These tools may seem harmless, but using unsafe or faulty tools may cause many injuries especially in the beginners. The Following are some of the safety practices related to hand tools. General hazards: 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 a 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 dust. Insulated tools with appropriate ratings must be used for electrical work). 10 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. Always cut a right angle. Never rock from side to side or bend the wire back and forth against the cutting edges. 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: Never use screwdrivers as a pry bar, chisel, and punch stirrer or scraper. Always use a 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. (The blade will retract when pressure as the knife is released. 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. 11 What's More Directions: Identify the following dos and don'ts in using hand tools. Write DO if the statement is correct and DON'T if it's not. 1. Always use a sharp blade. 2. Cut hardened wire only with pliers designed for that purpose. 3. Use screwdrivers as a pry bar, chisel, and punch stirrer or scraper. 4. Throw away screwdrivers with broken or worn handles. 5. Leave a knife unattended with the blade exposed. 6. Keep your free hand away from the line of the cut. 7. Always use a screwdriver tip that properly fits the slot of the screw. 8. Use pliers on a screwdriver for extra leverage. Only use wrench or screwdrivers specifically designed to accept them. 9. Bend or apply side loads to blades by using them to open cans or pay loose objects. 10.Use pliers as a hammer on the handle. Such abuse is likely to result in cracks or breaks. 12 What I Have Learned Directions: Now that you've learned a lot from the very start of this module, let's summarize our it by filling the blanks with an appropriate answer. 1.
