Explosive, blasting, type B is a highly hazardous substance that requires careful handling and storage. It is typically used in mining and construction applications, and its improper use can lead to severe consequences.

Hazard overview: The substance poses a mass detonation hazard, and its severe blast and fragmentation can cause significant damage. It is essential to exercise extreme caution when handling this material, as it can be highly unstable and sensitive to heat and shock.

Response guidance: In the event of an emergency, it is crucial to maintain a safe distance from the substance and evacuate the area immediately. Firefighters should approach the scene with caution, wearing full structural firefighting protective clothing and SCBA, and only if absolutely necessary for life safety.
