UN 1445 — Barium chlorate, solid
Placard: Oxidizer. ERG Guide 141. Training/quick-reference only — use current ERG + SOP/SOG for incident-specific actions.
Barium chlorate, solid is a white to yellowish crystalline solid or powder that is odorless and appears as colorless crystals or white granular material at room temperature. It is used in various industrial applications, including as a component in fireworks and flares.
Hazard overview: Barium chlorate, solid will accelerate burning when involved in a fire and may explode from heat or contamination. It can also oxidize and release heat when dissolved in water.
Response guidance: In the event of a fire, use dry chemical, CO2, or dry sand to extinguish the flames, and avoid using water as it may cause the substance to oxidize and release heat. If the substance is spilled, isolate the area and evacuate the surrounding area if necessary.
