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.
