Walk-through survey report: styrene and noise exposures during fiber reinforced plastic boat manufacturing at Sea Ray Boats, Inc., Vonore, Tennessee, report no. CT-306-14a.
NIOSH 2005 Dec; :1-14
On October 27-28, 2005, researchers from the Engineering and Physical Hazards Branch (EPHB) of the Division of Applied Research and Technology (DART) conducted a walkthrough survey at Sea Ray Boats Inc., in Vonore, Tennessee. The primary purpose of this walk-through was to learn more about the fiberglass-reinforced plastic (FRP) boat manufacturing industry and to assess the suitability of this facility for an in-depth survey. The main goals for the walk-through survey included performing a preliminary assessment of the occupational exposures to styrene vapor in air and observing the effectiveness of engineering exposure-control measures during the FRP boat manufacturing operations. A secondary objective was to perform a preliminary assessment of the noise exposures occurring during these operations. The Tellico Plant has gone to great lengths to automate many steps required to build FRP boats. The robotic forming and finishing processes allows for controlled use of styrene containing products and lower styrene exposures for employees. The company representatives believe that cross-contamination from open molding to closed molding can exist due to the proximity of the two manufacturing lines. Adjacent to the ZIP closed-molding production line is an open-molding lamination line. NIOSH researchers collected three styrene detector-tube samples (robotic gelcoating, injection molding, and pulling of mold) on a different day in order to avoid cross contamination. An in-depth survey is recommended for this plant.
