NIOSH recommendations are expected to help establish risk management practices for controlling exposure to these particles. The agency recommends that employers should:
- Reduce worker exposures to airborne concentrations to no more than 1 microgram per cubic meter of air as a recommended exposure limit.
- Apply strategic approaches for controlling occupational exposures, giving priority to engineering controls that enclose processes where CNTs or CNFs could be released into the air.
- Train workers on the safe handling of bulk quantities of the particles, and proper use of engineering controls, administrative controls and safe work practices.
- Establish health surveillance and medical screening programs to identify early signs of respiratory disease.
