UN 2513 Quick Details
UN 2513
Product name: Bromoacetyl bromide
DOT Class: 8
Placard type: Corrosive
ERG Guide: 156 (check current ERG)
Initial isolation: 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.
Common Hazards of UN 2513
- Combustible material: may burn but does not ignite readily.
- Substance will react with water (some violently) releasing flammable, toxic or corrosive gases and runoff.
- When heated, vapors may form explosive mixtures with air: indoors, outdoors and sewers explosion
- Most vapors are heavier than air. They will spread along the ground and collect in low or confined areas
- Vapors may travel to source of ignition and flash back.
- Corrosives in contact with metals may evolve flammable hydrogen gas.
- Containers may explode when heated or if contaminated with water.
- TOXIC and/or CORROSIVE; inhalation, ingestion or contact (skin, eyes) with vapors, dusts or substance
Chemical Identity & Physical Properties
| Also known as | Bromoacetyl bromideα-Bromoacetyl bromideBromoacetic acid bromideAcetyl bromide, bromo-BAB |
| CAS Number | 598-21-0 |
| Appearance | Clear to pale yellow liquid with a pungent, irritating odor. Corrosive and lachrymatory (tear-producing). Liquid at room temperature. |
| Flash Point | Not applicable (reacts with moisture, generates heat) |
| Boiling Point | 148-150°C (298-302°F) |
| Vapor Density | 4.5 (heavier than air) |
| Water Reactivity | Reacts violently with water, releasing toxic and corrosive hydrogen bromide (HBr) gas. Do not use water directly on material. |
Chemical details are general reference only. Always verify with current SDS, ERG, and SOP/SOG.
Fireground Response Guidance — UN 2513
Extinguishing Media
Dry chemical, CO2, dry sand. Avoid water-based agents. Use alcohol-resistant foam at a distance if necessary.
PPE Requirements
⚠️ Level B minimum required; full-face SCBA and chemical-resistant suit mandatory. Material is highly corrosive and lachrymatory.
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. Then call emergency response telephone number on shipping paper. If shipping paper
- Keep unauthorized personnel away.
- Stay upwind, uphill and/or upstream.
- Ventilate closed spaces before entering, but only if properly trained and equipped.
- Isolate spill or leak area in all directions for at least 50 meters (150 feet) for liquids and at least 25 meters
- For highlighted materials: see Table 1 - Initial Isolation and Protective Action Distances.
- For non-highlighted materials: increase the immediate precautionary measure distance, in the downwind
