&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;== Summary ==&lt;br /&gt;
The calculated CO fraction accumulates more rapidly during the higher-concentration interval. Based on Purser (2002), pp. 2-102–2-103.&lt;br /&gt;
&lt;br /&gt;
Original illustration for [[Fractional effective dose]], level 3 Advanced.&lt;br /&gt;
&lt;br /&gt;
* Source basis: Purser (2002), pp. 2-102–2-103, equation 7; selected illustrative exposure history.&lt;br /&gt;
* Alt text: The CO concentration rises after two minutes and the cumulative dose curve becomes steeper, ending at 0.144.&lt;br /&gt;
* Accuracy notes: Do not identify the endpoint as a probability, full fire FED, or safe exposure; no other hazards are included.&lt;br /&gt;
