8.1 Temperature controlled unit power outlets
should provide a safe, watertight electrical connection.
8.2 Temperature controlled unit power outlets
should feature a heavy duty, interlocked and circuit breaker protected
electrical power outlet. This should ensure the outlet can not be
switched "live" until a plug is fully engaged and the actuator rod
is pushed to the "On" position. Pulling the actuator rod to the "Off"
position should manually de-energize the circuit.
8.3 The temperature controlled unit power circuit
should de-energize automatically if the plug is accidentally withdrawn
while in the "On" position. Also, the interlock mechanism should break
the circuit while the pin and sleeve contacts are still engaged. This
provides total operator safety and protection against shock hazard
while eliminating arcing damage to the plug and receptacle.
8.4 Temperature controlled unit power outlets
should be designed to ensure that the worker is not standing directly
in front of the socket when switching takes place.
8.5 The positioning of the temperature controlled
unit feed outlets should not be such that the flexible cabling needs
to be laid out in such a way as to cause a tripping hazard.
8.6 Stevedores or ship's crew who are required
to handle temperature controlled unit cables and/or connect and disconnect
reefer units should be given training in recognizing defective wires
and plugs.
8.7 Means or provisions should be provided to
lay the temperature controlled unit cables in and protect them from
lashing equipment falling on them during lashing operations.
8.8 Defective or inoperative temperature controlled
unit plugs/electrical banks should be identified and confirmed as
"locked out/tagged out" by the vessel.
