UN 1494 — Sodium bromate

Placard: Oxidizer. ERG Guide 140. 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.

Sodium bromate is a white to off-white crystalline powder or granular solid that is stable at room temperature but decomposes when heated. It is used as a catalyst in various industrial processes.

Hazard overview: Sodium bromate can accelerate burning when involved in a fire, and some may decompose explosively when heated or involved in a fire. It is also highly reactive and can cause violent reactions when mixed with certain substances.

Response guidance: In the event of a fire, use water spray and dry chemical to extinguish, but avoid using combustible materials or organic matter. If the substance is spilled, wear Level B minimum personal protective equipment, including a SCBA and chemical-resistant suit.

Fireground Response Guidance — UN 1494

Extinguishing Media

Water spray, dry chemical; DO NOT use combustible materials or organic matter

PPE Requirements

⚠️ Level B minimum; SCBA required; chemical-resistant suit for fire or large spills

Wear Level B minimum personal protective equipment, including a SCBA and chemical-resistant suit, when handling sodium bromate.

Isolation & Evacuation

ERG 140: isolate 25-50m initially, evacuate 500m downwind if tank/railcar involved in fire
Always confirm protective actions with the current edition of the Emergency Response Guidebook (ERG Guide 140).

First Actions for a UN 1494 Incident

  • 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
  • Consider initial downwind evacuation for at least 100 meters (330 feet).
