UN 2717 — Camphor, synthetic
Placard: Flammable Solid. ERG Guide 133. Training/quick-reference only — use current ERG + SOP/SOG for incident-specific actions.
Synthetic camphor is a flammable crystalline solid with a strong aromatic odor. It can sublime and produce ignitable vapor near heat sources.
Hazard overview: Camphor, synthetic is a flammable solid. Dust or finely divided product can ignite more easily, and fire smoke may irritate responders.
Response guidance: Keep ignition sources away, avoid dust generation and isolate the spill. Use Dry chemical, CO2, water spray or foam suitable for Class B fires from a safe position and cool exposed containers.
Firefighter training notes: Train crews to identify Camphor, synthetic by UN number, placard, ERG guide and SDS before choosing entry, isolation or extinguishment tactics.
Regulatory context: Use UN 2717, ERG 133, SDS, container labels and shipping papers to confirm the exact hazard profile and protective action distances.
Storage & handling: Store in closed, compatible containers away from heat, ignition sources and incompatible materials; keep the area ventilated and protected from damage.

Isolation & Evacuation
First Actions for a UN 2717 Incident
- Call 911 and the emergency response number shown on shipping papers or container documents.
- Keep unauthorized personnel away and establish an initial isolation perimeter.
- Stay upwind, uphill and upstream; avoid low areas where vapors or runoff may collect.
- Avoid breathing vapors, dust, smoke or mist and prevent skin and eye contact.
- Do not touch damaged containers or spilled material without appropriate chemical PPE.
- Ventilate confined spaces only when personnel are trained, monitored and properly equipped.
- Use ERG guidance, SDS, shipping papers and air monitoring before committing crews.
