Cleaning of nanoparticles
Nanoparticles can be invisible and adhere to all available surfaces - it may be on ceilings, walls, lab coats, floors, etc. The person handling nanoparticles is responsible for the subsequent cleaning, as it is too risky for untrained cleaning staff to carry out the cleaning. It must be stated in the Nano APV, which level of cleaning is sufficient and a procedure for the cleaning.
When cleaning e. g. inside a fume hood, a full personal protection it is a requirement, and if possible, the fume hood is set at maximum air velocity.
When handling nanoparticles outside the fume hood / safety cabinet, or spillage occurs on the floor, it is a requirement that everyone in the room has full personal protection. Therefore, have a waste kit ready. The cleaning procedure must subsequently be checked by a control measurement and released for normal use.
It is recommended to use wet cloth and use very slow movements during cleaning.
The Nano APV must describe how cleaning cloths are securely sealed and sent to waste. If reused, It is necessary to consider how the personal protective equipment is cleaned, or how it is safely sent to waste. In addition, the room must be released by a control measurement to check that the cleaning procedure meets the specifications.
The Nano APV must describe how nanoparticles remain inside the closed systems. Glassware, etc., must be washed before removing from the fume hood, and submitted to a following dish wash. Gloves and protective sleeves also remain inside the fume hood. Closed waste bin and sealed waste bags must be wiped on the outside before removing from the fume hood, and submitted to a following storage in ventilated chemical cabinets until sent to the waste station. The outside of chemicals, buckets, equipments etc. that leave the closed system are wiped out before removed.
