reliable or practicable due to noise. Where communication by VHF/UHF is

without formal permission.
10.11 Pumproom Operational Precautions
A pumproom contains the largest concentration of cargo pipelines of any
space within the ship and leakage of a volatile product from any part of this
ึ
system could lead to the rapid generation of a flammable or toxic atmosphere.
The pumproom may also contain a number of potential ignition sources
unless formal, structured maintenance, inspection and monitoring procedures
are strictly followed.
10.11.1 General Precautions
Before starting any cargo operation:
An inspection should be made to ensure that strainer covers,
inspection plates and drain plugs are in position and secure.
Drain valves in the pumproom cargo system, especially those on cargo
oil pumps, should be firmly closed.
Any bulkhead glands should be checked and adjusted or lubricated, as
necessary, to ensure an efficient gas-tight seal between the pumproom
and the machinery space.
During all cargo operations, including loading:
The pumproom should be inspected at regular intervals to check for
leakages from glands, drain plugs and drain valves, especially those
fitted to the cargo pumps.
If the pumps are in use, pump glands, bearings and the bulkhead
glands (if fitted) should be checked for overheating. In the event of
leakage or overheating, the pump should be stopped.
No attempt should be made to adjust the pump glands on rotating
shafts while the pump is in service.
