UN 1353
Class: 4
Placard type: Flammable Solid
ERG: Guide 133 (check current ERG)

Chemical & Response Details
| Also known as | Nitrocellulose-impregnated fabricsNitrated fabricCellulose nitrate fabricPyroxylin-treated fabric |
| Appearance | Fabric material impregnated with nitrocellulose solution, typically off-white to yellowish in color. Solid material at room temperature with variable texture depending on fabric type. |
| Flash Point | Varies by nitrocellulose content, typically 12-21C (54-70F) |
| Boiling Point | Not applicable (solid fabric material that decomposes) |
| Vapor Density | Not applicable (solid material) |
| Water Reactivity | No significant reaction with water, but water may reduce flammability |
| Extinguishing | Water spray, fog, or regular foam; dry chemical; CO2 |
| PPE | ⚠️ Level B minimum for fire response; structural firefighter turnout gear with SCBA for fire situations; avoid friction and static discharge |
| Isolation | ERG 133: isolate spill or leak area immediately for at least 50m in all directions; if fire, isolate 800m in all directions and consider initial evacuation for 800m |
Chemical details are general reference only. Always verify with current SDS, ERG, and SOP/SOG.
Common hazards (high level)
- Flammable/combustible material.
- May be ignited by friction, heat, sparks or flames.
- Some may burn rapidly with flare-burning effect.
- Powders, dusts, shavings, borings, turnings or cuttings may explode or burn with explosive violence.
- Substance may be transported in a molten form at a temperature that may be above its flash point.
- May re-ignite after fire is extinguished.
- Fire may produce irritating and/or toxic gases.
- Contact may cause burns to skin and eyes.
First actions (field-minded)
- CALL 911. Then call emergency response telephone number on shipping paper. If shipping paper
- Keep unauthorized personnel away.
- Stay upwind, uphill and/or upstream.
- Isolate spill or leak area for at least 25 meters (75 feet) in all directions.
- Consider initial downwind evacuation for at least 100 meters (330 feet).
