PHOS-CHeK D75 Fire Retardants
PHOS-CHeK D75 Fire Retardants are highly soluble powders that mix readily with water by recirculation, agitation or PHOS-CHeK eductor-mixer systems. PHOS-CHeK D75 ﬁre retardant solutions are high viscosity gum thickened providing highly effective and accurate aerial drop characteristics. Minimizing drift and evaporation, they are ideal for safe drop height applications providing effectiveness and accuracy from several hundred feet above the fuel. The elastic nature of the thickener in PHOS-CHeK retardants facilitates increased fuel coverage, wrap around and penetration through canopy and ladder fuels to ground vegetation.
PHOS-CHeK D75-R is red in color to provide maximum visibility for an application. Fugitive colored D75-F maintains visibility during application but faded to an earth tone after exposure sunlight. This prevents permanent staining in sensitive areas including national landmarks and in the urban wildland interface.
PHOS-CHeK D75 Fire Retardants are qualiﬁed by the USDA Forest Service for use in ﬁxed-wing air tankers and helicopters with buckets.
D75 is specially formulated for use in multi-engine ﬁxed-wing air tankers, single engine air tankers (SEATS). D75 is available in Red Iron Oxide (R) and Fugitive (F) color.
PHOS-CHeK Fire Retardants are used for wildland ﬁre control in forest, brush or grassland. Functionally, PHOS-CHeK Retardants react with and alter the decomposition of wildland fuels so that they do not support ﬂaming or glowing combustion. This deprives the ﬁre of fuel reducing ﬁre intensity and the rate of ﬂame spread.
PHOS-CHeK Australia maintains the inventory of D75R in Phos-bins. This high viscosity product is ideally suited to fixed wing application and building line in eucalypt forest, typical of south eastern Australia.
