02-041 C.M.R. ch. 76, § 4 - Periodic Inspections of Pressure Vessels

1. Inspection Methods and Frequency

A. Pressure Vessels Generally. Before the initial inspection certificate expires, and every three (3) years thereafter, pressure vessels in the State must be inspected as follows:

(1) An Inspector must perform a certificate inspection of the pressure vessel;

and

(2) When construction permits, the triennial certificate inspection must be internal. In the event that an internal inspection is not feasible due to construction features, the Inspector must use an alternative method of determining material thickness of the shell and/or head.

B. Water Heaters Located in Schoolhouses. Before the initial inspection certificate expires, and every twelve (12) months thereafter, water heaters located in schoolhouses in the State must be inspected as follows:

(1) An Inspector must perform a certificate inspection of the water heater located in the schoolhouse; and

(2) The annual certificate inspection must be internal whenever construction permits. In the event that an internal inspection is not feasible due to construction features, the Inspector must use an alternative method of determining material thickness of the shell and/or head.

"Water heaters located in schoolhouses" mean fired storage water heaters located in schoolhouses that are not exempt pursuant to 32 M.R.S. §15102(2)(I).

2. Report. The Inspector must submit to the director a report of each inspection performed pursuant to Section 4, Subsection 1 of this Chapter on a form approved by the director.

3. Exception. Those companies that are participating in the TAPPI Paper Machine Dryer Can Inspection Program may request permission to be issued an inspection certificate from the director upon verification by the Inspector that the company is adhering to the TAPPI standards.
