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 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 Tools:
5
Antistatic wrist strap – used to prevent ESD damage to computer equipment.
Antistatic mat – used to stand on or place hardware on to prevent static electricity from building up.
2. Hand Tools is a device for performing work on a material or a physical system using hands only. The hand tools can be manually used by employing force, or electrically powered, using an electrical current. Examples of Hand Tools: Flat-head screwdriver – used to loosen or tighten slotted screws.
Philips-head screwdriver – used to loosen or tighten crosshead screws.
Torx screwdriver - used to loosen or tighten screws that have a star-like depression on the top, a feature that is mainly found on a laptop.
Hex driver – sometimes called a nut driver, is used to tighten nuts in the same way that a screwdriver tightens screws.
6
Needle-nose plier – used to hold small parts.
Wire cutter – used to strip and cut wires.
Tweezers – used to manipulate small parts.
Part retriever – used to retrieve parts from a location that are too small for your hand to fit.
Flashlight – used to light up areas that you cannot see well.
3. Cleaning Tools Having the appropriate cleaning tools is essential when maintaining or repairing computers. Using these tools ensures that computer components are not damaged during cleaning. Example:
Lint-free cloth – used to clean different computer components without scratching or leaving debris.
7
Compressed air – used to blow away dust and debris from different computer parts without touching the components.
Cable ties – used to bundle cables neatly inside and outside of a computer.
Parts organizer – used to hold screw, jumpers, fasteners and other small parts and prevents them from mixing together.
4. Diagnostic Tools Computers are easier to use and more dependable with each new generation of hardware and operating system update, but that doesn't mean they're problem-free. Here are the most popular tools for diagnosing your computer problems: Multimeter – used to test the integrity of circuits and the quality of electricity in computer components.
Loopback Adapter – used to test the functionality of computer ports.
