Optimized HVAC systems can help reduce exposure to COVID-19. The Department of Labor & Industries (L&I) just published “COVID-19 Guidance on Ventilation in the Workplace” – a one-page tip sheet on ventilation improvements that can be made to help provide a workplace free of safety and health hazards.
Coronavirus is a serious workplace health hazard. Adequate ventilation throughout the work environment can help to maintain a safe and healthy workplace.
Items that can be addressed to update HVAC systems include:
- Building owners and managers can work with an HVAC professional to optimize building ventilation.
- Document inspections performed, the findings of those inspections and the changes made.
- Replace air filters regularly, and look into ways to improve air filtration, including use of HEPA filters.
- Ensure exhaust fans in restrooms are set up properly, are fully functional, and are set to remain in constant operation.
- Change settings that shut systems down or reduce their use during off hours, so that air is continually circulated within the building.
- Set up the HVAC systems to bring in as much outside air as possible, avoiding recirculation of indoor air.
The tip sheet provides detailed instructions for these and other steps that can be taken to optimize HVAC systems in workplaces.
