Why is it crucial to wear gloves when handling propane?

Wearing gloves when handling propane is particularly important to prevent freezing the skin. Propane exists under high pressure and, when released or handled improperly, can cause rapid evaporation and a drop in temperature, leading to frostbite or cold burns. The liquid form of propane is much colder than the ambient temperature, and direct skin contact can result in serious injuries. By wearing appropriate gloves, individuals can effectively insulate their skin from these extreme cold temperatures, reducing the risk of injury.

While protection from chemical exposure, preventing abrasions, and keeping hands warm are also considerations in handling hazardous materials, the risk of skin freeze due to the extremely low temperature of propane is the primary concern that necessitates the use of gloves.
