UN 1495
Class: 5
Placard type: Oxidizer
ERG: Guide 140 (check current ERG)
Isolation: ERG 140: Isolate spill area at least 50m in all directions. For large spills, consider initial evacuation 100m. If fire involves this material, isolate 800m and evacuate 1600m downwind.
Chemical & Response Details
| Also known as | Chlorate de sodiumChloric acid sodium saltSoda chlorateAtlacideKusatol |
| CAS Number | 7775-09-9 |
| Appearance | Colorless or white crystalline solid, odorless. Hygroscopic (absorbs moisture from air). Deliquescent. |
| Flash Point | Not applicable (oxidizer, not combustible itself but accelerates combustion) |
| Boiling Point | Decomposes at approximately 300C (572F) |
| Vapor Density | Not applicable (solid) |
| Water Reactivity | Soluble in water (exothermic dissolution). Aqueous solutions are stable but contamination can cause violent reactions. |
| Extinguishing | Dry chemical, sand, or dry earth only. Do NOT use water streams directly on material. Flood with water from a distance if necessary. |
| PPE | ⚠️ Level B minimum for spills; SCBA and full protective clothing required. Avoid contamination of gear with organic materials or reducing agents. |
| Isolation | ERG 140: Isolate spill area at least 50m in all directions. For large spills, consider initial evacuation 100m. If fire involves this material, isolate 800m and evacuate 1600m downwind. |
Chemical details are general reference only. Always verify with current SDS, ERG, and SOP/SOG.
Common hazards (high level)
- These substances will accelerate burning when involved in a fire.
- Some may decompose explosively when heated or involved in a fire.
- May explode from heat or contamination.
- Some will react explosively with hydrocarbons (fuels).
- May ignite combustibles (wood, paper, oil, clothing, etc.).
- Containers may explode when heated.
- Runoff may create fire or explosion hazard.
- Inhalation, ingestion or contact (skin, eyes) with vapors or substance may cause severe injury, burns or
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
- Consider initial downwind evacuation for at least 100 meters (330 feet).
