Coronavirus Disease 2019 (COVID – 19) is an acute respiratory disease caused by a novel Coronavirus (SARS-CoV-2), transmitted in most instances through respiratory droplets, direct contact with cases and also through contaminated surfaces/objects.
Though the virus survives on environmental surfaces for varied periods of time, it gets easily inactivated by chemical disinfectants. Thus emphasizing the importance of Deep Cleaning/Sanitizing surfaces.
While research into the COVID-19 virus is ongoing, we know the virus is transmitted through direct contact with respiratory droplets of an infected person (through coughing and sneezing), and touching surfaces contaminated with the virus. The virus may survive on surfaces for a few hours up to several days.
The National Department of Health has developed environmental health guidelines to address environmental health-related questions and gaps when responding to COVID-19. This concerns recommendations on the management of the deceased due to COVID-19 and the disposal of infected corpses; tracing of family, household hygiene, workplace and community contacts; cleaning, decontamination/disinfection in the workplace, household of patients and contacts; and other environmental factors.
The guidelines aim to guide Environmental Health Services (EHS) and the public on key roles related to the management of COVID-19. Some of the key recommendations on the Environmental Health Guidelines include decontaminating, sanitizing and disinfecting affected homes, office, work place, social and public environments.
Importantly, since COVID-19 rests on surfaces, cleaning, sanitizing and disinfecting industrial and commercial spaces are extremely important.

- Recommended cleaning and disinfection procedures should be followed consistently and correctly.
- Disinfection should be done on all surfaces and in all environments in which Covid-19 is or could potentially be present.
- It is vital that the disinfectant used be diluted to the recommended rate to achieve the desired outcome.
- Sanitizing activities should be carried out during off-peak hours to allow more contact time.
- Sanitizing of public places such as bus or taxi ranks and other open parking spaces should not be conducted during rainy or windy days as it may affect effectiveness of the disinfectant.
- It is recommended that Sanitizing be repeated monthly, even weekly if possible, as the sanitized area is rendered clean upon completion, but can be contaminated by external factors afterwards or during use.
- Please note that all services which are frequently touched by personnel like door knobs, photo copy machines, reception desk, ash trays, bathroom services etc need to be cleaned with a sanitizer daily.
- Evacuation and removing of personal belongings should take place prior to work being executed. We will not be liable for any loss.
- Identify the most critical areas (possibly infected) as focus point for work to commence.
- A systematical approach will be taken by identifying the most practical starting point in each room, (usually the highest point). In most cases cleaning will start with the walls and from there moving on to fixed and movable furniture (external surface areas only). Once that has been done, all movable furniture will be put back into place and the floor will then be fully disinfected moving from the furthest point in the room to the nearest door. This will be done by airless spraying of disinfectant on mentioned surfaces.
- Lastly all doors and handles will be disinfected.
- A certificate will be placed on the door/entrance when area has been completely disinfected.
- 70% Ethyl Alcohol to disinfect small areas between uses, such as reusable dedicated equipment. (example, telephones, thermometers, clocking machines etc.)
- Disinfectant or antiseptic solution (with the following ingredients: Alkyl Dimethyl benzyl ammonium chloride and poly hydrochloride) and Chlorine releasing agent – hypochlorite (strength: 1000-10,000 ppm) are highly recommended as they provide deep cleaning and surface cleaning of the areas, and effective against bacteria, fungi, viruses and spores
