Placard: Miscellaneous. ERG Guide 171. Training/quick-reference only — use current ERG + SOP/SOG for incident-specific actions.
🚒☣️
⚠️ This page is a quick-reference aid. For real incidents: stage upwind, isolate, deny entry, request Hazmat early, and consult the current ERG + SOP/SOG.
UN 3314 covers plastics moulding compound, typically pellets, granules, powders, or resin materials. The hazard is usually low unless the material is heated, burning, or mixed with hazardous additives.
Hazard overview: The material may burn but does not ignite readily under normal handling. Burning or overheated plastics can produce irritating or toxic smoke and may create slip hazards if pellets spill.
Response guidance: Control spilled pellets or granules, keep them out of drains, and use standard extinguishing media for surrounding fire. Use SCBA if the compound is heated, burning, or producing fumes.

Isolation & Evacuation
ERG 171: No evacuation distances specified for small spills; if heated or burning, isolate 25m in all directions and consider evacuation of immediate area
Always confirm protective actions with the current edition of the Emergency Response Guidebook (ERG Guide 171).
First Actions for a UN 3314 Incident
- Keep unauthorized personnel away.
- Stay upwind, uphill and/or upstream.
- Isolate spill or leak area in all directions for at least 50 meters (150 feet) for liquids and at least 25 meters
- For highlighted materials: see Table 1 - Initial Isolation and Protective Action Distances.
- For non-highlighted materials: increase the immediate precautionary measure distance, in the downwind
