| Summary: |
BASF AG, a German chemical company, published this guideline for its workers involved with products involving nanoparticle dust. It states that inhalation of nanoparticle dust can be a health hazard, and suggests protective measures. Because the value at which occupational exposure becomes hazardous is not yet known, workers should have their exposure restricted to that of the non-contaminated ambient air. On the other hand, the health risk for dermal exposure to nanoparticle dust is currently estimated as low and “suitable protective measures” should be taken. Nanoparticles should be manufactured in closed systems to the extent possible. If exposure is necessary, additional steps such as extractor systems should be implemented to reduce dust formation. Respiratory filters, gloves, and protective overalls are all effective at reducing exposure. Lastly, workplaces should be monitored for nanoparticle dust exposure in the number of particles and their size distribution. |
