Which distance corresponds to the evacuation distance for a 5-pound fire?

• A. 150 feet
• B. 70 feet
• C. 100 feet
• D. 50 feet

Answer: (B)

Evacuation distance in a hazmat fire is based on the size of the fire and the level of hazard it can still pose at a distance. A five-pound fire represents a relatively small fuel load, but it can still flare, flash, or rupture a container, sending heat, flames, or burning fuel toward nearby people. The guideline sets a buffer zone of about 70 feet to keep responders and bystanders out of the most dangerous range while allowing safe access if needed for suppression or control. Stepping farther from the scene (like 100 or 150 feet) is typically reserved for larger fires or higher-risk scenarios where the potential for rapid flame spread, explosion, or toxic smoke is greater. Moving closer (around 50 feet) would increase the chance of injury from radiant heat, exposure to smoke, or sudden ignition. If wind shifts or environmental conditions change, adjust the distance accordingly, but for a five-pound fire, 70 feet is the standard protective distance.
