safety device or interfere with quick closing. • Employees should not use fuel gas directly from cylinders through torches or other devices equipped with shutoff valves without reducing the pressure through a suitable regulator. • Before a regulator is removed from a cylinder valve, employees should always close the cylinder valve and release the gas from the regulator. • If the gas leaks around the valve stem, employees should close the valve and tighten the gland nut. If this does not work, employees should not use the cylinder, but properly tag it and remove it from the work area. H E & R 2005 7 Rev. 2012 • • • • • If fuel gas leaks from the cylinder valve and the gas cannot be shut off, employees should properly tag and remove the cylinder from the work area. If a regulator will effectively stop a leak through the valve seat, the cylinder can be used. Employees should not use oxygen for personal cooling, cleaning off of surfaces, ventilation, or blowing dust from clothing. Employees should not weld or cut an acetylene or oxygen pipeline, including the attachment of hangers or supports, until the line has been purged. Employees should only use pressure-reducing regulators for gas and pressures for which they are intended. Employees should not attempt to repair a regulator or parts of a regulator. Have a skilled mechanic do so. Safe practices in using torches include: • Employees should clean clogged tip openings only with suitable cleaning wires, drills, or other devices designed for such purpose. • Employees should inspect at the beginning and end of each shift for leaking shutoff valves, hose couplings, and tip connections. Do not use defective torches. • Employees should light only with friction lighters or other approved devices. Do not use matches or hot work. Safe practices in using regulators and gauges include: • Employees should make sure oxygen and fuel gas pressure regulators, including their related gauges are in proper working order. • Employees should keep oxygen cylinders and fittings away from oil or grease. Oxygen shall not be directed at oily surfaces, greasy clothes, or within a fuel oil or other storage tank or vessel. Arc Welding and Cutting • When arc welding is performed in wet conditions, or under conditions of high humidity, special protection against electric shock shall be supplied. • Employees should not dip a hot electrode into water. • Employees should use holders, cable, and other apparatus specifically designed for the purpose, matched to the job and other components and in good repair. • When leaving electrode holders unattended, electrodes must be removed and holders placed so that accidental electrical contact is not made. • Employees should use non-combustible or flame-proof screens to protect employees and passersby from arc rays whenever possible. • Employees assigned to operate or maintain gas-shielded arc welding equipment shall be acquainted with the requirements of American Welding Society, A6.1-1966, Recommended Safe Practices for Gas-Shielded Arc Welding. • Before starting operations all connections to the machine shall be checked to make certain they are properly made. The work lead shall be firmly attached to the work; magnetic work clamps shall be freed from adherent metal particles of spatter on contact surfaces. Coiled welding cable shall be spread out before use to avoid serious overheating and damage to insulation. • Grounding of the welding machine frame shall be checked. Special attention shall be given to safety ground connections of portable machines. • There shall be no leaks of cooling water, shielding gas, or engine fuel. H E & R 2005 8 Rev. 2012 • • • • • • • It shall be determined that proper switching equipment for shutting down the machine is provided. Printed rules and instructions covering operation of equipment supplied by the manufacturers shall be strictly followed. Electrode holder when not in use shall be so placed that they cannot make electrical contact with persons, conducting objects, fuel, or compressed gas tanks. Cables with splices within 10 feet (3m) of the holder shall not be used. The welder should not coil or loop welding electrode cable around parts of his or her body. The operator should report any equipment defect or safety hazard to his supervisor and the use of the equipment shall be discontinued until its safety has been assured. Only qualified personnel shall make repairs. Machines that have become wet shall be thoroughly dried and tested before being used. Cables with damaged insulation or exposed bare conductors shall be replaced. Joining lengths of work and electrode cables shall be done by the use of connecting means specifically intended for the purpose. The connecting means shall be insulation adequate for the service conditions. Ventilation • The supervisor will determine the number, location, and capacity of ventilation devices. • Ventilation will be sufficient to protect passersby as well as the welder. • Oxygen shall never be used for ventilation. • Employees should not rely on general ventilation as the only means of protection when air contaminants are toxic. • Where ventilation is not sufficient to provide clean, breathable air, respirators will be specified according to specifications listed in the Personal Protective Equipment row of this table. Confined Spaces • Employees should evaluate the space, the hazardous atmosphere, the floor surface, and the interior surface for flammability, combustibility, or toxic fumes that could result from the welding process. • Employees should perform atmospheric testing for testing for oxygen deficiency, and for toxic and flammable or combustible gases before and during entry. If the tests show that flammable or combustible gases are present, the space must be ventilated until safe to enter. If the atmosphere is toxic and cannot be cleared through ventilation, appropriate respiratory equipment must be used. All energy sources that could cause employee injury must be disconnected and locked in the “off” position before entry. • Gas cylinders and welding machines shall be left on the outside of the confined space. Before operations are started, heavy portable equipment mounted on wheels shall be securely blocked to prevent accidental movement. • Where a welder must enter a confined space through a manhole or other small opening, means shall be provided for quickly removing him in case of emergency. When safety belts and lifelines are used for this purpose they shall be so attached to the welder’s body so that his or her body cannot be jammed in a small exit opening. An attendant with a preplanned rescue procedure shall be stationed outside to maintain communication with the welder at all times and be capable of putting rescue operations into effect. • When arc welding is to be suspended for any substantial period of time, such as during lunch or overnight, all electrodes shall be removed from the holders carefully located so that accidental contact cannot occur and the machine disconnected from the power source. H E & R 2005 9 Rev. 2012 • • In order to eliminate the possibility of gas escaping through leaks of improperly closed valves, when gas welding or cutting, the torch valves shall be closed and the fuel-gas and oxygen supply to the torch positively shut off at some point outside the confined area whenever the torch is not to be used for a substantial period of time, such as during lunch hour or overnight. Where practicable the torch and hose shall also be removed from the confined space. After welding operations are completed, the welder shall mark the hot metal or provide some other means of warning other workers. Flammable, Toxic, or Hazardous Materials • The Company will designate an employee who is responsible for testing the flammability of unknown coatings. • When a coating is found to be highly flammable, it will be stripped from the area to prevent fire. Slip, Trip, and Fall Protection • A welder or helper working on platforms, scaffolds, or runways shall be protected against falling. This may be accomplished by the use of railings, safety belts, lifelines, or some other equally effective safeguards. • Welders shall place welding cable and other equipment so that it is clear of passageways, ladders, and stairways. • Employees should maintain a clear welding or cutting area to prevent slips, trips, and falls.

H E & R 2005 12 Rev. 2012 Maintenance Any deficiencies found in the Company welding and cutting equipment are repaired, or defective parts replaced, before continued use. However, no modifications or additions that affect the capacity of safe operation of the equipment may be made without the manufacturer’s written approval. If such modifications or changes are made, the capacity, operation, and maintenance instruction plates, tags, or decals, must be changed accordingly. In no case may the original safety factor of the equipment be reduced. While defective parts may be found, we prefer to invest time and effort into the proper upkeep or our equipment, which results in day-to-day reliability. The Company compiles with the manufacturer’s recommended maintenance schedules, and complete the proper records, which not only increases the longevity of welding and cutting equipment but also its day to day reliability. The Corporate Safety Manager completes(s) a receiving or delivery inspection whenever the Company purchases welding and cutting equipment. Welders follow the manufacturer’s operator instruction manual for daily or weekly maintenance. See attached manufacturer’s operator instruction manual(s). Periodic maintenance (those completed monthly or less frequently) is done by a factory-trained expert, or a dealer. Signs and Labels The Company uses the following signs: 1. After welding operations are completed, all welders must mark the hot metal or provide some other means of warning other workers. 2. A warning should be placed near cylinders having leaking fuse plugs or other leaking safety devices not to approach them with a lighted cigarette or other source of ignition. Such cylinders should be plainly tagged; the supplier should be promptly notified and his instructions followed as to their return. 3. The following sign shall be conspicuously posted at each manifold: Low-Pressure Manifold Do Not Connect High-Pressure Cylinder Maximum Pressure-250 psig (1.7 MPa) 4. Aboveground piping systems shall be marked in accordance with the American National Standard Scheme for the Identification of Piping Systems, ANSI A13.1-1956, which is incorporated by reference as specified in 29 CFR 1910.6. 5. Station outlets shall be marked to indicate the name of the gas. 6. Acetylene generators shall be of approved construction and shall be plainly marked with the maximum rate of acetylene in cubic feet per hour for which they are designed; the weight and size of carbide necessary for a single charge; the manufacturer’s name and address; and the name or number of they type of generator. 7. Operating instructions shall be posted in a conspicuous place near the generator or kept in a suitable place available for ready reference. H E & R 2005 13 Rev. 2012 The Company uses the following labels: 1. Lenses shall bear some permanent distinctive marking by which the source and shade may be readily identified. 2. Precautionary labels. A number of potentially hazardous materials are employed in fluxes, coatings, coverings, and filler metals used in welding and cutting or are released to the atmosphere during welding and cutting. The suppliers of welding materials shall determine the hazard, if any, associated with the use of their materials in welding, cutting, etc. 3. All filler metals and fusible granular materials shall carry the following notice, as a minimum, on tags, boxes, or other containers: CAUTION Welding may produce fumes and gases hazardous to health. Avoid breathing these fumes and gases. Use adequate ventilation. See ANSI Z49.1-1967 Safety in Welding and Cutting published by the American Welding Society. 4. Brazing (welding) filler metals containing cadmium in significant amounts shall carry the following notice on tags, boxes, or other containers: WARNING CONTAINS CADMIUM-POISONOUS FUMES MAY BE FORMED ON HEATING Do not breathe fumes. Use only with adequate ventilation such as fume collectors, exhaust ventilators, or air-supplied respirators. See ANSI Z49.1-1967. If chest pains, cough, or fever develops after use call physician immediately. 5. Brazing and gas welding fluxes containing fluorine compounds shall have a cautionary wording to indicate that they contain fluorine compounds. One such cautionary wording recommended by the American Welding Society for brazing and gas welding fluxes reads as follows: CAUTION CONTAINS FLUORIDES This flux when heated gives off fumes that may irritate eyes, nose and throat. Avoid fumes-use only in well-ventilated spaces. Avoid contact of flux with eyes or skin. Do not take internally. 6. Compressed gas cylinders shall be legibly marked, for the purpose of identifying the gas content, with either the chemical or the trade name of the gas. Such marking shall by means of stenciling, stamping, or labeling, and shall not be readily removable. Whenever practical, the marking shall be located on the shoulder of the cylinder. This method conforms to the American National Standard Method for Marking Portable Compressed Gas Containers to Identify the Material Contained, ANSI Z48.1-1954, which is incorporated by reference as specified in 29 CFR 1910.6. 7. Gages on oxygen regulators shall be marked “USE NO OIL.” 8. The total hourly output of a generator shall not exceed the rate for which it is approved and marked. Unless specifically approved for higher ratings, carbide-feed generators shall be rated at 1 cubic foot per hour per pound of carbide required for a single complete charge. 9. Packages containing calcium carbide shall be conspicuously marked “Calcium CarbideDangerous If Not Kept Dry” or with equivalent warning. H E & R 2005 14 Rev. 2012 10. Terminals for welding leads should be protected from accidental electrical contact by personnel or by metal objects, i.e., vehicles, crane hooks, etc. Protection may be obtained by use of : Dead-front receptacles for plug connections; recessed openings with non-removable hinged covers; or heavy insulating sleeving or taping or other equivalent electrical and mechanical protection. If a welding lead terminal which is intended to be used exclusively for connection to the work is connected to the grounded enclosure, it must be done by a conductor at least two AWG sizes smaller than the grounding conductor and the terminal shall be marked to indicate that it is grounded. Record Keeping The Corporate Safety Manager is responsible for maintaining the following records: 1. Authorization permits: before cutting or welding is permitted, the employee responsible for authorizing cutting and welding operations shall inspect the area. The employee shall designate precautions to be followed in granting authorization to proceed preferably in the form of a written permit. 2. Rules and instructions for operation and maintenance of oxygen or fuel-gas supply equipment: Employees in charge of the oxygen or fuel-gas supply equipment, including generators, and oxygen or fuel-gas distribution piping systems shall be instructed and judged competent by the Company for this important work before being left in charge. Rules and instructions covering the operation and maintenance of oxygen or fuel-gas supply equipment including generators, and oxygen of fuel-gas distribution piping systems shall be readily available. 3. Trouble reports: Cylinder valves shall not be tampered with nor should any attempt be made to repair them. If trouble is experienced, the supplier should be sent a report promptly indicating the character of the trouble and the cylinders serial number. Supplier’s instructions as to its disposition shall be followed. 4. Operating instructions: Operating instructions shall be posted in a conspicuous place near the generator or kept in a suitable place available for ready reference. 5. Certification records for resistance welding equipment: Periodic inspection shall be made by qualified maintenance personnel, and a certification record maintained. The certification record shall include the date of inspection, the signature of the person who performed the inspection and the serial number, or other identifier, for the equipment inspected. The operator shall be instructed to report any equipment defects to his or her supervisor and the use of the equipment shall be discontinued until safety repairs have been completed. These records are maintained in the Safety Office.
