What is a key hazard trait of Class 1 explosives when exposed to fire?

• A. Release energy rapidly
• B. Become inert
• C. Need water to detonate
• D. Produce a calming effect

Answer: (A)

When a Class 1 explosive is exposed to fire, the critical hazard is the rapid release of energy. Class 1 materials are low explosives that can burn quickly and, under the right conditions, can detonate or deflagrate when heated. This sudden release creates a powerful blast and overpressure, along with potential fragmentation, which is the primary danger in a fire scenario. The other options don’t fit because these materials don’t inherently become inert from heat, they don’t require water to detonate, and they certainly don’t produce a calming effect. The emphasis here is on how quickly energy is released in a fire, driving the blast and fragmentation risks you must anticipate.
