Chemical & Response Details
| Also known as | Cellulose nitrate scrapNitrocellulose scrapPyroxylin scrapCelluloid waste |
| Appearance | Solid material, typically appearing as colorless to pale yellow or amber pieces, chips, or fragments. May have a characteristic camphor-like odor. Highly flammable plastic-like material. |
| Flash Point | Not applicable (spontaneously flammable solid) |
| Boiling Point | Not applicable (decomposes before boiling) |
| Vapor Density | Not applicable (solid) |
| Water Reactivity | May ignite on contact with moisture or moist air; water may increase reactivity and ignition risk |
| Extinguishing | Dry chemical, sand, dry earth; avoid water streams which may spread burning material |
| PPE | ⚠️ Level B minimum with SCBA; full protective clothing required; material can ignite spontaneously |
| Isolation | ERG 135: isolate spill/leak area immediately 25-50m all directions; if tank/rail car involved in fire isolate 800m all directions |
Chemical details are general reference only. Always verify with current SDS, ERG, and SOP/SOG.
Common hazards (high level)
- 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.
First actions (field-minded)
- 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
