• Description:
  The U.S. Bureau of Mines performed experiments to determine the embedded hydrogen chloride (hcl) and smoke particle characteristics during combustion of polyvinyl chloride (pvc) and chlorinated mine materials for development of a test parameter. The experiments were conducted in an approximately 20-l furnace at set furnace temperatures of 250 deg. and 1,000 deg. C, for a 14-min duration, with an airflow through the furnace of 10 l/min. The variables studied, as a function of time, were hydrogen chloride embedded on smoke particles, hydrogen chloride concentrations in the gas phase, smoke particle average diameter (dg) and concentration (no), and product of smoke particle diameter and concentration (dgno). Other variables included carbon monoxide (co), carbon dioxide (co2), and oxygen (o2) concentrations; sample mass weight loss; and furnace temperatures. Results show that there is a correlation between embedded hydrogen chloride, hydrogen chloride gas concentrations, and inverse of the smoke particle diameter-concentration product (1/dgno); the higher the hydrogen chloride gas concentrations, the higher the embedded hydrogen chloride, the higher the 1/(dgno) values. These correlations will enable development of a simple test parameter to assess the toxic hazard that these materials pose during fire. [Description provided by NIOSH]
