| Summary: |
This guidance document from the Massachusetts Office of Technical Assistance makes recommendations for the safe development of nanotechnology. It is suggested that facilities handling engineered nanoparticles develop a risk reduction program that prevents exposures, even if the harm from exposure is not yet fully known. The risk reduction plan should be divided into two levels: direct and eventual potential impact. Design options that render nanoparticle-containing products safer to end users and the environment will not only reduce risk, but also legal liability. Worker safety programs should evaluate air movement near potential nanoparticle release points and ensure that free nanoparticles do not become inhaled by workers. It is also suggested that nanoparticles with lower toxicity or other non-nano materials be substituted for high toxicity nanoparticles, if possible. For example, adjusting the fiber length of carbon nanotubes may reduce toxicity. Containment and ventilation controls must be used to ensure that nanoparticles are not released into the workplace, and when this is not possible, personal protective equipment (PPE) should be used. Recommendations for preventing facility releases, transparency of information, recognizing the value of prevention, and realizing the value of nanotechnology are also contained in this document. |
