🚒☣️
⚠️ 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.
Barium perchlorate, solid is a highly reactive substance that can accelerate burning when involved in a fire. It may also explode from heat or contamination.
Hazard overview: Barium perchlorate, solid can cause severe irritation to skin and eyes. It can also release toxic fumes when heated or contaminated.
Response guidance: In case of fire, use water only to extinguish. Do not use foam, dry chemical, CO2, or combustible materials.

Fireground Response Guidance — UN 1447
Extinguishing Media
Water only; do not use foam, dry chemical, CO2, or combustible materials on fires involving oxidizers
PPE Requirements
⚠️ Level B minimum; full chemical protective clothing with SCBA; avoid contact as it may cause severe irritation
Use Level B minimum personal protective equipment, including full chemical protective clothing with SCBA, to avoid contact with the substance.
Isolation & Evacuation
ERG 141: isolate 50m all directions initially; if fire involves large quantities, isolate 800m all directions and evacuate 1600m downwind
Always confirm protective actions with the current edition of the Emergency Response Guidebook (ERG Guide 141).
First Actions for a UN 1447 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).
