To limit the spread of hazardous substances beyond their point of release.

Objective:

OS3.4

APPLICATION:

Minimum mechanical ventilation rates for enclosed storage garages, where motor vehicles are parked by mechanical means, serving buildings described in Sentence 1.3.3.2.(1) of Division A.

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 the ventilation of storage garages for more than 4 motor vehicles in residential occupancies, as stated in Sentence 9.32.1.1.(3).

INTENT:

To modify the application of Sentences 6.2.2.3.(1) and 6.2.2.3.(2) so as to permit a reduction in ventilation requirements where the rate of carbon monoxide generation is lowered due to the movement of vehicles.

This is to limit the probability of inadequate ventilation, which could lead to an excessive accumulation of carbon monoxide gas in storage garages, which could lead to harm to persons.
