Toxic Exposure Limits: Oleum
Toxic chemical exposure limits for hazardous gases and vapors, combining ERPG (Emergency Response Planning Guidelines: ERPG-1/2/3), IDLH (Immediately Dangerous to Life or Health), TLV-TWA (ACGIH Threshold Limit Value, time-weighted average), and NRC Spacecraft Maximum Allowable Concentration (SMAC) limits for 60-min, 24-hr, and 90-day continuous exposure. Covers ~49 chemicals under the ERPG framework and ~30 under NRC SMAC. Data from Perry's Chemical Engineers' Handbook 8th Ed., Tables 23-16 and 23-17.
| chemical name | exposure framework | cas number | erpg 1 (ppm or mg/m3) | erpg 2 (ppm or mg/m3) | erpg 3 (ppm or mg/m3) | idlh (ppm or mg/m3) |
|---|---|---|---|---|---|---|
| Oleum | ERPG | 8014-95-7 | 2 mg/m3 | 10 mg/m3 | 30 mg/m3 | LC50: 347/1 h |
