The hidden dangers of accidents are summarized into 21 categories:

Fire, explosion, poisoning and suffocation, water damage, collapse, landslide, leakage, corrosion, electric shock, fall, mechanical damage, coal and gas outburst, road facility damage, road vehicle damage, railway facility damage, railway vehicle damage, water transportation damage, Port and dock injury, air transportation injury, airport injury, other hidden dangers, etc.

The main countermeasures and measures for the rectification of hidden danger

1. Implement mechanized and automated production
Mechanized and automated production is not only an important means of developing production, but also a fundamental way to achieve intrinsic safety. Mechanization can reduce labor intensity, and automation can reduce the risk of personal injury.

2. Set up safety devices
Safety devices include protective devices, safety devices, and warning devices.

3. Enhance mechanical strength
Mechanical equipment, devices and their main components must have the necessary mechanical strength and safety factor.

4. Ensure electrical safety and reliability
Electrical safety countermeasures usually include anti-electric shock, anti-electrical fire and explosion, and anti-static. The basic conditions to ensure electrical safety include: safety certification, backup power supply, anti-shock, electrical fire and explosion protection, and anti-static measures.

5. Maintain and overhaul machinery and equipment as required
Machinery and equipment are the main tools of production. During operation, some parts will inevitably wear out or be damaged prematurely, which may even cause accidents on the equipment. As a result, not only production stops, but also operators may be injured.

Therefore, in order to keep machinery and equipment in good condition and prevent equipment accidents and personal injury accidents, frequent maintenance and planned overhaul must be carried out.

6. Maintain a reasonable layout of the workplace
The workplace is the area where workers use machinery, equipment, tools and other auxiliary equipment to process raw materials and semi-finished products. A sound organization and reasonable layout can not only promote production, but also a necessary condition for ensuring safety.

The messy stacking of metal scraps, lubricating oil, emulsion, rough, semi-finished products scattered in the workplace, and uneven ground can all lead to accidents.

7. Equipped with personal protective equipment
It is necessary to provide personal protective equipment with corresponding protective functions as supplementary countermeasures according to the hazards, harmful factors and work types.
