Spill Cleanup of Dry Powder Procedures and Controls

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."¹

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.

Material Specific Controls

• Carbon Nanotubes
