UN 2018 — Chloroanilines, solid

Placard: Toxic. ERG Guide 152. Training/quick-reference only — use current ERG + SOP/SOG for incident-specific actions.

🚒☣️
⚠️ 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 2018 is Chloroanilines, solid, 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 2018 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 2018 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, solid 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, solid 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.

Fireground Response Guidance — UN 2018

Extinguishing Media

Use dry chemical, CO2, foam or water spray as compatible with the product and fire size. Cool containers from a protected position and contain runoff as toxic contamination.

PPE Requirements

⚠️ Level B minimum; SCBA required; chemical-resistant suit mandatory to prevent skin absorption

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

ERG 152: isolate spill 25m all directions; if tank/rail car involved in fire, isolate 800m all directions
Always confirm protective actions with the current edition of the Emergency Response Guidebook (ERG Guide 152).

First Actions for a UN 2018 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.
