Read Information Sheet 1.1 very well then find out how much you can
remember and how much you learned by doing Self-check 1.1.
Information Sheet 1.1
In every field of work, there are safety precautions and practices to be
followed to prevent accidents. Sometimes before an accident occurs a warning is
given, so the individual concerned can prepare for the undesirable eventualities.
In some situations, no warning at all is served and anyone is caught by surprise.
In areas where students are acquiring basic technical skills safety begins
the moment they enter the work area or at times before reaching that work area.
Identifying health hazards and occupational risks is indispensable. In laboratory
areas where students stay to acquire skills there are certain points to consider.
1. Electrical hazards. Electrical hazards are the type of risks that are more
likely fatal than any other hazards that can happen in a laboratory room.
Electrical hazards such as electrical shocks from open wires, grounded
electrical appliances can be found anywhere in a disorganized laboratory
area.
10
`
2. Hazards from improper use of hand tools. Hand tools are classified into
cutting tools, driving tools, boring tools, joining tools, and measuring
Cutting tools may inflict injuries when improperly handled due to its sharp
edges that can cut through the skin of the human body.
Cutter Knife
Hacksaw
Scrapper
Driving tools
Driving tools like screw drivers and hammers, when used improperly can break
human flesh or fracture bones which are very painful to an individual.
Claw hammer
Screw drivers
11
`
Boring tools
Drill bits, Center punch, and reamer are boring tools. These tools also
do damage when not properly used.
Electric drill
Drill bits with handle
Soldering tools
Soldering tools such as soldering iron, soldering gun and hot air
soldering causes extreme heat and burn in the skin when improperly used.
Soldering Iron
Soldering Gun
12
`
Measuring Tools
Multi tester is an electronic measuring instrument that combines several
measurement functions in one unit. A typical multi meter can measure voltage, current, and
resistance.
Types
Analog Multi-tester
Digital Multi-tester
Objects placed on top of a cabinet can be very dangerous to students and
teacher as well.
13
`
Other untoward incidents also happen as a result of haste and sometimes
neglect
of tools, materials, and equipment in the shop. Disorderliness can also make things worse,
hence presence of mind, particularly while working is important. It is very useful to follow
guidelines that will serve as a safety net.
The following safety rules should be understood and strictly followed to
avoid accidents while working.
1.Avoid wearing loose clothing when working. Sleeves should be fit and shirts tucked
in as much as possible. Remove ties, watches, rings, and other jewelry from your
body.
2. Report immediately injuries or accidents of any type to your teacher.
3. Never put fasteners or any small metal articles in or near the mouth when
working.
4. Never throw tools of any type around. Make sure the sharp edge of cutting tools
are away from the edge of the table or work bench.
5. Keep working areas clean and free from disposable materials.
6. Secure the help of your classmates when carrying heavy tools to avoid accidents.
7. Never use dull or damaged tools.
8. Do not use tools with loose handles and ragged. Report cases like these to the
teacher and do necessary repair and adjustments, if possible.
9. Know and observe safety measures specific for each tool or operation.
14
`
Safety Requirements
For your protection, observe the following safety requirements:
● Follow all cautions, warnings, and instructions marked on the equipment.
● Ensure that the voltage and frequency rating of the power outlet
matches the electrical rating labels on the system.
● Use properly grounded power outlets.
Information Sheet 1.2
OCCUPATIONAL HEALTH AND SAFETY PROCEDURES
Occupational Health and Safety is a planned system of working to
prevent illness and injury where you work by recognizing and
identifying hazards and risks.
OCCUPATIONAL HEALTH AND SAFETY POLICIES and PROCEDURE
Occupational Health and Safety (OHS) is a cross-disciplinary area concerned with
protecting the safety, health and welfare of people engaged in work. The goal is to promote
a safe work environment. It may also protect co-workers, family members, employers,
customers, suppliers, nearby communities, and other members of the public who are
impacted by the workplace environment. As Consumer Electronic Servicing National
Certificate Level II (CES NC II) student, you should know how to conduct yourself when
working in the classroom/ laboratory room, as well as implement a safe way of
accomplishing every task. Safety practices should be learned early and always adhered to
15
`
when working with any electrical and electronic device. This is for your protection as well
as of the people working with you, and also for the devices that you are using. The basis
for this process begins with Occupational Health and Safety Policies.
Personal Safety While Working Along Electronic Circuits
Electronics equipment can be dangerous, and you or others can be injured or
even killed if you don’t follow proper safety guidelines when working or servicing these
circuits. The following are some precautionary measures to take before working with any
electrical/ electronic circuits:
 Wear shoes with non-conductive rubber soles to help reduce the chance of being
shocked or seriously injured in an electrical accident.
 Do not work on components that are plugged into their power source.
 Do not remove expansion cards from electronic product when it is turned on.
 Remove jewelries when working inside any electronic related equipment.
 Be sure not to merge electronic components and water.
Safety Requirements with the Use of Personal Protective Equipment
Hand Tool Design, Selection, and Setup
1. Weight - Use the lightest weight tool possible to avoid injury. Excessively heavy tools
must be equipped with mechanical support and attached hoses should be supported.
Support - Equip tools with some means of mechanical support so you don't need to hold a
heavy tool continuously while working. If mechanical support cannot be provided, the
workstation should be designed so you can put the tool down or rest it in a holster when it
is not in use.
16
`
2. Balance - Additional force is required to use an unbalanced tool. The tool's center of
gravity should be close to the body, close to the handles, and in line with the center of the
hand holding the tool.
3. Torque Control - High torque requires a lot of force to keep the tool from rotating out of
your hand. Torque settings should be set to the minimum required by job specifications,
especially for in-line and pistol-shaped tools.
4. Grip - Tool handles should allow stable and efficient grip. The handle should be
cylindrical or oval in shape, with a diameter of between 1.25 and 1.75 inches. Tool handles
should contact as much of the hand and fingers as possible. Grips should be made of nonslip compressible and nonconductive material. Avoid form-fitting handles (handles with
finger grooves), since they may not fit the hand size of every user. Handles should be kept
clean and free from slippery grease, oil, or sweat.
17
`
5. Span - On two-handled manual tools, like pliers, the open span should be about 4 inches
and the closed span should only be about 1.5 inches.
6. Spring-loaded handles - A spring-loaded mechanism saves muscular effort and
reduces mechanical stress on the backs and sides of fingers for such tools as scissors,
pliers, and other manual cutting and gripping tools which have to be opened and closed
repeatedly during use
7. Choose the right tool shape - Pistol-shaped tools should be used on a vertical surface
or on a horizontal surface below waist height. Bend the tool, not the wrist.
18
`
8. Avoid bending over your work.
9. Avoid overhead work if possible. Use a ladder to reduce the need for outstretched
arms.
10. Keep the elbows close to the body.
19
`
11. Tilt the work surface instead of the wrist.
12. Stand with weight evenly distributed on both feet. When standing for long periods of
time, rest one foot on a sturdy object above floor height and switch legs periodically.
13. Sit up straight so the chair offers good back support. Adjust the chair back so it
comfortably supports the natural curve of the lower back. Adjust the seat height to allow
thighs to be parallel to the floor.
20
`
Three Think Safe Steps:
1. SPOT THE HAZARD- A hazard is anything that could hurt you or someone else.
2. ASSESS THE RISK- It means working out how likely it is that a hazard will harm
someone and how serious the harm could be.
3. MAKE THE CHANGES- For example, you can pick things from the floor and put
them away to eliminate a trip hazard.

Information Sheet 1.3
PERSONAL PROTECTIVE EQUIPMENT
It is the employer’s responsibility to provide personnel protective clothing and
equipment. It includes work clothes and specially designed protective clothing intended for
your protection. Wear the correct clothing and equipment to protect you
from possible serious injury. Do not interfere with or misuse any item provided for health
and safety. Personal Protective Equipment (PPE) is defined in the Occupational
Safety and Health Administration (OSHA) as a tool used to protect workers from injury
or illness caused by having contact with the dangers (hazards) in the workplace, whether
they are chemical, biological, radiation, physical, electrical, mechanical and other.
Exposures to hazards are reduced using PPE. The types of Personal Protective Equipment
Personal Protective Equipment can be classified according to target organs potentially
affected of the risk of danger. Identification of hazard and risk assessment of a job, process
and activity must be done first before deciding which type of PPE to be used.

 Wear clothes that are tight, plain, and well-built and keep them buttoned up. –
Loose sleeves, unbuttoned or torn shirts or sweaters, ties or loose belts can easily
be caught in revolving machinery.
 Wear cuff less trouser. - Trouser cuffs may cause you to trip or they may catch
sparks or harmful substances.  Wear suitable footwear and keep it in good repair
 Wear safety shoes or boots with insulated sole for electrical work. - Safety shoes
and boots will reinforce toe caps to protect against heavy falling objects.
 Keep long hair under a tightfitting cap or net. If your hair is long, it can be easily
caught by the machine.
24
`
 Do not wear accessories such as rings or wrist watches, earrings, neck chains,
pendants and bracelets while on the job.
- Such items can be caught by moving machinery. It is extremely dangerous to
wear them in certain types of work. You may lose your fingers
 Wear personal protective equipment suitable to the kind of work to be done. –
Learn the purpose of each item from the wide range of protective devices
available.
How is Electrostatic Discharge (ESD) Generated?
Static charge is a form of electricity at rest. It can be generated by simple friction
that is, rubbing two objects together. A simple method of generating a static charge is to
rub a plastic ball pen case on a nylon cloth. Once generated, the static electricity will remain
on the ball pen for as long as it is not placed on any other charged materials. If ever the
ball pen comes in contact with another object, the static electricity can move to or from the
ball pen to equalize the charge between the two objects. The transfer of static electricity
from any of the two objects is called electro-static discharge. One inexhaustible source of
electrons that can supply or can accept them without any effect is the earth. Whatever
charged object brought into it is immediately discharged.
ESD wrist straps ESD wrist straps
are also called conductive wrist straps or bands. They are usually made of elastic
cloth but contain conductive strands that touch your skin and discharge any static electricity
on your body. Some straps are made of conductive rubber. The wire attached to the strap
containing a large value resistor usually one mega ohm (1,000,000 ohms). It allows any
charge on your body to be slowly transferred to a washing machine ground point.
ESD Protection Procedure
1. Anti-static kit can be purchased from a computer or electronics store. The main
component is an ESD wrist strap with a wire several feet long having an
alligator clip at the other end.
2. Before troubleshooting any domestic appliance, wear an ESD wrist strap and
wear it as you go under the covers, handle ICs, and circuit boards.
25
`
3. Put the adjustable strap around your wrist. If you are wearing an ESD wrist
strap connected to frame or ground, it drains static charges of your body, thus,
it prevents damaging ESD sensitive devices.
4. Attach the clip at the end of the wire to an electrical ground connection or
metal framework of the appliance. 5. If you work on a appliance without a
conductive wrist strap, touch an electrical appliance such as a lamp or the
screw in a wall outlet cover plate before touching the PCB. An electrostatic
discharge of just a few hundred volts is too small to feel in most cases but can
be usually deadly to ESD sensitive devices.
Also avoid wearing clothes that easily produce a static charge, such as
knits and wools and limit your movements as much as possible, especially on
carpets while working on electronic circuits of a washing machine.

GOOD HOUSEKEEPING AND WORKPLACE ORGANIZATION 5’S
5S or good housekeeping involves the principle of waste elimination
through workplace organization. 5S was derived from the Japanese words
seiri, seiton, seiso, seiketsu, and shitsuke. In English, they can be roughly translated
as sort, set in order, clean, standardize, and sustain.
What Is the 5’S System?
The 5S system is a lean manufacturing tool that improves workplace efficiency and
eliminates waste. There are five steps in the system, each starting with the letter S:
1. Sort
2. Set In Order
3. Shine
4. Standardize
5. Sustain
By providing a systematic framework for organization and cleanliness, 5S helps facilities
avoid lost productivity from delayed work or unplanned downtime.
27
`
The Steps of 5S
5S was created in Japan, and the original “S” terms were in Japanese, so English
translations for each of the five steps may vary. The basic ideas and the connections
between them are easy to understand, though.
Step Name
Japanese term
1. Sort
Seiri (tidiness)
2. Set In Order
Seiton (orderliness)
3. Shine
4.Standardize
5. Sustain
Explanation
Remove unnecessary items from each area
Organize and identify storage for efficient
use
Seiso (cleanliness)
Clean and inspect each area regularly
Seiketsu
Incorporate 5S into standard operating
(standardization)
procedures
Shitsuke (discipline)
Assign responsibility, track progress, and
continue the cycle
These steps feed into each other, so the sequence is important.
Step 1: Sort
The first step in the 5S process is Sort, or “seiri,” which translates to “tidiness.” The goal
of the Sort step is to eliminate clutter and clear up space by removing
things that don’t belong in the area..
Red-Tagging Unknown Items
28
`
Step 2: Set In Order
The second step, Set In Order, was originally called “seiton,” which translates to
“orderliness.” A variety of names have been used in English: “Systematic Organization,”
“Straightening Out,” and “Simplify,” for example. No matter what it’s called, the goal of this
step is to organize the work area. Each item should be easy to find, use, and return: a place
for everything, and everything in its place.
Building a 5S Map
Step 3: Shine
The third step of 5S is Shine, or “seiso,” which means “cleanliness.” While the first and
second steps cleared up space and arranged the area for efficiency, this step attacks the
dirt and grime that inevitably builds up underneath the clutter, and works to keep it from
coming back.
Routine Cleaning
29
`
Step 4: Standardize
The first three steps of 5S cover the basics of clearing, organizing, and cleaning a work
space; on their own, those steps will provide short-term benefits. The fourth step is
Standardize, or “seiketsu,” which simply means standardization. By writing down what is
being done, where, and by whom, you can incorporate the new practices into normal work
procedure. This paves the way for long-term change.
The Power of Writing Things Down
Step 5: Sustain
The fifth step of a 5S program is Sustain, or “shitsuke,” which literally means
“discipline.” The idea here is continuing commitment. It’s important to follow through on the
decisions that you’ve made — and continually return to the earlier steps of 5S, in an ongoing
cycle.
Sustaining a 5S program can mean different things in different workplaces, but there are
some elements that are common in successful programs.
30
`
Management support – Without visible commitment from
managers, the 5S processes won’t stick around. Supervisors
and managers should be involved in auditing the 5S work
processes, and getting feedback from workers. They also
need to provide the tools, training, and time for workers to get
their jobs done right.
Department tours – Bringing teams from one department to
visit other departments will help familiarize the entire
workforce with the processes of your facility. This type of
“cross pollination” helps to spread good ideas, and inspires
people to come up with new ways to improve the 5S
implementation.
Updated training – As time passes, there may be changes in
your workplace, such as new equipment, new products, or
new work rules. When this happens, revise your 5S work
standards to accommodate those changes, and provide
training on the new standards.
Progress audits – The standards that are created in the 5S
program should provide specific and measurable goals.
Checking on those goals with a periodic audit can provide
important information and guidance. Where is 5S working
well? Where are teams falling behind?
Performance evaluations – Once you know your goals are
reasonable, make performance part of each employee
evaluation. When teams and individuals perform well,
celebrate it, and post overall results so each team can see
how they compare to the rest of the facility.
31
`
Benefits of a 5S Program
Because 5S focuses on improving a workplace, and different workplaces may have little in
common, it can be hard to predict the exact results of using the program. However, some
benefits are almost always found:
Better time usage - Getting rid of unwanted materials and
organizing the important tools and supplies will eliminate
clutter and confusion. Workers spend less time finding and
retrieving what they need, and can be more productive instead.
Less wasted space – Eliminating unnecessary material
stockpiles and consolidating tool storage will clear up room for
more useful applications. Every square foot of floor space has
a cost, and getting the most out of that investment will
maximize your facility’s profitability.
Reduced injury rates – Organizing work areas for efficiency
and ease of use will reduce the movements needed for
workers to do their jobs. Removing clutter and routinely
cleaning up spills will eliminate trip hazards. As a result,
workers will experience less fatigue and fewer injuries.
Reduced equipment downtime – When tools and equipment
are kept clean, routinely inspected, and used in a standardized
way, preventative maintenance is much easier, and major
failures can often be prevented entirely.
32
`
Improved consistency and quality – Standardizing work
processes will reduce variations and mistakes. By eliminating
faults and failures, overall productivity can be dramatically
improved.
Heightened employee morale – When 5S principles are used
effectively, workers see that their input is valued, and their
performance is recognized. This creates an environment
where workers can feel pride in their work, and take an interest
in improving their company.
These benefits are not just good feelings. By documenting their situations before and after
adopting 5S, many facilities have been able to show actual, measured improvements.
