Workplace Exposure Limits (WELs) Consultancy

What are workplace exposure limits?

Workplace exposure limits (WEL) are the legal limits set on the amount of substances that can be present in workplace air.

Hazardous substances must be below the relevant workplace exposure limit. Importantly if the substance is known to cause cancer, genetic defects, allergy or asthma symptoms, or allergic skin reaction exposure, the level must be reduced to as low as reasonably practicable.

On August 21 2018, the Health and Safety Executive (HSE) implemented new and revised Indicative Occupational Exposure Limit Values (IOELVs) for thirty-one chemical substances to help protect workers from the ill-health effects of exposure to hazardous substances in the workplace.

Particles and Health 2021

  • 20 October 2021
  • Running from the 20.10.21 to 21.10.21

IOM is proud to be sponsoring the Particles and Health conference, a two day event designed for regulators and researchers to:

  • Address scientific studies regarding human health effects of PSLTs. The value of human studies over animal studies-when human-exposed populations can be studied adequately- will be emphasized.
  • Review and discuss definition of PSLT’s proposed at Edinburgh workshop and published in 2020 in the Journal Inhalation Toxicology with attention to both similarities and differences among these substances.
  • Address translational toxicology challenges, including the appropriateness of rats as models for human lung pathogenesis (particularly lung cancer) in light of lung overload phenomena and species differences.
  • Serve as a platform to present current scientific information about PSLTs important for regulatory action.
  • Publication of pertinent conference presentations in the peer reviewed scientific literature will allow the presentations to live beyond the conference and subsequently be reviewed part of regulatory deliberations.
  • Establish an interdisciplinary setting for industry, academia and regulatory professionals to interact on an important topic. Such interaction can facilitate enhanced understanding of the science and appropriate classification, labelling and setting exposure limits, among others.
  • Recommend areas for further research regarding the significance of the rat as a model for translation toxicology. 
  • Review the biokinetics of inhaled nanoparticles and the potential for non-pulmonary effects.
