The total imposed loads on the front and rear axles shall be computed by the contractor and
verified by the Government, using the curb weight, the operator and passenger weight at

shall be delivered by nozzles operating at not less than 25 pounds per square inch (psi) water
pressure. The nozzles shall be sufficient in number and placed approximately 4 feet from the
body to afford full coverage of sides, roof, front, rear and undercarriage of the body. The spray
