gas accidents can lead to serious consequences, so we should make emergency plans for gas accidents. The following is my emergency plan for gas accidents. Welcome to read it.
emergency plan for gas accidents
1. guiding ideology
seriously implement the national safety production law and establish? Safety first, prevention first? The idea of strengthening the emergency treatment of gas emergencies, highlighting? People-oriented? The principle of practical implementation? Hidden dangers are more dangerous than open flames, prevention is better than disaster relief, and responsibility is more important than Mount Tai? Safety management awareness, to ensure the safety of the state, citizens' property, life and society.
II. Purpose of compilation
In case of gas emergency, the situation can be controlled quickly, actively, orderly and effectively, and the accident loss can be minimized.
III. Compilation basis
3.1. Law of the People's Republic of China on Work Safety.
3.2. The People's Republic of China * * * and the Ministry of Construction, the Ministry of Labor and the Ministry of Public Security No.11 "Regulations on Town Gas Safety".
3.3. Regulations of the People's Republic of China and the Ministry of Construction No.62 on the Management of Town Gas.
3.4. the industrial standard of the people's Republic of China, Technical Specification for Safety in Operation, Maintenance and Emergency Repair of Town Gas Facilities.
3.5. Interim Provisions on the Investigation Procedure of Extraordinary Major Accidents (Decree No.34 of the People's Republic of China and the State Council).
IV. General situation of the project
The reconstruction and expansion project of Changde Avenue in Changde City starts from Jindan Road in the northwest and ends at Yuanshui Second Bridge in the southeast. The total length of the road is 14191.165m (except for 1852.122m from Longgang Road to Wuling Avenue). The starting and ending pile numbers of Jindan Road to Longgang Section are K1+111 ~ K2+641, and Wuling Avenue to Yuanshui Second Bridge.
There are gas pipelines on the right side of the original road from K5+111 to K14+911 on Changde Avenue, and there are many gas pipelines with complicated locations, so they have not been moved yet. In order to create construction conditions and speed up the construction progress, according to the opinions of the construction unit and supervision unit, it is planned to excavate the rain and sewage pipeline on the right side outside the safe distance of the gas pipeline, and this plan is specially formulated to prevent accidents that damage the gas pipeline during construction.
the gas pipeline in the second work area is located on the right side of the road, with irregular direction and buried depth, and a branch pipe with a length of about 1.5 ~ 2m is set at a certain distance, with valves.
during trench excavation of rain and sewage pipelines and road intersection construction, the location and quantity of original gas pipelines should be investigated first, and the gas company should come to make disclosure before the excavation. During the excavation, the gas company should have a special person on site to monitor and prevent the original pipelines from being damaged by the construction and causing accidents.
V. Identification of hazard sources
(1) Basic characteristics of all kinds of fuel gas
5.1.1. Natural gas
(1) The main component is methane;
(2) the calorific value is about 35.53～37.62MJ/m/m;
(3) the proportion of natural gas is 1.56; (4) The explosion limit is 5 ~ 15%.
5.1.2. Air mixed gas (mixture of liquefied petroleum gas and air)
(1) The main components are C3 and C4;
(2) the calorific value is about 51.16MJ/m;
(3) The specific gravity of air-air mixture is 1.41;
(4) the explosion limit is 3.5 ~ 16.81% (volume ratio).
the above parameters are calculated data in the standard state.
(2) Classification of accident causes
5.2.1. Collapse;
5.2.2. Leakage: pipeline interface leakage, pipeline body leakage, gas storage equipment leakage, other pipeline equipment leakage and gas equipment leakage;
5.2.3. People are poisoned or killed;
5.2.4. Fire;
5.2.5. deflagration.
(III) Cause analysis of accidents
The main causes of gas pipeline accidents are:
(1) The gas pipeline is loose or even broken due to barbaric construction and overloaded vehicles;
(2) brutally demolishing old houses or illegally building damaged gas pipelines.
(3) There is a big difference between the buried underground pipeline and the provided data, which causes damage accidents.
VI. Preventive and emergency measures

After the collapse, the principle of first aid is to rescue the people in distress first. Secondly, in the rescue process of landslides, it is often? Landslide again? Rescue workers are injured, which requires special attention.
(1) First-aid methods for people buried all over the body
When the whole person is buried in a landslide, we should immediately organize forces to rescue them. If not treated correctly in time, it can cause death. When the position of the buried person is clearly known, when approaching the injured person,
it is necessary to prevent accidental injury when digging with rescue tools, and try to dig by hand. In emergency rescue, attention should be paid to the housing frame, broken walls, bricks and tiles near the wounded to prevent collapse during excavation.
(2) First aid for the injured after the landslide
The first aid methods for the injured after the landslide are as follows:
① Rescue the wounded quickly;
② When rescuing the scene, move carefully, and it is forbidden to drag the wounded and aggravate the injury;
③ Remove the silt and sputum in the mouth and nose, and give artificial respiration to those who have difficulty breathing or stop breathing; The bleeding victim must stop bleeding; The fracture patients were transported after local fixation. When the patients with cervical vertebra fracture are transported, one person should hold the head of the injured person and pull it slightly, and sandbags should be placed on both sides of the head to fix it; (4) feed a small amount of salt water after the wounded are awake; ⑤ Send to the hospital for emergency treatment.
6.2. Emergency measures for gas leakage:
(1) After the gas accident, the person on site (witness, unit or individual) has the responsibility and obligation to report to the gas supply enterprise and the emergency agencies of relevant departments by telephone, and the telephone number of the person in charge of the gas company is 1736-7763117; Safety Supervision Department Tel: 1736? 7713281。

Self-rescue methods for gas leakage:
(1) After gas leakage occurs, cover your nose and mouth with handkerchiefs, napkins, clothes and other readily available items immediately. If you have water or drinks on hand, you'd better soak your handkerchief, clothes, etc.
(2) When gas leaks, don't panic, choose to escape along high places or low places, but don't stay in low places.
(3) In case of gas leakage, it is necessary to judge the source and direction of gas, and quickly evacuate the site in the direction away from the gas source along the windward or crosswind route, so as to prevent the gas from drifting with the wind, and not to stay in low-lying places.
(4) In case of gas leakage, if there is a special person at the scene of the accident, they should obey their guidance and arrangement.
6.3. Emergency measures for fire accidents caused by gas leakage:
(1) Necessary measures should be taken to control and extinguish the flames to prevent the situation from getting worse;
(2) the fire department shall be notified immediately;
(3) cooperate with the fire department to put out the fire after the fire is controlled.
Self-rescue methods in case of fire:
(1) Covering your eyes and nose with towels or clothes soaked in the fire will make you persist for a long time, thus giving firefighters more time to save themselves.
(2) First, calm down, determine your position, judge the fire according to the surrounding smoke, light and temperature, and choose the best escape method.

Emergency Plan for Gas Accidents Part II
The gas (natural gas, liquefied petroleum gas) used by urban residents is flammable and explosive, and once it leaks, it is easy to cause combustion and explosion accidents. Any gas needs oxygen (air) supply to burn. When using gas in a closed space, if the gas appliance leaks, the gas burns incompletely or lacks fresh oxygen supply, it will cause carbon monoxide poisoning, suffocation and even death.
gas leakage
sudden scene
if you smell gas smell in your home, you should pay attention to it immediately and take measures to avoid casualties.
rescue measures
1. turn off the gas pipeline or the valve of liquefied gas cylinder quickly.
2. Open the doors and windows immediately and strengthen the ventilation.
3. it is forbidden to turn on and off the electrical appliances and put an end to all kindling.
4. when the gas pipeline or gas stove is on fire, quickly close the indoor gas pipeline control valve or steel cylinder angle valve. If the LPG cylinder catches fire, it can be covered with a dry powder fire extinguisher or a large piece of wet rag to put it out, and the valve can be closed quickly.
5. If you find a large amount of gas leakage, you should leave the scene as soon as possible, and tell your neighbors to put out the fire and evacuate, and don't rush into the room with strong gas odor.
6. give an alarm to the gas supply unit, gas management department and fire department in a safe zone.
Expert tip
1. It is forbidden to use matches or lighters to find the air leakage of gas appliances or pipelines. The common leak detection method is to apply soap liquid to the joints and pipe fittings to see if there are bubbles.
2. Do not repair or install gas appliances by yourself. You should buy special gas hoses and matching hose buckles, pressure reducing valves, etc. from designated or regular shopping malls.
3. It is forbidden to use the adjustable liquefied gas pressure reducing valve. Check and replace the hose regularly (the service life of the hose shall not exceed 18 months). The length of air hose should not exceed 2m.
4. Please choose stoves and water heaters with automatic flameout protection devices.
5. Don't seal indoor gas pipeline facilities under closed cabinets and stoves, so as not to affect normal use, overhaul and maintenance.
6. It is forbidden to use coal stoves and gas stoves at the same time in the kitchen.
7. Use liquefied petroleum gas cylinders in strict accordance with relevant regulations.
gas water heater accident
sudden scene
when using gas water heater, you should quickly identify the smell and take timely measures.
rescue measures
1. See page 73 of this manual? Gas leak? Articles 1, 2 and 3 of the rescue measures.
2. Call the gas company or manufacturer for repair in a safe place.
Expert tip
1. The type of gas water heater should be consistent with the type of gas used, and cannot be mixed. Buy a water heater with automatic flameout protection device.
2. combustible materials and wire switches should be avoided at the top of the gas water heater and at a safe distance to ensure safety.
3. The gas water heater must be equipped with a flue to discharge the flue gas to the outside. It is forbidden to install gas water heaters and their flues on wooden walls.
4. Choose the location where the gas water heater is installed, and do not install it.
