Which statement about propane leaks in enclosed spaces is correct?

Propane can accumulate and create a flammable, potentially explosive atmosphere.

Propane leaking in enclosed spaces can accumulate, creating a flammable and potentially explosive atmosphere. When a release occurs in a confined area, the gas can build up because there’s limited fresh air to dilute it. If the concentration reaches the right range and a spark or flame is present, ignition can occur, leading to a fire or explosion. Ventilation is crucial: good airflow helps disperse the gas and lowers the risk by preventing buildup.

Propane doesn’t dissipate instantly, even with some ventilation, and the idea that it always sinks to the floor is too absolute—air movement and drafts can mix the gas throughout a space. Exposing people to propane in an enclosed area is not safe, even for short periods, because a leak can quickly reach dangerous concentrations if not addressed.

Propane dissipates instantly regardless of ventilation.

Propane is heavier than air and always sinks to the floor.

Propane exposure is safe in enclosed spaces for short periods.
