National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Measurement of Worker's Exposure to Styrene.

PB89129589

Publication Date	1988
Personal Author	Cohen, B. S.; Malek, R.
Page Count	26
Abstract	Studies were conducted to determine the effectiveness of personal samplers in the work place by documenting the magnitude of the variability in breathing zone concentrations of styrene (100425) within the reinforced plastics industry, determining factors which contribute to breathing zone concentrations and investigating the stability of styrene samples taken with charcoal tubes. Measurements were taken at a facility for manufacturing boats where the production process included spraying a catalyzed resin solution along with chopped fiberglass onto a mold. The average background air concentration was 18mg/m3. The personal exposure concentrations were: nose, 327mg/m3; left lapel, 365mg/m3; right lapel, 388mg/m3; and chest, 430mg/m3. Factors affecting the concentration in the breathing zone included air flow patterns, the hood face velocity, and the position of the worker relative to the hood and relative to the spray gun. Styrene, being a volatile and reactive compound, may undergo physical and chemical changes such as vaporization, oxidation and polymerization, any of which would cause underestimation if they occurred following the sample collection. Samples collected on charcoal were stable up to 4 weeks in storage.
