Tests in which the contribution of wall linings of PVC to the fire hazards presented by traditional combustible material (wood) are reported.
PVC linings in a compartment did not significantly change maximum fire gas temperatures, or smoke density, but increased the overall outputs of heat and smoke. Their main contribution was to the toxic gases by the addition of hydrogen chloride to the carbon monoxide from the combustion of wood.
PVC wall paper and cloth did not contribute much to the hazard from a wood fire in a compartment. However PVC in a corridor could lead to the discharge of larger concentrations of hydrogen chloride.
