Assessment of health effects and methods for the measurement of exposure levels in workplace atmospheres for methylamine.

This document summarises the work of the Expert Committee on expert appraisal for recommending occupational exposure limits for chemical agents (OEL Committee) and the Working groups on health effects and on metrology. 

On 12 June 2007, AFSSET, which became ANSES in July 2010, was requested by the Directorate General for Labour to conduct the expert appraisal work required for establishing recommendations on measures to be taken in the event of specific exposure profiles such as those with peaks. 

A first report1 published in June 2009 issued recommendations on measures to be taken in the event of an 8h-OELV with no short-term exposure limit (STELV). I

n 2010, ANSES published a second report that recommended studying the 36 substances in France with a short-term exposure limit but no time-weighted average (TWA) to recommend health values taken from the most recent scientific literature (ANSES, 2010). 

In this context, an assessment was undertaken for methylamine, which has a short-term exposure limit in France set at 12 mg.m-3 in a Circular2 of 1982 but no TWA.
