Occupational Exposure Limits in the Netherlands are set by the Deputy Minister for Social Affairs and Employment. The Occupational Exposure Limit (OEL) is defined as the airborne concentration of a substance (expressed as a weighted average in time for a working day of 8 hours/day and 40 hours/working week) under which it is believed that nearly all workers may be repeatedly exposed (day after day, over a working lifetime) without adverse health effects (ACGIH, 2006; DFG, 2005). 116 1700−5). Aside from a handful of European countries, some Canadian Provinces and Mexico, most other countries do not have as stringent of a standard as the current U.S. Based on the available data, the occupational exposure limit cannot be determined. When calculating the exposure level, if the exposure period is less than 8 hours then the exposure limit can be increased providing that exposure above the LTEL value does not exceed any short term exposure limit (STEL) and that the LTEL is not exceeded over the 8 hours. Category 3: High Exposure.
