UN 3360
Class: 4
Placard type: Flammable Solid
ERG: Guide 133 (check current ERG)

Chemical & Response Details
| Also known as | Dried plant fibersAgricultural fibersNatural fibersVegetable matter driedPlant-based fibersSisalJuteHemp fibersCotton lintersFlax fibers |
| Appearance | Tan to brown fibrous material in various forms (bales, loose, compressed). Dry, combustible organic matter with no distinctive odor when not burning. |
| Flash Point | Variable, typically ignites at 200-250°C (392-482°F) depending on fiber type and moisture content |
| Boiling Point | Not applicable (solid material that decomposes/burns rather than boils) |
| Vapor Density | Not applicable (solid material with no significant vapor pressure) |
| Water Reactivity | No significant reaction; water may be used to wet down and prevent ignition or suppress fire |
| Extinguishing | Water fog, water spray, foam, dry chemical, CO2; foam may be used for fire suppression |
| PPE | ⚠️ Structural firefighters' protective clothing and SCBA for fire situations; dust mask for handling to prevent inhalation of particulates |
| Isolation | ERG 133: Small spill isolate 30m all directions; large spill 100m; fire isolate 800m and consider evacuation for 800m in all directions if tank/railcar involved |
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).
