MEP Life Energy Checklist

This checklist is designed to ensure that all Mechanical, Electrical, and Plumbing (MEP) systems are properly de-energized and locked out before any maintenance, repair, or inspection work begins. This procedure is in accordance with safety regulations and aims to prevent accidental energization and potential harm to workers [1], [2].

Instructions

1. Complete this checklist before starting any work on MEP systems.
2. Verify each item and mark as complete or incomplete.
3. If any item is marked as incomplete, take corrective action before proceeding with the work.
4. Ensure all workers involved are aware of the lock-out/tag-out procedures and their responsibilities [2].

Section 1: Pre-Shutdown Planning

• Identify all energy sources (electrical, mechanical, hydraulic, pneumatic, etc.) [1].
  • Notes:
  • Corrective Actions:
• Review the specific lock-out/tag-out procedure for the equipment [2].
  • Notes:
  • Corrective Actions:
• Gather necessary lock-out/tag-out devices (locks, tags, etc.) [1].
  • Notes:
  • Corrective Actions:
• Ensure all workers are trained and qualified to perform the lock-out/tag-out procedure [2].
  • Notes:
  • Corrective Actions:
• Notify all affected personnel about the planned shutdown [2].
  • Notes:
  • Corrective Actions:

Section 2: Lock-out/Tag-out Procedure

• Shut down the equipment using normal operating procedures [1].
  • Notes:
  • Corrective Actions:
• Isolate all energy sources by disconnecting switches, closing valves, etc. [1].
  • Notes:
  • Corrective Actions:
• Apply lock-out/tag-out devices to each energy-isolating device [1].
  • Notes:
  • Corrective Actions:
• Verify that the equipment is de-energized by testing it. Use appropriate testing equipment to ensure zero energy state [1].
  • Notes:
  • Corrective Actions:
• Ensure that the testing instruments and equipment are visually inspected for defects and damages before use [3].
  • Notes:
  • Corrective Actions:
• Dissipate any stored energy (e.g., release pressure from pneumatic or hydraulic systems) [1].
  • Notes:
  • Corrective Actions:

Section 3: Verification and Communication

• Verify that all energy sources are effectively isolated [4].
  • Notes:
  • Corrective Actions:
• Each worker applies their personal lock to the energy-isolating device [4].
  • Notes:
  • Corrective Actions:
• Post a sign to warn others not to re-energize the system [5].
  • Notes:
  • Corrective Actions:
• Communicate the status of the lock-out/tag-out to all team members [2].
  • Notes:
  • Corrective Actions:

Section 4: Post-Maintenance/Repair

• Inspect the work area to ensure all tools and materials have been removed [6].
  • Notes:
  • Corrective Actions:
• Ensure all workers are clear of the equipment [6].
  • Notes:
  • Corrective Actions:
• Remove lock-out/tag-out devices (only by the person who installed them) [6].
  • Notes:
  • Corrective Actions:
• Notify affected personnel prior to re-energizing the equipment [2].
  • Notes:
  • Corrective Actions:
• Re-energize the equipment and verify normal operation [2].
  • Notes:
  • Corrective Actions:

Section 5: Specific System Checks

Electrical Systems:

• Verify that all electrical connections are properly secured [7].
  • Notes:
  • Corrective Actions:
• Check for any exposed or damaged wiring [7].
  • Notes:
  • Corrective Actions:
• Ensure that all electrical panels are properly closed and secured [7].
  • Notes:
  • Corrective Actions:

Mechanical Systems:

• Verify that all mechanical guards are in place and functioning correctly [1].
  • Notes:
  • Corrective Actions:
• Check for any leaks in hydraulic or pneumatic lines [1].
  • Notes:
  • Corrective Actions:
• Ensure that all moving parts are properly lubricated [1].
  • Notes:
  • Corrective Actions:

Plumbing Systems:

• Check for any leaks in water or gas lines [6].
  • Notes:
  • Corrective Actions:
• Verify that all pipe supports are in good condition [1].
  • Notes:
  • Corrective Actions:
• Ensure that all drain lines are clear and functioning properly [6].
  • Notes:
  • Corrective Actions:
