Source: NIOSH Pocket Guide to Chemical Hazards, Sulfur dioxide (OSHA PEL from 29 CFR 1910.1000 Table Z as listed there). TWA = 8-hour time-weighted average, ST = short-term (15-minute), C = ceiling, Ca = NIOSH potential occupational carcinogen. NIOSH physical description: Colorless gas with a characteristic, irritating, pungent odor. [Note: A liquid below 14°F. Shipped as a liquefied compressed gas.]
Draeger short-term tubes are read on a Draeger accuro or X-act 5000 tube pump. Per the handbook (pp. 28–29), Draeger tubes and Draeger pumps are matched at the factory and form a single unit; other makers' pumps and tubes are not interchangeable with them. All Draeger tubes A–Z.
