Prevention of gas poisoning
1, gas safety regulations and technical operation regulations must be strictly implemented.
2, gas unit mount guard personnel must pass the exam before mount guard, otherwise can't mount guard.
3, when hot on the gas equipment maintenance, must do hot card, protection personnel to the scene monitoring or can't work.
4, into the gas equipment internal work, must first cut off the gas source, after more than 2 hours of ventilation, pigeon experiment or carbon monoxide content analysis, with the consent of the gas protection personnel, can enter the operation, and guardianship by designated personnel.
5, gas equipment, especially indoor equipment should have a regular leak detection system, found leakage, timely treatment.
6, strictly abide by labor discipline, it is forbidden to stay in the gas area, rest or sleep.
7. The steam pipeline cannot be connected with the gas pipeline for a long time, and it should be disconnected immediately after use to prevent gas poisoning accidents caused by gas channeling. Water pipes should be equipped with check valves to prevent gas channeling when water is cut off.
8, when working with gas, you must wear a gas mask, not foolhardy and by experience.
9, gas area should be hung with obvious safety signs.
Treatment after gas poisoning accident
1, the scene of the accident, should immediately keep watch, it is forbidden to enter the gas area without wearing a gas mask.
2. Make the poisoned person leave the scene quickly. If it is indoors, move it outdoors or to a safe place with good ventilation.
3, rescue gas poisoning, should take corresponding measures according to the degree of poisoning.
4. For mild poisoning, such as headache, nausea, dizziness and vomiting. Breathing fresh air or properly supplementing oxygen can quickly eliminate its symptoms.
5, for moderate poisoning, such as vague will, foaming at the mouth and other symptoms, should immediately on-site oxygen, after being conscious and breathing normally, and then sent to a nearby hospital for treatment, if there is a hyperbaric oxygen chamber can be treated.
6, for severe poisoning, such as symptoms such as loss of consciousness, respiratory arrest, should immediately implement artificial respiration, before regaining consciousness, are not allowed to be transported to a distant hospital by car, in the case of poisoning without lividity or without the permission of the medical staff, shall not stop the first aid.
7. While rescuing the poisoned personnel, the scene of the accident should be controlled, and it is forbidden for kindling and other personnel to enter, and the air circulation at the scene should be maintained. Indoor doors and windows should be opened for ventilation to discharge harmful gases and dilute them. In places where natural ventilation is difficult, artificial forced ventilation should be adopted.
8, strictly check the scene of the accident, find out the leak for repair.
Two conditions of gas ignition
1, there should be enough air or oxygen.
2, should have an open flame, ignite or reach different ignition temperature of various gases.
Combustion conditions
1, flammable substance
2, there are combustion-supporting substances
3. There is a fire source
The above three conditions are indispensable in the combustion process, which are collectively called the three elements of combustion. However, even with the three elements of combustion, it is not necessarily spontaneous combustion. Therefore, the three elements of combustion are only three necessary conditions for combustion. Combustion will occur only when the three elements of combustion meet certain conditions.
Prevention of gas fire accident
1, the tightness of gas facilities, and handle gas leakage in time.
2, gas facilities should have good grounding device, grounding wire should be regularly checked and tested.
3, strictly implement the gas facilities and gas area hot work management system, should be handled in advance when hot card, should have safety measures, and confirmed by the security department, according to the requirements of the specified time and place when hot.
4, should try to avoid gas operation, if necessary, must be carried out under reduced pressure conditions, and must use copper tools, such as iron tools, must be coated with butter on the working face.
5. Exposed high-temperature pipes should be insulated near the workplace with gas.
6. Flammable and explosive articles are not allowed to be piled up near gas facilities.
Treatment of gas fire accident
1. A slight leak caused by loose facilities, wet mud, wet sacks, etc. caused a fire. Can be used to block the fire site, after the fire is extinguished, the leak should be repaired according to relevant regulations.
2. When the gas pipeline is on fire, if the pipe diameter is below 100mm, the gas fire source can be directly cut off. If the pipe diameter is greater than 100mm, the gas pressure should be gradually reduced, but the gas pressure should not be less than 49? 98Pa(5？ 10mmH2O), pipeline fire caused by gas pressure drop can be blocked and covered with yellow mud, wet sacks and asbestos cloth. , can also be put out with steam or a fire extinguisher. Don't put out the fire before the gas pressure drops in a poorly ventilated place, otherwise the gas will still leak a lot after the fire is put out, forming explosive gas. In case of hot facilities or sparks, it may cause an explosion.
3. When sediments (such as tar, iron sulfide, etc. ) When the gas facilities catch fire, all auxiliary holes connected with the atmosphere, such as manholes and radiation holes, can be closed to isolate them from the air and extinguish the fire naturally. At the same time, steam or nitrogen should be introduced, and the gas source should be cut off after fire extinguishing, and then treated according to relevant regulations. But don't stop sending steam or nitrogen immediately after the fire, so as to avoid spontaneous combustion of sediments in the facility and cause explosion.
4. When the gas facilities are red-hot, it is forbidden to quench with water to prevent the gas facilities from being deformed, broken and leaked due to sharp contraction.
5, gas valve, water seal, pressure gauge, steam or nitrogen pipe fittings, etc. Someone should control the operation.
6. Before the ventilation is resumed after the fire alarm is lifted, it should be carefully checked to ensure that the explosion-proof pipeline facilities are in good condition, and ventilation is allowed after the replacement operation.
Prevention of gas accidents
1, strengthen gas safety management, conduct training and assessment on production operation and safety technology for gas operators, and allow them to take up their posts only after they are qualified, and formulate and implement strict post responsibility system.
2. Starting from the tightness of the production facilities, improve the automation degree of the CO production system, and prevent and reduce the CO concentration that is harmful to people's health and safety in the production environment.
3. Strengthen the detection and alarm of carbon monoxide concentration in the production environment. The maximum concentration of carbon monoxide is not allowed to exceed 24PPm.
4, equipment or pipeline maintenance, first of all, the equipment or pipeline gas purging clean, new or overhaul of gas equipment and pipelines to strength and tightness test.
5, when working in the gas area, must be more than two people, one homework, one care, and regularly notify the gas protection station personnel to analyze the CO content on a regular basis, in case of gas leakage, must stand on the windward side care, it is forbidden for anyone to enter the dangerous area, and immediately notify the relevant units for processing.
