What maximum travel distance is recommended for using a portable fire extinguisher for Class B fires?

The maximum recommended travel distance for using a portable fire extinguisher on Class B fires is 50 feet. This guideline is based on the characteristics of Class B fires, which involve flammable liquids, gases, or greases, and can spread rapidly. The 50-foot distance allows for a quick response while remaining within a safe range to effectively use the extinguisher on the fire without putting the user at risk from flames, heat, or smoke.

By adhering to this recommendation, individuals can ensure they are close enough to the fire to effectively apply the extinguishing agent while avoiding the potential dangers associated with a larger fire or hazardous materials. This distance helps to maximize the chances of successfully extinguishing the fire before it escalates or spreads further.
