Manual tools can be categorized based on their use into convenient household tool set, including wrenches, pliers, screwdrivers, tape measures, hammers, sockets, cutting tools,scissors, sets, and auxiliary items like tool carts, among others.
Most people have not received training before using manual tools, which leads to frequent accidents. Statistics show that injuries caused by improper use of manual toolsaccount for 7% to 8% of all accidental injuries. Therefore, it is essential to understand the correct methods of using various common basic tool kit and lightweight power toolsand to pay attention to safety.
Hand Saw
Choose the appropriate saw blade based on the hardness and thickness of the material being worked on. The tightness of the saw blade should be moderate and adjusted according to the feel in hand.
The workpiece to be cut should be clamped securely, with no displacement or vibration during the cutting process. The cutting line should be close to the support point of the workpiece.
Hold the saw straight to prevent skewing. Start the cut smoothly, with the initial cutting angle not exceeding 15 degrees to avoid the saw teeth from getting caught in the workpiece.
When cutting, apply appropriate force with both hands while pushing the saw forward; when pulling the saw back, lift the saw slightly without applying pressure.
When installing or changing to a new saw blade, ensure that the teeth of the blade face forward. After changing the blade mid-cut, saw in the opposite direction instead of continuing along the original cut. When the workpiece is about to be cut off, hold it with your hand to prevent it from falling and causing injury.
Wrench
Select the appropriate size of wrench based on the nature of the work.
When using an auto professional tool set, apply force towards the fixed jaw, never towards the adjustable jaw.
Do not continue using a wrench if the opening is worn or if it slips during use to avoid injury from slipping.
Do not use a wrench as a hammer.
Do not increase the torque of the wrench by adding a pipe to the handle.
Screwdriver
Match the screwdriver to the size and shape of the screw head groove.
Do not use a hammer to strike the screwdriver handle, and replace it immediately if it is damaged.
Do not use a screwdriver as a chisel or lever.
Use an electrician's screwdriver to test currents, not a regular screwdriver for high-voltage electricity.
Do not grind the cutting edge of the screwdriver to avoid damaging the hardened surface.
Do not carry a screwdriver in your clothes or pants pocket to avoid injury from collision or falling.
Pliers
Pliers are only for tightening, embedding, and removing various pins, nails, and for cutting or twisting various wires.
Pliers should not be used to tighten or knock on bolts or nuts.
Do not hit the handle of the pliers or extend the handle to increase the clamping or cutting force.
Hand Drill
Use a wrench of the appropriate size to tighten or loosen the drill bit.
Hold the drill firmly before turning on the switch.
Turn off the power and put down the drill before not using it or changing the drill bit.
Unmount the drill bit when finishing work.
Apply moderate pressure on the drill bit; too much force may break it or reduce its speed, too little may cause it to wear out. Be gentle when about to drill through to ensure smooth penetration.
Secure small workpieces with a clamp when drilling, never hold them by hand.
Do not wear loose clothing, ties, scarves, or gloves when using a drill, and tie back long hair.
Soldering Iron
Keep the tip of the soldering iron clean and free of debris.
Do not hit it, as this may cause the insulating casing to crack and lead to electrical leakage.
Use a soldering iron of 30 to 40 watts for transistor components.
Place the soldering iron on a stand or insulator when not in use.
Be aware of the high temperature of the soldering iron tip to avoid burns or causing fires near flammable materials.
Prevention of Manual Tool Injuries
Direct causes of injuries from manual tools include impact or collision, cutting, splashing, and electric shock from power tools.
Reasons for manual tool injuries include using inappropriate tools, failing to maintain them, not checking them before use, incorrect usage methods, not wearing appropriate personal protective equipment, and improper tool storage.
Principles for safe use of manual tools include selecting the right tools for the job, maintaining tools in good condition, choosing high-quality tools, checking tools before use, using the correct methods, storing tools safely, wearing appropriate protective gear, and using standard or specified tools.
