EH40 – HSE Guidance on Workplace Exposure Limits: A Quick Overview
A government publication listing legally enforceable limits for exposure to hazardous substances (COSHH) in the workplace. Often just called “EH40”, it covers eight-hour (TWA) and short-term (STEL) exposure limits, updated periodically, most recently the fourth edition published January 17, 2020.
Key Updates and Compliance
The latest update to EH40, effective January 17, 2020, introduced stricter limits for several substances, including hardwood dust and respirable crystalline silica. These are in place to protect employee health and avoiding legal penalties.
Implementing EH40 in Your Workplace
Employers should identify hazardous substances, monitor exposure levels, and implement control measures. Training employees on safe practices is vital, along with regular reviews of these safety measures.
What Happens If You Don’t Comply with EH40?
In the UK, EH40 is a document published by the Health and Safety Executive (HSE), listing the Workplace Exposure Limits (WELs) for hazardous substances under the Control of Substances Hazardous to Health (COSHH) Regulations. These limits are legally enforceable and designed to protect workers from harmful exposure to substances such as chemicals, gases, vapours, and dust.
Non-compliance with EH40 can result in serious legal consequences. Businesses that breach COSHH regulations may be subject to prosecution by the HSE. This can lead to unlimited fines and, in more severe cases, criminal charges. Company directors and managers may also be held personally liable, especially if negligence can be proven. The HSE has the power to issue enforcement actions such as Improvement Notices, requiring you to take corrective action within a specified timeframe, or Prohibition Notices, which can halt operations immediately if there is a risk to life or health.
