Smoke toxicity of fire protecting timber treatments

Contemporary Fire Safety Engineering in Timber Structures: Challenges and Solutions

“…The smoke toxicity was assessed based on the asphyxiants CO and HCN as effective dose fractions for incapacitation. This work indicates that impregnated wood has a significantly higher anticipated smoke toxicity than coated wood when the fire reaches an under-ventilated stage, due to the large emission of carbon dioxide [111].…”

“…More smoke and higher toxic gas concentrations, such as carbon monoxide (CO), would be given off upon burning some fire retardants under high flashover heat fluxes [13]. The majority of fire-related deaths are caused by the inhalation of toxic gases [111]. Hansen-Bruhn et al [111] studied the fire toxicity of untreated wood, pressure-impregnated wood, and surface-coated wood under a series of fire conditions.…”

“…The majority of fire-related deaths are caused by the inhalation of toxic gases [111]. Hansen-Bruhn et al [111] studied the fire toxicity of untreated wood, pressure-impregnated wood, and surface-coated wood under a series of fire conditions. They replicated various fire stages using a steady-state tube furnace, sampled fire effluents and determined the yield of toxic products using High-Performance Ion Chromatography and Spectrophotometry.…”
