After evaluating the available scientific evidence, NIOSH has determined that it is insufficient to support developing a size-specific recommended exposure limit (REL) for silver nanomaterials. In the absence of information to support a size-specific REL, worker exposures to silver dust, fume, and soluble compounds should be maintained below the NIOSH REL of 10 µg/m3 as an 8-hour time-weighted average.
A report published by the Danish Environmental Protection Agency (EPA) states that inhalation of nanomaterials is the exposure route that provides the most significant health effects to consumers and others.
The American Journal of Industrial Medicine recently reported online a “game changing” Harvard-based report by Dr. Shane Journeay and Dr. Rose Goldman in the field of nanotechnology - toxicology. The study is the first reported or published case in North America of a worker handling nanoparticles in a U.S. manufacturing facility and developing serious health effects.
Prominent at this year’s AIHce were seminars and workshops reflecting the American Industrial Hygiene Association’s (AIHA biennial membership survey listing top public policy issues of concern to AIHA members and the occupational and environmental health and safety (OEHS) profession over the next two years.
Overcoming resistance to near-miss reporting: Easily ignored incidents can be key to improving safety performance. Even though a near-miss incident on a job site may cause no injuries or property or equipment damage, it can give a company a heads’ up about a need for early intervention, thereby enabling it to improve its safety performance.
“Working Safely with Nanomaterials” is a new four-page PDF fact sheet published by OSHA. According to the fact sheet: “Workers who use nanotechnology in research or production processes may be exposed to nanomaterials through inhalation, skin contact, or ingestion.
China should carry out more-extensive safety studies and improve regulatory oversight of synthetic nanomaterials, leading Chinese researchers said at the 6th International Conference on Nanotoxicology in Beijing this month.
