Under the University of Pittsburgh protocol, mice are exposed to the products of combustion from a test sample; the sample weight at which 50% of the mice die determines the Lethal Concentration Number (LC<sub>50<\/sub>). In other words, the more material required, the less the toxicity &#8211; the higher the LC<sub>50<\/sub> value, the lower the toxicity. As a benchmark, Douglas Fir has an LC<sub>50<\/sub> value of 63.8 grams. ATS\u00e2\u0080\u0099 results:<\/p>\n<p style=\"text-align: center;\">ATS Intermediate Layer &gt; 283.8 grams<br \/>\nATS Exterior = 244.2 grams<br \/>\nATS Composite = 40.9 grams<\/p>\n<p>By comparison, other materials which are used in the fire-resistant, corrosion-resistant fume exhaust duct industry include:<\/p>\n<p style=\"text-align: center;\">Coated metal\u00e2\u0080\u0099s ETFE liner (Tefzel film)* = 7.3 grams<br \/>\nPolypropylene schwerentflammbar (PPs) (\u00e2\u0080\u009cFire Retardant\u00e2\u0080\u009d Version) = 8.0 grams<\/p>\n<p>The chart on this page shows the relative toxicity of the mentioned products in comparison to the ATS&#x2122; Duct Composite (ATS&#x2122; Duct = 1.0).
