UN 2717 — Camphor, synthetic
Placard: Flammable Solid. ERG Guide 133. Training/quick-reference only — use current ERG + SOP/SOG for incident-specific actions.
UN 2717 At a Glance
UN 2717 (Camphor, synthetic) is listed as DOT Class 4 Flammable Solid and is assigned to ERG Guide 133. Use this page to review placard data, common hazards, PPE notes, isolation context, first actions, and related UN numbers.
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.
