Final answer:
The question refers to maintenance and custodial activities that involve contact with ACM or PACM without disturbing them, mainly for cleaning purposes in a building environment.
Step-by-step explanation:
The activities described refer to maintenance and custodial tasks within a building environment. These tasks involve employees who may come into contact with Asbestos-Containing Materials (ACM) or Presumed Asbestos-Containing Materials (PACM) when performing their duties, such as cleaning up dust, waste, and debris. However, these tasks do not involve physically disturbing the ACM or PACM, which would require special procedures to prevent asbestos exposure and comply with health and safety regulations.
