Recommendation of the Scientific Committee on Occupational Exposure Limits for Hydrogen peroxide

Hydrogen sulfide: UK occupational exposure limits.

Hydrogen sulfide (H2S) is a toxic gas with an offensive odour reminiscent of rotten eggs. There is the potential for widespread occupational exposure to H2S, including in the oil and water treatment industries. There is a particular concern for exposure in confined spaces such as manholes and sewer pipes; the high concentrations that can build up in such conditions (> 1000 parts per million (pp...

The Scientific Basis of Uncertainty Factors Used in Setting Occupational Exposure Limits

The uncertainty factor concept is integrated into health risk assessments for all aspects of public health practice, including by most organizations that derive occupational exposure limits. The use of uncertainty factors is predicated on the assumption that a sufficient reduction in exposure from those at the boundary for the onset of adverse effects will yield a safe exposure level for at lea...

Occupational exposure limits for chemicals.

Occupational exposure limits (OELs) are tools to help employers protect the health of those who may be exposed to chemicals in their workplace. Under the United Kingdom Control of Substances Hazardous to Health (COSHH) Regulations they define adequate control by inhalation. OELs are set by the Health and Safety Commission (HSC) on advice from its Advisory Committee on Toxic Substances (ACTS) an...
