Which distance is correct for wet chemical containers relative to hazard?

• A. 5 to 10 feet
• B. 10 to 20 feet
• C. 20 to 30 feet
• D. Directly adjacent

Answer: (B)

The idea here is to maintain a safe buffer between wet chemical containers and the hazard so that any heat, splash, or accidental release is less likely to affect people or the ignition area. Keeping wet chemical containers ten to twenty feet away from the hazard provides enough space for safe evacuation, for responders to reach extinguishers, and for the area to remain protected from heat transfer or splatter. It’s close enough to be practical and far enough to reduce risk, whereas being directly adjacent or only five to ten feet away offers insufficient separation, and twenty to thirty feet can create unnecessary distancing without adding meaningful safety gain.
