Acrolein flammability limits

Flammability Acrolein is very flammable its flash point is <0° C, but a toxic vapor cloud will develop before a flammable one. The flammable limits in air are 2.8% and 31.0% lower and upper explosive limits, respectively by volume. Acrolein is only partly soluble in water and will cause a floating fire, so alcohol type foam should be used in firefighting. The vapors are heavier than air and can travel along the ground and flash back from an ignition source. 

Acrolein — Fire Hazards Flash Point (deg. F) <0 OC -13 CC Flammable Limits in Air (%) 2.8 -31 Fire Extinguishing Agents Foam, dry chemical, carbon dioxide Fire Extinguishing Agents Not To Be Used Water may be ineffective Special Hazards of Combustion Products Poisonous vapor of acrolein is formed from hot liquid Behavior in Fire Vapor is heavier than air and may travel a considerable distance to a source of ignition and flash back. Polymerization may take place, and containers may explode in fire Ignition Temperature (deg. F) 453 Electrical Hazard Data not available Burning Rate 3.8 mm/min. Chemical Reactivity Reactivity with Water No reaction ... 

Acrolein is a highly toxic material with extreme lacrimatory properties. At room temperature acrolein is a liquid with volatility and flammability somewhat similar to acetone bn unlike acetone, its solubility in water is limited. Commercially, acrolein is always stored with hydroquinone and acetic add as inhibitors. Special care in handling is required because of the flammability, reactivity, and toxidty of acrolein.
