Refers to cleaning the work space on a regular basis of dust, dirt, tools and wastes. If the lab space is wiped down at the end of every shift, then not only will the lab space look better, but the lab space will remain in better condition. If cleaning is not performed on a regular basis within a lab, then things such as accumulation of wastes, dirt, chemicals and equipment can become an overwhelming obstacle requiring more man hours to accomplish than with regular cleaning.
