“ Tetranitromethane is highly toxic and extremely explosive [3] . Use fume hood and protective equipment. SAMPLING: 1. 2. 3. 4. 5. Calibrate each personal sampling pump with a representative sampler inline. Pipette 15 mL of ethyl acetate into each impinger. Attach midget impinger to personal sampling pump with flexible tubing. Sample at an accurately known flow rate of 0.5 to 1.0 L/minute for a total sample size of 20 to 250 L. NOTE: Routinely check and fill impingers to insure that the level of ethyl acetate remains at a volume of 10 to 15 mL. Transfer the sample solution to 20-mL vial. ”
