Heating Ventilating and Air Conditioning (HVAC)

Definition - What does Heating Ventilating and Air Conditioning (HVAC) mean?

Heating, Ventilation and Air Conditioning (HVAC) are responsible for the creation of comfortable interior environments. Employers are responsible for ensuring that HVAC systems supply adequate ventilation in accordance with the guidelines formulated by the American Society of Heating, Refrigeration and Air Conditioning Engineers (ASHRAE) in order to prevent the buildup of indoor pollutants that may be detrimental to the health of workers. In addition, these systems require regular maintenance in order of prevent the buildup of mold which may cause respiratory illnesses or allergies in workers.

Safeopedia explains Heating Ventilating and Air Conditioning (HVAC)

HVAC systems should not only ensure comfortable temperatures, but also allow for the introduction of sufficient fresh air to combat sick building syndrome and building related illness. Contaminants such as acetic acid, carbon dioxide, carbon monoxide, formaldehyde, nitrogen oxides, ozone, radon, volatile organic compounds (VOCs), miscellaneous inorganic gases, asbestos, synthetic fibers, tobacco smoke and microbials, as well as any other pollutants must be dealt with. The maintenance of healthy temperatures and humidity levels are also determined by HVAC systems and their maintenance. No specific indoor air quality (IAQ) parameters are prescribed by OSHA, but IAQ guidelines have been formulated by the EPA and NIOSH.
