Intent

Intent 1:

To limit the probability that vapours and pollutants produced by cooking will not be captured.

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

  • airborne pollutants and vapours, 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.

Intent 2:

To exempt cooking appliance exhaust fans serving cooktops in kitchens from the requirement to locate the fan intake on or near the ceiling, on the basis that the exhaust fan intakes capture cooking vapours and pollutants before they can disperse and rise towards the ceiling.
