A New Cage Wash for Laboratory Animal Resources at Iowa State

项目摘要/摘要 该应用程序的总体目标是继续履行提供高质量健康服务的使命 用于研究、教学和测试的动物，确保照顾和使用动物符合《动物保护指南》 照顾和使用实验动物，并为使用或护理人员提供安全和健康的工作场所 以及保持AAALAC对兽医学院的认证。书院 兽医部自2011年以来一直获得AAALAC认证。爱荷华州政府的承诺 大学动物护理的高水平是由我们持续的CVM AAALAC认证支持的。 该项目是为了安装一个新的笼式垫圈，以取代一个已有31年历史的装置，该装置已达到 它的使用寿命结束了。这个笼子洗涤器为来自不同系和学院的30名教职员工服务，所有 他们在中环或A翼的动物设施中有动物。在我们2020年的最近一次现场访问中，AAALAC 声明“必须消除困住的可能性，在笼式/架式垫圈的情况下，理想的情况是 紧急关闭机构，可从机器内部的任何位置轻松操作，并可降低 当被激活时，给垫圈通电应到位“。根据AAALAC立场声明，它是 建议在保持架清洗的两侧放置减能器电源线。我们的笼子洗涤器太旧了 很难找到一家供应商将这个笼式洗涤器改装成第二根断电电源线。我们的 下一次AAALAC现场访问将于2023年6月进行，以保持我们AAALAC的认证并提供安全的 为我们的员工提供工作环境，我们必须购买一个新的笼式洗涤器 两根减能器电线。拟议的新Cagewash将防止当前过时的代价高昂的停机时间 这种模式失败了，将显著降低运营成本和用水量。这些设施容纳了各种各样的 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。 新的笼式垫圈将安装在中央动物设施，该设施为中环和A区提供服务- 机翼动物设施。这种“绿色”模式将减少40%的冷热水消耗。新笼子 垫圈将为笼子清洗提供可靠的服务，并将消除维修成本和丢失天数 使用当前笼式垫圈经常出现的垫圈。最重要的是，它将确保适当的卫生 设备，有助于改善动物健康，减少由于设备携带的杂物而产生的研究变量。 更换已有31年历史的笼式垫圈具有重要意义。新的笼式洗涤器将有一个 更长的内室，允许我们现在清洁大型动物围栏，过去是手动清洁的。

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.
