Liquid Dispersion Process Equipment Cleanup Controls

Operation

Post operation clean-up of liquid dispersion process equipment.

If dry nanoparticles were dispersed in the equipment, more conservative controls should be used as identified in the cleaning of dry powder process equipment.

Controls

  • Damp laboratory wipes shall be used to minimize particulate generation
  • Latex or nitrile clean room gloves
    • Contaminated gloves must be disposed of in the same closed receptacle.
  • If an exhausted enclosure is not available, PPE should be used to minimize potential for respiratory, dermal and eye exposure
  • Laboratory wipes shall be disposed of in closed receptacles that are in a ventilated enclosure

Alternatively, Control Banding may be employed when more is known about material reactivity, exposure duration and material state.
