Operations

Handling, mixing or measuring 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
  • The filtered air must not be recirculated into the workplace.
• 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

Material Specific Controls

• Carbon Nanotubes
