Objective	OS1 Fire Safety
Attribution	[F02-OS1.2]
Application	Application 1: Maximum total [aggregate] capacity--in a single fire compartment--of cabinets used for the indoor storage of flammable liquids, combustible liquids and unstable liquids, where such liquids are stored in industrial occupancies: in quantities in excess of those permitted in the open as stated in Sentences 4.2.8.2.(1) and 5.5.5.1.(2), and in containers conforming to Clauses 4.2.3.1.(1)(a) to (d) that have a capacity of not more than 230 L, or portable tanks conforming to Clause 4.2.3.1.(1)(e) that have an individual capacity of not more than 2 500 L. Exceptions: except as exempted in: Sentences 4.1.1.1.(2) and (3), which apply to unique hazards at process plants, in transportation, for oil burning equipment, on farms and isolated construction projects, and the storage of aerosol products, Article 4.1.5.8., which applies to basement storage, and Sentence 4.2.1.1.(2), which applies to: fuel dispensing stations, bulk plants, refineries and distilleries, liquids in motor or engine fuel tanks, distilled beverage alcohol in closed containers when stored in conformance with Part 3, food and pharmaceutical products when in closed containers having a capacity of not more than 5 L, and products containing not more than 50% by volume of water-miscible flammable liquids or combustible liquids [with the remainder of the solution being non-flammable], when in closed containers having a capacity of not more than 5 L.

Intent	Intent 1: To waive the total capacity limits in Sentence 4.2.10.3.(1) if measures are taken to limit the probability that a fire involving the maximum quantities of liquids in cabinets [as stated in Sentence 4.2.10.3.(1)] will spread and involve liquids in the other [additional] cabinets within the same fire compartment. This is to limit the probability that a fire involving the stored liquids will spread to other parts of the building, which could lead to harm to persons.
