Germany TRGS 900 Workplace exposure limits updated

On 30 November 2017, the German Committee on Hazardous Substances (Ausschuss für Gefahrstoffe – AGS) Technical Rules for Hazardous Substances (TRGS) 900 Workplace exposure limits were updated. 16 substances were added to the list, whilst limits for 12 substances were updated. Occupational exposure limits (OELs) are upper limits on the acceptable air concentrations of hazardous substances in the workplace. These limits are typically set by competent national authorities and enforced by legislation to protect occupational safety and health (OSH). OELs are an important tool in risk assessment and in the management of activities involving handling of dangerous substances. Values for a reference period of 8-hour time weighted average (long-term exposure limits, LTELs) and for a short-term period of 15 minute (short-term exposure limits, STELs) are provided in two different units – parts per million (ppm) and milligrams per cubic metre (mg/m3).
