If a leak is suspected but the source cannot be located, what is the safest course of action?

• A. Turn on ventilation and continue searching.
• B. Evacuate and report to supervision or emergency services.
• C. Ignore and wait for the leak to stop.
• D. Use water to flush the area.

Answer: (B)

When a propane leak is suspected and the source can’t be located, the priority is to get people out of the area and notify supervision or emergency services. Propane is heavier than air and can collect in low spots, creating a significant fire or explosion risk even without obvious symptoms. Trying to search for the leak or turning on ventilation can push or spread the gas, potentially bringing it into contact with ignition sources. Ignoring the leak or waiting for it to stop offers no safety and can allow dangerous vapor to accumulate. Water won’t fix a gas leak and doesn’t address the hazard either. Evacuating and reporting gives trained personnel the chance to locate and shut off the source and confirm the area is safe before anyone returns.
