Intent 1:

To limit the probability that grease and embedded dust will accumulate in ducts, which could lead to:

• the blockage of ducts and outlets, which could lead to an inadequate exhaust capacity, or
• the generation of pollutants from biological growth.

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