UN 2567 — Sodium pentachlorophenate
Placard: Toxic. ERG Guide 154. Training/quick-reference only — use current ERG + SOP/SOG for incident-specific actions.
Sodium pentachlorophenate is a toxic solid shipped as UN 2567. Dust exposure, skin contact and contaminated runoff are the main response concerns.
Hazard overview: Dust or solutions can injure by inhalation, ingestion or skin contact. Fire can produce toxic chlorinated fumes, and runoff can create a significant environmental hazard.
Response guidance: Avoid dust generation, isolate the area and contain runoff. Use water spray, dry chemical, CO2 or foam according to the fire conditions and SDS, while preventing contaminated water from spreading.
Firefighter training notes: Train crews on toxic dust control, decon and environmental containment. Avoid dry sweeping or actions that disperse powder.
Regulatory context: UN 2567 is transported as Sodium pentachlorophenate, Class 6 toxic material. Verify exact product and emergency information from shipping papers.
Storage & handling: Store closed and dry in a toxic-material area away from acids, oxidizers, heat and drains. Provide spill containment.
