What causes Sick Building Syndrome (SBS)?

Sick Building Syndrome arises from contaminated indoor air, where poor ventilation and pollutants cause headache, fatigue and irritation.

Corrosion or erosion (A) is structural decay of the building, not a cause of occupant symptoms.

Contaminated water supply (C) leads to waterborne disease, not the air-linked syndrome.

A landslide prone location (D) is a site hazard, unrelated to indoor air quality.

SBS symptoms ease after leaving the building and return on re-entry.

Volatile organic compounds, moulds and inadequate fresh-air exchange are common indoor triggers.
