Can 75% Alcohol Be Carried in Private Cars?
1 Answers
From a safety perspective, it is not recommended to store 75% alcohol in private cars. Here are the relevant details: 1. High risk of spontaneous combustion and explosion: Alcohol left in a car during summer can self-ignite. The common 75% medical alcohol has a flash point of 20 degrees Celsius, while outdoor temperatures at noon in summer can exceed 40 degrees Celsius. When a car is parked outside under direct sunlight, the interior temperature can rise to over 50 degrees Celsius, significantly increasing the risk of alcohol self-ignition and explosion. 2. Ensure proper ventilation: Since the flash point of alcohol is only 20 degrees Celsius, high temperatures inside the car may cause combustion. Therefore, it is best to avoid storing alcohol in the car. If disinfection is necessary, find an open area to wipe the car interior with alcohol and ensure adequate ventilation for a period afterward. 3. Avoid using alcohol on leather seats: When using alcohol inside the car, if the seats or steering wheel are made of genuine leather, directly spraying alcohol on the leather can cause damage. Alcohol is an organic solvent, and especially in cars with lower-quality leather, it may change the smooth, uniform color into a texture resembling that of a jaguar.
