UN 2719 — Barium bromate
Placard: Oxidizer. ERG Guide 141. Training/quick-reference only — use current ERG + SOP/SOG for incident-specific actions.
Barium bromate is a toxic oxidizing solid. It is not fuel, but it can make combustible material burn more intensely.
Hazard overview: Barium bromate is an oxidizing solid. The main fire problem is intensification of burning when it contacts fuels or combustible contamination.
Response guidance: Remove combustibles from the area, keep contaminated runoff contained and cool exposed containers from a protected location. Do not let product mix with oils, fuels or organics.
Firefighter training notes: Train crews to identify Barium bromate by UN number, placard, ERG guide and SDS before choosing entry, isolation or extinguishment tactics.
Regulatory context: Use UN 2719, ERG 141, SDS, container labels and shipping papers to confirm the exact hazard profile and protective action distances.
Storage & handling: Store in closed, compatible containers away from heat, ignition sources and incompatible materials; keep the area ventilated and protected from damage.
UN 2719 Quick Details
Common Hazards of UN 2719
- Oxidizer; it can intensify fire even though the material itself is not fuel.
- Contact with combustibles, organics, oils, fuels or reducing agents may cause ignition or rapid burning.
- Fire may produce irritating and toxic fumes.
- Dust or solution contact may irritate skin, eyes and respiratory tract.
- Runoff can carry toxic metal or oxidizing contamination into waterways.
- Containers exposed to heat may rupture.
- Contamination can make the material unstable or more reactive.

PPE Requirements
Use SCBA for fire or dust conditions with chemical-resistant gloves, eye protection and protective clothing.
Isolation & Evacuation
First Actions for a UN 2719 Incident
- Call 911 and the emergency response number shown on shipping papers or container documents.
- Keep unauthorized personnel away and establish an initial isolation perimeter.
- Stay upwind, uphill and upstream; avoid low areas where vapors or runoff may collect.
- Avoid breathing vapors, dust, smoke or mist and prevent skin and eye contact.
- Keep combustibles, fuels, organic material, oils and reducing agents away from the release area.
- Do not touch damaged containers or spilled material without appropriate chemical PPE.
- Ventilate confined spaces only when personnel are trained, monitored and properly equipped.
- Use ERG guidance, SDS, shipping papers and air monitoring before committing crews.
