Air Receivers and Relief Valves
As a result of this casualty and other similar incidents, the U. S.
Coast Guard strongly recommends that UTV Owner/Operators, vessel
engineers, Insurance surveyors and other inspectors ensure that:
? A data plate is attached to the receiver and pressure relief devices.
If missing or damaged the UTV representative should provide evidence to
prove the components were constructed to an approved standard. Otherwise
this equipment should be taken out of service or replaced.
? The data plates associated with the receiver and pressure relief
device remain unpainted and legible. Take care to minimize damage to the
plates if paint needs to be removed. Pressure relief devices should not
be painted as paint can interfere with the lifting of the valve. Those
that are painted should be lift tested to ensure proper operation.
? Safety relief valves are not capable of being isolated or their
operation prevented by being wired or secured in a position that
prevents the valve from opening.
RELIEF VALVES MUST NEVER BE SECURED IN THE CLOSED POSITION
? Each receiver is equipped with a drain valve to remove condensate and
all crewmembers making rounds in the machinery space are instructed to
drain the condensate as part of their regular machinery space duties,
? All repairs and alterations to air receivers and pressure relief
devices are conducted by companies holding the National Board of Boiler
and Pressure Vessel
