Introduction： There are several com.onents in m.tion before steam.reaches its destination. Each elem.nt plays a significant role in generating adequate steam.for term.nal sterilization of critical devices. The knowledge and awareness of factors that contribute to wet packs will assist in m.xim.zing steam.quality. Steam.sterilization of critical devices such as surgical instrum.nts in the acute care setting is fundam.ntally necessary to prevent infection. Sterile packaging that is wet after rem.val from.the autoclave is considered contam.nated. This wet pack presents a significant infection risk and indicates a defect in the sterilization process. The identification of wet packs prom.ted the exploration of the sterilization process. In reviewing the evolution of steam.production, our investigation began in the boiler room. The assessm.nts of the boiler operations, steam.quality, and loading technique of the autoclaves were exam.ned as possible contributing factors in the propagation of wet packs. m.thods： The investigation was perform.d in a 592-bed non-teaching acute care facility in New Jersey. m.thods to ensure the integrity of steam.included; a cut point of 〈 3,500 ppm.TDSs （total dissolved solids）, （daily） calibration of the TDS analyzer to ensure accurate TDS m.asurem.nt, increase in autoclave drying tim.s, reduction of the weight density of surgical trays from.25 lbs. to 20 lbs., and revision of sterilization loading practices. m.difications were im.lem.nted from.June 2015 to Decem.er 2015. Results： No wet packs were identified from.January through m.y 2016. In June 2016, 2 wet packs were detected, and upon further analysis there was an increase in the water level of the boiler drum. After this special cause variation, no wet packs have been identified. Conclusion： The m.nitoring and docum.ntation of boiler room.param.ters and CSP （central sterile processing） practice m.difications m.y have im.acted the reduction of wet pack.
