works. Plumb Bob is used to check the vertical
alignment of any members or pipes.

16. Plumb Bob is the name of this tool. Thank you,
_____. I believe you know our most common
plumbing tools and equipment. Now, after
identifying our tools, let’s study how we can store
and maintain them properly.
We have here five (5) tips on how store and
maintain our tools and equipment. The first tip is to
Store Tools in the Toolbox. You should have big
toolbox so that you can easily find your tools when
doing a project. When storing the toolbox and your
tools, always keep them in a room-temperature
environment with low humidity. No direct sunlight
should land on the equipment.
Why do we need to be careful about humidity?
That is correct. Thank you, ______. For the second
tip, Inspect Your Tools Thoroughly. During your
inspections, you’ll be looking to make sure that
there are no outwardly visible issues. This can
include chips and cracks or equipment that is
broken. If there are any problems, you’ll need to fix
or repair them.
Why are regular inspections important for our
tools?
That is the main reason why we inspect our tools.
Good thinking, ______. Thank you.
For our third tip, we have to Clean Our Equipment
Regularly. Ideally, you should clean your
equipment after every job. This may not be
possible during busier days, but you can still wipe
down your equipment between jobs.
Humidity can cause rust to our tools, making them
blunt and broken, sir.
Sir, regular inspections keep you aware of the state
of your equipment. You also don’t have to worry
about your tools falling on you during work.

17. How do we keep our hand and power tools in good
shape?
That is correct, ______. Thank you for that. For our
fourth tip, we have Care for Your Power Tools.
Power tools can be battery powered. In these cases,
you need to be careful about how you store them.
If you don’t need to use a power tool for an
extended period of time, then remove the batteries
until you need the tool.
In power tools, what else do we check before using
them?
Precisely! Thank you for that, _____. For our last
tip, you need to Care for your Hand Tools.
Maintaining your hand tools and sharpening the
blades on a regular basis will help them last longer.
Those are the tips we need to remember when
storing our tools and equipment. Doing these tips
will ensure your tools and equipment will be
functional and can be used for longer period of
time.
Before storing your tools, you also need to
remember five (5) methods in identifying
functional to non-functional tools. Can someone
give me the first one?
Hand and power tools will need a different
cleaning regimen as well. These need to be
lubricated regularly to ensure that they work well,
sir.
You should also keep an eye on the power tools to
see if the cords are fraying. Fraying or exposed
wires can cause electrocution and fire related
accidents.

18. That is right. Thank you, ______. This is the
physical appearance of the tools. Whether it has
broken handle or chipped blade. What is our
second method?
That is correct, ______. That means there might be
loose screws or there are debris that went inside
your tool or equipment. For our third method, we
have Performance. What do we mean about this
method?
Precisely! This makes your work easier and safer.
Now, can someone give us the fourth method on
checking which tools are functional and non-
functional?
That is correct. Thank you, _____. When these
tools malfunction, the worker may also be
electrocuted and may cause danger. Now for the
last method, we have Person’s Involved. This
The first one is Visual Inspection. It refers to the
visual observation of an expert on the appearance
of the tools and equipment.
The second method is Functionality. Vibration or
extra noise from the operation means problems on
parts and accessories started to develop.
When there is something wrong with the
performance of either hand tools or equipment,
they need an immediate repair or maintenance, sir.
Sir, the next one is Power Supply. This is
applicable to electrically operated equipment.
Failure to meet standard power supply may cause
harm to the worker.

19. refers to the technical person who has the
knowledge and skills about the technology. This
means yourself and the understanding you have
towards your tools.
In our discussion, I truly see that you understand
our lesson and you study our module in advanced.
Good job, class.
D. ABSTRACTION/GENERALIZATION
