In indoor propane use, what hazards can occur?

• A. Fire risk only
• B. Asphyxiation from gas displacement of air
• C. Temperature drop
• D. Fire or explosion risk and asphyxiation from gas displacement of air

Answer: (D)

Propane indoors brings two main dangers: its flammability and its ability to push air out of a space. When propane leaks, it can gather near the floor because it’s heavier than air, gradually reducing the amount of breathable oxygen and creating an asphyxiation risk. At the same time, propane can mix with air to form explosive concentrations, so any leak with a spark or flame can ignite and cause a fire or explosion. Temperature drop isn’t a primary hazard in this scenario, so the strongest concerns are the risk of fire or explosion and the danger of asphyxiation from displaced air.
