Chemical & Response Details
| Also known as | Bromine liquidElemental bromineDibromineMolecular bromine |
| CAS Number | 7726-95-6 |
| Appearance | Heavy, dark reddish-brown fuming liquid with a sharp, pungent, irritating odor. Corrosive to most metals and organic materials. |
| Flash Point | Not applicable (non-flammable) |
| Boiling Point | 58.8C (137.8F) |
| Vapor Density | 5.5 (much heavier than air) |
| Water Reactivity | Slightly soluble in water; produces hypobromous acid. Avoid direct water contact as it increases vapor evolution. |
| Extinguishing | Do not use water directly. Use dry chemical or CO2 for small fires. Flooding amounts of water only for large fires from safe distance. |
| PPE | ⚠️ Level A required for Zone A materials; fully encapsulating chemical protective suit with SCBA; butyl rubber or Viton gloves; bromine vapor extremely toxic. |

Common hazards (high level)
- TOXIC and/or CORROSIVE; inhalation, ingestion or skin contact with material may cause severe injury
- Contact with molten substance may cause severe burns to skin and eyes.
- Avoid any skin contact.
- Fire may produce irritating, corrosive and/or toxic gases.
- Runoff from fire control or dilution water may be corrosive and/or toxic and cause environmental
- Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive
- Some are oxidizers and may ignite combustibles (wood, paper, oil, clothing, etc.).
- Corrosives in contact with metals may evolve flammable hydrogen gas.
First actions (field-minded)
- 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
