Source Title: Use of 75% Alcohol for Disinfection Needs Fire Prevention
Recently, the topic "new type of coronavirus is afraid of alcohol intolerance to high temperature" appeared on the hot search, experts pointed out that 75% of alcohol can effectively inactivate the virus. Liu Bingtao,
head of the Propaganda Section of Beijing Daxing District Fire Rescue Division, reminded residents that when 75% alcohol is used for disinfection at home, the volatilization of alcohol will increase the flammable gas in the indoor air. As long as there is a small spark in the air, it may cause flash ignition. This is more dangerous than alcohol being ignited!
For fire safety, what are the hidden dangers of alcohol fires? Liu Bingtao said that the alcohol used in daily life at a concentration of 75% (ethanol) can effectively inactivate the virus. With the development of new coronavirus epidemics, residents mostly use medical alcohol for daily disinfection, but high-concentration alcohol is flammable and explosive, and it is easy to cause fire.
"This is because alcohol contains ethanol, and ethanol is a Class A liquid, with a flash point of less than 28 ? C and a lower explosive limit of less than 10%. That is to say,
alcohol is flammable, and there is a danger of fire and explosion when exposed to heat or fire," Liu Bingtao reminded When the concentration of alcohol used in the home is higher than 70%, the volatilization of alcohol increases the flammable gas in the indoor air, especially when the alcohol content in the air reaches 19% and the temperature is equal to or higher than 13 ? C. Mars will flash, which is more dangerous than alcohol being ignited.
Therefore, after spraying alcohol to disinfect clothing, furniture, etc., if the smell of alcohol in the house is very strong, do not contact it with open flames at this time, such as cooking with a gas stove, smoking, etc., including the use of some electrical switches. There is also a danger of explosion. , Need to pay great attention.
How to extinguish alcohol once it catches fire? Liu Bingtao said that alcohol burned on his body, and his clothes should be quickly removed, and then the fire on the clothes should be extinguished. If the clothing cannot be taken off, someone needs assistance. Cover the fire area with a wet towel, etc., and extinguish the fire by blocking the air. When using alcohol to ignite items such as furniture, be sure to cover the ignition point with a fire extinguisher in your home or wet items such as wet towels.
