pa * SEEon) Project 2.8 - Shipboa.d Countermeasures Methods Studies - P. H. Heiskell To determine the relative effectiveness of various proposed shiend personnel orotection cnd reclamation methods. RESCHIPTICN AND _EXP*PIMPNTAL PROCSCURE These studies coneisted of & probleme to be carried out on the YaG-39 and YAG-40 and at the Rad Sefe center on Parry. These & tro- blems involwe: the study of the effectiveness of various shipboard oretective methodr, d-contarinetion methods, hazerd assescment methods, personnel =rotection end decontamination methode, and basic contamineabllity-decontsminabdility, RESULTS ANE CONCLUSIONS The excerimental hot water sensitive vaint (FR°C) used in these tests was not setisfectory froe e durability and weatherability stand- point, however it wos successful from the stand-oist of removatility anc decontnminebility. Pemovel rates varied from 1D s usre feet ver minute using 6 1250 ¢-h hot livuld jet univ to ar-roximately “O s.usare feet :er minute using a 6000 prh unit. Prior firehosing removed 87 percent of the oontaminent and the atrio-ing cf the RRC removed a:rroximately 8&5 vercent of thie reeidual, for en ovcrall removal of 98 cercent. Stri--ing of che FRPC without firehosing removed 95 rercent of the contaminant. The decontemini tion effectivenees of the mechanical brust. was found to be inferior to manual brushine. The wanucl ecrubting demended in this test was very virorous and after a matter of minutes the men tired.
