Cleaning and Decontamination of Workplaces in the Context of COVID-19
Procedures for ‘deep cleaning’ may have emanated from the requirement published in the COVID-19 Disease: Infection Prevention and Control Guidelines of the Department of Health that stated “cleaning the environment is paramount” and the procedure to deep clean the environment is described in the Practical Manual for Implementation of the National Infection Prevention and Control (IPC) Strategic Framework.
However, this requirement is primarily for a specific area in the work environment that was occupied by a person who was diagnosed with COVID-19 to enable reoccupation of the affected area as soon as possible for essential services to resume. Deep cleaning involves cleaning walls, ventilation shafts and grills and storage areas, floors, windows, ceilings, etc in all clinical and non-clinical areas. In area/s where a person was tested positive for COVID-19, an incident-based risk assessment approach, as specified in the Department of Employment and Labour’s Direction and the Department of Health’s Guideline, need to be followed.
