UN 3315 — Chemical sample, poisonous
Placard: Toxic. ERG Guide 151. Training/quick-reference only — use current ERG + SOP/SOG for incident-specific actions.
🚒☣️
⚠️ Verification required:
Broad or variable material category; verify exact product, SDS and shipping papers.
⚠️ 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 3315 covers poisonous chemical samples where the exact physical and chemical properties may vary. Responders should treat the sample as a highly toxic unknown until labels, paperwork, or lab information confirm identity.
Hazard overview: The sample may be fatal if inhaled, ingested, or absorbed through skin. Fire or container damage may release toxic or corrosive decomposition products depending on the sample.
Response guidance: Isolate the package, avoid contact, and use dry chemical or CO2 if the chemical identity is unknown. Confirm the sample through shipping papers, container labels, and SDS before applying water or other agents.

Always confirm protective actions with the current edition of the Emergency Response Guidebook (ERG Guide 151).
First Actions for a UN 3315 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
