Unless the Department of Labor and Workforce Development establishes by regulation a different edition, the most current edition of the National Board Inspection Code Manual for Boiler and Pressure Vessel Inspectors constitutes the minimum boiler and pressure vessel inspection standard of the state for boilers and pressure vessels after they have received their initial inspection certificates from the Department of Labor and Workforce Development. The Department of Labor and Workforce Development may adopt regulations for the maximum practical implementation of the manual and may grant an exception from a specific provision of the manual when the department determines that the implementation of the provision would be impractical.
