(2) Dangers of pressure machinery There are punching machines, shearing machines, crimping machines, pulverizers, roller compactors, embossing machines, and presses. The pressure machinery has a certain pressure site, and the pressure site is the most dangerous. Since most of these devices are manually operated, the operators are prone to fatigue and boredom, and human errors occur. For example, raw materials are not allowed to fly, molds are displaced, or the hand enters dangerous areas, and personal injury accidents can easily occur.
(3) Dangers of machine tools Machine tools are high-speed rotating cutting machines and are very dangerous.
1. The rotating parts, such as drill chucks and lathes that rotate on the lathe, etc., once tangled with people's clothes, cuffs, long hair, towels around the neck, gloves on the hands, etc.
2. The operator collides with the machine tool. For example, due to improper operation method, excessive force, and improper use of tool specifications, the operator may hit the machine tool;
3. If the operator's station is not properly positioned, it may be impacted by mechanical moving parts. For example, standing on the surface grinding machine or the moving parts of the planer, it may be hit by a surface grinding machine work bench or a bull planer ram. .
4, the tool hurts, such as high-speed rotary cutter to cut off the finger or even the arm.
5, the splash of hot red steel shavings, cuttings scratches and scald the human body, splashed abrasives and broken chips injure human eyes.
6, the work site environment is not good, such as inadequate lighting, ground slippage, unreasonable machine tool layout, narrow channels and unreasonable parts, semi-finished products piled up, etc., may cause the operator to slip or fall.
7, the erosion of the skin of the coolant, the harm to the human body and other noise.

What are the general mechanical equipment hazards?
(1) Dangers of transmissions Mechanical transmissions are generally classified into gear transmissions, chain drives, and belt drives. Because the components do not meet the requirements, if the mechanical design is unreasonable, the transmission part and the protruding rotating part are exposed and there is no protection, and the handle and clothes may be twisted into it to cause injury. In the chain drive and the belt drive, the pulley is easy to get into the limb of the tool or the person; when the chain and the belt break, the joint easily catches the human body, and the belt flies up and hurts the person. For reasons such as friction and belt speed in the transmission process, it is also easy for the transmission belt to generate static electricity, generate static electricity sparks, and cause fire and explosion.
