“ Glycidol is irritating to the upper respiratory tract, skin, and mucous membranes and will attack some forms of plastics, rubber and coatings [3] . It is absorbed through skin [4] .
SAMPLING: 1. 2. 3. 4.
Calibrate each personal sampling pump with a representative sampler in line. Break the ends of the sampler immediately before sampling. Attach sampler to personal sampling pump with flexible tubing. ”

“ APPLICABILITY: The working range is 16 to 450 mg/m 3 (5 to 150 ppm) for a 50-L air sample. During sampling, high humidity may greatly decrease the breakthrough volume.
INTERFERENCES: None identified.
OTHER METHODS: This is Method S70 [2] in a revised format.

EQUIPMENT:
Tetrahydrofuran, chromatographic quality. Glycidol, reagent grade.* Nitrogen, purified. Hydrogen, prepurified. Air, filtered. ”

“ Inject sample aliquot manually using solvent flush technique or with autosampler. NOTE: If peak area is above the linear range of the working standards, dilute with tetrahydrofuran, reanalyze and apply the appropriate dilution factor in calculations. ”
