What alternate method is acceptable for controlling emergencies with propane besides an 18lb BC rated extinguisher?

Using large amounts of water or spray as an alternate method for controlling emergencies involving propane is effective because water can dissipate heat and help separate the fuel source from the flames. In the case of propane fires, one of the primary concerns is controlling the fire from spreading and ensuring safety. Water can help cool surrounding surfaces and can even be used to create a barrier against the flames if applied in sufficient quantities.

While other options, such as a small bucket of sand or foam extinguishers, might also assist in mitigating a propane fire, the effectiveness of water in cooling and preventing the spread of flames makes it a widely endorsed method in emergency response situations involving propane. Fire blankets may not be practical for larger flames or gas fires, as they’re typically used to smother small fires.
