20. Proper Tool Selection
• 1. Know and understand the scope of labor and plan for
the action to be undertaken in accomplishing any tasks.
• 2. Selecting the simplest tool for every task requires
training within the proper handling of the tools, safety
and maintenance and following the manufacturer’s
manual.
• 3. When obtaining the tools, all the associated tooling and
consumable parts, as recommended by the manufacturer
must be included. Additionally, related consumable parts
must even be selected and used in step with their
manufacturer’s instructions.

21. Environmental Safety and Health for Tools
Once selected, use the tool for the purpose that it had been
designed. For safety measures, follow the Do’s and Don’ts
within the manufacturer’s manual.
• a. Keep all tools in good shape with regular maintenance.
• b. Consider the correct tool for the job.
• c. Examine each tool and do not use damaged or defective
tools.
• d. Operate each tool according to its manufacturer’s
instructions.
• e. Observe appropriate use of the tool and protective
equipment when using.

22. Marking Unsafe or Faulty Tools
Assessments that may be made or tagged after
cautious inspections are the following:
Proper operating condition. Tools and equipment
that are tagged with this assessment are considered
safe to be used. Only tools that experienced intensive
inspection must be tagged with this. These tools
must be visually checked and operationally tested
before releasing to anyone.

23. Recommended for upgrade. This is intended for the
tools and equipment that are still in good operational
condition but are not so outdated. These tools must
be upgraded soon to stick with new standards and
benchmarks. Old tools can still be used occasionally.
Damaged and for repair. For tools and equipment
that are labeled as damaged or for repair must not
ever be put into use. These tools impose a threat to
the user and will delay the completion of works.
Damaged tools must be sent for repair at once.
Marking Unsafe or Faulty Tools

24. For disposal. This pertains to tools and equipment
with worst condition such as broken and is beyond
repair. The tool might also be damaged and buying a
replacement is more beneficial. Tools that are tagged
during this group must be properly thrown away for
them to not become a hazard within the workplace.
Marking Unsafe or Faulty Tools

25. •Personal Protective Equipment (PPE)
Personal Protective Equipment (PPE) refers to a device
or appliance designed to be worn during work or held by
worker for his protection against health and safety
hazards.
•PPE in Computer System Servicing
Aside from goggles, safety shoes, apron, gloves and
facemask, the anti-static wrist strap and anti-static mat
are the most essential equipment to follow according to
its PPE standards.

26. Reporting malfunctions, unplanned or unusual
events to the property custodian
Here are the suggested procedures if there have
been no malfunctions or technical hitches after
the completion of the work requirement.
1. You must bring the request form and return all
the borrowed tools to the property custodian.
2. The return report would need to state that all
returned tools are still in proper operating
condition.

27. 3. After delivering the tools, ensure that the property custodian
waives your accountability form.
In case there have been problems that occurred during the
completion of work requirement that resulted in damaging a tool or
equipment, follow these procedures.
3.1 Report instantly to the property custodian in case are
mishaps or damages to any requested tools, so he could issue a
replacement instantly.
3.2 Request for one more set of tools to use.
3.3 Prepare the tools to be returned, once the work requirement
is finished,
Reporting malfunctions, unplanned or unusual events to the
property custodian

28. 3.4 Be bound to attach an evidence detailing the
events that caused the tool or equipment to be
damaged.
3.5 Have the report received by the laboratory
custodian so proper investigation can start.
3.6 If proven that there was no negligence on the

property custodian

29. Tool and Equipment Maintenance
In choosing good quality tools you must
be wise and practical, but if you take good

longer and return you a good favor. Make
sure that your tools are safely and properly
stored, cleaned, and well maintained to save
you from time, effort, and money as well as
making your business, projects and jobs
easier.

30. Tool and Equipment Maintenance
Preventive maintenance is the key for a
systematic care and protection of tools,
equipment and machines in order to keep
them in a safe, protected, usable condition,
limit downtime and extend productivity
during work. You must always be aware that
maintenance tasks which are potentially
hazardous can result to injury.

31. Tool and Equipment Maintenance
The successful maintenance program is:
• well organized and scheduled;
• controls hazards;
• defines operational procedures; and
• trains key personnel.

32. METHODS IN MAINTAINING HAND TOOLS
Conduct Maintenance Activity
It is necessary for a tool to be well-maintained and
one of the methods in doing this is conducting a
