3.2.8.2.(2)

Attribution
(a) [F01-OS1.1]
Application
Application 1: 
Storage of cylinders of Class 2.1 flammable, lighter-than-air gases outside of rooms described in Sentence 3.2.8.2.(1), in unsprinklered buildings of combustible construction, where the aggregate capacity of expanded gas in a single fire compartment outside of the room is not more than 60 m3.
This applies to buildings or parts of buildings used for the short- or long-term storage of cylinders of Class 2.1 flammable gases when stored in single fire compartments in quantities greater than those shown in Table 3.2.7.1., whether raw or waste materials, goods in process, or finished goods.
Exceptions: 
except as stated in:
  • Sentence 3.1.1.4.(1), which applies to:
    • the storage and dispensing of Class 2.1 flammable gases at fuel-dispensing stations, and
    • facilities operated by manufacturers or distributors [handling or storing more than 1 500 kg, as stated in Appendix Note A-3.1.1.4.(1)(a)] of Class 2 gases, and
  • Subsection 3.2.5., which applies to the indoor storage of aerosol products.

Intent
Intent 1: 
To supersede the requirement in Sentence 3.2.8.2.(1), which would otherwise require that Class 2.1 flammable, lighter-than-air gases be stored in a dedicated room, and allow their storage in the open in unsprinklered buildings of combustible construction, if the aggregate capacity of expanded gas per fire compartment outside of the room is limited.
This is to limit the probability that gases will accumulate in sufficient quantity to form an ignitable mixture at floor level or in low areas, which could lead to the ignition of the gases from a nearby ignition source, which could lead to harm to persons.
