Do you know what’s in the air you and your staff breathe at work?

As the debate over indoor air quality (IAQ) and its impact on the health and wellbeing of building occupants gathers pace, we thought we’d examine some of the most common pollutants that staff and visitors in offices, hotels, restaurants and other occupied spaces are exposed to.

Biological

Pollutants such as bacteria, fungi, viruses and legionella thrive in areas where water is found, which is why the moist environment of an air handling unit (AHU) within an HVAC system is such a common breeding ground for contaminants. Other biological pollutants include dust mites and animal dander, which may aggravate allergies in some building occupants.

Chemical

Airborne chemical pollutants (gases and vapours) include can cause nausea, headaches, irritation to the eyes, nose and throat and respiratory infections such as bronchitis and pneumonia. Sources of such pollutants include:

  • Products used within the building such as fragrances and cleaning products
  • Polluted outside air pulled into the building by the HVAC system
  • Accidental spillages
  • By-products of combustion including carbon monoxide and nitrogen dioxide

Particles

Most commonly, airborne particles of dust and dirt enter a building’s ventilation system from outside. Nearby construction can also result in silica dust from the drilling, cutting or grinding of rock, masonry and concrete being drawn in by a building’s HVAC system. These tiny particles, if inhaled by building occupants, can have serious long-term implications such as respiratory disorders, lung cancer and heart disease.

Gibbons Ultraviolet Solutions, in association with BioZone Scientific International, has designed a range of ultraviolet-C (UVC) light systems that destroy contaminants in the air and on surfaces within occupied spaces.

These ultraviolet germicidal irradiation (UVGI) systems can be installed in buildings such as offices, health facilities, hotels and swimming pools, helping facilities managers to improve the health, wellbeing and productivity of occupants.

One such system from Gibbons Ultraviolet Solutions is CoilCare®, which is mounted within an AHU to apply UVC light to the cooling coil. This destroys pollutants that thrive there, allowing building occupants to breathe clean, germ-free air.

Continued use of the low-maintenance CoilCare ® system prevents contaminants from accumulating again, giving peace of mind to building managers, staff and visitors alike.
