NIOSH Publishes Blog Item on Art and Science of OELs for Nanomaterials

Posted in Federal, Occupational Health and Safety Issues, United States
On February 1, 2017, the National Institute for Occupational Safety and Health (NIOSH) posted a blog item entitled “The Art and Science of OELs for Nanomaterials.”  According to the item, NIOSH searched for proposals for occupational exposure limits (OEL) for new nanomaterials as part of the development of a World Health Organization (WHO) guideline for… Continue Reading

ISO Standard Provides Overview of Frameworks for Developing OELs and OEBs for NOAAs

Posted in International, Occupational Health and Safety Issues
On November 21, 2016, the International Organization for Standardization (ISO) released ISO/TR 18637:2016, “Nanotechnologies — Overview of available frameworks for the development of occupational exposure limits and bands for nano-objects and their aggregates and agglomerates (NOAAs).”  ISO notes that occupational exposure limits (OEL) are generally substance-specific.  In some case, there is insufficient data to develop… Continue Reading

Posted in International, Legal/Regulatory Issues, Occupational Health and Safety Issues
The United Kingdom’s Health and Safety Laboratory (HSL) of the Health and Safety Executive (HSE) prepared a report entitled Summary of work undertaken to assess workplace exposure and control measures during the manufacture and handling of engineered nanomaterials.  The report notes that HSE and HSL attempted to identify and engage with companies that manufactured or… Continue Reading

Federal Advisory Council on Occupational Safety and Health Considers Dispersible Engineered Nanomaterials

Posted in Federal, Legal/Regulatory Issues, Occupational Health and Safety Issues, United States
The Federal Advisory Council on Occupational Safety and Health (FACOSH) met on May 3, 2012, during which it discussed the use of occupational exposure levels (OEL) by the federal government. Because the Occupational Safety and Health Administration’s (OSHA) permissible exposure limits (PEL) have remained unchanged since their adoption on May 29, 1971, and do not account… Continue Reading

Bayer Material Sciences Announces OEL for Baytubes

Posted in Occupational Health and Safety Issues, Research
Last month, Bayer Material Science (BMS) announced that it derived an occupational exposure limit (OEL) of 0.05 milligrams per cubic meter (mg/m3) for Baytubes, BMS multi-wall carbon nanotubes. According to BMS, “[t]he latest results of sub-chronic inhalation studies support the conclusion that Baytubes act like poorly soluble particles.” BMS derived the OEL based on previous single and… Continue Reading
