UN 2019 — Chloroanilines, liquid
Placard: Toxic. ERG Guide 152. Training/quick-reference only — use current ERG + SOP/SOG for incident-specific actions.
UN 2019 is Chloroanilines, liquid, a highly toxic chloroaniline entry assigned to ERG Guide 152. Skin absorption and toxic fire products are key responder concerns.
Hazard overview: HIGHLY TOXIC chloroaniline material; may be fatal if inhaled, ingested or absorbed through skin. Skin absorption is a major concern; avoid all skin contact. Combustible material: may burn but does not ignite readily.
Response guidance: For a UN 2019 incident, verify the product with shipping papers, container markings, SDS and ERG Guide 152. Establish incident command, isolate the area, stay upwind, prevent incompatible contact, control runoff or dust spread and base entry/fire-control actions on monitoring and local SOP.
Firefighter training notes: Training for UN 2019 should emphasize toxic exposure routes, skin absorption, air monitoring, PPE selection, decontamination, runoff containment and ERG/SDS verification. Use ERG 152, SDS and local SOP.
Regulatory context: Chloroanilines, liquid is regulated as a hazardous material for transportation and emergency response purposes. Storage, workplace exposure, emergency planning, spill reporting, waste handling and environmental requirements vary by exact product, concentration, quantity and jurisdiction. Verify current requirements through shipping papers, SDS, container markings and applicable DOT, OSHA, EPA, NFPA, state or local authority guidance.
Storage & handling: Chloroanilines, liquid should be stored in tightly closed compatible containers in a secure toxic-material area with secondary containment, restricted access, ventilation and waste/decontamination planning according to SDS.

Chemical Identity & Physical Properties
Liquid mixture of chloroaniline isomers, typically colorless to pale yellow or amber colored with a characteristic amine-like odor. Combustible liquid at room temperature.
| 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 |

PPE Requirements
Use positive-pressure SCBA for dust, vapor, mist, fire or confined-space exposure. Wear chemical-resistant gloves, boots, eye/face protection and protective clothing selected from SDS; avoid skin contact.
Isolation & Evacuation
First Actions for a UN 2019 Incident
- CALL 911. Then call the emergency response telephone number on the shipping paper, if available.
- Keep unauthorized personnel away.
- Stay upwind, uphill and/or upstream.
- Avoid breathing dust, vapor, fumes, mist or smoke and avoid skin or eye contact.
- Do not touch damaged containers or spilled material unless properly trained and wearing appropriate protective equipment.
- Ventilate closed spaces before entering, but only if properly trained, equipped, monitored and authorized by incident command.
- Isolate the spill or release area and expand the perimeter for fire involvement, water reaction, vapor generation, dust spread or unknown product identity.
- Use ERG Guide 152, shipping papers, SDS, air monitoring and incident command for protective actions.
