The bubble test
The soapy water bubble test is the standard method for detecting propane leaks. Mix dish soap with water and apply to the valve, regulator, and hose connections. Open the tank valve slowly. Bubbles indicate escaping gas.
NFPA recommends this check at the start of every grilling season, after any tank change, and whenever you smell gas near propane equipment. Never use a match or lighter to check for leaks.
Upright, outdoor, ventilated
Store propane tanks upright (never on their side), outdoors, in a ventilated area, away from ignition sources, building air intakes, and direct sunlight. Never store propane indoors, in a basement, or in a vehicle trunk. Propane is heavier than air and pools in low areas.
Tanks should not be stored above 120 degrees F. In extreme heat, move tanks to shade.
Ventilation and shutoff
Any propane appliance used in an enclosed space must be rated for indoor use (some catalytic heaters are, most are not). When in doubt, use it outdoors only. Always shut off the tank valve when the appliance is not in use.
