3. www.facebook.com/itsmeismael INTRODUCTION   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.

4. www.facebook.com/itsmeismael Proper Tool Selection Know and understand in detail the usage of the work to be accomplished. 2. Plan for the scope taking into account of the sequence of tasks.  

5. www.facebook.com/itsmeismael 3. Select the best tool for each task. This may require training in proper use of the tools, field experience in their safe use and following manufacturer’s guide and instructions for that specific tool. 4. Obtain the tool along with its associated tools and consumable parts as recommended by the manufacturer. Remember to select and use the consumable parts according to their manufacturer’s instruction.

6. www.facebook.com/itsmeismael Safe Use of Hand Tools Misuse of hand tools may lead to injuries within ourselves and/or people working around us. Also, incorrect use of hand tools may damage the tool itself that causes the tool to fail. Thus, hand tools must be safely used.

7. www.facebook.com/itsmeismael   Guidelines for Hand Tools Safely   Use the right tool for the job As tools are designed for specific needs, the first step in safe hand tool is using the correct tool for the correct job. This is the reason why there are screwdrivers with various lengths and tip styles and pliers with different head shapes. Improper use of a tool is a step in the wrong direction. Inappropriate use of hand tool causes injury, tool damage and even equipment damage.

8. www.facebook.com/itsmeismael Use insulated tools when needed. Insulated tools are designed to reduce the chance of injury if the tool should come in contact with an energized source. As we never know when a situation will arise where insulated tools are required, we need to have some insulated tools in our collections. We must frequently inspect insulated tools for any wear or cracking of the insulation. Keeping tools clean, dry and free from surface contaminants is important as not to compromise insulating properties. It is best not to use tools that have been broken by cutting, worn or burned out. Make note that tools with plastic clipped or slip-on-plastic handles are not insulated. They are only featured for comfort. Likewise, wrapping a tool with elastic tape does not promote insulation.

9. www.facebook.com/itsmeismael Follow general safety and maintenance practices. Improper use of tools is not only dangerous but also shows a lack of understanding of tool safety, and disrespect for those around you, thus, following safety and maintenance practice is a must. Wearing an approved eye protection is one of the safety practices when using a hand tool. Through it, we can protect our eyes from serious injuries.

10. www.facebook.com/itsmeismael Another safety practice is keeping cutting tools like knives, bolts, cutters, and pliers sharp, lubricated and in good repair. Cutting wire, bolts and similar materials must always be made at a 90-degree angle to avoid clipping the edges of the knives. Pliers must not also be rocked when attempting to cut materials. This puts tremendous side pressure on cutting surface that can result to tool failure.

11. www.facebook.com/itsmeismael Use well-designed, high quality tools. For safer and easier job, investing in high quality tools is advised. If you are using pliers, take note of the qualities of high-quality pliers. For jobs requiring extra leverage, use high-leverage pliers. This plier gives more cutting and gripping power than standard pliers. It is also best in jobs with repetitive cuts or twisting numerous wire pairs. Pliers with hot riveting at the joint ensure smooth movement across the full active range of pliers. This reduces handle wobble for positive cut. For heavy-duty cutting, use side-cutting and diagonal-cutting pliers.

12. www.facebook.com/itsmeismael In using knives, choose sharp cutting knives and tempered handles for better cutting result. Further, for other tools not mentioned, you must look for well-designed tools with a contoured thumb area for a firmer grip or color-coded handles for easy tool identification. Using well-designed and high-quality tools save time and give professional results to you. Most importantly they help you do your job safely.

13. www.facebook.com/itsmeismael Other Basic Safety Rules for Hand Tools Keep your hand free from oil and grease. Handle sharp-edged and pointed tool with care by your side with the points and heavy ends down. Secure all small work and short work with a vise or clamp. Carry tools with its storage box for protection; never put them in your pocket. Use tools in good condition not those that are loose or cracked. Make sure your tools are all with handles. Clean the tools after using and return them to proper storage place.

16. www.facebook.com/itsmeismael Preparing for the task to be undertaken includes 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 taking into account the sequence of tasks.  

17. www.facebook.com/itsmeismael 2. Selecting the best tool for each task requires training in the proper use of the tools, field experience in their safe use, and following the manufacturer’s guidance and instructions for that specific tool. 3. When obtaining the tool all the associated tooling and consumable parts, as recommended by the manufacturer, must be included. In addition, related consumable parts must also be selected and used according to their manufacturer’s instructions.  

18. www.facebook.com/itsmeismael 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 there are those that 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.

19. www.facebook.com/itsmeismael Environmental Safety and Health Program requires the following: All tools be kept in good condition with regular maintenance The right tool be used for the job Each tool be examined before use AND damaged or defective tools NOT to be used Tools be operated according to manufacturer’s instructions The right protective equipment for the tool and activity be used

20. www.facebook.com/itsmeismael HARDWARE TOOLS To complete hardware repairs, it is important to have a toolkit that should contain all of the necessary tools. As you gain experience, you will learn which tools to have available for different types of jobs. Hardware tools are grouped into these four categories: Electro-Static Discharge (ESD) tools Hand tools Cleaning tools Diagnostic tools

21. www.facebook.com/itsmeismael Electro-Static Discharge (ESD) Tools Static electricity is easily generated by friction on carpets, tile flooring, clothing, hair, fabric, and 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.  

22. www.facebook.com/itsmeismael Examples of ESD Tools Anti-static wrist strap – used to prevent ESD damage to computer equipment.   Anti-static mat – used to stand on or place hardware on to prevent static electricity from building up.

23. www.facebook.com/itsmeismael HAND TOOLS A hand tool is a device for performing work on a material or a physical system using only hands. The hand tools can be manually used employing force, or electrically powered, using 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.

24. www.facebook.com/itsmeismael Torx screwdriver - used to loosen or tighten screws that have a star-like depression on the top, a feature that is mainly found on laptop. Hex driver – sometimes called a nut driver, is used to tighten nuts in the same way that a screwdriver tightens screws. Needle-nose plier – used to hold small parts. Wire cutter – used to strip and cut wires

25. www.facebook.com/itsmeismael Part retriever – used to retrieve parts from location that are to small for your hand to fit. Tweezers – used to manipulate small parts. Wire Stripper – A tool designed to remove the protective covering (jacket) off of a cable to expose the inner wires. Because different wires come in different shapes, there are dozens of different wire strippers available. In the picture is an example of a wire stripper that strips cables when placed in-between the blade and the holder and spun around the cable until the cable jacket can be pulled off.

26. www.facebook.com/itsmeismael Crimping tools - is a device used to conjoin two pieces of metal by deforming one or both of them in a way that causes them to hold each other. The result of the tool's work is called a crimp. A good example of crimping is the process of affixing a connector to the end of a cable. For instance, network cables and phone cables are created using a crimping tool (shown below) to join the RJ-45 and RJ-11 connectors to the both ends of either phone or CAT5 cable. Flashlight – used to light up areas that you cannot see well.

27. www.facebook.com/itsmeismael 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. Examples: Lint-free cloth – used to clean different computer components without scratching or leaving debris.

28. www.facebook.com/itsmeismael 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 getting mixed together.

29. www.facebook.com/itsmeismael 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's the most popular tools for diagnosing your computer problems: Network Cable Tester- A cable tester is a device that is used to test the strength and connectivity of a particular type of cable or other wired assemblies. There are a number of different types of cable testers, each able to test a specific type of cable or wire (some may be able to test different types of cables or wires). A cable tester can test whether a cable or wire is set up properly, connected correctly, and the communication strength between the source and destination. Loopback Adapter – used to test the functionality of computer ports. Multimeter – used to test the integrity of circuits and the quality of electricity in computer components.
