IS YOUR BUSINESS COVID-19 READY?

GUIDELINES FROM THE GOVERNMENT

The purpose of this guideline is to provide basic guidance on the ventilation of workplaces for the control of covid-19 transmission. The focus of this guideline is to understand how to prevent long range infection.

How to prevent long range infection?

EXPOSURE CAN OCCUR IN THREE PRINCIPAL WAYS:

  • Touching mucous membranes
  • Deposition of respiratory droplets
  • Inhalation of very fine respiratory droplets

The above animation explains how droplets transferred into airborne particles may increase the spread of Covid-19 related diseases in our daily environment.

Why do we need ventilation?

3 MAIN RISK FACTORS FOR LONG RANGE INFECTION:

  • Enclosed spaces with inadequate ventilation or air handling
  • Increased exhalation
  • Prolonged exposure under these conditions, typically more than 15 minutes.

Airconditioning Is Not Ventilation

AIRCONDITIONING IS NOT SYNONOMOUS WITH VENTILATION SINCE:

  • Air conditioning refers to the ability of the system to heat, cool and dehumidify.
  • Air conditioning systems are not automatically ventilation systems.
  • Importantly, most split unit aircons do not have ventilation capability, and must be combined with some sort of ventilation (most commonly natural ventilation).

How much ventilation is required?

Minimum ventilation rates for occupied spaces in south african buildings are prescribed by the compulsory standard sans 10400-o: 2011. However, in the context of long-range sars-cov-2 transmission control, the world health organisation recommends that each room is supplied with at least 10 l/s/person (litres of fresh outdoor air every second per room occupant)

Is there adequate ventilation?

THERE IS INADEQUATE VENTILATION IF:

  • The room feels stuffy
  • If the room has only an air – conditioner
  • Any room with closed windows

How to deliver ventilation?

NATURAL VENTILATION

WHY THIS IS NOT EFFECTIVE:

  • It is dependent on the wind direction
  • It mixes air particles within the room

Covid Efficient Ventilation

STACK VENTILATION

Stack ventilation is considered to be the most effective as hot air rises naturally.

Mechanical Ventilation

ISSUES WITH MECHANICAL VENTILATION :

  • Expensive
  • Operating costs
  • Maintenance costs
  • Limited fresh air supply
  • Power dependent
