Intent 1:
To supersede the requirements of Sentence 4.8.9.2.(1) and permit the installation of cargo pumps on piers
or wharves of combustible construction if certain measures are taken
[pumps are located in pump houses conforming to Subsection 4.8.10., and located not less than 3 m from other buildings].
This is to limit the
probability that:
- liquid spillage or leakage will not be contained, which
could lead to the spread of liquid outside of the pump house, which
could lead to the ignition of vapour from a nearby ignition source,
which could lead to harm to persons,
- a fire involving the pump and immediate area will spread
to involve the pump house, which could lead to the spread of fire
to other parts of the pier or wharf, which could lead to harm to persons,
- a fire involving the pump house will spread to adjacent
buildings or structures, which could lead to harm to persons in the
adjacent building or facility,
- leakage or spillage from the pump operations will spread
liquid to an adjacent property, which could lead to the ignition of
vapour from a nearby ignition source, which could lead to harm to
persons in the adjacent building or facility, and
- an ignition source in an adjacent property will ignite
vapour from the pump, which could lead to harm to persons in the building.
