Operation
Clean up dry, engineered nanomaterials using:
- A dedicated, approved HEPA vacuum whose filtration effectiveness has been verified (Note: Consider possible pyrophoric hazards associated with vacuuming up nanoparticles)
- Wet wiping (Note: Consider possible reactivity of nanoparticles with the wipe solvent)
- Other facility-approved methods that do not involve dry sweeping or the use of compressed air
- Dispose of used cleaning materials and wastes in accordance with the home Laboratory’s hazardous-waste procedures
Controls
- PPE should be used to minimize potential for respiratory, dermal and eye exposure
- Latex or nitrile clean room gloves
- Verified respiratory controls depending on the materials
Alternatively, Control Banding may be employed when more is known about material reactivity, exposure duration and material state.
