UN 2019
Class: 6
Placard type: Toxic
ERG: Guide 152 (check current ERG)
Isolation: ERG 152: isolate spill area immediate 50m all directions; if tank/rail car involved in fire isolate 800m all directions, evacuate 1600m downwind
Chemical & Response Details
| Also known as | chlorinated anilineschloroaniline isomersaminochlorobenzeneschlorophenylamine |
| Appearance | Liquid mixture of chloroaniline isomers, typically colorless to pale yellow or amber colored with a characteristic amine-like odor. Combustible liquid at room temperature. |
| Flash Point | 97-124C (207-255F) depending on isomer |
| Boiling Point | 208-232C (406-450F) depending on isomer |
| Vapor Density | 4.4 (heavier than air) |
| Water Reactivity | No significant reaction with water, but slightly soluble; avoid water contact due to environmental contamination concerns |
| Extinguishing | Alcohol-resistant foam, CO2, dry chemical; water spray for cooling only |
| PPE | ⚠️ Level A or B minimum; full face SCBA required; chemical-resistant suit mandatory due to severe skin absorption hazard and high toxicity |
| Isolation | ERG 152: isolate spill area immediate 50m all directions; if tank/rail car involved in fire isolate 800m all directions, evacuate 1600m downwind |
Chemical details are general reference only. Always verify with current SDS, ERG, and SOP/SOG.
Common hazards (high level)
- Highly toxic, may be fatal if inhaled, ingested or absorbed through skin.
- Contact with molten substance may cause severe burns to skin and eyes.
- Avoid any skin contact.
- Fire may produce irritating, corrosive and/or toxic gases.
- Runoff from fire control or dilution water may be corrosive and/or toxic and cause environmental
- Combustible material: may burn but does not ignite readily.
- Containers may explode when heated.
- Those substances designated with a (P) may polymerize explosively when heated or involved in a fire.
First actions (field-minded)
- CALL 911. Then call emergency response telephone number on shipping paper. If shipping paper
- 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
