- Abstract
- Millions of gallons of forest fire retardants are dropped on wildland fires every year. For both tactical effectiveness and cost effectiveness the retardant must be properly formulated and prepared. Retardants in use have been subjected to laboratory testing wherein the performance of properly mixed retardant is measured and evaluated. Retardants should also be tested in the field to assure that certain critical characteristics are being maintained. The Guide describes many long-term fire retardant products, their physical/chemical properties, and step-by-step procedures and instructions for measuring retardant properties in the field. Some of the retardants included in the Guide may not be approved for a specific agency's use as a result of varying policies. Calibration and conversion tables for each product are included in the Guide.
