EH40/2005 Workplace Exposure Limits (WELs) are a crucial aspect of occupational health and safety, particularly in industries where workers are exposed to various substances that could be hazardous to their health. The EH40/2005 document, updated regularly, contains a list of exposure limits to help employers comply with the Control of Substances Hazardous to Health Regulations 2002 (as amended).

The latest version of EH40/2005, published in 2020, includes significant updates. It reflects the new limits for substances listed in Directive 2017/164/EU, the fourth Indicative Occupational Exposure Limit Values (IOELV) directive, ensuring that the workplace exposure limits are in line with the latest scientific and occupational health research.

Workplace Exposure Limits (WELs) are legal limits set by the Health and Safety Executive (HSE) on the amount of substances that can be present in workplace air. These limits are based on a worker’s time-weighted average over a specified period, typically eight hours. They are designed to protect workers from the harmful effects of substances they might inhale while at work.

It’s important for employers and safety professionals to stay updated with these limits as they are subject to change based on new scientific evidence. Adhering to these limits not only ensures legal compliance but also promotes a safer, healthier work environment.
