Ketones

Highly Flammable

METHYL ISOPROPENYL KETONE tends to polymerize; this reaction is mostly suppressed by the inhibitor. Can polymerize if heated or contaminated. If confined in a container when polymerization is initiated, the container may violently rupture (USCG, 1999).

Excerpt from ERG Guide 127P [Flammable Liquids (Water-Miscible)]: As an immediate precautionary measure, isolate spill or leak area for at least 50 meters (150 feet) in all directions. LARGE SPILL: Consider initial downwind evacuation for at least 300 meters (1000 feet). FIRE: If tank, rail car or tank truck is involved in a fire, ISOLATE for 800 meters (1/2 mile) in all directions; also, consider initial evacuation for 800 meters (1/2 mile) in all directions. (ERG, 2016)

Excerpt from ERG Guide 127P [Flammable Liquids (Water-Miscible)]: ELIMINATE all ignition sources (no smoking, flares, sparks or flames in immediate area). All equipment used when handling the product must be grounded. Do not touch or walk through spilled material. Stop leak if you can do it without risk. Prevent entry into waterways, sewers, basements or confined areas. A vapor-suppressing foam may be used to reduce vapors. Absorb or cover with dry earth, sand or other non-combustible material and transfer to containers. Use clean, non-sparking tools to collect absorbed material. LARGE SPILL: Dike far ahead of liquid spill for later disposal. Water spray may reduce vapor, but may not prevent ignition in closed spaces. (ERG, 2016)

/GUIDE 127P: FLAMMABLE LIQUIDS (POLAR/WATER-MISCIBLE)/ Fire or Explosion: HIGHLY FLAMMABLE: Will be easily ignited by heat, sparks or flames. Vapors may form explosive mixtures with air. Vapors may travel to source of ignition and flash back. Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapor explosion hazard indoors, outdoors or in sewers. Those substances designated with a "P" may polymerize explosively when heated or involved in a fire. Runoff to sewer may create fire or explosion hazard. Containers may explode when heated.

Short-term exposures...ranging from 0.291 to 14.5 ppm have been reported. There was a questionable odor but no irritation at 0.291 ppm. At 0.77 ppm, there was an immediate definite odor & the vapors were evident to the eyes after a few min. At 1.45 & 2.91 ppm, eye irritation was apparent. At 14.5 ppm, there was an immediate strong odor with eye irritation...after 2 min. Ocular irritation rapidly increased in severity with time. ... Industrial exposures are likely to be by inhalation, skin & eye contact. Its strong irritating & lacrimatory properties may not prevent toxicity because these effects are often not immediately sensed.

Inhalation causes irritation of nose and throat. Liquid may cause severe damage to eyes, resulting possibly in some permanent impairment of vision; vapor produces tears. If not removed promptly from skin, liquid may cause delayed pain and blistering. Ingestion causes irritation of mouth and stomach. (USCG, 1999)

INHALATION: remove victim from exposure; give artificial respiration if needed; call physician. EYES: immediately irrigate with copious amounts of water for 15 min.; call physician. SKIN: wash off skin with large volumes of water for 15 min.; call physician if burn has occurred. INGESTION: induce vomiting; call physician. (USCG, 1999)
