Winter is notorious for the cold and flu season, which can cause what is known in the maintenance world as “sick building syndrome.” As indoor air quality worsens, bacteria, viruses, and mold can spread through the HVAC system of a facility and cause everyone in the building to feel sick.

Be careful where you source these materials, as overexposure to VOCs can cause long-term respiratory damage.

Carbon monoxide is also deadly if inhaled and can come from defective heaters, so be sure to test your facility for these gases and install a CO monitor to prevent injury or death.
