Chemical & Response Details
| Also known as | Ketone liquid mixturesKetone solutionsAliphatic ketonesMethyl ketonesMixed ketones |
| Appearance | Clear to pale yellow liquid with characteristic sweet, fruity, or acetone-like odor. Volatile organic solvent mixture at room temperature. |
| Flash Point | Varies by composition, typically -20°C to 23°C (-4°F to 73°F), highly flammable |
| Boiling Point | Varies by composition, typically 50°C to 150°C (122°F to 302°F) |
| Vapor Density | 2-4 (heavier than air, varies by specific ketone composition) |
| Water Reactivity | No significant reaction with water; may be partially water-miscible depending on specific ketones present |
| Extinguishing | Alcohol-resistant (AR-AFFF) foam preferred, CO2, dry chemical; water spray for cooling only |
| PPE | ⚠️ Level B minimum with SCBA required in enclosed areas or high vapor concentrations; chemical-resistant gloves and splash protection |
| Isolation | ERG 127: Initial isolation 50m in all directions; if tank/rail/tank truck involved in fire, isolate 800m and consider evacuation in that radius |
Chemical details are general reference only. Always verify with current SDS, ERG, and SOP/SOG.
Common hazards (high level)
- HIGHLY FLAMMABLE: Will be easily ignited by heat, sparks or flames.
- Vapors may form explosive mixtures with air.
- Vapors may travel to source of ignition and flash back.
- Most vapors are heavier than air. They will spread along the ground and collect in low or confined areas
- Vapor explosion hazard indoors, outdoors or in sewers.
- Those substances designated with a (P) may polymerize explosively when heated or involved in a fire.
- Runoff to sewer may create fire or explosion hazard.
- Containers may explode when heated.
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 for at least 50 meters (150 feet) in all directions.
- Consider initial downwind evacuation for at least 300 meters (1000 feet).
