Various samples of cellulose insulation were evaluated for relative toxicity of pyrolysis gases, using the toxicity screening test method developed at the University of San Francisco. The samples included un treated cellulose insulation and insulation treated with various levels of boric acid, 5-mol borax, and mixtures of boric acid and 5-mol borax. Relative toxicity appeared to decrease with increasing content of fire retar dant additive, but the change was not significant at the lower additive levels.
