Dry Powder Material Unpacking Controls

Operations Unpacking dry powders when there is the potential for aerosolization and release of nanomaterials into the workplace atmosphere.

Controls

  • Ventilated Laboratory Hood or local exhaust enclosure with HEPA* exhaust filtration
  • If an exhausted enclosure is not available, PPE should be used to minimize potential for respiratory, dermal and eye exposure
  • Latex or nitrile clean room gloves
  • Wet cleaning of laboratory hood surfaces or local exhaust enclosure following conclusion of handling operations
  • The filtered air must not be recirculated into the workplace.

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