UN 2590 — Asbestos, chrysotile

Placard: Miscellaneous. ERG Guide 171. 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.

Asbestos, chrysotile is a fiber inhalation hazard. Emergency response should focus on preventing airborne fiber release and secondary contamination.

Hazard overview: The material does not behave like a typical chemical vapor hazard; the critical risk is respirable fiber dust. Disturbance, impact or fire-damaged packaging can spread contaminated debris.

Response guidance: Keep personnel away from dust, avoid dry sweeping and use wet methods or HEPA-controlled collection when trained and equipped. Establish decontamination for clothing, tools and runoff.

Firefighter training notes: Training should focus on asbestos fiber control, respiratory protection, wet methods, HEPA cleanup and contamination control rather than ordinary chemical spill tactics.

Regulatory context: UN 2590 is Asbestos, chrysotile, Class 9. Response and disposal must follow applicable asbestos handling, transport and environmental regulations.

Storage & handling: Keep packages sealed and protected from damage. Store away from traffic, abrasion and weather that could release fibers.

UN 2590
Product name: Asbestos, chrysotile
DOT Class: 9
Placard type: Miscellaneous
ERG Guide: 171 (check current ERG)
Initial isolation: ERG 171: No evacuation distances given; avoid creating dust; contain fibers; specialized cleanup required for carcinogenic material

Common Hazards of UN 2590

  • Chrysotile asbestos is a hazardous fiber-forming solid; inhalation of airborne fibers is the main exposure route.
  • Disturbance, breakage or dry handling can release respirable fibers.
  • Fire, demolition or impact can spread contaminated dust and debris.
  • Material is not readily combustible, but packaging or surrounding materials may burn.
  • Runoff or wash water can carry asbestos-containing debris and must be controlled.
  • Contaminated clothing and equipment can spread fibers beyond the hot zone.
  • Long-term health risks are associated with inhaled asbestos fibers.

Chemical Identity & Physical Properties

Chrysotile asbestos is a fibrous mineral material. It may be shipped as raw fiber, incorporated material or contaminated debris depending on the package.

Also known asChrysotile asbestosWhite asbestosSerpentine asbestosAsbestos fiber
CAS Number12001-29-5
AppearanceWhite to gray fibrous silicate mineral, odorless. Flexible fibers that can be woven; occurs as bundles of fibrils.
Flash PointNot applicable (non-combustible mineral)
Boiling PointNot applicable (decomposes at high temperature)
Vapor DensityNot applicable (solid)
Water ReactivityNo violent reaction with water; wetting is commonly used to reduce airborne fibers, but runoff must be managed as contaminated.
Chemical details are general reference only. Always verify with current SDS, ERG, and SOP/SOG.

Fireground Response Guidance — UN 2590

Extinguishing Media

Use water mist or wet methods to suppress fiber release when compatible with site controls; extinguish surrounding fires with appropriate agents.

PPE Requirements

⚠️ Respiratory protection suitable for asbestos fibers is required; use disposable or decontaminable protective clothing and avoid dry sweeping.

Use respiratory protection approved for asbestos fiber exposure and disposable or decontaminable protective clothing. Prevent fibers from leaving the controlled area.

Isolation & Evacuation

ERG 171: No evacuation distances given; avoid creating dust; contain fibers; specialized cleanup required for carcinogenic material
Always confirm protective actions with the current edition of the Emergency Response Guidebook (ERG Guide 171).

First Actions for a UN 2590 Incident

  • Call 911 and the emergency response number shown on shipping papers; confirm the material with ERG, SDS and container markings.
  • Keep unauthorized personnel away and establish hot, warm and cold zones before entry.
  • Stay upwind, uphill and upstream; avoid low areas where vapors, dust or runoff may collect.
  • Avoid breathing vapors, dust, mist or decomposition products and prevent skin or eye contact.
  • Do not touch damaged packages or containers unless properly trained and wearing suitable chemical PPE.
  • Ventilate confined spaces only after atmospheric monitoring and only with trained, equipped personnel.
  • Use ERG Guide 171, SDS, shipping papers and monitoring results for isolation, PPE and fire-control decisions.

Frequently Asked Questions about UN 2590

Inhalation of airborne asbestos fibers is the primary hazard.

The asbestos itself is not readily combustible, but packaging or surrounding materials may burn.

Dry sweeping can put respirable fibers into the air and spread contamination.

Wet methods can help suppress fibers, but runoff and wet debris must be handled as contaminated material.

Use asbestos-appropriate respiratory protection and protective clothing that can be disposed of or decontaminated.
