A New Cage Wash for Laboratory Animal Resources at Iowa State

项目总结/摘要 本申请的总体目标是继续履行提供高质量健康产品的使命。 动物的研究，教学和测试，确保照顾和使用动物符合指南 实验动物的护理和使用，并为使用或护理实验动物的人员提供安全和健康的工作场所。 动物以及保持AAALAC认证的兽医学院。学院 自2011年以来，兽药已获得AAALAC认证。爱荷华州的承诺 大学的高水平的动物护理是由我们持续的CVM AAALAC认证的支持。 该项目是安装一个新的笼式洗衣机，以取代一个31岁的单位，已达到 其使用寿命的结束。这个笼子洗服务30名教师从各个部门和学院，所有的 在中环或A翼动物设施饲养动物的人士。在2020年我们最近的一次现场访问中，AAALAC 声明“必须消除截留的可能性，并且在笼式/机架式垫圈的情况下，理想情况下， 紧急关闭机构，可从机器内的任何地方轻松接近， 当启动时，洗衣机应处于适当位置”。根据AAALAC立场声明， 建议将断电器电线放置在笼清洗的两侧。我们的笼子太旧了 很难找到一个供应商来用第二个断电器线来改造这种笼式清洗机。我们 下一次AAALAC现场访问将于2023年6月进行，因此为了保持我们的AAALAC认证并提供安全的 我们必须购买一个新的笼子清洗， 两条断电器电线拟议的新笼洗将防止昂贵的停机时间时，目前过时的 这将大大降低运营成本和用水量。这些设施容纳各种 用于教学和研究项目的物种，包括猪，狗，兔，猫，仓鼠，豚鼠， 牛、绵羊、山羊、雪貂、鸡和啮齿动物。 新的笼清洗机将安装在中央动物设施，该设施为中央和A- 翼动物设施。这种“绿色”模式将减少40%的冷热水消耗。新笼子 清洗机将提供一个可靠的服务，笼清洗，并将消除维修费用和损失的天数 经常使用当前的笼式洗衣机。最重要的是，它将确保适当的消毒， 设备，有助于改善动物健康并减少由于设备携带的污染物而产生的研究变量。 更换使用了31年的现有笼式垫圈的重要性非常重要。新的笼子清洗将有一个 更长的内部腔室，使我们现在可以清洁大型动物围栏，这是在过去手动清洁。

Project Summary/Abstract The overall objective of this application is to continue the mission of providing high quality healthy animals for research, teaching and testing, assuring care and use of animals consistent with the Guide for the Care and Use of Laboratory Animals, and provide a safe and healthy workplace for personnel who use or care for animals as well as maintaining AAALAC accreditation for the College of Veterinary Medicine. The College of Veterinary Medicine has been AAALAC accredited since 2011. The commitment of the Iowa State University to a high level of animal care is supported by our continued CVM AAALAC Accreditation. This project is for the installation of a new cage washer to replace a 31-year-old unit that has reached the end of its useful life. This cage wash services 30 faculty from various departments and colleges, all of whom have animals in Central or A-Wing animal facilities. During our most recent site visit in 2020, AAALAC stated that “the possibility of entrapment must be eliminated, and in the case of cage/rack washers, ideally an emergency shut-off mechanism that is easily accessible from anywhere inside the machine and which de- energizes the washer when activated should be in place”. Per the AAALAC position statement, it is recommended that de-energizer cords are placed on both sides of the cage wash. Our cage wash is so old that it has been difficult to find a vendor who will retrofit this cage wash with a second de-energizer cord. Our next AAALAC site visit will be in June of 2023, so to keep our AAALAC accreditation and to provide a safe working environment for our employees it is imperative that we purchase a new cage wash that comes with two de-energizer cords. The proposed new cagewash will prevent costly downtime when the current outdated model fails and will reduce operating costs and water usage significantly. These facilities house a variety of species used in teaching and research projects, including swine, dogs, rabbits, cats, hamsters, guinea pigs, cattle, sheep, goats, ferrets, chickens and rodents. The new cage washer will be installed in Central Animal Facility, which services both Central and A- Wing animal facilities. This “green” model will reduce hot and cold-water consumption by 40%. The new cage washer will provide a reliable service for cage washing and will eliminate the cost for repair and days of lost use that occur regularly with the current cage washer. Most importantly, it will ensure proper sanitization of equipment, helping to improve animal health and reduce research variables due to equipment borne fomites. The importance of replacing the 31-year-old current cage washer is significant. The new cage wash will have a longer internal chamber, allowing us to now clean large animal penning that was cleaned manually in the past.
