  Toolbox talk: airborne exposures when working with nano-enabled concrete
• Corporate Authors:

• Description:
  Materials that contain engineered nanomaterials are called nano-enabled. Carbon nanotubes, graphene, nanocellulose, silica nanoparticles, and titanium dioxide are added to cement and concrete to increase their strength, reduce cracking, and improve resistance to water damage. Workers can breathe in the nanomaterials when they cut, grind, drill, or disturb nano-enabled concrete and the dust gets in the air. The National Institute for Occupational Safety and Health (NIOSH) has recommended exposure limits for multi-walled carbon nanotubes and nano-sized titanium dioxide because they cause lung damage and cancer in laboratory animals. The Occupational Safety and Health Administration (OSHA) has a standard that has exposure limits for dust containing silica, however, it has no specific standards addressing nanomaterials.
