Is MIBK hazardous?

* Exposure to high concentrations can cause you to feel dizzy and lightheaded, and to pass out. * Prolonged contact can cause a skin rash, dryness and redness. * Methyl Isobutyl Ketone may damage the liver and kidneys. * Methyl Isobutyl Ketone is a FLAMMABLE LIQUID and a FIRE HAZARD.


EPA denied this petition based on the conclusion that Volatile Organiz Compounds (VOCs), such as MIBK, contribute to the formation of tropospheric ozone which is known to cause significant adverse effects to human health and the environment.

What does MIBK stand for?

Methyl isobutyl ketone
Methyl isobutyl ketone (MIBK) is the common name for the organic compound 4-methylpentan-2-one, condensed chemical formula (CH3)2CHCH2C(O)CH3. This colourless liquid, a ketone, is used as a solvent for gums, resins, paints, varnishes, lacquers, and nitrocellulose.

Is MIBK a carcinogen?

EPA has classified methyl isobutyl ketone as a Group D, not classifiable as to human carcinogenicity.

Is MIBK flammable?

Under current U.S. OSHA’s Hazardous Communication program MIBK is classified as a flammable liquid, can cause serious eye irritation, and is harmful if inhaled. Keep the material away from heat sources, hot surfaces, open flames, and sparks. Use only in a well- ventilated area.

Is MIBK an organic solvent?

Methyl Isobutyl Ketone (MIBK) is an organic compound that has a low odour and is referred to as an oxygenated solvent.

Why is MIBK a good solvent?

MIBK is a ‘true’ or active solvent due to its compatibility with a variety of organic components and its ability to dissolve them on its own without the need for an alcohol, which can help to simplify system formulations. It also has the ability to combine with lower-cost hydrocarbon solvents in solvent blends.

Is MIBK polar solvent?

Methyl Isobutyl Ketone (MIBK) is a clear liquid with a mild characteristic odor; miscible in oil, soluble in water. MIBK is a polar solvent.

Why do I keep smelling nail polish?

Some people sniff nail polish on purpose to get intoxicated (drunk) by the fumes. Over time these people, as well as those working in poorly ventilated nail salons, can develop a condition known as “painter syndrome.” This is a permanent condition that causes walking problems, speech problems, and memory loss.

What are the NFPA 30 standards?

NFPA Classifications: NFPA 30 uses two terms (flammable and combustible) in their classification of materials. Class I liquids are flammable, while Class II and III liquids are combustible. A flammable liquid is one having a flash point below 100 F (37.8 C) and having a vapor pressure not exceeding 40 lbs.

Is methyl isobutyl ketone a ketone?

?) Methyl isobutyl ketone ( MIBK) is the organic compound with the formula (CH 3) 2 CHCH 2 C (O)CH 3. This colourless liquid, a ketone, is used as a solvent for gums, resins, paints, varnishes, lacquers, and nitrocellulose.

How many workers are exposed to methyl isobutyl ketone in the US?

NIOSH (NOES Survey 1981-1983) has statistically estimated that 612,921 workers (110,397 of these are female) are potentially exposed to methyl isobutyl ketone in the US (1).

What is the best extinguishing media for methyl isobutyl ketone?

Suitable extinguishing media: Use water spray, alcohol-resistant foam, dry chemical or carbon dioxide. Sigma-Aldrich; Safety Data Sheet for Methyl Isobutyl Ketone. Product Number: PHR1556, Version 5.3 (Revision Date 09/23/2016).

What is the effluent concentration of methyl isobutyl ketone?

Methyl isobutyl ketone had influent concentrations of 8100, 8100 and 190 ug/L and effluent concentrations of 27.5, 40.5 and <10 ug/L using an activated sludge with a daily mass loading of COD/bacterial mass ratios of 0.1, 0.36 and 0.48, respectively (5).
