COVID-19 is transmitted by close contact and respiratory droplets thus it is critical to mitigate this risk by monitoring the internal air quality. According to SS554, high carbon dioxide levels, more than 700 ppm in excess of outdoor level, indicates poor ventilation or overcrowding. In view of the current COVID-19 situation, premises owners should achieve lower levels.
