UN 2513 — Bromoacetyl bromide

Placard: Corrosive. ERG Guide 156. 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 2513 is Bromoacetyl bromide, a toxic corrosive acid bromide assigned to ERG Guide 156. Moisture can release hydrogen bromide fumes and heat.

Hazard overview: TOXIC and CORROSIVE acid bromide liquid; vapor or liquid contact can severely burn eyes, skin and lungs. Reacts violently with water or moist air, releasing hydrogen bromide fumes and heat. Lachrymatory vapors can cause intense eye and respiratory irritation.

Response guidance: For UN 2513, isolate the spill or leak, stay upwind and use SCBA with chemical protection. Control moisture contact, contain acidic runoff and use compatible dry media or protected cylinder cooling under ERG 156.

Firefighter training notes: Training for UN 2513 should emphasize water-reactive corrosive fuming, dry-agent selection, SCBA/Level A decisions, decontamination and acidic runoff control. Use ERG 156, SDS and local SOP.

Regulatory context: Bromoacetyl bromide is regulated as a hazardous material for transport and emergency response. Storage, exposure, spill reporting, waste and fire-code duties depend on quantity, concentration and jurisdiction; verify shipping papers, SDS and local authority requirements.

Storage & handling: Bromoacetyl bromide should be stored dry in tightly closed compatible containers away from water, moisture, bases, oxidizers/reducing agents where incompatible, heat and unauthorized access. Provide secondary containment.

Fireground Response Guidance — UN 2513

Extinguishing Media

Use dry chemical, CO2, dry sand or SDS-approved dry media. Water spray may cool exposed containers from a protected distance, but direct water can increase fuming or reaction.

PPE Requirements

⚠️ Level B minimum required; full-face SCBA and chemical-resistant suit mandatory. Material is highly corrosive and lachrymatory.

Use positive-pressure SCBA and chemical-resistant protective clothing. Level A may be needed for heavy fuming, splash risk, liquefied gas contact or unknown concentrations.

Isolation & Evacuation

ERG 156: Initial isolation 50m in all directions. Protective action distance: 0.1km (day) to 0.3km (night) for small spills. Larger spills require greater distances.
Always confirm protective actions with the current edition of the Emergency Response Guidebook (ERG Guide 156).

First Actions for a UN 2513 Incident

  • Call 911 and the emergency response number on the shipping paper, if available.
  • Keep unauthorized personnel away and establish incident command.
  • Stay upwind, uphill and upstream.
  • Avoid breathing vapor, dust, mist, smoke or fumes and avoid skin or eye contact.
  • Keep water contact controlled because moisture can increase heat release or corrosive fuming.
  • Do not touch damaged containers or spilled material without proper training and PPE.
  • Ventilate confined spaces only after monitoring and only if properly trained and equipped.
  • Use ERG Guide 156, SDS, shipping papers and monitoring to set isolation, evacuation and entry decisions.
