Dangerous characteristics of alcohol
Alcohol, the scientific name of alcohol, is a flammable, volatile, colorless and transparent liquid under normal temperature and pressure, with a flash point of 13 ℃, and a light blue flame. Its vapor is heavier than air, and can spread to a far place at a lower place, forming an explosive mixture with air, which can cause explosion and combustion in case of open fire and high heat.
Search the Internet, because alcohol causes fire is not only a few.
Alcohol considerations
1. Pay attention to indoor ventilation when alcohol is used indoors, it is necessary to ensure indoor ventilation. Cloth cleaning tools such as used towels should be cleaned with a large amount of clean water after use, and then stored in a closed manner, or dried in a ventilated place.
2. Before the safe use of alcohol, the surrounding flammable and combustible materials should be cleaned up, and do not spray directly in the air. Alcohol has a low ignition point. It is easy to self ignite in case of fire or heat. When using, do not close to the heat source and avoid open fire. To disinfect the surface of electrical appliances, turn off the power supply first and wait for the electrical appliances to cool down before proceeding. If you wipe the kitchen stove with alcohol, turn off the fire source first to avoid the explosion caused by alcohol volatilization. During use, the upper cover of the container must be closed immediately after each use, and it is strictly prohibited to open it.
3. It is not suitable to store a large amount of alcohol in the home, which is a flammable and volatile liquid. When the residents use alcohol to disinfect the home, they can buy small bottles of alcohol, which is suitable for sufficient use. Do not store a large amount of alcohol, so as to avoid leaving a fire safety hazard.
4. The containers used for collecting, storing and using alcohol shall be reliably sealed and the containers without cover shall not be used. Glass bottles shall be avoided to prevent falling and damage. The rest of the alcohol in the home should not be placed in the balcony, stove and other heat source environment, or near the power socket, the wall, the corner of the table and other places to prevent accidental collision and dumping. Store in a cool place, such as a cabinet, in a dark place. When storing, close the cover and label to avoid volatilization.
5. When storing, children should not get to the family with children. Alcohol should be kept out of children's reach. For older children, parents can explain the characteristics of alcohol to their children, teach them not to play with alcohol, let alone light it with fire.
In this case, the Fire Department reminded the residents to use alcohol properly and keep away from open fire so as to prevent burning, scalding, fire and other accidents
What about alcohol fire? 1. Soak clothes, tablecloths, sheets or quilts in water and cover them with fire.
2. Then pour water continuously to the fire until it goes out.
3. When the fire starts, it is most likely to go out. Try to use the things around you.
4. Don't put out the fire in the direction of people or inflammables.
5. When the alcohol in the laboratory is on fire, do not blow it with the mouth when the alcohol furnace is out. Use the lamp cap to cover it twice more.
6. If alcohol leaks carelessly and leads to a fire, cover the fire with a wet cloth and cause the flame to be out of oxygen.
In case of alcohol fire
How to save yourself? After being burned, the first thing is to put out the fire. The correct Countermeasures for the injured should include the following:
First, take off your clothes immediately. Clothes stained with alcohol have become combustibles. The fastest way to remove clothing and heat source can minimize damage and consequences.
Second, avoid shouting. Shouting can cause severe respiratory burns when the head and face are surrounded by flames. Respiratory burn is one of the three major causes of death in burn patients.
Third, try to put out the fire. It is better to cover with cotton fabric or wash with water nearby, and see a doctor immediately after the fire goes out.
