Safety Inspection Workload at 18% access, lockout, and documentation allowance: a worked example

Suppose access, lockout, and documentation allowance falls to 18%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Estimate safety inspection workload from inspection points, inspector throughput, and allowance for lockout, pressure checks, leak checks, and documentation.

The inputs for this scenario

  • Gas system inspection points: 90 inspection points (held at the documented default)
  • Inspection points completed per hour: 12 inspection points / hr (held at the documented default)
  • Access, lockout, and documentation allowance: 18 % (the input this scenario stresses; the baseline uses 25)

Working through the calculation

  • The calculation starts from the formula this tool documents: Base safety inspection workload = gas system inspection points รท inspection points completed per hour.
  • Required safety inspection workload works out to 8.85 hr at these inputs, and this is the headline figure for the scenario.
  • Base safety inspection workload works out to 7.5 hr at these inputs.
  • Access, lockout, and documentation allowance works out to 18 % at these inputs.
  • Inspection points completed per hour works out to 12 pieces / min at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where access, lockout, and documentation allowance sits at 25% and the headline result is 9.38 hr, this scenario comes in 5.6% below the baseline at 8.85 hr.
  • It computes required safety inspection workload in hours as base inspection time scaled up by an access, lockout, and documentation allowance. When the numbers land here, the stressed input is the lever to work; the walkthrough above shows exactly how much each output recovers as it climbs back toward the baseline.

Results at a glance

  • Required safety inspection workload: 8.85 hr (headline result)
  • Base safety inspection workload: 7.5 hr
  • Access, lockout, and documentation allowance: 18 %
  • Inspection points completed per hour: 12 pieces / min
