What fire division is posted when the hazard is a mass explosion?

• A. Division 1
• B. Division 2
• C. Division 3
• D. Division 9

Answer: (A)

When a fire division is posted, it shows how severe the explosion hazard could be and how it might propagate. A mass explosion is the most severe scenario, where a large quantity of energetic material could detonate and produce a blast that affects a wide area. That level of risk is signaled by Division 1, which tells responders to treat the scene as a mass explosion hazard and implement aggressive protective measures, isolation, and careful cooling or containment as appropriate. The other divisions describe less severe or different types of hazards and don’t indicate the broad blast potential of a mass explosion, so they aren’t the correct posting for this situation.
