Heating Ventilation and Air Conditioning (HVAC)

Explanation:

Heating, Ventilation, and Air Conditioning, HVAC, are air quality maintenance systems such as air conditioning system in our homes and in cars, large air conditioning systems used in industrial buildings and office complexes to give comfort and temperature control by the application of heat transfer, fluid mechanics and thermodynamic principles

HVAC systems actively replaces spent air in confined spaces by the addition of humidity and temperature controlled oxygen air and the removal  smoke, odors, CO₂, dust bacteria which are airborne, chemicals and other harmful gases and particles that would be otherwise inhaled.

The correct option is therefore;

A/n HVAC system control the concentration of toxic and hazardous materials in the air so that workers can have a safe working environment. It replaces the air in indoor spaces maintain air quality.
