Regulations, Licensing, and Operator Responsibilities
Regulation items ask who has authority and what the operator must document.
The framework
ASME Boiler and Pressure Vessel Code sets construction rules (Section I power, Section IV heating, Section VIII vessels) and ASME CSD-1 covers controls for heating boilers. The NBIC governs in-service inspection, repair and alteration; repairs generally require a holder of the appropriate NBIC stamp and jurisdiction notification. Each state, province or local jurisdiction enforces its own boiler law: registration, certificate of inspection, operating certificates, required operator licensing by class (steam vs hot water, high vs low pressure), and inspection intervals, commonly annual.
Operator responsibilities
The licensed operator in charge is legally accountable for the safe operation of the plant. That includes maintaining water level and treatment, performing and recording blowdowns and tests, keeping the log accurate and contemporaneous, confirming safety devices are in service, reporting accidents and defects immediately, not permitting unauthorized persons to operate equipment, and not operating a boiler that is out of inspection or has an expired certificate.
Records and reporting
Logs of pressure and temperature, water tests, blowdowns, safety valve tests and repairs are official records. Accidents, failures and unsafe conditions must be reported to the authority having jurisdiction within the required time, and the scene should be preserved for investigation.
Traps
Manufacturer recommendations and company policy never override the jurisdiction's rule. A common distractor has the operator postponing a required inspection because production is high, or making a weld repair in-house without the required stamp and notification.
Worked rule
When jurisdiction rule and company practice conflict, follow the stricter requirement, document it, and notify the authority having jurisdiction in writing.
