Section 12-222.1-10 - Attendance(a) An unattended power boiler log (Exhibit 4) shall be maintained by owners or operators at the boiler operating area to record daily checks and inspections and the following shall apply: (1) Boiler operation log entries shall be updated; daily, not to exceed twelve (12) hours for a single entry; and(2) The daily operating log shall be available to the inspector of record for a period of not less than six (6) months.(b) Power boilers, waste heat boilers, and high-temperature water boilers subject to this chapter shall not be left in operation unattended by a competent attendant for a period of time longer than it will take the water level to drop from a normal operating level to the lowest permissible water level, as indicated by the water gage glass, or by indicating devices or recorders, when the feed water is shut off and the boiler is forced to its maximum capacity, unless all of the following are complied with where applicable: (1) The boiler is equipped with a strobe or flashing light that will operate when the water reaches the lowest permissible operating level, or, for boilers having no fixed steam or water line, when the highest permissible operating temperature is reached. The strobe or flashing light shall be so located that can be plainly seen at the most remote point from the boiler at which the attendant is required to work. Audible alarms, when used, shall be distinctly audible above the ambient noise level; (2) The boiler is equipped with two low water safety devices with separate water connections to the boiler that will shut off the fuel to the burner or burners when the water reaches the lowest permissible operating level, or, for boilers having no fixed steam or water line, when the highest permissible operating temperature is reached. These devices shall require manual resetting unless the burner is equipped with a full safety pilot control;(3) A competent attendant personally checks the operation of the boiler, the necessary auxiliaries, and the water level of the boiler at such intervals, not exceeding sixty (60) minutes, as necessary to insure the safe operation of the boiler. The operation of the automatic water level controls shall be tested such that fuel to the burner will be shut off at the beginning of each daily period of operation and at intervals not to exceed twelve (12) operating hours. A record of each inspection and check of controls shall be maintained and available to an inspector for a period of six (6) months prior to the inspection;(4) There is a conspicuous and readily accessible safety disconnect switch located adjacent to the boiler room entrance or, in the situation where the boiler is located outside, in the immediate vicinity of the boiler which, when operated, will cut off all power to the boiler and cause it to shut down in a safe manner. Immediately adjacent to the disconnect device there shall be posted a sign conspicuously directing the observer to use the device for shutting down the boiler in event of emergency, such as observing any unsafe condition or functioning of the boiler or its appurtenances or any condition or function of the boiler which is unusual, or which is, in the observer's opinion, potentially hazardous;(5) A competent attendant means a person who is familiar with the operation of the boiler and may be certified by a curriculum accredited college, university, technical school, or organization serving the boiler industry;(6) The minimum standards to be met for an attendant to be competent include, but are not limited to the following, as detailed in the ASME BPVC Section VII: (A) The ability to explain the function and operation of all controls and safety devices on the boiler and operate the boiler in a safe manner;(B) The knowledge of all possible methods of feeding water to the boiler; and boiler blowoff/blowdown procedure; and(C) Shutting down the boiler or boilers in a safe manner; and(7) The attendant performs a recommended operation checklist schedule recorded at each regular shift not to exceed twelve (12) hours, and checks and records the following: (A) Externally examine unit for leaks or unusual conditions;(C) Check gages, monitors, and indicators;(D) Low water cutoff and alarm test; and(E) Water column and gage glass blowdown.
