40-B:C shall be provided in the vicinity of
Class I liquid pumps and fuel dispensers.
2) Portable extinguishers shall be kept in the pump house
or other suitable location where they will be accessible in the
event of an emergency, but not accessible to the
public.
3) Where marine vessels are loading or unloading flammable liquids or combustible liquids or are being refuelled, portable extinguishers with a rating of not less than
40-B:C shall be placed on the pier or wharf
in the vicinity of loading or unloading operations so that they
are accessible in the event of a fire emergency.
4) Portable extinguishers provided in conformance with
Sentence (3) shall be in addition to those provided on board the marine
vessels.
1) Operating personnel shall be trained on how to summon
the nearest fire department in the event of fire.
1) Except as permitted in Sentence (2), the bulk transfer of flammable liquids or combustible liquids shall be permitted only on piers and wharves used exclusively for that
purpose.
2) Where it is not practicable to locate bulk transfer
stations on separate piers and wharves, such stations are
permitted to be located on general purpose piers and wharves
provided that guards or fences are installed around valves or
pumping equipment to prevent entry of unauthorized
personnel.
1) Measures to accommodate possible leakage or spillage
from hose couplings shall be provided in conformance with
Subsection 4.1.6.
2) Provision shall be made to prevent spillage resulting
from the disconnection of hoses.
