UN 3317 At a Glance
UN 3317 (2-Amino-4,6-dinitrophenol, wetted with not less than 20% water) is listed as DOT Class 4 Flammable Solid and is assigned to ERG Guide 113. Use this page to review placard data, common hazards, PPE notes, isolation context, first actions, and related UN numbers.
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.
