🚒☣️
⚠️ 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.
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.
