Healthcare facilities undergoing renovation have specific concerns that are exacerbated when the restoration requires asbestos abatement of aged floor tile and mastic. The current state of the art for removal of these materials involves manual removal of floor tile and chemical stripping of mastic. Utilization of these stripping chemicals is a concern for facilities whose perception is based on a safe, caring, and healthy environment. In this study, wet grinding is evaluated as an alternative to chemical stripping of asbestos-containing floor tile mastic. This study endeavors to answer the question; what is the difference between these two methodologies in terms of their operational efficacy and suitability in the healthcare setting. Wet grinding and chemical stripping are evaluated in a side-by-side comparison using a mixed methods approach. The data shows that the methodologies are statistically similar in terms of their cost and emissions data. The data indicates that the benefits associated with the wet grinding method offer advantages that are not present using the chemical stripping method. This study also demonstrates that wet grinding is a viable alternative to chemical stripping especially in healthcare facilities.
正在翻新的医疗机构有一些特殊的问题,如果需要清除旧的地板瓷砖和胶泥中的石棉,这些问题会更加严重。目前,这些材料的去除方法涉及手动去除地板瓷砖和化学剥离胶泥。对于那些认为环境安全、关怀和健康的设施来说,使用这些剥离化学品是一个问题。在这项研究中,湿磨被评估为一种替代含有石棉的地板瓷砖胶泥的化学剥离方法。本研究旨在回答以下问题:在医疗环境中,这两种方法在操作效果和适用性方面有何区别。湿磨和化学剥离在混合方法的对比研究中进行了评估。数据表明,这两种方法在成本和排放数据方面具有统计学上的相似性。数据表明,湿磨方法带来的好处与化学剥离方法带来的好处不同。本研究还表明,湿磨是化学剥离的一种可行替代方法,特别是在医疗机构中。
