“…In addition, none of the fire retardants detracted from the CuN performance when used in combination with the preservative. The efficacy of these fire retardants as fungicides and insecticides is not surprising since organohalogen compounds such as pentachloro phenol, [50][51][52], DDT [53,54], dieldrin and lindane [24] are well-known insecticides as are organo-phosphorus compounds such as chlorpyrifos and pyridaphention [55][56][57][58]. Both chlorine-and phosphorus-based compounds were shown to be efficacious as fungicides in a study by Greaves et al [59] and the organic halogen fire-retardant compound, tetrabromobisphenol A, is known to impact upon biota [37].…”

SUMMARYIn this work, we co-formulated an oil-borne copper naphthenate/permethrin wood preservative system with synthetic polymer-based fire-retardant additives prior to the impregnation of Pinus radiata sapwood. We evaluated what effect, if any, the preservative had upon the fire performance properties of the fire retardants and whether the fire retardants impacted on the fungicidal and termiticidal efficacy of the preservative. The fire retardants included halogenated and phosphorus-based systems. A mass loss calorimeter, in conjunction with a thermopile, was used to measure the time to ignition and the peak heat release rate (PHRR) from which the fire performance index (FPI) was determined. The preservative properties were evaluated using termite and soil-block decay bioassays. In summary, we found that the rate of fire growth was reduced when the fire retardants were used in combination with the wood preservative. We also found that the PHRR was a better determinant of fire performance than the FPI. The performance of the wood preservative was enhanced against fungal decay and termite attack when used in combination with the fire retardants. The fire retardants also demonstrated some wood preservative properties of their own.
