If the documentation described in items A to C cannot be obtained, other forms of documentation in which the information can be verified and which are sufficient to determine the appropriate class and grade, may be submitted to the chief boiler inspector for consideration.

Subp. 10.

Year defined.

For purposes of this chapter, a "year" is at least 2,000 hours. However, in the case of low pressure heating boilers, a year is defined as a 12-month period which includes the heating season operating, and the remainder of the year maintaining, the low pressure boiler.

5225.1000 BOILER HORSEPOWER RATING.

In rating the horsepower of a boiler plant, inspectors shall use the horsepower of each boiler and compute the total horsepower of all boilers connected to the header, whether all the boilers are in use or not.

Where the heating surface cannot be discerned, the boiler horsepower shall be determined by calculating Btu boiler-rated input divided by 67,000.

For purposes of operating engineer license requirements, boiler horsepower for conventional boilers and steam coil type generators is determined as provided in Minnesota Statutes, section 326B.978, subdivision 17. For electrically operated boilers for this purpose, ten kilowatts equal one boiler horsepower.

5225.1110 BOILER OPERATION STANDARDS; ALL PLANTS.

Subpart 1.

Safe boiler operation.

All boilers, unless specifically exempted by Minnesota Statutes, section 326B.988, must be operated, maintained, and attended by an operating engineer in a prudent and attentive manner to avoid endangering human life and property. At a minimum, all operating boilers must be checked by an operating engineer in compliance with this chapter. Specific minimum attendance requirements for hobby boilers are given in part 5225.1140 and specific minimum attendance requirements for high pressure plants are given in part 5225.1180.

In determining whether a boiler is operated, maintained, and attended in a prudent and attentive manner, the division and the chief engineer or operating engineer shall consider the recommendations of the American Society of Mechanical Engineers Boiler and Pressure Vessel Code, Section VI, for low pressure and Section VII, for high pressure along with the following additional factors:

A.

the size or capacity of the boiler plant;

B.

the condition of boilers and appurtenances;

C.

the frequency of boiler checks and past maintenance history;

D.

the extent of public occupancy of the building containing the boiler plant;

E.

the operating service conditions, including weather;

F.

compliance with other statutes and rules of this division; and

G.

any other factor which would adversely affect the safety of the boiler.

A logbook must be maintained in the boiler room by the chief engineer or an operating engineer designated by the chief engineer. The log shall document when the boiler checks were made, who made the boiler checks, and what specific checks of equipment were made. This log shall be made available to the boiler inspector during inspections and at other times upon request of the boiler inspector.

Subp. 2.

Unsafe boiler plant.

If the chief engineer or operating engineer has found the boiler to be in an unsafe condition, the engineer shall notify the owner or employer and the chief boiler inspector as soon as possible. If the unsafe boiler is not immediately taken out of service, the chief engineer or operating engineer shall ensure that the boiler is continuously monitored by an operating engineer, 24 hours per day, until the division has either sealed the object, verified that the unsafe condition has been corrected, or determined that continuous monitoring is no longer required.

5225.1180 ATTENDANCE AT HIGH PRESSURE PLANT.

Subpart 1.

Attendance; plant of 0 to 30 horsepower.

At a minimum, a high pressure boiler plant of 0 to 30 horsepower, when in operation, must be checked daily by an operating engineer.

Subp. 2.

Attendance; plant of 31 to 200 horsepower.

A.

A high pressure boiler plant of 31 to 200 horsepower may be left in operation unattended by an operating engineer for no more than two consecutive hours when the premises are occupied by employees or the public, except as permitted by item B.

B.

A high pressure boiler plant of 31 to 200 horsepower is exempt from the high pressure attendance requirements of item A, but must be checked at least daily, under the following conditions:

(1)

the boiler is equipped with dual pressure controls and dual low water fuel cutouts and the boiler does not exceed 15 pounds per square inch operating pressure at any time during the operating engineer's absence;

(2)

the boiler is equipped with fail-safe type safety controls or valves regulating pressure, temperature, water level, and control supply lines. Fuel control and safety devices must meet at least the minimum requirements for automatically fired boilers in Sections I and IV of the American Society of Mechanical Engineers Boiler and Pressure Vessel Code;

(3)

the valves and controls must be manually switched over by the operating engineer, the dates and time must be entered in the boiler room log, and the entry must be signed by the operating engineer;

(4)

the building in which the boiler is located is not occupied by the public or employees except for custodial, maintenance, or security personnel; and

(5)

the boiler is for supplying steam directly to a low pressure header with header safety valves set at or below 15 pounds per square inch and is of adequate capacity to prevent a pressure rise above 15 pounds per square inch in the system. The shutoff valve between the high and low pressure systems must be electrically interlocked with the low pressure control system so that the crossover valve is in the open position while operating on low pressure.

Each source of feeding must be capable of supplying water to the boiler at a pressure of three percent higher than the highest setting of any safety valve on the boiler. For boilers that are fired with solid fuel not in suspension, and for boilers whose setting or heat source can continue to supply sufficient heat to cause damage to the boiler if the feed supply is interrupted, one such means of feeding must not be susceptible to the same interruption as the other, and each source must provide sufficient water to prevent damage to the boiler.

When electrically driven feed pumps are used and there is no other reliable independent source of electrical supply, there must be maintained ready for service steam-driven feed pumps or injectors (inspirators) of sufficient capacity to safeguard the boilers in case of failure of electric power.
