Researchers at the National Institute for Occupational Safety
and Health have published new information to protect
researchers, lab staff, janitors, and others who are potentially
exposed. The benefits of nanotechnology are seemingly limitless,
according to NIOSH. It lists everything from improved disease
diagnoses, treatment technologies, and the creation of more
efficient products to improve methods in water purification or
energy conservation. But research suggests exposure to
nanomaterials may interfere with lung function and other organs
and possibly cause systemic effects. Nanoparticles may be
inhaled, ingested, or absorbed by workers. A new NIOSH guidance
paper suggests employers implement a comprehensive risk
management program, including specific engineering controls and
safe work practices to be followed when working with engineered
nanomaterials in research labs.Among them are: - Hazard
identification -- to understand the characteristics of
nanomaterials that may pose a risk. - Exposure assessment
