 Lesson
Plan and Prepare for Task
1 to be Undertaken

What I Need to Know

At the end of this module, you should be able to:

1. Determine requirements of task in accordance with required output

2. Select appropriate hardware and software according to task
3. Plan a task to ensure that OHS guidelines and procedures are followed
4. Follow client-specific guidelines and procedures

Planning plays the most important role of achieving a successful task. Your ability to plan
properly will enable you to attain your target or purpose. Many successful entrepreneurs have
realized their success through proper and careful planning. Likewise, aside from planning, you
should also give importance to preparation. Good preparation will boost your confidence
because it means that you are ready to do the task because you have sufficient knowledge
about it.

As a computer system servicing student, you also need to familiarize with the materials
and tools involved in order to really attain the good result of the task given and to avoid lagging
when performing the task to be undertaken.

Let us determine how much you already know about planning and preparing for task to be
undertaken. Take this test.

 What Is It

The following are some factors to be considered when you plan and prepare for the tasks:

1. PLACE. See to it that the

place for doing the task is
conducive to work, well-
ventilated, clean, and well-
lighted. A space provided for
freedom to move is important.
A place chosen will give you
an idea on what task to be
performed.

2. WASTE DISPOSAL. Used wire

or wire strips or other things
that can’t be used anymore
must be disposed in proper
storage bin or container.

3. TOOLS/EQUIPMENT. Tools and

equipment must match with the task to
be done. You should be careful enough
to choose tools and equipment that are
worthy of use. They must be in good
condition so that it can be easily utilized
without damaging the parts.

A tool is a handheld device that aids in accomplishing a task.

3
 Tools range from a traditional metal cutting part of a machine to an element of a
computer program that activates and controls a particular function.

Tasks to be undertaken in proper tool selection

1. How do you select the best tool for the job? First, know and understand in detail the
scope of work to be accomplished. Second, plan for the scope considering the
sequence of tasks.

2. Selecting the best tool for each task requires training in the proper use of the tools,
field experience in their safe use, and manufacturer’s guide for that specific tool.

3. When obtaining the tool, all the associated tooling and consumable parts
recommended by the manufacturer must be included.

In addition, related consumable parts must also be selected and used according to
their manufacturer’s instructions.

4. SAFETY. Always prioritize safety. Remember that accident is not an excusable incident. It
can be avoided. Always remember the motto “Safety first”.

5. PROCEDURE/TASK. Identify what task to perform before identifying materials and tools to
use. The service procedure/task to employ will tell you the corresponding tools and materials
needed. Appropriate tools to use with the task will enhance your ability to provide a competitive
and efficient service.

Crimping

Occupational/ Operational Health and Safety (OHS) is a cross-disciplinary area

concerned with protecting the safety, health and welfare of people engaged in work or
employment.

Knowing OHS is essential to minimize the hazards and risks not only to students,
trainers and other people within the training institution but others who will be affected.

Reasons for occupational safety and standards are:

• Moral – an employee should not have to risk injury at work, nor should others have
associated with the work environment.
• Economic – many governments realize that poor occupational safety and health
performance results in cost to state
• Legal – OHS requirements maybe reinforced in civil law and/or criminal law

SAFETY PROCEDURES(OHS)

1. To prevent electrical shock hazard, disconnect the power cable from the electrical
outlet before relocating the system unit.
2. When adding and removing devices to or from the system unit, ensure that the power
cables for the devices are unplugged before the signal cables are connected. If
possible, disconnect all power cables from the system unit before you add a device.
3. Make sure that the supply voltage meets the required voltage of the power supply
unit.
4. Before installing the Motherboard and adding a device on it, carefully read the entire
manual that came with the package.
5. To avoid short circuits, keep paper clips, screws, and staples away from connectors,
slots, sockets, and circuitry.
6. Avoid dust, humidity, and temperature extremes. Do not place the product in
any area where it may become wet.
7. Always ground or discharge yourself before touching any part of the computer.

5
 8. Do not work alone so that there’s someone who can take care of you in case
of accident or emergency.
9. Be careful with the tools that may cause short circuit.
10. Always pull the cable connector on the handle and not on the cable itself.
11. Wear rubber shoes when standing on the ground or on a concrete floor.
12. Make sure that the pins are properly aligned when connecting a cable
connector.
13. Always power off and unplug the computer before disassembling and
assembling.
14. Take away any liquid such as mineral water or soft drinks near your working
area or near computers.
15. Contingency measures during workplace accidents, fire and other emergencies
are recognized.

SAFETY PRECAUTIONS

1. Do not place any combustible materials near the power outlet.

2. Avoid using power cord with defects such as loose contacts and exposed
conductors.
3. Avoid using connecting wires with exposed conductors.
4. Do all the wiring connection inside the computer system with the power off.
5. Check the proper connections before turning the circuit power on.
6. Remove any jewelry which is conductive.
7. Check your measuring instruments for proper voltage, current, and resistance
setting before making any measurement.
8. Refer to the motherboard manual for its proper jumper setting and connection.

In your workplace or in the laboratory, do you apply any operational health and safety
standards? In what way?
