fire hazard assessments must be primarily driven by life safety variables. Concern is often highly focused on toxicity issues, since fire deaths, in the majority of cases, are found (in whole or in part) to be due to toxic gas inhalation. Procedures have recently been published by ISO, wherein the toxicity assessment of fire products is focused primarily On bench-scale testing for toxic potency (the 'per-gram toxicity'). Yet hazards of products with regards to fire toxicity May be determined much more by their differences in burning rates than by any differences in toxic potency. Burning Rates are not assessed in the pertinent standards (ISO 13344 and ISO TR 9122).
