UN 2000 — Celluloid, in block, rods, rolls, sheets, tubes, etc., except scrap
Placard: Flammable Solid. ERG Guide 133. Training/quick-reference only — use current ERG + SOP/SOG for incident-specific actions.
UN 2000 is Celluloid, in block, rods, rolls, sheets, tubes, etc., except scrap, a flammable celluloid solid assigned to ERG Guide 133. It can burn rapidly and may re-ignite if hot material remains.
Hazard overview: FLAMMABLE SOLID; celluloid can ignite readily by heat, sparks or flame. May burn very rapidly and intensely once ignited. Heating can produce flammable vapors and pressure buildup in packages.
Response guidance: For a UN 2000 incident, verify the product with shipping papers, container markings, SDS and ERG Guide 133. Establish incident command, isolate the area, stay upwind, control ignition or downwind hazards, cool exposed containers from a protected distance when appropriate and base entry decisions on monitoring and local SOP.
Firefighter training notes: Training for UN 2000 should emphasize fire behavior, exposure routes, air monitoring, PPE selection, evacuation, runoff control and ERG/SDS verification. Use ERG 133, SDS and local SOP.
Regulatory context: Celluloid, in block, rods, rolls, sheets, tubes, etc., except scrap is regulated as a hazardous material for transportation and emergency response purposes. Storage, workplace exposure, emergency planning, spill reporting and waste handling requirements vary by exact product, concentration, quantity and jurisdiction. Verify current requirements through shipping papers, SDS, container markings and applicable DOT, OSHA, EPA, NFPA, state or local authority guidance.
Storage & handling: Celluloid, in block, rods, rolls, sheets, tubes, etc., except scrap should be stored in a cool, dry, ventilated area away from heat, sparks, flames, oxidizers and incompatible materials. Limit accumulation and protect from friction, impact and dust generation where applicable.

PPE Requirements
Use structural firefighting PPE with SCBA for fire or smoke. For spill handling without fire, use gloves, eye protection and respiratory protection if dust or residues are present.
Isolation & Evacuation
First Actions for a UN 2000 Incident
- CALL 911. Then call the emergency response telephone number on the shipping paper, if available.
- Keep unauthorized personnel away.
- Stay upwind, uphill and/or upstream.
- Avoid breathing vapors, gas, smoke, mist or dust and avoid skin or eye contact.
- Avoid friction, sparks, heat and dust generation; watch for rapid burning or re-ignition.
- Do not touch damaged containers or spilled/released material unless properly trained and wearing appropriate protective equipment.
- Ventilate closed spaces before entering, but only if properly trained, equipped, monitored and authorized by incident command.
- Isolate the release or spill area and expand the perimeter for fire involvement, vapor accumulation, cylinder/tank heating or unknown product identity.
- Use ERG Guide 133, shipping papers, SDS, air monitoring and incident command for protective actions.
