What are the four security defenses?

Four safety precautions: fire prevention, theft prevention, freezing prevention, and gas poisoning prevention.

1. Anti-freeze

The temperature is low in winter, and sometimes extremely cold weather occurs. Operators wear thick clothes and are prone to falls and bruises; equipment, pipes, and instruments are prone to damage. Freezing and condensation occurs, affecting normal production.

2. Anti-slip

There are many festivals such as the Spring Festival, Lantern Festival and so on. People set off fireworks and firecrackers, which also brings great hidden dangers to the safety production of surrounding enterprises.

4. Prevent poisoning

In winter, the atmospheric pressure is in a cold and high-pressure state, and toxic and harmful gases are easy to accumulate in large quantities, causing organic solvents, acute and chronic occupational poisoning and other hazards.

Measures

(1) Preventive measures. This is the most basic and important measure.

(2) Restrictive measures. That is, in the event of a fire or explosion accident. Measures to limit its spread and reduce its losses. Such as installing fire-retardant and pressure-relief equipment, setting up firewalls, explosion-proof walls, etc.

(3) Fire-fighting measures. Equipped with necessary fire-fighting measures, if a fire accidentally breaks out, it can be extinguished in time. Especially if the fire can be extinguished in its early stages, a major fire or explosion can be avoided. Broadly speaking, this is also part of the fire and explosion prevention measures

(4) Evacuation measures. Take necessary measures in advance, such as setting up safety doors or evacuation stairs, evacuation passages, etc. on buildings, aircraft, and vehicles. When a major fire occurs, people or important materials can be quickly evacuated to a safe area to reduce losses.
