Field Comparison of Two Sampling Methods for Triglycidyl Isocyanurate


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.
