Spill response procedures are an important aspect of laboratories where infectious materials are handled. The decades-old conventional method of spill cleanup uses paper towels to cover the spill. It requires 2 staff and involves a considerable amount of bending and squatting and being able to balance in those positions while wearing personal protective equipment (PPE). In this article, we describe a method that simplifies spill cleanup and compares it to the conventional method. The simplified method can be easily conducted by 1 person, takes about half the time, generates less waste, and reduces the amount of time spent in contaminated areas.
The objective is to describe a modified, simple method of spill cleanup.
A mock spill was created and a spill response initiated per the institution's procedure. The simplified procedure uses a pail filled with decontaminant and a household mop dripping with the decontaminant. Mopping is done from the noncontaminated area toward the contaminated area so the spill does not spread. Mopping is done more than once, and all the materials used, including the mop(s), are disposed as biohazardous material.
The simplified spill cleanup process described here can be performed by just one person and does not require bending and squatting while wearing PPE. The kit is very simple, consisting of a pail and a mop, which are common household tools familiar to most people.
The mop-and-pail methodology is simple, requires only one staff member, generates less biological waste, and requires less training and practice while effectively cleaning the spill.
溢出物应对程序是处理感染性材料的实验室的一个重要方面。数十年的传统溢出物清理方法是用纸巾覆盖溢出物。这需要两名工作人员,并且涉及大量的弯腰和下蹲动作,同时还要在穿着个人防护装备(PPE)的情况下保持这些姿势的平衡。在本文中,我们描述了一种简化溢出物清理的方法,并将其与传统方法进行比较。这种简化方法一人即可轻松操作,耗时约为传统方法的一半,产生的废物更少,且减少了在污染区域停留的时间。
目的是描述一种改进的、简单的溢出物清理方法。
制造一次模拟溢出,并按照机构程序启动溢出物应对措施。简化程序使用一个装满去污剂的桶和一把浸有去污剂的家用拖把。从无污染区域向污染区域拖地,这样溢出物就不会扩散。拖地要进行多次,所有使用过的材料,包括拖把,都作为生物危害材料处理。
这里描述的简化溢出物清理过程仅需一人即可完成,且在穿着PPE时无需弯腰和下蹲。清理工具非常简单,由一个桶和一把拖把组成,这是大多数人都熟悉的普通家用工具。
拖把 - 桶清理方法简单,仅需一名工作人员,产生的生物废物更少,所需的培训和练习也更少,同时能有效清理溢出物。
