UN 2018 — Chloroanilines, solid
Placard: Toxic. ERG Guide 152. Training/quick-reference only — use current ERG + SOP/SOG for incident-specific actions.
Chloroanilines, solid is a highly toxic substance that can cause severe injury or death if not handled properly. It is essential to take immediate action in case of an emergency.
Hazard overview: Highly toxic, may be fatal if inhaled, ingested or absorbed through skin. Contact with molten substance may cause severe burns to skin and eyes.
Response guidance: Use SCBA, chemical-resistant suit, and evacuate 25m radius. If tank or rail car is involved in fire, isolate 800m in all directions.

Isolation & Evacuation
First Actions for a UN 2018 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
