Exposure Testing

Methyl Methacrylate (MMA) is a volatile organic compound (VOC) that is used as a solvent to aid the curing of a number of industrial processes (laying of resin floors, manufacture of plastics etc)


Due to its low boiling point, MMA readily forms a vapour that has a characteristically pungent smell, so much so that even levels as low as 0.05 ppm can be detected by the human nose.

MMA is irritating to the skin, the eyes and mucous membranes in humans. An allergic response resulting from dermal exposure may develop. Respiratory effects such as coughing and/or shortness of breath have been reported in some humans following acute (short-term) and chronic (long-term) inhalation exposures.

As an employer, you are responsible for taking effective measures to control exposure and protect health.

ActionsActions and advice

Methyl Methacrylate has a legal limit called a ‘workplace exposure limit’ the WEL is set at 50ppm (averaged over an 8-hour working period).

Once an assessment has been carried out to measure the exposure levels any actions should then be taken to either reduce or control exposure as part of an ongoing monitoring regime.

HelpHow can we help?

Our consultants are here to help you with advice and guidance. We offer a free consultation service to identify an appropriate exposure sampling and monitoring regime that will ensure you meet regulatory compliance.

We will then provide you with a no obligation proposal to attend your premises to carryout the site exposure assessment based on the monitoring regime most appropriate for your organisation.

Understanding and Managing Exposure to Volatile Organic Compounds in the Workplace


Within the domain of occupational hygiene, employers face a critical challenge in controlling exposure to hazardous substances. Volatile Organic Compounds (VOCs) constitute a class of chemicals that present a particular risk due to their ability to become airborne as vapours at room temperature. As an employer, it is imperative to comprehend the nature of VOCs, the industries or processes where exposure can occur, the associated health effects, and, most importantly, how to prevent or mitigate exposure effectively.
