Finally, the inspector will review the boiler log and the records of maintenance and
feedwater treatment to determine what regular tests have been made on the boiler and
controls. He will consult the owner or user regarding any repairs made since the last
inspection and will review such repairs for compliance with Chapter III of the National
Board Inspection Code.
The inspector will discuss any defects or deficiencies in the condition or the operating
and maintenance practices of the boiler and auxiliary equipment with the owner or user
at this time and recommend any necessary corrective actions.
A National Board commissioned inspector is a well-trained, experienced individual, who
may be in the employ of your insurance carrier, a state of the U.S. or a province or
Canada, or a large municipality. He offers you an independent evaluation of your
boiler's physical condition. He will recommend only repairs or maintenance necessary
to safeguard the integrity of your boiler. His prime interest is public safety. Listen to
him and follow his advice.
