What are the four defenses in winter? How to prevent it

Four prevention in winter means that in chemical production, the key points of safety production in winter should be equipment anti-freezing, fire prevention in production area, personnel anti-skid and poisoning prevention. Keywords antifreeze, fire prevention in production area, personnel anti-skid,

To prevent freezing

1. In winter, it is necessary to specify the on-site handover and inspection during the production shift.

2, containers, electrical appliances, equipment before starting to carry out safety inspection before use.

3, strong wind, rain, snow and other bad weather conditions, up and down the stairs, high-rise.

4. Sprinkle water to prevent people from slipping and freezing in the operation area.

fire prevention

1, illegal use of heating appliances in the workplace is strictly prohibited.

2. It is strictly prohibited to work in flammable areas such as cables, belts, oils and combustible gases.

3. It is forbidden to smoke, light a fire and keep warm in areas with inflammable, explosive and dangerous goods.

4. In winter, it is necessary to make clear the on-site handover and inspection during the production shift.

be non-slip

1. Winter is the season with frequent traffic accidents. People should obey the traffic rules on their way to and from work, and speeding is strictly prohibited.

2. Prevent all kinds of traffic accidents. ?

3, all kinds of dangerous operations, must be carried out in strict accordance with the dangerous operation examination and approval system.

4, do a good job of equipment antifreeze inspection in the operation area, for personnel, equipment, rain and snow weather, for the top of the library, electrostatic precipitator, coal mill electrostatic precipitator, kiln to prevent electric shock, equipment maintenance must strictly implement the safety regulations of stopping power transmission. ?

5, high equipment parts damaged, shift to strengthen the daily inspection, fastening, rain and snow weather to strengthen the inspection of open-air equipment, focusing on strengthening the inspection of the discharge port.

Poisoning prevention

Asphyxiation can be used more accurately here. Although the word is not very eye-catching, it also contains the meaning of warning. In winter, not only our field maintenance personnel are afraid of freezing, but also our instruments and some equipment. In some cold areas, the doors and windows of factories are closed in winter, and some still hang heavy curtains. Such occasions are very dangerous. After entering such an occasion, it is necessary to prevent hypoxia.

Extended data

In coal mining enterprises, it refers to cold prevention, antifreeze, fire prevention and poisoning prevention.

In the power industry, it refers to fire prevention, explosion prevention, cold prevention, pollution prevention and small animals prevention.

In building construction, it generally refers to fire prevention, electric shock prevention, poisoning prevention and collapse prevention.
