UN 2876 — Resorcinol
Placard: Toxic. ERG Guide 153. Training/quick-reference only — use current ERG + SOP/SOG for incident-specific actions.
UN 2876 is Resorcinol, a toxic phenolic solid assigned to ERG Guide 153. Dust, molten burns and phenolic fire smoke are key hazards.
Hazard overview: TOXIC phenolic solid; inhalation, ingestion or skin absorption may cause injury. Molten resorcinol can cause thermal and chemical burns. Combustible solid: may burn but does not ignite readily.
Response guidance: For UN 2876, isolate the area, avoid skin contact and use SCBA where dust, vapor, aerosol or fire is present. Contain toxic runoff and verify controls with SDS and ERG 153.
Firefighter training notes: Training for UN 2876 should emphasize exposure routes, SCBA use, vapor/dust monitoring, decontamination, runoff containment and SDS/package verification. Use ERG 153, SDS and local SOP.
Regulatory context: Resorcinol is regulated as a hazardous material for transport and emergency response. Storage, reporting, exposure, waste and incident-notification duties depend on package type, quantity, formulation and jurisdiction; verify shipping papers, SDS or authority guidance.
Storage & handling: Resorcinol should be stored in tightly closed compatible containers with ventilation, secondary containment, restricted access and SDS-based segregation from incompatible materials.

PPE Requirements
Use positive-pressure SCBA for vapor, dust, mist, fire or confined-space exposure. Wear chemical-resistant gloves, boots, eye/face protection and protective clothing.
Isolation & Evacuation
First Actions for a UN 2876 Incident
- Call 911 and the emergency response number on the shipping paper, if available.
- Keep unauthorized personnel away and establish incident command.
- Stay upwind, uphill and upstream.
- Avoid breathing vapor, dust, gas, mist, smoke or aerosols and avoid skin or eye contact.
- Do not touch damaged containers or spilled material without proper training and PPE.
- Prevent contaminated liquid, dust, runoff and decontamination waste from spreading.
- Ventilate confined spaces only after monitoring and only if properly trained and equipped.
- Use ERG Guide 153, SDS, shipping papers and monitoring to set isolation, evacuation and entry decisions.
