When a hazardous chemical accident is discovered, it should be evacuated in the direction

b. Because there may be toxic gases in the chemicals that may be dispersed with the wind, of course, evacuate in the upwind direction.

According to the provisions of the Regulations on the Safety Management of Hazardous Chemicals, in the event of a hazardous chemical accident, the main person in charge of the accident unit shall immediately organize rescue in accordance with the emergency plan for hazardous chemicals of the unit, and.

Report to the local production safety supervision and management department and the competent departments of environmental protection, public security and health; In the event of an accident involving hazardous chemicals in the process of road or water transportation, the driver, crew or escort.

Personnel shall also report to the competent department of transportation at the place where the accident occurred. In the event of a hazardous chemical accident, the local people concerned shall immediately organize the supervision and management of production safety, environmental protection, public security and health.

Health, transportation and other relevant departments shall organize and implement rescue in accordance with the emergency plan for hazardous chemical accidents in the region, and shall not delay or pass the buck. So choose A. The people are common.

If the place where the accident occurred and the unit where the accident occurred are not in the same administrative area at or above the county level, the people at the place where the accident occurred shall be responsible for the investigation, and the unit where the accident occurred.

The local people** should send people to participate.

Avoid toxic gases volatilizing into the air and causing poisoning. You also need to run high to avoid the accumulation of liquid chemicals in low places. According to the toxicity of the accident substance and the demarcated danger area, the corresponding protection level is determined, and the corresponding protective equipment is equipped according to the standard according to the protection level.

Basic procedures for on-site emergency treatment of chemical accidents:

1. Establish a warning area After the accident occurs, the warning area should be established according to the situation of chemical leakage and diffusion or the scope involved in flame heat radiation, and traffic control should be implemented on the main road leading to the accident site.

The following should be noted when establishing a warning area:

1) Warning signs should be set up at the boundary of the warning area, and there should be a special person to guard it;

2) Except for firefighting, emergency response personnel and personnel who must stick to their posts, other personnel are prohibited from entering the warning area;

3) When the spilled chemicals are flammable, fires should be strictly prohibited in the area.

2. Emergency evacuation: Quickly evacuate the personnel in the warning area and the polluted area who are not related to the emergency treatment of the accident to reduce unnecessary personnel. Attention should be paid in the event of an emergency evacuation:

1) If the accident substance is toxic, it is necessary to wear personal protective equipment or adopt simple and effective protective measures, and have corresponding guardianship measures;

2) Shift to the upwind direction, clearly guide and escort evacuees to the safety zone, and set up sentinel posts on the evacuation or evacuation route to indicate the direction;

3) Do not stay in low-lying places;

4) Find out if anyone is left in the contaminated area or the fire area.

Hazardous chemicals units shall report their emergency plans for hazardous chemical accidents to the people's production safety supervision and management department of the city divided into districts where they are located for the record.

In the event of a hazardous chemical accident, the safety management personnel of the accident unit shall immediately organize rescue in accordance with the emergency plan for hazardous chemicals of the unit, and report to the local production safety supervision and management department and the competent departments of environmental protection, public security and health; In the event of an accident involving hazardous chemicals in the course of road or water transportation, the driver, crew or escort shall also report to the competent department of transportation at the place where the accident occurred.

In the event of a hazardous chemical accident, the local people concerned shall immediately organize relevant departments such as production safety supervision and management, environmental protection, public security, health, and transportation to organize and implement rescue in accordance with the emergency plan for hazardous chemical accidents in the region, without delay or prevarication.

Relevant local people** and their relevant departments shall, in accordance with the following provisions, take necessary emergency response measures to reduce accident losses and prevent the spread and expansion of accidents:

Immediately organize the rescue and treatment of victims, evacuate, evacuate, or take other measures to protect other persons in the hazardous area;

Quickly control the source of hazards, determine the nature of hazardous chemicals, the hazard area of the accident and the degree of hazard;

In view of the actual and possible hazards caused by the accident to the human body, animals and plants, soil, water sources, and atmosphere, measures such as closure, isolation, and decontamination should be taken quickly;

Monitor and evaluate the environmental pollution and ecological damage caused by hazardous chemical accidents, and take corresponding environmental pollution control and ecological restoration measures Relevant hazardous chemical units shall provide technical guidance and necessary assistance for the emergency rescue of hazardous chemical accidents, and if environmental pollution caused by hazardous chemical accidents is caused, the competent departments of environmental protection of the people's governments at or above the municipal level divided into districts shall uniformly release relevant information.

Evacuate upwind. Because some of the gas will drift with the wind, if you go upwind, it won't go upwind, right? When in a low-lying area, evacuate quickly to a higher place. Because, it is easy to come to low-lying places to gather.

Hazardous chemicals refer to: natural gas, liquefied gas, pipeline gas, banana water and other paint thinners, gasoline, benzene, toluene, methanol, vinyl chloride, liquid chlorine (chlorine), liquid ammonia (ammonia, ammonia), sulfur dioxide, carbon monoxide, hydrogen fluoride, peroxide, cyanide, yellow phosphorus, phosphorus trichloride, strong acids, strong alkalis, pesticides and pesticides, etc.

Determine the source of the poison and the direction of the wind, and quickly evacuate the scene in the direction away from the source of the poison along the upwind or side-upwind route.

Hazardous Chemicals Storage Methods:

Separate storage. According to the danger of dangerous goods, the storage of hazardous chemicals is stored in accordance with the method of isolation, separation and separation

Segregated storage. That is, in the same room and in the same area, different materials are separated by a certain distance, and non-taboo materials are stored in a channel to maintain space.

Separate storage. Refers to the storage method of separating them from taboo materials with partitions in the same building or in the same area. <>

In the event of a hazardous chemical accident, evacuate in the upwind direction.

According to the "Basic Procedures for On-site Emergency Treatment of Hazardous Chemical Accidents":

Article 1 Isolation and evacuation.

Point 2 Emergency evacuation.

Quickly evacuate personnel in the warning area and polluted area who are not related to the emergency treatment of the accident to reduce unnecessary personnel**.

Attention should be paid in the event of an emergency evacuation:

Item 2 Shift to the upwind direction, specify a special person to guide and escort the evacuees to the safe area, and set up sentry posts on the evacuation or evacuation route to indicate the direction.

Note: For the evacuation work to proceed smoothly, each workshop should have at least two unobstructed emergency exits with clear signs.
