At this time, there is no evidence that a building’s ventiliation system, in good operating condition, is contributing to the spread of the virus.
School districts are required to ensure that heating, ventiliation, and HVAC (air conditioning) systems are designed, operated, and maintained as per standards and specifications for ongoing comfort of workers. The WorkSafeBC website has an FAQ on ventilation.
(See page 21 of the updated “Provincial COVID-19 Health & Safety Guidelines for K-12 Settings.”)
Please bring your safety concerns to your site health and safety committee.
