Intent

Intent 1:

To limit the probability that occupants will:

  • be unable to control the principal ventilation fan when supplemental exhaust is required in bathrooms and kitchens, or
  • have difficulty finding the principal ventilation fan control or understanding the control's function.

This is to limit the probability of occupants being unaware of their ability to control ventilation fans, which could lead to fans not being used.

This is to limit the probability of the inadequate control of:

  • airborne pollutants,
  • oxygen and other components necessary for breathable air, or
  • relative humidity, which could lead to condensation, which could lead to the generation of pollutants from biological growth or from materials that become unstable on wetting.

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