<p>Watermark: Fire Safety Academy logo icon, 70 px, 45 % opacity</p> <p><b>New page</b></p><div>== Summary ==<br /> Dose needed for incapacitation against concentration: nearly constant for carbon monoxide, as Haber&#039;s rule predicts, but falling steeply for hydrogen cyanide. Based on Purser (2002), pp. 2-88 and 2-105.<br /> <br /> Original illustration for [[Haber&#039;s rule]], level 4 Expert.<br /> <br /> * Source basis: Purser (2002), p. 2-88 (Figure 2-6.5 caption values), p. 2-104 (constant 27,000 ppm·min for CO; about 2000 and 400 ppm·min for HCN at 100 and 200 ppm) and p. 2-105 (Equation 9, valid range about 80 to 180 ppm and above). New chart; do not copy Figure 2-6.6.<br /> * Alt text: Two charts of dose to incapacitation against concentration: flat for carbon monoxide, falling steeply for hydrogen cyanide.<br /> <br /> == Licensing ==<br /> New drawing by Fire Safety Academy. © Fire Safety Academy.</div>
