What is Exposure?
Exposure to a substance is uptake into the body. The exposure routes are:
- By breathing fume, dust, gas or mist;
- By skin contact;
- By injection into the skin;
- By swallowing.
The new WELs are published in the Health and Safety Executive publication, which can be accessed via the link below:
The new WELs came into force, in Northern Ireland, on 14 Sept
In the UK IOELVs are transposed as workplace exposure limits (WELs) and short term exposure limits (STELs). A WEL is defined as the concentration of a hazardous substance in the air that people breathe, averaged over a specified reference period referred to as a time-weighted average. Two periods are used: long-term exposure limit is 8 hours and STEL is 15 minutes.
