The Ontario Building Code | Combustible Refuse Storage
3.6.2.5. Combustible Refuse Storage
(1) Except as required by Sentence 3.6.3.3.(9), a room for the storage of combustible refuse shall be,
(a) separated from the remainder of the building by a fire separation with a fire-resistance rating not less than 1 h, and
(b) sprinklered.
In Plain Language
A room for storing combustible refuse must be separated from the rest of the building by a fire separation rated at least 1 hour and must be sprinklered, since accumulated refuse is a common and unpredictable fire source.
