Industrial Boiler Daily Operating Check Checklist [FREE PDF]

Industrial boilers are subject to strict federal and state regulations under ASME Boiler and Pressure Vessel Code, OSHA 29 CFR 1910.147, and NFPA 85, requiring daily operational checks to prevent catastrophic failures. Regular inspection of pressure vessels, safety valves, combustion controls, and water treatment systems is mandatory to maintain safe working pressures and protect personnel. Failure to conduct documented daily checks can result in OSHA citations, insurance liability, and equipmen

Industry: Industrial Maintenance
Frequency: Daily
Estimated Time: 30-45 minutes
Role: Maintenance Technician
Total Items: 36
Compliance: OSHA 29 CFR 1910.147 - Control of Hazardous Energy (LOTO), NFPA 85 - Boiler and Combustion Systems Hazards Code, ASME Boiler and Pressure Vessel Code Section I, OSHA 29 CFR 1910.212 - Machine Guarding, SMRP Best Practices 2.0 - Maintenance Management

Pre-Startup Safety & Lockout/Tagout Verification

Verify all LOTO procedures are in place and safety systems are functional before boiler startup.

Have all lockout/tagout procedures been reviewed and authorized personnel identified prior to startup?
Are all warning signs, barriers, and access restrictions properly posted around the boiler room?
Is the boiler room free of flammable materials, debris, and unauthorized personnel?
Are emergency shutdown procedures and contact numbers posted and accessible?
Has the inspector confirmed personal protective equipment (PPE) requirements for this inspection?

Pressure & Water Level Monitoring

Check all pressure gauges and water level indicators for safe operating ranges.

Is steam pressure within the rated maximum allowable working pressure (MAWP)?
What is the current steam pressure reading (PSI)?
Is the water level gauge glass clean, properly illuminated, and showing level within normal operating range?
Has the low-water cutoff device been tested and verified operational?
Are all pressure gauges calibrated, within their valid calibration date, and reading accurately?
Is the feedwater pump operating correctly with no abnormal noise or vibration?

Combustion & Burner System

Inspect burner operation, flame conditions, and combustion air systems for safe and efficient operation.

Is the burner flame stable, properly shaped, and free of unusual color or pulsation?
Is combustion air supply unobstructed and combustion air damper operating correctly?
Are fuel supply pressure and flow within the specified operating range?
Is the flue gas temperature within acceptable limits and not indicating fouled heat transfer surfaces?
Is there visible smoke or abnormal stack emissions that would indicate incomplete combustion?

Safety Valves & Safety Controls

Verify all safety relief valves, interlocks, and automatic controls are functional.

Are all safety relief valves free of visible leaks, corrosion, or damage and within their inspection date?
Is the high-pressure limit switch set correctly and verified to trip at the rated set point?
Are all automated controls, modulating valves, and actuators responding correctly to control signals?
Is the flame safeguard control system functional with no lockout or fault codes displayed?
Are blowdown valves, blow-off valves, and drain valves in good working order and free of leaks?

Water Treatment & Quality

Assess boiler water chemistry to prevent scaling, corrosion, and carryover.

Have boiler water chemistry parameters (pH, conductivity, hardness) been tested and recorded today?
What is the current boiler water pH reading?
Is the chemical treatment dosing system operating and chemical supply levels adequate?
Has the continuous blowdown rate been adjusted based on current conductivity readings?
Is the deaerator or feedwater tank operating at the correct temperature and pressure?

Mechanical & Structural Inspection

Inspect physical condition of boiler casing, insulation, piping, and ancillary equipment.

Is the boiler casing, lagging, and refractory free of cracks, hot spots, or visible damage?
Are all steam and feedwater piping connections free of leaks, including valve packing and flanges?
Are all rotating components (fans, pumps, blowers) properly guarded per machine guarding requirements?
Is vibration on main pumps, fans, and motors within acceptable levels (no excessive vibration or bearing noise)?
Are expansion joints, flexible connections, and pipe supports in good condition and properly aligned?

Documentation & Shift Closeout

Complete all required logs, document deficiencies, and communicate findings to the next shift.

Have all operating parameters, test results, and readings been recorded in the boiler log?
Have any deficiencies, abnormal conditions, or near-misses been documented and reported to the Maintenance Manager?
Please describe any abnormal conditions, deficiencies, or corrective actions taken during this inspection.
Has a formal shift handover been completed with the incoming operator?
Are all open work orders and maintenance requests for this boiler current and up to date?
