Intent

Intent 1:

To limit the probability of an inability to clear blocked or damaged screens, which could lead to:

  • a reduction in exhaust air volume, which could lead to inadequate ventilation, which could lead to the inadequate control of:
    • relative humidity, which could lead to condensation, which could lead to the growth of mould and mildew, or
    • airborne pollutants, or
  • for outdoor air intakes, the depressurization of occupied space from which air is being exhausted, which could lead to the entry of combustion products from fuel-fired appliances into the building.

This is to limit the probability of negative effects on the air quality of indoor spaces, which could lead to harm to persons.
