G. Newstead]. Edmonton : Northern Forest Research Centre, 1981. 4 p. Forest management note ; 9 Caption title. "July 1981." Digitized edition from print. "Water-gelling agents have been in use in forest fire control since the early 1960s. Several water additives ranging from swelling clays to organic and synthetic polymers have been developed and marketed as short-term forest fire retardants. These products have the ability to increase the viscosity of water so that, when applied to forest fuels, it absorbs more heat energy and the fuels are sealed off from the supply of oxygen. In this manner viscous water is more effective than plain or untreated water as a retardant."--P. [1]. gccst Forest fires gccst Fire prevention gccst Forest management Newstead, R. G. Canada.
