Acrylic acid Chemical explosives

Combustible liquid flash point (closed cup) 54°C (130°F), (open cup) 68 C (155°F) vapor pressure 31 torr at 25°C (77°F) vapor density 2.5 (air = 1) autoignition tempera-tnre 360°C (680°F). Vapors of acrylic acid form explosive mixtures with air within the range 2.9-8.0% by volume in air. Fire-extingnishing agent water spray, alcohol foam, dry chemical, or CO2 nse a water spray to flnsh and dilute the spill and to disperse the vapors. 

DOT CLASSIFICATION 8 Label Corrosive DOT Class 8 Label Corrosive, Poison SAFETY PROFILE Confirmed human carcinogen. A poison. Moderately toxic by inhalation. A corrosive irritant to skin, eyes, and mucous membranes. A very dangerous fire hazard by chemical reaction with reducing agents and carbohydrates. A severe explosion hazard by chemical reaction with acetic acid, acetic anhydride, acetonitrile, acrolein, acrylic acid, acrylonitrile, aUyl...

ACRYLIC ACID, 2-ETHYLHEXYL-ESTER (103-11-7) CnHjoOj Combustible liquid. Forms explosive mixture with air [explosion limits in air (vol %) 0.8 to 6.4 flashpoint 180°F/82°C oc autoignition temp 496°F/258°C Fire Rating 2]. Unless inhibited, contact with heat, sunlight, contaminants, or peroxides may cause hazardous polymerization. Reacts violently ivith strong oxidizers, with risk of fire and explosions. Incompatible with strong acids, alkalis, aliphatic amines, alkanolamines, nitrates. The uninhibited monomer vapor may block vents and confined spaces by, forming a solid polymer material. On small fires, use AFFF, foam, dry chemical, or COj extinguishers. 

CsHjoOj Combustible liquid. Forms explosive mixture with air [explosion limits in air (vol %) 1.6 to uel unknown flash point 149°F/65°C Fire Rating 1]. Unless inhibited (200 ppm hydroquinone recommended), polymerization may occur avoid exposure to high temperatures, ultraviolet light, free-radical initiators. Reacts with water with release of heat may not be violent if not contained. Strong oxidizers may cause fne and explosions. Reacts violently with sodium peroxide, uranium fluoride. Incompatible with strong acids, nitrates. Incompatible with sulfuric acid, nitric acid, caustics, aliphatic amines, isocyanates, boranes. Thermal decomposition releases toxic acrid fumes of acrolein and acrylic acid. On small fires, use dry chemical powder (such as Purple-K-Powder), water spray, alcohol-resistant foam, or CO2 extinguishers. 

EXPLOSION and FIRE CONCERNS combustible NFPA rating Health 3, Flammability 2, Reactivity 0 flammable liquid when exposed to heat, flame or oxidizers reacts violently with acetic acid, acetic anhydride, acrylic acid, acrylonitrile, allyl chloride, carbon disulfide, chlorosulfonic acid, hydrochloric acid, nitric acid, sulfuric acid, ethylene chlorohydrin, oleum, acrolein, or vinyl acetate heating to decomposition emits carbon monoxide, carbon dioxide, hydrocarbons, toxic oxides of nitrogen, and toxic amine vapors use water spray, dry chemical, alcohol foam, or carbon dioxide for firefighting purposes.
