⚠️ Verification required:
Broad or variable material category; verify exact product, SDS and shipping papers.
⚠️ This page is a quick-reference aid. For real incidents: stage upwind, isolate, deny entry, request Hazmat early, and consult the current ERG + SOP/SOG.
UN 3317 is 2-amino-4,6-dinitrophenol wetted with at least 20% water to reduce sensitivity. The water content is critical because dried material may behave like an explosive.
Hazard overview: The wetted solid may burn, and dried material may explode if exposed to heat, flame, friction, or shock. Dust, impact, and drying are major control concerns.
Response guidance: Keep the material wet, avoid friction or rough handling, isolate the area, and treat any dried or fire-involved material as explosive. Use water spray to maintain wetting from a safe distance when appropriate.

Isolation & Evacuation
ERG 113: isolate spill area at least 25m in all directions; if material dry or fire involved, treat as explosive and increase isolation significantly
Always confirm protective actions with the current edition of the Emergency Response Guidebook (ERG Guide 113).
First Actions for a UN 3317 Incident
- Keep unauthorized personnel away.
- Stay upwind, uphill and/or upstream.
- Ventilate closed spaces before entering, but only if properly trained and equipped.
- Isolate spill or leak area immediately for at least 100 meters (330 feet) in all directions.
- Consider initial evacuation for 500 meters (1/3 mile) in all directions.

Frequently Asked Questions about UN 3317
When properly wetted it is desensitized, but dried material should be treated as explosive.
Water reduces sensitivity to heat, friction, shock, and ignition.
Avoid drying, friction, shock, sparks, flames, and unnecessary handling.
SCBA, full protective clothing, and remote handling precautions are needed.
ERG Guide 113 applies for initial response.
