Cooling Tower Inspection Checklist [FREE PDF]

Cooling tower inspections are critical for power generation facilities to comply with OSHA 29 CFR 1910.269 general industry standards, NERC CIP operational requirements, and local health department Legionella prevention mandates under ASHRAE 188. Improperly maintained cooling towers pose significant public health risks through Legionella pneumophila proliferation and can compromise grid reliability when mechanical failures cause unplanned generation outages. A comprehensive inspection program en

Industry: Power Generation
Frequency: Monthly
Estimated Time: 60-90 minutes
Role: Power Plant Operator
Total Items: 37
Compliance: OSHA 29 CFR 1910.269 - Electric Power Generation Transmission Distribution, NERC CIP-014-2 - Physical Security of BES Facilities, ASHRAE 188-2018 - Legionellosis Risk Management for Building Water Systems, NFPA 70E-2021 - Standard for Electrical Safety in the Workplace, EPA SDWA Section 1412 - National Primary Drinking Water Regulations

Water Quality & Chemical Treatment

Verify water chemistry parameters and chemical treatment systems are within acceptable operating ranges.

Is the basin water pH within the acceptable operating range of 6.5-8.5?
What is the current basin water pH reading?
Is the free chlorine or biocide residual within the required treatment range?
Are chemical dosing pumps and feed systems operating correctly?
Has a water sample been collected for laboratory Legionella testing this period?
Is conductivity (cycles of concentration) within the target operating range?

Basin, Fill Media & Distribution

Inspect the cold water basin, fill packing, and water distribution system for fouling and mechanical integrity.

Is the cold water basin free from significant sediment, biofilm, or organic debris accumulation?
Is fill media (packing) free from clogging, scaling, or biological fouling?
Is water distribution evenly distributed across all fill sections without dry spots?
Are spray nozzles or distribution headers free from blockages or damage?
Is the basin makeup water float valve and blowdown system functioning correctly?

Mechanical Equipment Inspection

Assess fans, motors, drive systems, and mechanical components for condition and operational integrity.

Are cooling tower fans operating smoothly without unusual vibration or noise?
Are fan blades free from cracks, erosion, or damage?
Are drive belts or gear boxes free from wear, slippage, or excessive oil leakage?
Are motor bearing temperatures within acceptable limits?
Are all mechanical guards and safety covers on rotating equipment securely in place?
Have lubrication intervals for bearings and mechanical components been completed on schedule?

Electrical Systems & Controls

Inspect electrical panels, motor control circuits, and instrumentation for safe and reliable operation.

Are motor control centers (MCCs) and electrical panels free from signs of overheating or arcing?
Are lockout/tagout (LOTO) procedures and equipment available and accessible for this unit?
Are all electrical connections and terminals free from corrosion or looseness?
Are process instrumentation sensors (temperature, flow, level) calibrated and reading accurately?
Is the variable frequency drive (VFD) for fan motors operating within normal parameters?

Drift Eliminators & Tower Structure

Evaluate drift eliminators effectiveness and overall structural condition of the cooling tower.

Are drift eliminators in place, undamaged, and free from visible scaling or fouling?
Is the tower structural frame free from corrosion, cracking, or deterioration?
Are access ladders, platforms, and walkways in safe condition with intact handrails?
Is the tower casing and louver section free from cracks, holes, or missing panels?
Is the plume visible drift appearing minimal with no significant mist carryover beyond the tower?

Legionella & Water Management Program

Confirm adherence to the site Water Management Plan (WMP) for Legionella risk control.

Is a current Water Management Plan (WMP) for Legionella documented and available on-site?
Have all WMP monitoring tasks been completed and logged for this inspection period?
Has the cooling tower undergone a full disinfection treatment within the last 12 months?
Are personnel responsible for the WMP trained and certified in Legionella risk management?
Are corrective action procedures defined for Legionella test results exceeding action limits?

Safety & Emergency Readiness

Assess site safety equipment, emergency response preparedness, and personnel protective equipment availability.

Is required personal protective equipment (PPE) available for chemical handling and tower entry?
Are safety data sheets (SDS) for all treatment chemicals readily accessible at the site?
Are emergency eyewash and safety shower stations functional and within 10 seconds of chemical handling areas?
Are all observation notes, corrective actions, and this inspection documented for regulatory records?
Are photos of current tower condition and any deficiencies attached to this report?
