Office Ventilation

Office ventilation
Virtual Office Flash introduction – Ventilation
Objects Hazards Possible controls
Air flow
  • Insufficient volume of air through the area
  • Arrange for rate of air flow to be measured and if necessary increase
  • Ensure placement of air-conditioning vents is appropriate to allow adequate air flow (i.e. within enclosed offices)
Air temperature
  • High or low indoor air temperatures
  • Have temperature in affected area measured and adjustments made to stabilise temperature in the area in consultation with the effected workers
  • Look at location of workstations in relation to ducts and openings
  • High or low levels of relative humidity in workplace
  • Have humidity in affected area measured and adjusted to the appropriate level in consultation with the effected workers
Atmospheric contaminants
  • Ozone may be released in small amounts by electrostatic photocopiers and printers
  • High levels of dust or other particles (e.g. pollen, printer emissions) in indoor air
  • Harmful levels of airborne contaminants (e.g. lead fumes, acid mist, solvent vapour) released by specific work processes
  • Ensure that filters are of the correct type to remove expected contaminants, and that filters are clean and are replaced regularly or as required
  • Avoid continuous photocopying and collating or ensure adequate breaks are taken
  • Consider moving printer and photocopiers to a designated printer room
  • Ensure local control measures such as exhaust ventilation are in place to remove contaminants at the source
  • Odours and airborne contaminants entering building from the street
  • Excess accumulation of odours inside the workplace

  • Implement a smoking policy to ensure workers and visitors do not smoke near access points or ventilation intakes
  • Consult with other relevant people in relation to smoking guidelines around the building
  • Utilise air-conditioning, ventilation systems and extraction units to ensure the air is adequately ventilated and excess odours removed from the workplace
Disease control
  • Spread of harmful bacteria via central air-conditioning system (e.g. Legionnaire disease)
  • Ensure that air-conditioning equipment is being serviced in accordance with manufactures instructions
  • Ensure that checks are being carried out for the detection and measurement of harmful bacteria
