  • • Failure to detect build‑up of airborne contaminants, fumes, sawdust or smoke in occupied areas
  • • Inadequate implementing of indoor air quality measures, such as CO2 monitoring in enclosed spaces
  • • Occupant discomfort, heat stress or respiratory irritation due to poor airflow and temperature control
  • • Lack of baseline and periodic IAQ monitoring, leading to undetected long‑term health risks
  • • Reliance on subjective complaints rather than objective IAQ measurements
6. Operation & Control of Mechanical Ventilation and Booster Systems
