Most important symptoms/effects, acute and delayed
This material is readily absorbed through the skin, causing general poisoning, similar to other ketones; inhalation has central nervous system depressant effects. It is irritating to mucous membranes and respiratory tract and to the skin; it is a lachrymator and can cause eye injury. (EPA, 1998)
Indication of immediate medical attention and special treatment needed, if necessary
Basic treatment: Establish a patent airway (oropharyngeal or nasopharyngeal airway, if needed). Suction if necessary. Watch for signs of respiratory insufficiency and assist ventilations if necessary. Administer oxygen by nonrebreather mask at 10 to 15 L/min. Monitor for pulmonary edema and treat if necessary . For contamination, flush eyes immediately with water. Irrigate each eye continuously with 0.9% saline (NS) during transport . Do not use emetics. For ingestion, rinse mouth and administer 5 ml/kg up to 200 ml of water for dilution if the patient can swallow, has a strong gag reflex, and does not drool. Administer activated charcoal . Ketones and related compounds
SECTION 5: Firefighting measures
Suitable extinguishing media
Use dry chemical, "alcohol resistant" foam, carbon dioxide, or water spray. Water may be ineffective. Use water spray to keep fire-exposed containers cool. fight fire from protected location or maximum possible distance. Approach fire from upwind to avoid hazardous vapors and toxic decomp products.
Specific hazards arising from the chemical
Vapors form flammable mixtures with air, and may travel a considerable distance to a source of ignition and flash back. Polymerization may take place in containers, possibly with violent rupture of containers. Upon exposure to heat or flame, it emits toxic and irritating fumes. Container may explode in heat of fire. Vapor explosion and poison hazard indoors, outdoors, or in sewers. Polymerizes on standing. Hazardous polymerization may occur. Avoid heat or sunlight. (EPA, 1998)
Special protective actions for fire-fighters
Use water spray, powder, alcohol-resistant foam, carbon dioxide. In case of fire: keep drums, etc., cool by spraying with water.
SECTION 6: Accidental release measures

SECTION 10: Stability and reactivity
Reactivity
The substance polymerizes under the influence of peroxides, heat, light and oxidants. Reacts with strong bases, strong reducing agents and strong oxidants.
Chemical stability
Polymerizes on standing
Possibility of hazardous reactions
Dangerous fire hazard when exposed to hest, flame, or oxidizers.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.METHYL VINYL KETONE is incompatible with strong oxidizers and strong bases. It polymerizes spontaneously upon exposure to heat or sunlight. This polymerization may cause violent ruptures in containers. (NTP, 1992).
Conditions to avoid
no data available
Incompatible materials

Persistence and degradability
AEROBIC: A theoretical BOD of 10% was determined for methyl vinyl ketone over a 5-day incubation period using the French AFNOR test(1). Using a standard BOD technique with acclimated sewage inoculum, a theoretical BOD of 0% was measured for methyl vinyl ketone over a 5-day incubation period(2).
Bioaccumulative potential
An estimated BCF of 3.2 was calculated in fish for methyl vinyl ketone(SRC), using an estimated log Kow of 0.41(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).
Mobility in soil
Using a structure estimation method based on molecular connectivity indices(1), the Koc of methyl vinyl ketone can be estimated to be 3.8(SRC). According to a classification scheme(2), this estimated Koc value suggests that methyl vinyl ketone is expected to have very high mobility in soil.
Other adverse effects
no data available
SECTION 13: Disposal considerations
Disposal methods
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.

Other Information
The occupational exposure limit value should not be exceeded during any part of the working exposure.The symptoms of lung oedema often do not become manifest until a few hours have passed and they are aggravated by physical effort.Rest and medical observation is therefore essential.An added stabilizer or inhibitor can influence the toxicological properties of this substance, consult an expert.Do NOT take working clothes home.
