Class: 1
Placard type: Explosive 1.1D
ERG: Guide 112 (check current ERG)

Chemical & Response Details
| Also known as | DEGNDiglycol dinitrate2,2'-Oxybis(ethanol) dinitrateDiethylene glycol dinitrate desensitizedNitroglycol dinitrate |
| CAS Number | 693-21-0 |
| Appearance | Colorless to pale yellow oily liquid with a weak, sweet odor. Desensitized formulation contains phlegmatizing agents to reduce sensitivity. |
| Flash Point | Not applicable (explosive liquid) |
| Boiling Point | Decomposes at approximately 159C (318F) before boiling |
| Vapor Density | 2.4 (heavier than air) |
| Water Reactivity | Slightly soluble in water; no violent reaction but contamination may affect stability |
| Extinguishing | DO NOT USE WATER OR FOAM — may spread fire; use dry chemical or sand at safe distance only |
| PPE | ⚠️ Level A mandatory; full explosive ordnance disposal (EOD) protective gear recommended; SCBA required; avoid all static, friction, and shock |
| Isolation | ERG 112: Isolate 800m (0.5 miles) all directions; evacuate 1600m (1 mile) downwind if material involved in fire; treat as mass explosion hazard |
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.
