Servicing Cooling Towers & Blower Fans Risk Assessment

1. Preparation:
   • Review the manufacturer’s instructions and safety guidelines for servicing the cooling tower and blower fan
   • Gather the necessary tools and equipment, including personal protective equipment (PPE) such as hard hat, safety glasses, gloves, and hearing protection
   • Turn off the power supply to the cooling tower and blower fan to ensure safety during servicing
2. Inspection:
   • Visually inspect the cooling tower and blower fan for signs of damage or wear
   • Check the electrical and mechanical components, including the motors, pumps, fans, and belts, for proper operation and wear
   • Inspect the cooling tower fill, distribution system, and basin for leaks or clogs
   • Check the water chemistry and treat as necessary to maintain the correct balance
3. Cleaning:
   • Clean the interior and exterior of the cooling tower and blower fan, removing any debris or buildup of organic matter
   • Clean and disinfect the fill, distribution system, and basin to prevent the growth of harmful bacteria
4. Maintenance and Repairs:
   • Replace any worn or damaged parts, such as belts, pumps, and motors
   • Adjust the fan speed and belt tension as necessary to ensure proper operation
   • Repair any leaks or clogs in the fill, distribution system, and basin
   • Test the operation of the cooling tower and blower fan after repairs are complete
5. Reassembly and Testing:
   • Reassemble the cooling tower and blower fan, following the manufacturer’s instructions
   • Turn the power supply back on and test the system for proper operation
   • Check the water chemistry again and treat as necessary
   • Document any maintenance or repairs performed during the servicing
6. Final Check:
   • Conduct a final inspection of the cooling tower and blower fan to ensure everything is in good working order
   • Check for leaks or signs of wear or damage
   • Ensure that the power supply is turned off before leaving the site.

1. Preparation:
   • Electrocution or electrical shock from not turning off the power supply before servicing
   • Trip or fall hazards from cluttered work areas or uneven surfaces
2. Inspection:
   • Electrocution or electrical shock from contacting live electrical components
   • Slips, trips, and falls from working at heights or in wet areas
   • Inhalation of harmful chemicals or vapors from the cooling tower water or cleaning agents
3. Cleaning:
   • Inhalation of harmful chemicals or vapors from the cooling tower water or cleaning agents
   • Contact with harmful bacteria or other microorganisms present in the cooling tower water
   • Slips, trips, and falls from working in wet areas
4. Maintenance and Repairs:
   • Electrocution or electrical shock from contacting live electrical components
   • Burns or cuts from working with sharp or hot components
   • Strain or injury from heavy lifting or awkward positioning
5. Reassembly and Testing:
   • Electrocution or electrical shock from contacting live electrical components
   • Burns or cuts from working with sharp or hot components
   • Strain or injury from heavy lifting or awkward positioning
6. Final Check:
   • Electrocution or electrical shock from failing to turn off the power supply before leaving the site

1. Electrocution or electrical shock:
   • Turn off the power supply before servicing
   • Use electrical test equipment to verify that electrical components are de-energized before servicing
   • Use grounded tools and equipment
   • Wear rubber gloves and other insulating personal protective equipment (PPE) as necessary
2. Trip or fall hazards:
   • Keep work areas clean and free of clutter
   • Use caution when working on uneven surfaces, such as ladders or scaffolding
   • Wear slip-resistant shoes with good traction
   • Use guardrails or safety harnesses when working at heights
3. Inhalation of harmful chemicals or vapors:
   • Use appropriate respiratory protection, such as a half-face respirator or full-face respirator, when working with chemicals or vapors
   • Avoid breathing in any mist or spray from the cooling tower water or cleaning agents
   • Ventilate the area as necessary to reduce exposure to harmful substances
4. Contact with harmful bacteria or other microorganisms:
   • Use appropriate personal protective equipment (PPE), such as gloves and eye protection, when handling the cooling tower water
   • Wash hands thoroughly after handling the cooling tower water or cleaning agents
   • Disinfect the work area after servicing
5. Burns or cuts:
   • Wear gloves and other appropriate PPE, such as eye protection and long sleeves, to protect against cuts and burns
   • Use caution when working with sharp or hot components
   • Use proper lifting techniques and equipment to avoid strain or injury
6. Strain or injury from heavy lifting:
   • Use proper lifting techniques and equipment to avoid strain or injury
   • Get help when lifting heavy components or equipment
   • Use a hoist or crane when necessary
