UN 3087 — Oxidizing solid, poisonous, n.o.s.
Placard: Oxidizer. ERG Guide 141. Training/quick-reference only — use current ERG + SOP/SOG for incident-specific actions.
UN 3087 is Oxidizing solid, poisonous, n.o.s., a broad toxic oxidizing solid assigned to ERG Guide 141. Toxic dust and oxidizer contamination require control.
Hazard overview: TOXIC and OXIDIZING solid, n.o.s.; inhalation, ingestion or skin contact may cause severe injury. Can intensify fire involving combustibles and incompatible materials. Contact with fuels, organics, oils or reducing agents may cause violent reaction or decomposition.
Response guidance: For UN 3087, isolate the area, keep combustibles/reducing agents away and identify the exact product. Use oxidizer-compatible tactics and contain runoff under ERG 141.
Firefighter training notes: Training for UN 3087 should emphasize product verification, incompatible media, dust control, SCBA use, runoff containment and escalation criteria. Use ERG 141, SDS and local SOP.
Regulatory context: Oxidizing solid, poisonous, n.o.s. is regulated as a hazardous material for transport and emergency response. Storage, reporting, exposure, waste and incident-notification duties depend on quantity, formulation and jurisdiction; verify shipping papers, SDS and authority guidance.
Storage & handling: Oxidizing solid, poisonous, n.o.s. should be stored in compatible oxidizer/corrosive-rated containers away from combustibles, organics, fuels, reducing agents, moisture-sensitive materials and contamination.

PPE Requirements
Use positive-pressure SCBA and chemical-resistant protective clothing. Level A or B may be needed for unknown product, heavy vapor/dust or splash risk.
Isolation & Evacuation
First Actions for a UN 3087 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 fumes 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 141, SDS, shipping papers and monitoring to set isolation, evacuation and entry decisions.
