Walk-through survey report: styrene and noise exposures during fiber reinforced plastic boat manufacturing at Grady-White Boats, Inc., Greenville, North Carolina, report no. CT-306-12a.
NIOSH 2005 Sep; :1-11
The National Institute for Occupational Safety and Health (NIOSH) is part of the Centers for Disease Control and Prevention (CDC) in the U.S. Department of Health and Human Services (DHHS). NIOSH was established in 1970 by the Occupational Safety and Health (OSH) Act, at the same time that the Occupational Safety and Health Administration (OSHA) was created in the U.S. Department of Labor (DOL). The OSH Act mandated NIOSH to conduct research and education programs separate from the standard-setting and enforcement functions conducted by OSHA. An important area of NIOSH research involves measures for controlling occupational exposures to potential chemical and physical hazards. On June 30, 2005, researchers from the Engineering and Physical Hazards Branch (EPHB) of the Division of Applied Research and Technology (DART) conducted a walkthrough survey at Grady-White Boats, Inc. in Greenville, North Carolina. 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 FRP boat manufacturing process mainly used at Grady-White is known as the open molding process. Cold-press pneumatic molding (a form of closed molding) is used to fabricate small hatch covers. The facility has 350,000 square feet of floor area and employs 360 to 470 people depending on demand. This is the only facility that manufactures Grady-White brand boats. The boat size range is from 18 to 36 feet in length. The facility operates one shift per day beginning at 7:00 a.m. There are approximately 1,700-2,000 boats made per year including many different models. Most models sell from 50 to 200 boats per year.
