Nanomaterials in Construction: Tracking Product Diffusion and Measuring Exposures
Len Burrelli, Daniel Marsick, Alan Segrave, Gavin West
This effort will identify nano-enabled products that are being installed or used by U.S. construction workers and rate the exposure potential of the products using focus groups of affected trades persons. The Center has created a dedicated website as part of its electronic Library of Construction Occupational Safety and Health that contains information on over 400 construction products that are probably nano-enabled. Those that are identified as posing the greatest risks will be selected for breathing zone measurements of various trade workers performing tasks with standard tools. This proposal also includes an evaluation of the effectiveness of control technologies to reduce exposures and an identification of the most promising existing local exhaust systems and wet methods technologies in the Center’s Construction Solutions database and elsewhere. Industrial hygiene measurements with personal sampling pumps, area samplers and real-time particle counters will be made inside a controlled test chamber to reduce extraneous sources of particles. The Center will disseminate the findings to broad audiences through the varied and extensive communication tools that the Center maintains, including the Electronic Library for Construction Safety and Health (eLCOSH), which receives 40,000 visits per month, Hazard Alerts and CPWR UPDATES. The communications tools that will be generated to diffuse the findings includes toolbox talks, Construction Solutions for controlling exposures, CPWR Hazard Alerts and UPDATES, two technical papers, two roundtables and five presentations at professional conferences, and two webinars. The Center has already shared the product inventory with NIOSH’s Nanotechnology Research Center (NTRC) and will continue to collaborate closely with the NTRC.
