NL - OEL for methyl metacrylate 20.01.2012
In 2005, the Scientific Committee on Occupational Exposure Limits (SCOEL), an advisory committee of the European Committee, published an evaluation on the toxicity of methyl methacrylate. At request of the Minister of Social Affairs and Employment, the Dutch Expert Committee on Occupational Safety (DECOS) of the Health Council, reconsidered the former health-based occupational exposure limit for methyl methacrylate, based on the SCOEL assessment, and additional studies published since 2005, and up to October 2011.
MMA is a clear, colourless, inflammable liquid with a sharp odour. The compound can polymerise readily under the influence of light, heat, oxygen, ionising radiation, and catalysts.
Methyl methacrylate is used in the manufacture of paints, acrylate emulsions, polyvinyl additives, fibres, and unsaturated polyester resins. There are many applications, such as in acrylate plastic (Plexiglass, Perspex), artificial nails, protheses (such as bone cement and dentures), and in coating of contact lenses. MMA is easily absorbed through the skin and the respiratory tract. Inhalation of methyl methacrylate can irritate the nose.
The Health Council of the Netherlands, established in 1902, is an independent scientific advisory body. Its remit is “to advise the government and Parliament on the current level of knowledge with respect to public health issues and health (services) research...”
