4、es.1.4 This practice is one of four related to dispersant appli-cation systems using booms and nozzles.One is on design,oneon calibration,one on deposition,and one on the use of thesystems.Familiarity with all four standards is recommended.1.5 This standard does not purport to address all of thesafe
