Anti-static mat c. compressed air b. Hex driver Wire cutter What Do You Need To Know? 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. 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 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. 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.

- 21. USE AND MAINTAIN HAND TOOLS, COMPUTER EQUIPMENT AND ELECTRONIC SYSTEMS (MTCS) Page 21 K-12 Creative Technology Hand tools and computer equipment are sometimes used inappropriately that results to tools being dirty and loosely connected or even damaged. Before using any tools or equipment, it should be inspected properly to ensure that they are operational and safe. One basic thing to remember to keep hand tools, computer equipment and electronic systems are clean is to make sure that the workplace is properly organized. Procedures in cleaning, tightening, and simple repair of hand tools, computer equipment and electronic systems are as follows: 1. Cleaning the tools after use is highly recommended. http://ndcdela-on.blogspot.com/2017/01/safety-procedures-in-using-hand-tools.html 2. All tools and equipment must be placed in a clean and dry place. 3. The work area must always be kept neat and tidy. The possibility of harm and injuries is greatly increased by an unsafe workplace. One must always be aware of the hazards that are present in the work area. The space available in the workplace also influences the efficiency and accuracy of using a hand tool. Working in a tight space may require to use a different set of tools that would fit in the limited area. 4. Lubricants must also be applied after tightening to reduce friction. Lubricant’s function on computer equipment are to reduce friction, prevent wear, protect the equipment from corrosion, controls temperature and provides fluid seal. 5. Before cleaning any tool, be sure to wear the proper personal protective equipment(PPE) such as gloves, mask and googles. PPE are usually worn when cleaning tools since most of the cleaning agents and solutions are harmful to the human body.

Definition of terms What Do You Already Know? Let us determine how much you already know about hand tools, computer equipment and electronic systems. What Do You Need To Know? The proper use of tools, computer equipment and electronic system increases efficiency and occupational safety in a shop. With proper knowledge and skills in using such tools is needed in order to operate and use them effectively. But sometimes problems and malfunctions may arise while using these tools. These malfunctions can be minimized by exercising careful usage of the tools. Malfunctions and unusual event may not be totally eliminated but it can be minimized.

- 24. USE AND MAINTAIN HAND TOOLS, COMPUTER EQUIPMENT AND ELECTRONIC SYSTEMS (MTCS) Page 24 K-12 Creative Technology Listed below are the common malfunctions and unplanned events when using the different tools in completing a job requirement: When using a driving tool, screws may slip the tip of the screw driver. This happens when the screw driver is not properly aligned with drive of the screw’s head. This can be minimized by making sure that the tip of the screw driver is well secured in the drive of the screw’s head. Using a screw driver with a magnetized tip can also help minimize this type of malfunction. Small objects tend to fall down when being held by a gripping tool like pliers. This usually happens when the jaws of the pliers are blunt. Thus making it hard to hold on things. This can be prevented by making sure that gripping tools have well maintained jaws that can grasp objects properly. The use of striking tools also imposes a great threat if there will be a malfunction. Common hazards are heads separating away from the handle of a striking tool must be tightly attached to its head. Mishaps in using cutting tools is also dangerous. Malfunctions may arise from slippage of the material to be cut. This may also happen if a cutting tool is not sharp enough. These unplanned events will cause laceration and wounds to the user. To avoid this, cutting tools must always be kept sharp. Power tools also impose danger during mishaps. Common problems are electrical short circuiting or mechanical problems. Malfunctioning power tools may cause electrocution and even decapitation of the limbs. These accidents can be avoided by making sure that all power tools are well maintained and are in fit operating condition. Diagnostic tools may not impose a threat to the well-being of a worker but inaccurate reading may compromise the completion of a job requirement. Inaccurate reading may occur if a diagnostic tool is not properly calibrated. To avoid this, a regular calibration to all diagnostic tools must be done. REMEMBER: There is certainly no absolute way to avoid any unforeseen malfunctions. The only way to minimize them is to have the appropriate knowledge in using the different tools. Proper inspection and assessment of tools must also be practiced to ensure the safety of the student and the accurate completion of a job requirement. Having a first aid kit in the work area is also necessary so that quick response and cure can be applied in case of any injuries.
