Renovation of MSU/CVM Cage Wash Facilities: G20 Facilities Improvement Grant Appl

描述（由申请人提供）：密西西比州立大学的兽医学院（CVM）研究计划旨在维护和提供持续改进的动物饲养设施，设备和辅助支持设施。一个设计合理的笼子清洗区，一个可靠、高效的笼子清洗机，可以满足机构的需要，并且对工作人员来说是安全的，这是任何有效的动物护理和使用计划的基础。研究翼1A的笼清洗设施配备了一台23年的单门Basil RW4600笼清洗机，平均每21.6天就会发生一次故障，导致每年的维修费用超过13，000美元。由于原始制造商已被另一家公司购买，因此获得零件往往很困难且耗时。笼清洗区的频繁故障导致笼卫生延迟，这可能会影响研究项目的时间安排。对当前使用情况的分析表明，根据每天工作9小时，每年工作365天，笼式洗衣机以大约8%的容量运行。虽然目前还没有满负荷运行，但预计我们的工作人员使用笼式洗衣机的增加可能会增加故障的数量，从而增加未来几年的维护成本。目前的笼清洗区不能充分将干净的笼与脏的笼分开，没有令人满意的交通模式，没有垫料倾倒站，没有足够的通风，能源效率不高，并且没有确保安全工作环境的现有安全特征。基本纠正措施，即，更换老化的笼式清洗机，重新设计不方便的设施，并增加一个垫料倾倒站，将最大限度地减少当前和未来的生物防护问题，减少工人暴露于过敏原，创造一个环境可控的工作环境，并减少执行这些任务所需的能源。

DESCRIPTION (provided by applicant): Mississippi State University's College of Veterinary Medicine (CVM) research program seeks to maintain, and provide continuous improvement to animal holding facilities, equipment and ancillary support facilities. A properly designed cage wash area, with a reliable, efficient cage washer that can meet institutional needs and that is safe for personnel to operate and work near is fundamental to any effective animal care and use program. The cage wash facility on Research Wing 1A is equipped with a 23 year old single door Basil RW4600 cage washer that routinely breaks down on average every 21.6 days, resulting in annual repair costs of over $13,000. Because the original manufacturer has been purchased by another company, it is often difficult and time consuming to obtain parts. Frequent breakdowns in the cage wash area result in delays in cage sanitation, which then may affect research project timing. An analysis of current usage revealed that the cage washer is operated at approximately 8% of capacity, based upon a 9 hour work day, 365 days/year. Though not presently operating at full capacity, an anticipated increase in cage washer use by our staff will likely increase the number of breakdowns and, therefore, maintenance costs in the coming years. The current cage wash area does not adequately separate clean cage storage from dirty, does not have a satisfactory traffic pattern, does not have a dumping station for bedding, does not have adequate ventilation, is not energy efficient, and does not have current safety features to ensure a safe work environment. Fundamental corrective action, i.e., replacement of the aged cage washer, redesign of awkward Facilities, and addition of a bedding dumping station will minimize current and future biocontainment concerns, reduce exposure of workers to allergens, create an environmentally controlled work environment, and reduce the energy necessary to perform these tasks.
