UN 2872 — Dibromochloropropanes
Placard: Toxic. ERG Guide 159. Training/quick-reference only — use current ERG + SOP/SOG for incident-specific actions.
Dibromochloropropanes is an isomer/category shipping name for toxic halogenated propanes. Response should avoid assuming a single CAS-specific behavior and should verify the exact product.
Hazard overview: The key hazards are toxic vapor, skin absorption or contact, and corrosive halogen acid gases in fire. Because isomers can vary, the SDS is required for definitive guidance.
Response guidance: Isolate the spill, prevent entry to drains, and keep personnel out of vapor areas unless equipped with SCBA and chemical protection. Use foam, dry chemical, or CO2 as appropriate for fire exposure.
Firefighter training notes: Training should cover toxic dust/vapor control, decontamination, runoff containment, respiratory protection, and SDS-based exposure precautions for UN 2872.
Regulatory context: Confirm the exact shipping description, hazard class, packaging, SDS, and ERG 159; disposal and cleanup may require hazardous-waste controls.
Storage & handling: Store tightly closed in a dry, labeled area away from food, incompatible materials, and conditions that could spread dust, vapor, or contaminated runoff.
UN 2872 Quick Details
Common Hazards of UN 2872
- Toxic halogenated liquid category; inhalation, ingestion, or skin absorption can cause serious injury.
- Vapors can irritate or damage respiratory tissues and may be heavier than air.
- Liquid contact can injure skin and eyes and contaminate clothing.
- Some isomers or formulations may burn, but they do not behave like simple gasoline-type liquids.
- Fire can produce hydrogen bromide, hydrogen chloride, and other toxic corrosive gases.
- Runoff can contaminate soil and waterways.
- Exact isomer or mixture must be verified through SDS and shipping papers.

PPE Requirements
Use SCBA with chemical-resistant suit, gloves, boots, and splash/face protection; Level A may be needed for unknown vapor concentrations.
Isolation & Evacuation
First Actions for a UN 2872 Incident
- Call 911 and the emergency response number shown on shipping papers or the SDS.
- Keep unauthorized personnel away and prevent dust, vapor, or runoff from spreading.
- Stay upwind, uphill, and upstream; avoid breathing dust, fumes, or fire gases.
- Avoid all skin and eye contact with powder, liquid, solutions, or contaminated clothing.
- Do not touch damaged containers or spilled material without chemical-resistant PPE.
- Control runoff and keep material out of drains, soil, and waterways.
- Use ERG guidance, SDS, shipping papers, and exposure monitoring before cleanup.
