Indoor Air Quality

People spend a large part of their day in the workplace and good indoor air quality is key to maintaining good health and wellbeing of building users. Poor indoor air quality can not only have a negative impact on the building user’s perception of the workplace, but also impact their health through work related illnesses. Immediate health effects include irritation of the eyes, nose and throat, headaches, dizziness, and fatigue; whilst longer terms effects can include respiratory diseases, heart disease and cancer. Under a duty of care, supported by country specific regulations and codes of practice, all Duty Holders (as an employer or someone in control of premises) are required to provide a safe workplace and manage the risk to health.

Regular indoor air quality monitoring provides validation to the employer that the maintenance program implemented to manage the risk of poor indoor air quality is sufficient and is working effectively.
