Chemical & Response Details
| Also known as | Sodium aluminateAluminate de sodiumSodium aluminum oxideSoda aluminate |
| CAS Number | 1302-42-7 |
| Appearance | Clear to slightly cloudy liquid, typically colorless to pale yellow. Alkaline odor may be present. Aqueous solution is strongly alkaline and corrosive. |
| Flash Point | Not applicable (non-flammable aqueous solution) |
| Boiling Point | Approximately 100C (212F), similar to water depending on concentration |
| Vapor Density | Not applicable (aqueous solution) |
| Water Reactivity | Miscible with water; solution is highly alkaline and corrosive but does not react violently with water |
| Extinguishing | Water spray, fog, or foam may be used for fire involving surrounding materials; avoid direct contact with substance |
| PPE | ⚠️ Level B minimum; chemical-resistant suit, gloves, and boots required; SCBA or supplied-air respirator; face shield and eye protection mandatory due to corrosive nature |
| Isolation | ERG 154: Small spill isolate 30m all directions; large spill isolate 150m all directions, consider evacuation 300m downwind if material involved in fire |
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
