• Description:
  Nanoparticles are very small, about 100,000 times smaller than the width of a human hair. Manufacturers of construction products are using silver nanoparticles to improve the properties of an increasing number of materials, including lumber, flooring products, paints, and coatings. Nano silver is being added to paints and coatings to prevent mold and bacteria from growing on exterior and interior surfaces like wood, masonry, drywall, plaster, and metal. Workers can breathe in nano silver when they spray these types of paints and coatings or disturb them after drying. The National Institute for Occupational Safety and Health (NIOSH) believes nano silver might be harmful to workers because it can harm the lungs and liver in laboratory animals. NIOSH has recommended an exposure limit for silver nanoparticles that is much lower than the Occupational Safety and Health Administration (OSHA) Permissible Exposure Limit for normal airborne silver dust OSHA has no specific standard for any engineered nanomaterial, but other standards, like respiratory protection or hazard communication, may apply. Remember This: 1. Use a hand-held masonry saw attached to a vacuum with a HEPA filter or a masonry saw that uses wet methods to capture dust before it gets into the air. 2. Use a respirator when cutting masonry if the vacuum or wet method alone does not capture enough of the dust. 3. Wear goggles or a face shield to protect your eyes from the dust and hearing protection to prevent hearing loss. [Description provided by NIOSH]
