Chemical & Response Details
| Also known as | Insecticide gas n.o.s.Flammable insecticide aerosolPesticide gas flammableFumigant gas flammable |
| Appearance | Compressed or liquefied gas, typically colorless to pale yellow with a characteristic chemical or solvent-like odor. May be under pressure in cylinders or aerosol containers. |
| Flash Point | Not applicable (flammable gas) |
| Boiling Point | Not applicable (varies by formulation) |
| Vapor Density | Heavier than air (typically >1) |
| Water Reactivity | No significant reaction with water, though may have limited solubility |
| Extinguishing | CO2, dry chemical, water spray for cooling containers only; do not extinguish leak fire unless leak can be stopped |
| PPE | ⚠️ Level B minimum with SCBA required; gas-tight chemical protective clothing if contact with liquefied gas possible; thermal protection if fire involved |
| Isolation | ERG 115: Initial isolation 100m in all directions; Protective action distance up to 800m downwind for large spills during day |
Chemical details are general reference only. Always verify with current SDS, ERG, and SOP/SOG.
Common hazards (high level)
- EXTREMELY FLAMMABLE.
- Will be easily ignited by heat, sparks or flames.
- Will form explosive mixtures with air.
- Vapors from liquefied gas are initially heavier than air and spread along ground.
- Vapors may travel to source of ignition and flash back.
- Cylinders exposed to fire may vent and release flammable gas through pressure relief devices.
- Containers may explode when heated.
- Ruptured cylinders may rocket.
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.
- Many gases are heavier than air and will spread along the ground and collect in low or confined areas
- Isolate spill or leak area for at least 100 meters (330 feet) in all directions.
- Consider initial downwind evacuation for at least 800 meters (1/2 mile).
