| DECOMMISSIONING AND REMOVAL OF ELECTRICAL INSTALLATION |
"Risk Assessment for Decommissioning and Removal of electrical installations" involves electrical Installations safely disconnecting, dismantling, and disposing of electrical systems, equipment, and wiring. This process ensures compliance with safety standards, minimizing risks such as electrical shocks, fires, or environmental hazards. It includes isolating power sources, following proper waste disposal methods, and restoring the site to a safe condition. Adhering to QHSE protocols ensures the activity is conducted responsibly and efficiently.
1.0. HAZARDS
1.1. Contact with the live electrical conductor
1.2. Accidental or unauthorized livening of the circuit
1.3. Contact with services
2.0. RISKS & CONSEQUENCES
2.1. Electric Shock
2.2. Direct contact with a live conductor can cause an electric shock. It may result in muscle contraction, respiratory arrest, or cardiac arrhythmia.
2.3. Burn Injuries
2.4. High-voltage contact can cause severe burns at entry and exit points of the electrical current.
2.5. Can lead to permanent scarring, tissue damage, or amputation.
2.6. Fire Hazards
2.7. Contact with a live conductor could ignite surrounding flammable materials.
2.8. Can result in property damage or injury to personnel due to fire.
2.9. Secondary Injuries
2.10. An electrical shock may cause the person to lose balance and fall.
2.11. May lead to fractures, head injuries, or other physical harm.
2.12. Equipment Damage and Downtime
2.13. Accidental contact with a live conductor may short-circuit or damage critical equipment.
2.14. Operational delays, financial loss, or production stoppages.
2.15. Electrical Shock to Personnel
2.16. Individuals working on or near the circuit may accidentally come into contact with live components.
2.17. Severe injury or fatality due to electrical shock, ranging from burns to cardiac arrest.
2.18. Arc Flash Incident
2.19. Unauthorized energizing can lead to an arc flash when tools or conductive materials are in proximity to the circuit.
2.20. Serious burns, hearing loss, eye damage, or even death, alongside potential damage to nearby equipment.
2.21. Fire Outbreak
2.22. Overloaded circuits or exposed wiring may ignite due to sudden energizing.
2.23. Fire leads to property damage, environmental hazards, and life-threatening conditions for personnel.
2.24. Damage to Equipment
2.25. Sensitive electrical or electronic equipment may be subjected to unintended voltage or current.
2.26. Permanent damage or malfunction of equipment, leading to downtime and financial loss.
2.27. Non-compliance with Safety Protocols
2.28. Violation of lockout/tagout (LOTO) procedures or similar safety standards during maintenance.
2.29. Regulatory penalties, loss of client trust, and reputational damage for the organization.
2.30. Contact with live electrical cables
2.31. Accidental drilling, cutting, or digging into live electrical cables during construction or maintenance work.
2.32. Electric shock or electrocution causing serious injury or fatality.
2.33. Damage to equipment or tools leads to operational delays.
2.34. Fire or explosion due to electrical arcs.
2.35. Damage to underground gas pipelines
2.36. Excavation activities without accurate service maps or using improper tools.
2.37. Gas leaks lead to a potential explosion or fire.
2.38. Toxic gas exposure causes respiratory health issues for workers and nearby individuals.
2.39. Large-scale evacuation and financial loss due to emergency response measures.
2.40. Rupture of water mains
2.41. Digging into unmarked or incorrectly marked water pipelines.
2.42. Flooding at the worksite causes equipment damage and increases safety risks like slips or falls.
2.43. Disruption to the water supply for nearby areas, impacting businesses and communities.
2.44. Prolonged project delays and additional repair costs.
2.45. Cutting through communication cables
2.46. Lack of proper identification of fiber-optic or telecommunication cables before excavation.
2.47. Disruption to essential communication services, affecting businesses and emergency response systems.
2.48. High repair costs and penalties for service disruption.
2.49. Damage to the company's reputation due to service outages.
2.50. Inadvertent contact with sewage systems
2.51. Damaging or puncturing underground sewer lines during excavation or groundwork.
2.52. Contamination of the worksite with hazardous waste leads to health risks (e.g., infections, and diseases).
2.53. Environmental pollution requires cleanup efforts and penalties.
2.54. Delays in work and increased project costs due to emergency repair efforts.
3.0. EXISTING RISK CONTROL MEASURES
3.1. Where practical, the electrician is to be the sole key holder to the room of decommissioning. Work to be carried out within an exclusion zone.
3.2. The work area is to be signed as live until decommissioned.
3.3. To reduce the risk of accidental/unauthorized livening of the circuit, cables are to be removed
3.4. Only trained Electrical Engineers are to work on the decommissioning of the installation.
3.5. Work on access routes to be restricted to others and subject to permit to work / entry system.
3.6. All circuit boards within the panel are to be isolated at the main distribution board isolators and locked off with a pin and padlock.
3.7. Removal work is only to commence with everything dead.
3.8. Building plans, and scans are to be used to identify live services.
3.9. Isolate the services to the decommissioning area before work commences.
3.10. Carefully locate any live services and identify them at the earliest convenience (only if unable to isolate).
4.0. ADDITIONAL RISK CONTROLS
4.1. [COMPANY] Management to monitor exclusion zone and permit to work / entry system is maintained throughout the work.
4.2. [COMPANY] Supervisor to monitor the locking-off system.
4.3. [COMPANY] Management to ensure suitable service drawings and scanning devices are available.
