Chemical & Response Details
| Also known as | Type B blasting explosiveCommercial blasting agentHigh explosive blasting compoundDetonating explosive type B |
| Appearance | Solid material, typically brown or tan in color. May be in the form of cartridges, sticks, or bulk powder. Odorless or slight chemical odor depending on composition. |
| Flash Point | Not applicable (explosive solid) |
| Boiling Point | Not applicable (decomposes violently) |
| Vapor Density | Not applicable (solid explosive) |
| Water Reactivity | Generally stable in water but some formulations may be water-sensitive. Do not apply water directly to burning explosive. |
| Extinguishing | Do not fight fire when material is involved. If fire must be fought, use flooding quantities of water from distance. No foam or dry chemical effective. |
| PPE | ⚠️ Maximum standoff distance required. Full structural firefighting protective clothing provides limited protection. SCBA mandatory. Approach only if absolutely necessary for life safety. |
| Isolation | ERG 112: Initial isolation 500 meters in all directions. Evacuate 1600 meters in all directions if material is on fire or release involves fire. Consider larger distances for bulk quantities. |
Chemical details are general reference only. Always verify with current SDS, ERG, and SOP/SOG.
