Cooling Tower Quarterly Inspection

Quarterly inspection template for cooling towers covering fill condition, drift eliminators, legionella control program, basin condition, and related operational safety checks.

Inspection Setup and Safety Controls

• Inspection date, tower ID, and location recorded
• Lockout-tagout applied when required for internal access or exposed moving parts
  Verify OSHA 1910.147 lockout-tagout procedures are followed where inspection conditions require de-energized equipment or restricted access.
• Access points, ladders, and platforms are safe and unobstructed
• Required PPE is worn
  Select all PPE used for this inspection.

Fill, Drift Eliminators, and Internal Condition

• Fill is intact, evenly distributed, and free of excessive scale or biological growth
• Fill shows no collapsed sections, warping, or loose media
• Drift eliminators are installed correctly and free of damage, gaps, or bypass paths
• Air inlet and internal surfaces are free of debris, sludge, and visible corrosion

Basin and Water Quality Condition

• Basin is clean and free of sediment, sludge, scale, and standing debris
• Water level is within the normal operating range
• Makeup water, bleed-off, and overflow components are functioning as intended
• Basin strainers, screens, and sump areas are intact and unobstructed

Legionella Control Program

• Legionella control program is documented and current
  Confirm the facility has a written program with defined responsibilities, monitoring, corrective actions, and review intervals.
• Water treatment logs show required biocide, inhibitor, or disinfectant checks completed
• Recent microbiological or Legionella monitoring results reviewed
• Corrective actions from prior water quality excursions were completed and documented

Operational Safety and Mechanical Condition

• Fans, belts, motors, and guards show no abnormal vibration, noise, or visible damage
• Electrical enclosures and controls are closed, intact, and free of moisture intrusion
• Leaks, unusual odors, or unsafe conditions observed
