SAFETY PROCEDURES
Learning Objectives:
After the discussion, YOU MUST able to:
1. Identify hazard risks
2. Evaluate hazard risks
3. Control hazard risk
4. Maintain occupational health and safety
awareness.

SAFETY PROCEDURES
Here are some safety precautions to take before
working with any computer devices:
Before doing anything, listen to your teacher’s instruction to
prevent accidents or any unwanted events that may occur
on your workplace.
Ensure a clean, well-lit, and organized workspace.
Do not work on computer when you are wet because you
might get electrocuted.
Do not remove internal devices of the computer when it is
turned on.

SAFETY PROCEDURES
Here are some safety precautions to take before
working with any computer devices:
Wear appropriate PPE like anti-static gloves, safety goggles,
and closed-toe shoes to protect against potential hazards
Handle computer parts with care, especially fragile
components like CPUs, RAM modules, and GPUs.
Avoid touching sensitive parts (such as gold connectors)
directly and hold components by their edges.

SAFETY PROCEDURES
Here are some safety precautions to take before working
with any computer devices:
Organize cables neatly to prevent tripping hazards and to
ensure proper airflow within the computer case.
Avoid playing or running while inside the room.
Ask for assistance from your teacher when it comes on
dealing with computer devices.

BASIC HAND TOOLS AND MATERIALS
1. Identify basic hand tools and materials used in computer
configuration.
2. Identify usage of each tool and device for the
configuration process.
3. Distinguish which is a material, a tool and a testing
device.

These are the following materials needed in the Configuration
task:
1. Connectors - It is used to connect external devices to the
computer system.

2. Adapter - A piece of hardware device used for connecting two
nonmatching parts.

3. Wires and Cables - It is used to connect computers for
network.

4. Application Software - - This software packages are used to
install new drivers needed in setting up your computer.

5. Computer storage media - These help you in saving data and
providing backup for your files such as external hard disk,
compact disc, flash drives and memory cards.

6. Reference book - These are books that will provide topics
about networking or related books on computer.

These are the following tools/ testing devices needed in the
configuration tasks:
1. Screw drivers
Flat screw driver is used to fasten negative slotted Screws.
 Philips Screw driver is used to fasten positive slotted screws.

2. Pliers
 Side Cutter pliers - are used for cutting and trimming of
connecting wires or terminal leads in the circuit board.
 Long nose pliers - are used for holding, bending and
stretching the lead of electronics component and connecting
wire.

5. Magnifying glass − It is a device made of glass with handle. It
exaggerates or increases the apparent size of an object.
6. Safety apparel suit (coverall) - It is used by the person for
body protection.

7. Anti-static wrist strap - It absorbs the
static electricity of the material when
being hold by the hands.
8. Tweezers - It is used to hold the small sensitive part of the
computer.

9. Mini-vacuum cleaner - It is used for
cleaning sensitive parts of the computer.
10.Crimping Tool & Wire Stripper – it is used for crimping
network cables.

PC Assembly / Disassembly
1. Identify basic parts of personal computer.
2. Assemble the computer unit based on proper
procedure.
3. Disassemble the computer unit based on proper
procedure.

1. Prepare the system unit and other necessary tools.
2. Turn off the system unit.
3. Observe the OHS procedure.
