Servicing Air Conditioners Risk Assessment

1. Preparation:
   • Turn off power: Before starting any service work, turn off the power to the AC system to prevent electrical shock.
   • Gather tools: Gather the necessary tools, such as screwdrivers, pliers, and a refrigerant gauge, to complete the service work.
   • Locate the AC unit: Identify the location of the AC unit and ensure that it is accessible for service.
2. Inspection:
   • Check refrigerant levels: Check the refrigerant levels using a refrigerant gauge to determine if the AC is low on refrigerant.
   • Inspect the condenser and evaporator coils: Check the condenser and evaporator coils for any signs of damage or dirt build-up, which can reduce the efficiency of the AC system.
   • Inspect the air filter: Check the air filter to ensure that it is clean and replace if necessary. A dirty air filter can reduce the efficiency of the AC system.
3. Cleaning:
   • Clean the condenser and evaporator coils: Use a soft brush to remove dirt and debris from the coils. A dirty coil can reduce the efficiency of the AC system.
   • Clean the air filter: Replace the air filter if it is dirty.
4. Maintenance:
   • Check the refrigerant system: Check for any leaks in the refrigerant system and repair as necessary.
   • Check the fan: Check the fan for proper operation and repair if necessary. The fan is responsible for circulating air through the AC system.
   • Check the ducts: Check the ducts for any signs of damage or leaks and repair as necessary.
5. Testing:
   • Test the AC system: Turn the power back on and test the AC system to ensure that it is operating correctly. Check the refrigerant levels, fan operation, and temperature output.

1. Preparation:
   • Electrical shock: Turning off the power to the AC system prevents electrical shock while servicing the unit.
   • Physical injury: Accessing the AC unit can be physically hazardous if proper safety precautions are not taken, such as using a ladder or scaffold.
2. Inspection:
   • Chemical exposure: Handling refrigerants can be hazardous if proper safety precautions are not taken, such as wearing gloves and eye protection.
   • Physical injury: Inspecting the AC unit involves working at height or in confined spaces, which can be physically hazardous.
3. Cleaning:
   • Chemical exposure: Cleaning the AC unit can result in exposure to cleaning chemicals.
   • Physical injury: Cleaning the AC unit can involve working at height or in confined spaces, which can be physically hazardous.
4. Maintenance:
   • Chemical exposure: Refrigerants can be hazardous if not handled properly. Leaks can result in exposure to refrigerants, which can be toxic.
   • Physical injury: Repairing the refrigerant system, fan, or ducts can be physically hazardous if proper safety precautions are not taken, such as wearing gloves and eye protection.
5. Testing:
   • Electrical shock: Turning on the power to the AC system after servicing it can result in electrical shock if proper safety precautions are not taken.

1. Electrical shock:
   • Turn off the power: Before starting any service work, turn off the power to the AC system to prevent electrical shock.
   • Use proper PPE: Wear rubber gloves and safety glasses to protect against electrical shock.
2. Physical injury:
   • Use proper access equipment: Use a ladder or scaffold to access the AC unit, as needed.
   • Follow manufacturer’s instructions: Follow the manufacturer’s instructions for servicing the AC unit, which may include guidelines for working at height or in confined spaces.
3. Chemical exposure:
   • Wear PPE: Wear gloves and eye protection when handling refrigerants.
   • Follow manufacturer’s instructions: Follow the manufacturer’s instructions for handling refrigerants, including proper disposal methods.
4. Physical injury:
   • Use proper tools: Use the proper tools, such as screwdrivers, pliers, and a refrigerant gauge, to complete the service work.
   • Wear PPE: Wear gloves and safety glasses when repairing the refrigerant system, fan, or ducts.
5. Electrical shock:
   • Turn off the power: Before testing the AC system, turn off the power to prevent electrical shock.
   • Use proper PPE: Wear rubber gloves and safety glasses to protect against electrical shock.
