Will 75 Degree Alcohol Explode in the Sun

Alcohol with a concentration of 75% is prone to explosion when exposed to sunlight. Being a flammable liquid, it has a flash point of 20°C, and during summer, the outdoor temperature can soar above 40°C, greatly increasing the risk of alcohol spontaneously combusting and exploding in the sun.

To safely store 75% alcohol, it should be kept in a cool, well-ventilated place where the temperature does not exceed 30°C. The container needs to be securely sealed and stored separately from oxidizers, acids, alkali metals, and amines to prevent any hazardous interactions. Employing explosion-proof lighting and ventilation systems is advised, along with a strict ban on machinery and tools that could generate sparks.
