Example of Hazardous Chemical Label

Health and Safety Executive Guidance Note EH40
OELs are legal limits on the airborne concentrations of substances that workers can be exposed
to. In the UK, these OELs are called Workplace Exposure Limits (WELs) and they are published
by the Health and Safety Executive (HSE) in Guidance Note EH40. This document can, therefore,
be a useful source of reference when undertaking a hazardous substance risk assessment.
WELs will be explained fully in the next section of this element.
