Here are some of the dangers and safety measures for using handheld power tools:
Pistol drill:
Unsafe factor (dangerous point):
First, electric shock:
1. The power supply voltage must match the voltage specified by the tool.
2. The inner, outer casing and wires must be inspected for good insulation before use. No leakage is allowed.
3. The correct grounding device must be used before use, and the plug cannot be inserted in the wrong position.
4. Before use, install a qualified leakage protector with a rated operating current of no more than 15 mA, an operating time of no more than 0.1 sec, or a rated leakage current of no more than 30 mA and an operating time of no more than 0.1 sec.
5. When working in a metal container, special personnel must be provided to monitor the outside without interruption. The leakage protector, power connector and control box should be placed outside the container. The staff should be covered with insulation board at the foot of the worker. Use power tools in particularly humid places. Appropriate overalls, insulated gloves and insulated shoes must be worn.
Second, mechanical injury:
1. Before use, you must confirm that the drill is a qualified drill, labeled or certified.
2. Before use, it must be checked that the nuts of the mechanical transmission parts are firmly fastened and qualified before use.
3. Before turning on the power, you must carefully check that the switch of the tool you are using should be in the off position before you can turn on the power.
4. When replacing the drill bit, the power plug must be unplugged before the replacement work can be carried out. Check the drill bit without cracks and no defects on the surface.
5. The workpiece must be securely fixed on the workbench during use. The drill bit must also be clamped. The drill bit must not collide with the body and the workpiece.
6. Do not force the drill bit into contact with the object during work. Gently touch the appropriate entry and keep your hand away from the rotating parts.
7. Wear protective goggles to wear appropriate work clothes when working. People with long hair must wear a hat, clean the work place, and do not have anything to be caught by the drill bit. Both hands must be clenched and carefully guarded.
8. When working, the body must maintain proper posture and must stand firm. Do not reach out and take tools and work.
9. The tool used must be placed in a safe and secure position after the switch has been completely stopped, and then the plug is unplugged.
10. It is strictly forbidden to use one hand to work on the workpiece with a pistol drill.
11. There must be more than 2 people working, and there must be someone to carry out continuous monitoring.
Electric wrench:
Unsafe factor (dangerous point)
First, electric shock:
1. The power supply voltage must match the voltage specified by the electric wrench.
2. The inner, outer casing and wires must be inspected for good insulation before use. No leakage is allowed.
3. The correct grounding device must be used before use, and the plug cannot be inserted in the wrong position.
4. Before use, install a qualified leakage protector with a rated operating current of no more than 15 mA, an operating time of no more than 0.1 sec, or a rated leakage current of no more than 30 mA and an operating time of no more than 0.1 sec.
5. When working in a metal container, special personnel must be provided to monitor the outside without interruption. The leakage protector, power connector and control box should be placed outside the container. The staff should be covered with insulation board at the foot of the worker. Use power tools in particularly humid places. Appropriate overalls, insulated gloves and insulated shoes must be worn.
Second, mechanical injury:
1. Before use, you must confirm that the wrench is a qualified wrench, labeled or certified.
2. Before use, it must be checked that the nuts of the mechanical transmission parts are firmly fastened and can only be used after passing the test.
3. The power plug must be unplugged before replacing the wrench to replace it.
4. The wrench must be securely fixed during use, and the hands must be firmly held (in special cases, the wrench can be lifted and fixed) to prevent the danger of the tool being detached.
5. Before starting the machine, you must determine the direction of rotation, and then confirm that there is no abnormality before working. The working force should be even, and the force is too strong.
6. Work must be more than 2 people, the special person operates the operation box to control the work and stop of the electric wrench.
7. When using, the wrench should be supported. Avoid touching the wrench to prevent the cable from falling off.
8. The body must maintain a proper correct posture during work and must stand firm so that the tool axis is aligned with the thread axis and held firmly.
9. Before turning on the power, you must carefully check that the switch of the tool you are using should be in the off position before you can turn on the power.
10. The tool used must be placed in a safe and secure position after the switch has been completely stopped, and then the plug is unplugged.
11. When working vertically, two or more people must hold the tool and the third person should operate.
12. There must be more than 2 people working at the time, and special personnel should be on uninterrupted supervision.
