What must be turned off before filling a motorhome with propane?

When filling a motorhome with propane, it is essential to turn off all pilots and burners to ensure safety during the refueling process. Pilots and burners represent open flames, which can ignite propane, leading to fire hazards or explosions. Propane is highly flammable, so any source of ignition must be controlled to prevent accidents during refueling.

While turning off lights, refrigeration units, or all electrical appliances may be good practice in many situations, they are not as critical as ensuring that all pilots and burners are extinguished. Lights typically do not pose a flame risk, refrigeration units may operate safely as they are designed for such situations, and electrical appliances may not necessarily be a fire risk as long as they do not create open flames. The focus on turning off pilots and burners directly addresses the most significant safety concern when handling propane.
