| Abstract: | The overall flammability hazard of Zirpro wool protective clothing, carpets and upholstery with regard to national and international standards is summarized. Protective clothing against heat and flames has to be evaluated not only for flame-retardance by a vertical flame test but also for heat transfer from convective (flames), radiant and conductive (molten metal) heat exposure to ensure a realistic assessment of the potential protective offered and required. Textile furnishings (carpets, upholstery, curtains) have to be evaluated for flame-retardance, heat release, smoke emission and toxicity of combustion products to assess the overall flammability hazard. Evaluation and consideration of only on e flammability parameter, e.g. toxicity of combustion products, can lead to misleading conclusions about the flammability hazard of a material. |
