Industrial Boiler Daily Operating Check Checklist [FREE PDF]

Industrial boilers operate under extreme pressure and temperature conditions, making daily inspections critical for both safety and regulatory compliance. OSHA 29 CFR 1910.217 and ASME Boiler and Pressure Vessel Code Section I mandate routine operational checks to prevent catastrophic failures. This checklist ensures maintenance technicians systematically verify combustion, pressure, water treatment, and safety device integrity before and during each operating shift.

Industry: Industrial Maintenance
Frequency: Daily
Estimated Time: 30-45 minutes
Role: Maintenance Technician
Total Items: 35
Compliance: ASME Boiler and Pressure Vessel Code Section I, OSHA 29 CFR 1910.147 Control of Hazardous Energy (LOTO), NFPA 85 Boiler and Combustion Systems Hazards Code, NFPA 70E Standard for Electrical Safety in the Workplace, ISO 55000 Asset Management Systems

Pre-Startup & Lockout/Tagout Verification

Confirm all energy isolation and safety procedures are in place before initiating boiler startup.

Have all LOTO procedures been reviewed and documented prior to any maintenance access?
Is the boiler room clear of unauthorized personnel during startup sequence?
Are all manufacturer-specified pre-startup checks completed per the Operations & Maintenance manual?
Is the emergency shutdown procedure posted and accessible at the boiler control panel?
Have all previous shift deficiencies or work orders been reviewed before startup?

Water Level & Feedwater Controls

Verify water level indicators, low-water cutoffs, and feedwater system are functioning correctly.

Is the water level visible and within the safe operating range on the gauge glass?
Has the low-water cutoff (LWCO) been tested and verified to function correctly today?
Is the feedwater pump operating within normal pressure and flow parameters?
Are feedwater temperature and conductivity within specified limits?
Current boiler water level reading (inches from normal operating level)?

Combustion System & Burner Inspection

Inspect burner operation, fuel supply, and combustion air systems for safe and efficient operation.

Is burner flame appearance stable, without flickering or unusual color changes?
Are fuel supply pressure readings within the designed operating range?
Is combustion air damper fully operational and set to correct position?
Are flue gas readings within acceptable CO and O2 concentration limits?
Stack exhaust temperature (°F)?

Pressure Controls & Safety Devices

Verify all pressure relief valves, controls, and safety interlocks are in proper working condition.

Is operating steam or water pressure within the Maximum Allowable Working Pressure (MAWP)?
Are all pressure relief valves free from leaks, corrosion, or physical damage?
Is the high-pressure safety cutout control set and verified at the correct setpoint?
Current operating pressure reading (PSI)?
Are pressure gauge calibration dates current and within the required calibration interval?

Electrical & Control Panel Inspection

Inspect electrical panels, control circuits, and instrumentation for safe operating condition.

Is the control panel free from warning indicators, fault codes, or alarm conditions?
Are all electrical enclosures properly closed, latched, and free from moisture intrusion?
Are all control wiring connections secure with no evidence of overheating or burning?
Is the flame safeguard control operational and displaying normal status?
Are all instrumentation and sensor readings matching expected operational values?

Physical Integrity & Leak Inspection

Conduct visual inspection of boiler body, piping, insulation, and structural components.

Is the boiler exterior free from visible cracks, corrosion, or weld defects?
Are steam and water piping connections free from leaks or seeping joints?
Is insulation on steam piping and boiler body intact and free from damage?
Photograph of boiler exterior condition taken?
Are all access doors, manholes, and handhole covers properly sealed and secured?

Blowdown & Water Treatment

Verify daily blowdown procedures and water treatment chemical levels are within specification.

Has the daily bottom blowdown been performed per the established schedule?
Is boiler water pH within the acceptable range (typically 10.5–11.5 for steam boilers)?
Are chemical treatment dosing pumps operating and chemical supply levels adequate?
Is boiler water total dissolved solids (TDS) within the manufacturer-specified limit?
Additional observations or corrective actions taken during this inspection?
