UN 1470
Class: 5
Placard type: Oxidizer
ERG: Guide 141 (check current ERG)
Isolation: ERG 141: Small spill isolate 50m; large spill isolate 100m initial, then evacuate 800m downwind if fire involves this material.
Chemical & Response Details
| Also known as | Lead(II) perchloratePerchloric acid lead(2+) saltLead diperchloratePlumbous perchlorate |
| CAS Number | 13637-76-8 |
| Appearance | White to colorless crystalline solid. Odorless. Deliquescent (absorbs moisture from air). |
| Flash Point | Not applicable (oxidizer) |
| Boiling Point | Decomposes before boiling |
| Vapor Density | Not applicable (solid) |
| Water Reactivity | Soluble in water (exothermic); forms acidic solution. No violent reaction but increases fire/explosion risk if contaminated. |
| Extinguishing | Water spray, dry chemical. Avoid organic materials and fuels near oxidizer. |
| PPE | ⚠️ Level B minimum with SCBA. Chemical-resistant suit if large spill. Leather and organic materials prohibited due to oxidizer sensitivity. |
| Isolation | ERG 141: Small spill isolate 50m; large spill isolate 100m initial, then evacuate 800m downwind if fire involves this material. |
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.
- May explode from heat or contamination.
- Some may burn rapidly.
- 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.
- Toxic by ingestion.
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).
