• A residence being locked up all day resulting in poor fresh air ventilation

• Location of walls and furniture that impair air movement

• Overcrowding of work spaces within business offices

What are the hazards?

• Elevated levels of carbon dioxide and low levels of oxygen due to low ventilation rate.

• Build up of chemical and biological contaminants that cause poor indoor air quality.

• Extremes in temperature causing fatigue, discomfort and distraction.

• High humidity contributing to bacterial and mould growth.

• Excessive and irritating odors causing discomfort.

• Accumulation of dust and dirt caused by poor ventilation.
