Coronavirus (COVID-19) Decontamination

SASAC Decontamination Process and Standards

Imperative Service for COVID-19

During these uncertain times the decontamination of surfaces, equipment, air conditioning and ventilation ducts is essential to stop the spread of infectious diseases.

 

Research suggests that COVID-19 may remain viable for hours to days on surfaces made from a variety of materials. It is therefore very important that areas are properly cleaned and disinfected, air ducts and ventilation systems are also very important to be decontaminated as well as the change of the flow rate to curb the spread of the virus.

 

Cleaning of surfaces followed by disinfection is the best practice method to prevent the spread of COVID-19 and other viral respiratory illnesses.

Decontamination Process

There are 3 vital steps in the decontamination process:

1.    Cleaning:
Process that removes dirt, dust, large numbers of micro-organisms and the organic matter using detergent and warm water or disposable detergent wipes.
2.    Disinfectant
Process of removing or killing most, but not all viable organisms. The aim of disinfection is to reduce the number or micro-organisms to a level at which they are not harmful. Spores are destroyed by the disinfection process.
3.    Sterilisation:
Process of removing or killing all viable organisms including spores. Dead micro-organisms and toxins (pyrogens) may remain. Prions will not be effectively destroyed by this process.

Viral Definition

Pyrogens Definition:

Substance typically produced by a bacterium, which produces fever when introduced or released into the blood. 


Prions Definition:

Misfolded proteins with the ability to transmit their misfolded shape onto normal variants of the same protein. They characterize several fatal and transmissible neurodegenerative diseases in humans.
