Toxic Exposure Limits: Arsine
ERPG to NRC Vol1
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.
