Intent 1:
To supersede the requirement in Sentence 3.2.8.2.(1), which would otherwise require that dangerous goods
classified as flammable, lighter-than-air gases be stored in a dedicated
room, and allow their storage in the open, if the aggregate capacity
of expanded gas per fire compartment outside of the room is limited.
This is to limit the probability that:
- [limitation on aggregate capacity] 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, and
- [sprinkler and noncombustible construction requirements]
a fire in the building will spread and involve the gas cylinders,
which could lead to the further spread of fire or an explosion, which
could lead to harm to persons.
