Occupational Health and Safety Issues

The Air & Waste Management Association (A&WMA) recently announced the formation of an Intercommittee Task Force (ITF) on Nanoscale Science and Engineering. The ITF will span a wide array of subjects, including environmental policy, measurement, health effects, monitoring, management, and safety issues associated with the development and use of nanomaterials, nanotechnologies, and nanoscale products. Its objectives

On September 12, 2013, the National Research Council (NRC) released a report entitled Research Progress on Environmental, Health, and Safety Aspects of Engineered Nanomaterials. The U.S. Environmental Protection Agency (EPA) asked the NRC to perform an independent study to develop and monitor the implementation of an integrated research strategy to address the environmental, health, and

On April 15, 2013, the Institut de recherche Robert-Sauvé en santé et en sécurité du travail (IRSST) and NanoQuébec announced they will jointly fund three new research projects on worker exposure to engineered nanoparticles. The principal researchers for these projects, their affiliations, and the titles of the projects selected are:

  • Nathalie Tufenkji, McGill University, “Measuring the

An April 26, 2013, USA Today article entitled “CDC sets carbon nanotech safety guidelines” reports on the National Institute of Occupational Safety and Health (NIOSH) Current Intelligence Bulletin (CIB) 65, Occupational Exposure to Carbon Nanotubes and NanofibersThe article includes comments from Andrew Maynard, Chair of Environmental Health Sciences at the University

On April 24, 2013, the National Institute for Occupational Safety and Health (NIOSH) released Current Intelligence Bulletin 65: Occupational Exposure to Carbon Nanotubes and Nanofibers, which includes a proposed recommended exposure limit (REL) that is significantly lower than that in the 2010 draft. NIOSH issues Current Intelligence Bulletins (CIB) to disseminate new scientific information about occupational

The United Kingdom’s (UK) Health and Safety Executive (HSE) has posted a guidance document describing how to control occupational exposure to manufactured nanomaterials in the workplace. HSE intends the guidance to assist in compliance with the Control of Substances Hazardous to Health Regulations 2002 (COSHH) (as amended). HSE states that the guidance is specifically about the manufacture

On March 18, 2013, Safe Work Australia (SWA) released two research reports examining nanotechnology work health and safety issues, Investigating the Emissions of Nanomaterials from Composites and Other Solid Articles During Machining Process and Evaluation of Potential Safety (Physicochemical) Hazards Associated with the Use of Engineered Nanomaterials. SWA noted the perceived safety risks of nanomaterials

On March 11, 2013, the European Union’s (EU) FP7 project on Mitigation of Risk and Control of Exposure in Nanotechnology-based Inks and Pigments (nanoMICEX) announced publication of its first newsletter. According to nanoMICEX, project participants have been working to improve the conditions for workers in the inks and pigments industry, and the newsletter describes the

On March 11, 2013, at the annual meeting of the Society of Toxicology, researchers from the National Institute for Occupational Safety and Health (NIOSH) reported preliminary findings from a new laboratory study in which mice were exposed by inhalation to multi-walled carbon nanotubes (MWCNT). According to NIOSH, the study was designed to investigate whether these tiny particles have potential to initiate or promote cancer. One group of laboratory mice was injected with a chemical that is a known cancer initiator, and another group of mice was injected with a saline solution as a control group. The mice then were exposed by inhalation either to air or to a concentration of MWCNT. According to NIOSH, mice receiving both the initiator chemical plus exposure to MWCNT were significantly more likely to develop tumors and have more tumors than mice receiving the initiator chemical alone. Additionally, mice exposed to MWCNT and to MWCNT plus the initiator chemical had larger tumors than the respective control groups. NIOSH concluded that the results indicate that MWCNT can increase the risk of cancer in mice exposed to a known carcinogen. NIOSH notes that the study does not suggest that MWCNTs alone cause cancer in mice.

The Occupational Safety and Health Administration (OSHA) recently published a fact sheet entitled Working Safely with Nanomaterials. OSHA notes that workers who use nanotechnology in research or production processes may be exposed to nanomaterials through inhalation, skin contact, or ingestion. OSHA intends the fact sheet to provide “basic information to workers and employers on the most
