UN 1318 — Cobalt resinate, precipitated
Placard: Flammable Solid. ERG Guide 133. Training/quick-reference only — use current ERG + SOP/SOG for incident-specific actions.
UN 1318 is Cobalt resinate, precipitated, a Class 4 flammable solid assigned to ERG Guide 133. It may burn as powder, granules, lumps or molten material depending on the exact product and fire conditions.
Hazard overview: UN 1318 presents flammable solid, dust and smoke hazards. Powders can burn rapidly or form dust-air mixtures, while fire may produce irritating smoke and contaminated residue.
Response guidance: For a UN 1318 incident, responders should confirm the product using shipping papers, container markings, SDS and ERG Guide 133. Establish incident command, isolate the area, stay upwind and uphill, remove ignition sources when safe, keep vapors, dust or runoff out of drains where relevant, and use compatible fire-control agents from a protected position.
Firefighter training notes: Training for UN 1318 should emphasize dust fire behavior, rapid surface burning, smoke exposure, compatible extinguishment and avoiding dust cloud generation. Use ERG 133, SDS and local SOP.
Regulatory context: Cobalt resinate, precipitated is regulated as a hazardous material for transportation and emergency response purposes. Transportation, workplace exposure, spill reporting, waste handling, storage and environmental requirements may vary by formulation, quantity and jurisdiction. Verify current requirements through shipping papers, SDS, facility documents and applicable DOT, OSHA, EPA, NFPA, state or local authority guidance.
Storage & handling: Cobalt resinate, precipitated should be stored in compatible containers in a cool, dry, well-ventilated area away from heat, sparks, open flames, oxidizers and incompatible materials. Prevent dust release, friction, impact and unauthorized access.

PPE Requirements
Use SCBA for fire, smoke, dust or confined-space exposure. Gloves, eye protection and protective clothing should be selected from SDS; avoid dust generation and contaminated residue contact.
Isolation & Evacuation
First Actions for a UN 1318 Incident
- CALL 911. Then call the emergency response telephone number on the shipping paper, if available.
- Keep unauthorized personnel away.
- Stay upwind, uphill and/or upstream.
- Eliminate ignition sources if it is safe to do so.
- Avoid creating dust clouds or spreading powder during movement or cleanup.
- Ventilate closed spaces before entering, but only if properly trained, equipped and authorized by incident command.
- Isolate the spill or fire area and expand the perimeter if large quantities, dust clouds or fire involvement are present.
- Use ERG Guide 133, shipping papers, SDS and incident command for protective actions and entry decisions.
