“ SPECIAL PRECAUTIONS: Benzene is a suspected human carcinogen. All work should be performed in a hood. SAMPLING: 1.Calibrate each personal sampling pump with a representative sampler in line. 2.Break the ends of the sampler immediately before sampling. Attach sampler to personal sampling pump with flexible tubing. 3.Sample at an accurately known flow rate between 0.01 and 1 L/min for a total sample size of 16 to 100 L. 4.Cap the samplers with plastic (not rubber) caps and pack securely for shipment. SAMPLE PREPARATION: 5. ”

“ Allow to stand 30 min with occasional agitation. CALIBRATION AND QUALITY CONTROL: 8.Calibrate daily with at least six working standards over the range 0.01 to 1.5 mg allyl chloride per sample. a. Add known amounts of calibration stock solution to benzene in 10-mL volumetric flasks and dilute to the mark. b. Analyze together with samples and blanks (steps 11 and 12) . c. Prepare calibration graph (peak area vs. mg allyl chloride) . 9. ”
