Summary

The calculated CO fraction accumulates more rapidly during the higher-concentration interval. Based on Purser (2002), pp. 2-102–2-103.

Original illustration for Fractional effective dose, level 3 Advanced.

  • Source basis: Purser (2002), pp. 2-102–2-103, equation 7; selected illustrative exposure history.
  • Alt text: The CO concentration rises after two minutes and the cumulative dose curve becomes steeper, ending at 0.144.
  • Accuracy notes: Do not identify the endpoint as a probability, full fire FED, or safe exposure; no other hazards are included.
