89.3 INSPECTION MADE.
1. It shall be the duty of the commissioner, to inspect or cause
to be inspected internally and externally, at least once every twelve
months, except as otherwise provided in this section, in order to
determine whether all such equipment is in a safe and satisfactory
condition, and properly constructed and maintained for the purpose
for which it is used, all boilers and unfired steam pressure vessels
operating in excess of fifteen pounds per square inch, all low
pressure heating boilers and unfired steam pressure vessels located
in places of public assembly and other appurtenances used in this
state for generating or transmitting steam for power, or for using
steam under pressure for heating or steaming purposes.
2. The commissioner may enter any building or structure, public
or private, for the purpose of inspecting any equipment covered by
this chapter or gathering information with reference thereto.
3. The commissioner may inspect boilers and tanks and other
equipment stamped with the American society of mechanical engineers
code symbol for other than steam pressure, manufactured in Iowa, when
requested by the manufacturer.
4. a. An object that meets all of the following criteria
shall be inspected at least once every two years internally and
externally while not under pressure, and at least once every two
years externally while under pressure, unless the commissioner
determines that an earlier inspection is warranted.
(1) The object is a boiler with one hundred thousand pounds per
hour or more capacity, or the object is an unfired steam pressure
vessel or a regulated appurtenance that is part of the same system as
a boiler with one hundred thousand pounds per hour or more capacity.
(2) The object contains only water subject to internal continuous
water treatment under the direct supervision of a graduate engineer
or chemist, or one having equivalent experience in the treatment of
boiler water.
(3) The water treatment is for the purpose of controlling and
limiting serious corrosion and other deteriorating factors.
b. The owner or user of an object meeting the criteria in
paragraph "a" shall do the following:
(1) At any time the commissioner, a special inspector, or the
supervisor of water treatment deems a hydrostatic test is necessary
to determine the safety of an object, conduct the test under the
supervision of the commissioner.
(2) Keep available for examination by the commissioner accurate
records showing the date and actual time the object is out of service
and the reason it is out of service.
(3) Keep available for examination by the commissioner chemical
physical laboratory analyses of samples of the object water taken at
regular intervals of not more than forty-eight hours of operation as
will adequately show the condition of the water and any elements or
characteristics of the water which are capable of producing corrosion
or other deterioration of the object or its parts.
5. a. An object that meets the following criteria shall be
inspected at least once each year externally while under pressure and
at least once every four years internally while not under pressure,
unless the commissioner determines an earlier inspection is
warranted.
(1) The object is a boiler with one hundred thousand pounds per
hour or more capacity, or the object is an unfired steam pressure
vessel or a regulated appurtenance that is part of the same system as
a boiler with one hundred thousand pounds per hour or more capacity.
(2) The object contains only water subject to internal continuous
water treatment under the direct supervision of a graduate engineer
or chemist, or one having equivalent experience in the treatment of
boiler water.
(3) The water treatment is for the purpose of controlling and
limiting serious corrosion and other deteriorating factors.
(4) The owner or user is a participant in good standing in the
Iowa occupational safety and health voluntary protection program and
has achieved star status within the program, which is administered by
the division of labor in the department of workforce development.
b. The owner or user of an object that meets the criteria in
paragraph "a" shall do the following:
(1) At any time the commissioner, a special inspector, or the
supervisor of the water treatment deems a hydrostatic test necessary
to determine the safety of an object, conduct the test under the
supervision of the commissioner.
(2) Keep available for examination by the commissioner accurate
records showing the date and actual time the object is out of service
and the reason it is out of service.
(3) Arrange for an internal inspection of the object during each
planned outage by a special inspector or the commissioner.
(4) Keep for examination by the commissioner accurate records
showing the chemical physical laboratory analyses of samples of the
object's water taken at regular intervals of not more than
forty-eight hours of operation adequate to show the condition of the
water and any elements or characteristics of the water that are
capable of producing corrosion or other deterioration of the object
or its parts.
6. Internal inspections of cast aluminum steam, cast aluminum hot
water heating, sectional cast iron steam, and cast iron hot water
heating boilers shall be conducted only as deemed necessary by the
commissioner. External operating inspections shall be conducted
annually.
7. Internal inspections of steel hot water boilers shall be
conducted once every six years. External operating inspections shall
be conducted annually.
8. Internal inspections of unfired steam pressure vessels
operating in excess of fifteen pounds per square inch shall be
conducted once every two years. External inspections shall be
conducted annually. An internal inspection of an unfired steam
pressure vessel may be required at any time by the commissioner upon
the observation by an inspector of conditions, enumerated by the
commissioner through rules, warranting an internal inspection.
9. All power boilers that are converted to low pressure boilers
shall have a fifteen pound safety valve installed and be approved by
the commissioner no later than thirty days after the expiration date
of the certificate for the boiler.
10. An exhibition boiler does not require an annual inspection
certificate but special inspections may be requested by the owner or
an event's management to be performed by the commissioner. Upon the
completion of an exhibition boiler inspection a written condition
report shall be prepared by the commissioner regarding the condition
of the exhibition boiler's boiler or pressure vessel. This report
will be issued to the owner and the management of all events at which
the exhibition boiler is to be operated. The event's management is
responsible for the decision on whether the exhibition boiler should
be operated and shall inform the division of labor of the event's
management's decision. The event's management is responsible for any
injuries which result from the operation of any exhibition boiler
approved for use at the event by the event's management. A repair
symbol, known as the "R" stamp, is not required for repairs made to
exhibition boilers pursuant to the rules regarding inspections and
repair of exhibition boilers as adopted by the commissioner, pursuant
to chapter 17A.
11. An inspection report created pursuant to this chapter that
requires modification, alteration, or change shall be in writing and
shall cite the state law or rule or the ASME code section allegedly
violated. Section History: Early Form
