Quick details
UN 0118
Class: 1
Placard type: Explosive 1.1D
ERG: Guide 112 (check current ERG)
Isolation: ERG 112: isolate 500m minimum all directions. Evacuate 1600m in all directions if material is on fire or exposed to heat. Mass explosion hazard — do not approach.
Chemical & Response Details
| Also known as | HexoliteHexotolRDX/TNT mixtureComposition B variantHexogen-TNT explosive |
| Appearance | Pale yellow to tan granular or pressed solid explosive composition. Odorless or faint aromatic odor. Remains solid at room temperature. |
| Flash Point | Not applicable (explosive solid) |
| Boiling Point | Not applicable (decomposes violently upon heating) |
| Vapor Density | Not applicable (solid) |
| Water Reactivity | No significant reaction with water, but water should not be used for fire suppression |
| Extinguishing | DO NOT use water, foam, or CO2. Fighting fire may cause detonation. Evacuate area immediately if involved in fire. |
| PPE | ⚠️ Full structural firefighting gear with SCBA required if approach is absolutely necessary. Level A with blast-resistant cover strongly recommended. |
| Isolation | ERG 112: isolate 500m minimum all directions. Evacuate 1600m in all directions if material is on fire or exposed to heat. Mass explosion hazard — do not approach. |
Chemical details are general reference only. Always verify with current SDS, ERG, and SOP/SOG.
Common hazards (high level)
- Mass explosion hazard — entire load may detonate simultaneously.
- Severe blast overpressure and fragmentation.
- Sensitive to heat, shock, and friction.
- Secondary fire and debris hazard.
First actions (field-minded)
- CALL 911. Then call emergency response telephone number on shipping paper.
- Establish large isolation zone — minimum 500 meters in all directions.
- Stage upwind, uphill; limit personnel to essential responders only.
- Request Hazmat + law enforcement + additional resources immediately.
- Do not fight fire — evacuate and isolate; let burn if no life safety risk.
- Protect exposures only if safe and directed by command.
- Consult current ERG Guide 112 and follow SOP/SOG.
