To limit the spread of hazardous substances beyond their point of release.
Objective:
OH1.1
APPLICATION:
Control of air contaminant spread within buildings described in Sentence
1.3.3.2.(1) of Division A, where heating, ventilating or
air-conditioning systems:
- serve spaces that contain sources of contamination, or
- serve other occupied parts of buildings but are located in or run through spaces that contain sources of contamination.
This also applies to buildings to which Part 9 applies [see Sentence
1.3.3.3.(1) of Division A for application
of Part 9], with respect to:
- mechanical ventilating systems other than self-contained systems serving single dwelling units, as stated in Sentence 9.32.1.2.(2),
- the ventilation of storage garages for more than 4 motor vehicles in residential occupancies, as stated in Sentence 9.32.1.1.(3), and

INTENT:
To limit the probability that the inappropriate design of
heating, ventilating or air-conditioning systems will lead to the spread of
contamination to other occupied parts of buildings, which could lead to negative
effects on the air quality of indoor spaces, which could lead to harm to persons.
