- Safety Precautions
- Conduct a site risk assessment before commencing work.
- Ensure all workers wear appropriate PPE at all times.
- Mark the work area with warning signs and barriers.
- De-energize the system during installation to prevent accidental shock.
- Ensure proper grounding of the system to avoid electrical hazards.
- Only trained and certified personnel should handle the electrical components.
- Procedure
6.1 Site Preparation
- Survey the Site: Mark the perimeter where the electric fence will be installed. Identify any potential obstacles or hazards.
- Clear the Area: Remove vegetation, debris, or any obstructions along the fence line.
6.2 Post Installation
- Install Posts: Place the posts in the holes, ensuring they are vertically aligned
- Install Corner and End Posts: Ensure that these posts are stronger and more stable, as they will bear the most tension.
6.3 Wire Installation
- Install Insulators: Attach insulators to the posts at the specified heights. These will hold the wires and prevent grounding.
- String the Wires: Begin at one corner and run the wire through the insulators along the fence line. Ensure the wire is taut and secure it at each end post.
- Tension the Wires: Use a wire tensioner to ensure the wires are properly tensioned. Check for even spacing between wires.
- Install Additional Components: Install danger hatari warning signs
6.4 Energizer Installation
- Mount the Energizer: Install the energizer in a secure, dry location, protected from the elements. Follow the manufacturer’s instructions for mounting and connection.
- Connect the Wires: Attach the fence wires to the energizer terminals according to the wiring diagram provided by the manufacturer.
- Install Grounding Rods: Drive the grounding rods into the ground near the energizer. Connect these to the energizer using grounding wire.
6.5 Testing and Commissioning of Electric Fence Installation in Kenya
- Inspect the System: Check all connections, wire tension, and component installation for compliance with the project specifications.
- Test the Energizer: Power on the energizer and use a voltmeter to ensure the system is functioning correctly. Check for consistent voltage along the entire fence line.
- Install Warning Signs: Place warning signs at regular intervals along the fence, in compliance with safety regulations.
6.6 Handover and Documentation
- Final Inspection: Conduct a final inspection with the client to ensure satisfaction with the installation.
- Provide Documentation: Deliver all relevant documentation, including user manuals, maintenance instructions, and warranty information.
- Training: Provide basic training to the client on operating and maintaining the electric fence system.
- Quality Control
- Conduct regular inspections throughout the installation process.
- Document all work completed, including any deviations from the original plan.
- Emergency Procedures
- In case of electrical shock, immediately de-energize the system and administer first aid.
- For any accidents or incidents, report to the Safety Officer and follow emergency response procedures.
- Completion and Handover of Electric Fence Installation in Kenya
Upon completion of the installation, ensure the work area is clean and all tools and equipment are removed. Handover the completed electric fence system to the client, ensuring they are fully informed of its operation and maintenance requirements.
