A lacrimator (causes tearing); an insidious poison which causes delayed skin reactions. Very readily absorbed through skin. Highly toxic. (EPA, 1998)
Severe acute inhalations should be treated like cyanide poisoning. The first priority is to establish adequate ventilation (100% oxygen) and circulation, since cyanide antidotes are theoretically useful but clinically unproven in acrylonitrile poisoning. Acrylonitrile
Usual precautions for flammable liquid should be applied. (EPA, 1998)
Methacrylonitrile evolves flammable concentrations of vapor at temperatures down to 55.04F. Thus, at room temperatures, flammable concentrations are liable to be present. Toxic fumes of nitrogen oxides are released when the material burns. Also, the chemical will explode due to its tendency to polymerize violently. Avoid heat. Hazardous polymerization may occur. (EPA, 1998)
Use alcohol-resistant foam. Use dry powder. Use carbon dioxide. In case of fire: keep drums, etc., cool by spraying with water.
Remove all ignition sources. Evacuate danger area! Personal protection: chemical protection suit including self-contained breathing apparatus. Collect leaking liquid in sealable containers. Absorb remaining liquid in sand or inert absorbent. Then store and dispose of according to local regulations.

Collect and arrange disposal. Keep the chemical in suitable and closed containers for disposal. Remove all sources of ignition. Use spark-proof tools and explosion-proof equipment. Adhered or collected material should be promptly disposed of, in accordance with appropriate laws and regulations.
NO open flames, NO sparks and NO smoking. Closed system, ventilation, explosion-proof electrical equipment and lighting. Handling in a well ventilated place. Wear suitable protective clothing. Avoid contact with skin and eyes. Avoid formation of dust and aerosols. Use non-sparking tools. Prevent fire caused by electrostatic discharge steam.
Store only if stabilized. Fireproof. Cool. Keep in the dark. Separated from food and feedstuffs.

The substance may violently polymerize under the influence of acids, bases and light. This generates fire or explosion hazard. The substance may polymerize due to heating. This generates fire or explosion hazard. On combustion, forms toxic and corrosive fumes including cyanides and nitrogen oxides.

METHACRYLONITRILE EVOLVES FLAMMABLE CONCENTRATIONS OF VAPOR AT TEMPERATURES DOWN TO 12.8 DEG C. THUS, AT ROOM TEMPERATURES, FLAMMABLE ... CONCENTRATIONS ARE LIABLE TO BE PRESENT IN ABSENCE OF PRECAUTIONS. THE NORMAL DANGERS ASSOCIATED WITH FIRE ... ARE INTENSIFIED BY THE LETHAL NATURE OF THE FUMES & VAPORS EVOLVED.The vapour is heavier than air and may travel along the ground; distant ignition possible. Vapours are uninhibited and may polymerize, causing blockage of vents.METHACRYLONITRILE is a colorless, flammable, toxic liquid. Explosive in the form of vapor when exposed to heat, flame or sparks. When heated to decomposition it emits toxic fumes of nitrile and oxides of nitrogen [Lewis, 3rd ed., 1993, p. 829].

A harmful contamination of the air can be reached very quickly on evaporation of this substance at 20°C.
Microorganisms hydrolyze nitriles predominately to ammonia and carboxylic acids(1). A bacterium isolated from soil (Pseudomonas putida) was able to utilize methylacrylonitrile as a sole source of carbon and nitrogen(2). In another study, a mixed microbial culture, isolated from an environment contaminated with organic cyanides and PCBs, utilized methylacrylonitrile as the sole source of carbon and nitrogen(1). The mixed microbial culture was grown for 48 hrs at pH 7 with 1 g/l of methylacrylonitrile; the final pH and ammonia concn were determined to be 8.17 and 40.9 umol/ml, respectively(1).
An estimated BCF of 3 was calculated for methylacrylonitrile(SRC), using a log Kow of 0.68(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC).
The Koc of methylacrylonitrile is estimated as 56(SRC), using a measured log Kow of 0.68(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that methylacrylonitrile is expected to have high mobility in soil(SRC).

The material can be disposed of by removal to a licensed chemical destruction plant or by controlled incineration with flue gas scrubbing. Do not contaminate water, foodstuffs, feed or seed by storage or disposal. Do not discharge to sewer systems.
Containers can be triply rinsed (or equivalent) and offered for recycling or reconditioning. Alternatively, the packaging can be punctured to make it unusable for other purposes and then be disposed of in a sanitary landfill. Controlled incineration with flue gas scrubbing is possible for combustible packaging materials.
