Identify different kind of hand tools. B. Check appropriate hand tools for proper operation and safety. Ø Topic:Using Hand Tools Let Us Discover In engaging yourself in any activity on your computer you should know first the different kinds and appropriate tools in fixing or doing something on it. In computer application, the usage of proper hand tools and equipment is very essential. The following hand tools are usually being prepared and used especially in fixing or troubleshooting a computer equipment or devices. 1. Flat Screw Driver- a tool used to 2.

These tools may seem harmless, but using malfunctioning or faulty tools may cause injuries or accidents especially among beginners. The two most common hazards associated with the use of Hand Tools are misuse and improper maintenance. Misuse occurs when a hand tool is used for something other than its intended purpose. (An example would be using screwdriver as a chisel. This may cause the tip to break and strike someone). Improper maintenance allows hand tools to deteriorate into an unsafe condition. (Example would include cracked wooden handles that allow the tool head to fly off or mushroomed heads that can shatter upon impact. Specially designed tools may be needed in hazardous environments. (Always use non-sparking tools in the presence of flammable vapors and dusts. Insulated tools with appropriate ratings must be used for electrical work). The following are some of the best practices in using safe tools: Pliers: Never use pliers as a hammer on the handle. Such abuse is likely to result in cracks or breaks. Cut hardened wire only with pliers designed for that purpose. Do not increase the handle length of pliers to gain more leverage. Use a larger pair of pliers or bolt cutters. Do not substitute pliers for a wrench when turning bolts and nuts. Pliers cannot grip these items properly and will slip. Screwdrivers: Always use screwdriver tip that properly fits the slot of the screw. Keep away screwdrivers with broken or worn handles. Use magnetic or screw-holding screwdrivers to start fasteners in tight areas. Never use pliers on a screwdriver for extra leverage. Only use wrench or screwdrivers specifically designed to accept them. Utility Knives/ Blades: Always use a sharp blade. Dull blades require more force and thus are more likely to slip. Replace the blade when it starts to “tear” instead of cut. Never leave a knife unattended with the blade exposed. Consider using a self- retracted knife with a spring-loaded black. Keep your free hand away from the line of the cut. Don’t bend or apply side loads to blades by using them to open cans or pay loose objects. Blades are brittle and can snap easily. 3 GSC-CID-LRMS-ESSLM, v.r. 03.00, Effective June 14, 2021  Let Us Try Directions: Identify the following DOs and DON’Ts in using hand tools.
