| Resumen |
The 3 ethylene oxide excursion limit (EtO EL) dosimeters tested were: 3 M 3550/3551, Crystal Diagnostics Air Scan, and Assay Technology EO CHEM CHIP. A specially designed field exposure chamber exposed 12 dosimeters of each type concurrently at each sampling location while collecting 6 Tedlar bag samples from locations surrounding the dosimeter array. The bag samples were analysed on-site by gas chromatography with flame ionisation detection (GC-FID). Using the Tedlar bag/GC-FID sample data to calculate the "actual concentration" during exposure of the dosimeters, the precision, bias, and accuracy were calculated for each method at exposures bracketing the Occupational Safety and Health Administration (OSHA) EL. The Assay Technology method did not meet the OSHA accuracy requirement at any concentration level studied. The Crystal Diagnostics method did not meet the requirement at EtO concentrations above 2.12ppm. The 3 M method was analysed by the manufacturer and by an outside laboratory. The latter samples did not meet the requirement at concentrations below 9.41ppm. |
