Nanotechnology is transforming many industries, including construction. Nanomaterials are incredibly small — between 1 to 100 nanometers or about 1 million times smaller than the length of an ant. At this size, materials can take on new properties.
Adding nanomaterials or making changes at this tiny size can transform familiar construction materials into concrete that conducts electricity, glass that cleans itself and coatings that cut smog. The industry is only beginning to understand the possible hazards for workers who handle these materials.
The Center for Construction Research and Training has created the website http://nano.elcosh.org/. Visitors to the site — affiliated with the electronic Library of Construction Occupational Safety and Health (elcosh.org) — can learn more about nanomaterials used in the trade and access additional information, including training and guidance documents.
CPWR is moving forward with additional research on nanomaterial exposure risks. In the meantime, the organization has created a pocket-sized Hazard Alert brochure with the best known information on the hazard and how to reduce potential risks. For copies, contact news@cpwr.com. Include postal address and quantity of brochures needed.
