For a Class B fire of appreciable depth, what is the maximum travel distance allowed?

For fires classified as Class B, which involve flammable liquids and gases, the proper response requires careful consideration of the layout and accessibility of fire extinguishers. The National Fire Protection Association (NFPA) guidelines typically state that the maximum travel distance to reach a fire extinguisher for Class B fires should not exceed 50 feet. This distance is determined based on the potential spread of flammable liquids and the necessity for a rapid response to prevent further fire escalation.

Maintaining a 50-foot distance ensures that individuals can quickly access an extinguisher without jeopardizing their safety, as closer access may lead to increased risk of exposure to flames or toxic fumes. The available literature on fire safety also emphasizes that accessible extinguishers are crucial in the immediate response plan, especially with the fluid nature of Class B fires.

The other options provide distances that fall short of the established safety standard, potentially leading to delayed intervention and increasing risks associated with deeper fires. Overall, recognizing the importance of the correct travel distance is vital for ensuring effective and safe fire response measures in environments susceptible to Class B fire hazards.
