* “Transfer engineered nanomaterials samples between workstations (such as exhaust hoods, glove boxes, furnaces) in closed, labeled containers, e.g., marked ‘Zip-Lock’ bags.

• Take reasonable precautions to minimize the likelihood of skin contact with engineered nanoparticles or nanoparticle-containing materials likely to release nanoparticles (nanostructures).
• If engineered nanoparticle powders must be handled without the use of exhaust ventilation (i.e., laboratory exhaust hood, local exhaust) or enclosures (i.e., glove-box), evaluate hazards and implement alternative work practice controls to control potential contamination and exposure hazards.
• Handle nanomaterial-bearing waste (see definition above) according to the home Laboratory’s hazardous chemical waste guidelines.
• Vacuum dry engineered nanoparticulates only with an approved HEPA vacuum cleaner that has been performance tested and certified according to the Center’s or Lab’s policies and procedures.”¹
