Dispersion Workspace Cleanup Exposure Potential

Exposure to nanoparticles in liquid dispersion should have a lower exposure potential for inhalation, but potential for dermal exposure. If the hazard of the nanomaterial is high or unknown, very conservative engineering controls should be employed to limit exposure to the nanomaterials. If the hazard of the nanomaterial is low, reasonable precautions should be taken to limit dermal exposure to the dispersion.

If dry powders were processed in the work space, the cleanup should use more conservative procedures required for dry powder cleanup.
