CNT Cleanup

When cleaning the workspace: 

Lab coat, HEPA filtration respirator mask, chemical safety goggles or face shield, chemical gloves. Keep laboratory doors closed and locked during cleaning. Use HEPA vacuum cleaner to pick any stray material and/or use wet wipe methods for any CNT material settled on surfaces.  Use of conventional vacuum cleaners is prohibited as this may resuspend CNT particles (This hazard was verified by OSHA personnel).

For trace amounts of bound material to container surfaces, use wet wipe methods.

At present, the numerous studies indicate that CNT has the potential as a moderately hazardous material for respiration. The transfer process is short term, for free/unbound material, so we believe this corresponds to control band #2. Skin contact does not appear to be a route for uptake into the body, and standard laboratory hygiene practices should be adequate here.
