UN 2006 Quick Details
UN 2006
Product name: Plastics, nitrocellulose-based, self-heating, n.o.s.
DOT Class: 4
Placard type: Spontaneously Combustible
ERG Guide: 135 (check current ERG)
Initial isolation: ERG 135: isolate spill area minimum 25m in all directions; if material is on fire or involved in fire, isolate 800m in all directions and consider evacuation
Common Hazards of UN 2006
- Flammable/combustible material.
- May ignite on contact with moist air or moisture.
- May burn rapidly with flare-burning effect.
- Some react vigorously or explosively on contact with water.
- Some may decompose explosively when heated or involved in a fire.
- May re-ignite after fire is extinguished.
- Runoff may create fire or explosion hazard.
- Containers may explode when heated.
Chemical Identity & Physical Properties
| Also known as | nitrocellulose plasticscellulose nitrate plasticspyroxylin plasticscelluloid-type materials |
| Appearance | Solid plastic material, color varies by formulation. Nitrocellulose-based plastics are combustible solids that may self-heat in contact with air or moisture, often with a characteristic camphor-like odor in older formulations. |
| Flash Point | Not applicable (self-heating solid) |
| Boiling Point | Not applicable (decomposes before boiling) |
| Vapor Density | Not applicable (solid) |
| Water Reactivity | May ignite on contact with moisture; avoid water application |
Chemical details are general reference only. Always verify with current SDS, ERG, and SOP/SOG.
Fireground Response Guidance — UN 2006
Extinguishing Media
Dry chemical, CO2, sand, or dry earth; avoid water-based agents due to moisture sensitivity
PPE Requirements
⚠️ Level C minimum with SCBA; full turnout gear for fire conditions; avoid direct contact as material may self-heat
Isolation & Evacuation
ERG 135: isolate spill area minimum 25m in all directions; if material is on fire or involved in fire, isolate 800m in all directions and consider evacuation
Always confirm protective actions with the current edition of the Emergency Response Guidebook (ERG Guide 135).
First Actions for a UN 2006 Incident
- CALL 911. Then call emergency response telephone number on shipping paper. If shipping paper
- Stay upwind, uphill and/or upstream.
- Keep unauthorized personnel away.
- Isolate spill or leak area in all directions for at least 50 meters (150 feet) for liquids and at least 25 meters
- For highlighted materials: see Table 1 - Initial Isolation and Protective Action Distances.
- For non-highlighted materials: increase the immediate precautionary measure distance, in the downwind
