What is It
I. Using and Maintaining Hand Tools (UHT) Proper Tool Selection A tool is
a handheld device that aids in accomplishing a task. 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.
Safe Use of Tools
Once selected, use the tool for the purpose for which it was designed. Not all
tools come with detailed instructions, but some do spell out the safety “Do’s

12. and Don’ts” for your safety. If there are set-up/use options, operator judgment
must always be based on what is the safest way to use the tool.
Environmental Safety and Health Program requires the following: 1.
All tools should be kept in good condition with regular maintenance. 2.
The right tool should be used for the job.
3. Each tool should be examined before use and damaged or defective
tools should NOT to be used.
4. Tools should be operated according to the manufacturer’s instructions.
5. The right protective equipment for the tool and activity should be used.
FOUR CATEGORIES OF COMPUTER HARDWARE SERVICING TOOLS
1. Electro-Static Discharge (ESD) Tools
🞆 Static electricity is easily generated by friction on carpets, tile flooring,
clothing, hair, fabric, etc… The friction of moving air alone will charge
suspended particles and cause the buildup of static electrical charges
on people and objects in the environment. Grounded antistatic work
mats used with antistatic wrist straps provide the most basic means for
the controlled discharge of electrostatic electricity. Examples of ESD
