Chemical & Response Details
| Also known as | Corrosive solid mixtureSolid corrosive n.o.s.Corrosive solid preparationSolid containing corrosive liquid NOS |
| Appearance | Variable appearance depending on specific formulation. Solid material impregnated with or containing corrosive liquid components. May be granular, powder, or formed solid. Corrosive properties derived from absorbed or encapsulated liquid phase. |
| Flash Point | Variable depending on specific components; refer to SDS for individual formulation |
| Boiling Point | Not applicable (solid mixture with liquid components) |
| Vapor Density | Not applicable (solid material; vapor properties vary by liquid component) |
| Water Reactivity | May react depending on corrosive component; contact may release corrosive liquids or fumes; use caution with water |
| Extinguishing | Generally avoid water and foam; use dry chemical, soda ash, lime, or sand for small fires; consult ERG 154 for specific guidance |
| PPE | ⚠️ Level B minimum recommended; full face SCBA required; chemical-resistant suit with boots and gloves; avoid all skin contact; eye protection mandatory |
| Isolation | ERG 154: isolate spill/leak area immediately for at least 25-50 meters in all directions; if tank/rail car involved in fire, isolate 800 meters in all directions and consider initial evacuation for 800 meters |
Chemical details are general reference only. Always verify with current SDS, ERG, and SOP/SOG.
Common hazards (high level)
- TOXIC and/or CORROSIVE; inhalation, ingestion or skin contact with material may cause severe injury
- Contact with molten substance may cause severe burns to skin and eyes.
- Avoid any skin contact.
- Fire may produce irritating, corrosive and/or toxic gases.
- Runoff from fire control or dilution water may be corrosive and/or toxic and cause environmental
- Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive
- Some are oxidizers and may ignite combustibles (wood, paper, oil, clothing, etc.).
- Corrosives in contact with metals may evolve flammable hydrogen gas.
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
- For highlighted materials: see Table 1 - Initial Isolation and Protective Action Distances.
- For non-highlighted materials: increase the immediate precautionary measure distance, in the downwind
