Bottom Loading Rack Pre-Operation Audit

Pre-operation inspection for a bottom loading rack covering interlocks, vapor recovery, emergency stop systems, and earth ground verification.

Pre-Operation Readiness

• Loading rack identified and available for operation
  Verify the correct bay/rack is selected, clearly identified, and not tagged out of service.
• Area free of spills, leaks, obstructions, and ignition sources
  Inspect the immediate loading area for product spills, standing liquid, blocked access, and unauthorized ignition sources.
• Required PPE available and worn
  Confirm personnel are wearing site-required PPE for loading operations, such as eye protection, gloves, flame-resistant clothing, and safety footwear as applicable.
• Pre-operation checklist and SOP available at rack
  Verify the current operating procedure, emergency response instructions, and site-specific loading checklist are available to the operator.
• No active alarms or unresolved maintenance defects
  Confirm the control system, local indicators, and maintenance status do not show unresolved faults that would prevent safe loading.

Interlocks and Control Permissives

• Vehicle presence or bay permissive interlock functions correctly
  Confirm the loading sequence only enables when the required vehicle/bay permissive condition is satisfied.
• Overfill prevention interlock functional
  Verify the overfill protection system, probe, or shutdown permissive prevents loading when the high-level condition is simulated or indicated.
• Ground verification permissive enabled before loading authorization
  Confirm the system does not permit loading until the grounding/bonding verification signal is present and stable.
• Hose connection or arm position interlock functional
  Verify the loading sequence is inhibited unless the hose, arm, or coupler is correctly connected and in the proper position.
• Interlock bypasses or overrides are absent or authorized
  Check for any bypassed, defeated, or overridden safety interlocks. If present, confirm they are authorized, documented, and controlled per site procedure.

Vapor Recovery System

• Vapor recovery hose/arm connected and secure
  Verify the vapor recovery connection is properly attached, sealed, and free from visible damage or leakage.
• Vapor recovery valves and couplings in serviceable condition
  Inspect valves, couplings, gaskets, and fittings for wear, cracks, missing parts, or signs of leakage.
• Vapor recovery pressure or flow indication normal
  Confirm local indicators or control system readings show normal vapor recovery operation within site acceptable limits.
• No visible vapor leaks or abnormal odor at rack
  Observe the loading point, vapor return connection, and associated piping for visible vapor release or unusual odor.
• Vapor recovery system ready for transfer
  Confirm the system is not isolated, blocked, or otherwise unavailable for the planned loading operation.

Emergency Stop and Safety Devices

• Emergency stop devices accessible and unobstructed
  Confirm all required E-stops can be reached quickly and are not blocked by vehicles, hoses, equipment, or debris.
• Emergency stop labels and identification legible
  Verify each emergency stop is clearly marked and visible from the operator position.
• Emergency stop function tested and confirmed
  Test the emergency stop circuit per site procedure to confirm it stops or isolates loading as intended.
• Fire extinguisher present, accessible, and in date
  Verify required fire extinguishers are present at the rack, accessible, and within inspection/service date.
• Emergency lighting or alarm indication operational
  Confirm any required emergency lighting, audible alarm, or status indication associated with the rack is functional.

Earth Ground and Bonding

• Earth ground connection intact and secure
  Inspect the ground clamp, cable, and connection point for secure attachment, corrosion, damage, or looseness.
• Ground verification indicator shows acceptable status
  Confirm the grounding verification system indicates a valid ground condition before loading is authorized.
• Bonding cable or jumper present where required
  Verify bonding equipment is installed and connected according to site procedure for the product and transfer setup.
• Grounding test result recorded
  Record the measured grounding or continuity result if required by site procedure.

Deficiencies and Signoff

• Deficiencies identified
  Record any deficiencies, non-conformances, or critical items that prevented startup.
• Corrective actions completed or escalated
  Document corrective action taken, work order number, or escalation details for unresolved issues.
• Inspector signature
  Inspector signs to confirm the pre-operation audit is complete and accurate.
