Boiler periodic inspection and boiler room compliance checks are the two key steps for operating heating and process boilers safely. FKT NDT carries out periodic inspections of solid, liquid and gas fired boilers as well as compliance checks of boiler rooms, so that both the equipment and its surroundings are assessed against the relevant standards.
Boilers Covered
- Steam boilers and steam generators
- Hot water and superheated water boilers
- Solid, liquid and gas fired boilers
- Cooking kettles
- Water heaters and combi boilers
Boilers are pressure equipment, so you may also want to see our pressure vessels page.
Boiler Periodic Inspection and Legal Basis
Periodic inspection of boilers is an employer obligation under Türkiye’s Regulation on Health and Safety Conditions in the Use of Work Equipment (2013). The interval and criteria follow the manufacturer’s specifications where available; otherwise they are set by risk assessment, considering workplace conditions and the frequency and duration of use. Inspections refer to the standards matching the boiler’s design, for example TS EN 12952 for water-tube boilers and TS EN 12953 for shell boilers.
Boiler Room Compliance Checks
Boiler compliance checks should ideally be addressed before installation. In practice, they are usually performed after installation or while the natural gas connection is being made, as part of the conformity assessment.
The flue (chimney) is checked first. In addition, the following are assessed against the relevant standards, particularly from an occupational health and safety perspective:
- Warning and information signs
- Distances between boilers
- Distances between boilers and walls
- Suitability of flue connections
- Boiler electrical panels
Boiler room compliance checks do not have to be repeated periodically. FKT NDT provides third-party, independent, accredited inspection services for boiler room compliance checks.
What the Periodic Inspection Includes
- Document review: manufacturing documents, nameplate, operating pressure and temperature, maintenance records and previous reports.
- Visual inspection: shell, fire tubes and water tubes, welded joints, flanges and insulation checked for corrosion, deformation and leaks. See visual inspection.
- Safety device checks: safety valves, pressure gauges, pressure switches, thermostats, water level gauges and low-water safety controls.
- Hydrostatic test and NDT: a pressure test is applied under the conditions set by the regulation and the boiler’s standard. If the nature of the boiler makes a hydrostatic test impossible, the alternative methods defined in the standard can be used, for example wall thickness measurement by ultrasonic inspection and surface examination of welds. Being unable to shut the boiler down is not accepted as a reason on its own.
Report and Follow-up
The report records boiler identification, the tests and examinations performed, results, any deficiencies and an assessment of fitness for use. Deficiencies are stated clearly so your maintenance team and OHS specialist can act on them.
Frequently Asked Questions
Is boiler periodic inspection mandatory?
Yes. Boilers are pressure work equipment covered by the regulation, and arranging their periodic inspection is the employer’s responsibility.
Does a boiler room compliance check need to be repeated every year?
No. Boiler room compliance checks do not have to be repeated periodically. Periodic inspection of the boiler itself is a separate obligation.
When should a compliance check be done?
Ideally before installation. In practice it is usually done after installation or at the natural gas connection stage.
Can a boiler be inspected while it is running?
Functional checks of safety devices and some NDT can be done in operation, but a hydrostatic test requires taking the boiler out of service.
