Indoor air quality means the physical, chemical, and biological characteristics of the air in a non-residential workplace (e.g., an office) where there are no work processes or operations that could affect the workers’ comfort.
Some of most common symptoms of poor indoor air quality are headaches, skin irritation and dizziness.
Many indoor air quality concerns can be prevented by ensuring ventilation is adequate, temperature and humidity levels are comfortable, and by minimizing airborne contaminants.
Employers who own late night retail premises are required to conduct workplace hazard assessments that comply with the approved safety standards for their industry. Once the hazards have been identified, the risks can be assessed and the appropriate controls or preventative measures can be put in place. A hazard assessment for late night retail premises must be reviewed and updated every three years. Updates must also be made whenever there is a change in circumstances.
