ABSTRACT:
Side-by-side field sampling comparisons for
Triglycidylisocyanurate (TGIC) were conducted
using 1) a laboratory method to determine specific levels of airborne TGIC, and
2) the NIOSH 0500 method for Particulates Not Otherwise Regulated for total
aerosol mass. Resulting concentrations from the NIOSH 0500 method in
conjunction with the powder coating manufacturer safety data sheet are then
used to estimate TGIC levels in air. This second method is designed as a
simpler and less expensive sampling and analytical method. Results show that
the NIOSH 0500 method resulted in airborne concentrations up to ten times
greater than the laboratory method resulting in specific for TGIC. Coefficients of variation show that the laboratory method had the least variability. We
conclude that the NIOSH 0500 method and subsequent calculation should not be
used to quantify TGIC levels in powder coatings. However, this method may be
used to monitor effectiveness of exposure
control.
