From the Introduction:'To help ensure that the retardant costs are economical and that the products are effective, a formal evaluation is to be conducted at each fixed-wing retardant base. A basic premise is that fire retardant will be used in fire suppression work. The evaluation process will be used to determine the most cost-effective retardant product. Use of the Value Analysis process at locations using retardant in helicopters and/or ground application vehicles is optional. The amount of effort in such an undertaking would have to be commensurate with the potential savings.'
