| 9.6.5.4. | "(1) Hydrants shall be located within 90 m of the building face on which the principal entrance is located.
(2) A hydrant located within 45 m of a fire department connection, as required by Sentence 9.6.5.3.(1), shall be deemed to be in compliance with Sentence (1)."

|
Intent: |
The intention of this Article is to provide a water supply for the fire department to support fire suppression and rescue operations. Specifying hydrant location is one means of achieving this goal. Where a hydrant is located within 45 m of a required fire department connection, then the interior hose connections can be used. In this case, the initial requirement to have a hydrant within 90 m of the building face where the principal entrance is located is deemed unnecessary.

| Q1: | If a hydrant is within 90 m of the building face on which the principal entrance is located, can the fire department connection be located further than 45 m from a hydrant? | |
| A1: | In Article 9.6.5.4., a fire hydrant is required to be located within 90 m of the building face on which the principal entrance is located. In Sentence 9.6.5.4.(2)., an exception to this requirement is permitted where the building also has its standpipe fire department connection located within 45 m of a hydrant. This Article, however, does not waive the 45 m distance to the fire department connection required in Sentence 9.6.5.3(1) as suggested in the question. The only exceptions for the distance requirement to a fire department connection are identified in Sentences 9.6.5.3.(2) "where a booster pump equipped with emergency power is provided", and 9.6.5.3.(3) "where existing fire department connections are visible and accessible and are approved". |
|
| Q2: | Must a hydrant be located within 90 m of the building face on which the principal entrance is located when the building is provided with a fire booster pump equipped with emergency power? | |
| A2: | The Fire Code requires a hydrant within 90 m of the building face on which the principal entrance is located or within 45 m of a fire department connection which serves the standpipe system.
Although the primary objective of this Article is to ensure a water supply for the fire department's interior hose lines, the fire department must also be able to fight an exterior fire. If the Chief Fire Official is satisfied that an in-house fire booster pump can supply an adequate flow and pressure, is provided with a reliable power supply and it is possible to fight exterior fires using interior hose connections, then discretion could be exercised under Article 9.1.2.4. to accept a hydrant that was located more than 90 m from the building face on which the principal entrance is located. Complete elimination of the hydrant is not desirable because, if the pump should fail, there would be no other method of supplying water to the inside hoses. If a hydrant is available, even if there is no fire department connection it would still be possible to pump into the standpipe system by connecting to a 65mm hose connection in a ground floor hose cabinet using a suitable adapter. |
