17. Fire-resistance rating:

(1)  Where a building is divided by a firewall with a fire-resistance rating of at least 2 hours, each part of the building shall be considered as a separate building.

(2)  No structural element required to have a fire resistance rating shall be supported by any other structural element which has a fire resistance rating lower than that required for the supported elements.

(3)  Any opening made in a required fire separation must be protected by a closing that conforms to Table 2 of Schedule B.

(4)  The public corridors of a building shall be separated from the rest of the building by a fire separation having a fire-resistance rating of at least 3/4 of an hour.

However, no fire-resistance rating is required where the floor area is protected by sprinklers and where it does not serve a sleeping accommodation.

This subsection does not apply here the unobstructed width of the corridor is greater than 4.5 m and where the floor area is protected by sprinklers and does not serve a sleeping accommodation.

A building that conforms to the safety requirements of Schedule F is deemed to conform to this subsection.

(4.1)  Every public corridor in a family-type hotel shall be separated from the rest of the floor area by a fire separation.

(5)  (Paragraph revoked).

(6)  In a public building, unless provided with a sprinkler system, any usable space under tiers of seats shall be separated from the seats by a fire separation with a fire-resistance rating of at least 3/4 of an hour.

(7)  (Paragraph revoked).
