About this ITP: This ITP defines inspections and tests for safe removal of mercury-contaminated piping, including gas-free verification, enclosure performance, monitoring, packaging, and clearance.

More than a static template

Unlike a downloadable Word or PDF template, this ITP is an AI-assisted editable starting point directly connected to its method statement. Every inspection activity, hold point, and acceptance criterion is structured and ready to adapt to your project.

  • AI-assisted customization — Tailor inspection activities and acceptance criteria to your specific project scope.
  • Linked method statement — This ITP is connected to the corresponding method statement describing the work sequence.
  • Multiple export formats — Download as a formatted PDF or editable Excel spreadsheet.
  • Editable starting point, not a final document — Review and verify all content against your project specifications and standards before use.

What you can customize

When you save this ITP to your account, every inspection row becomes editable. You can add, remove, or modify:

  • Inspection activity — Description of what is being inspected.
  • Inspection type — Hold point (H), Witness point (W), Review (R), or Monitor (M).
  • Responsibility — Contractor, subcontractor, engineer, or client.
  • Frequency — How often the inspection occurs.
  • Acceptance criteria — Referenced standard or specification requirement.
  • Records — Forms, test reports, or checklists required as evidence.

Why this ITP is used

To control and verify safety, environmental, and quality requirements during hazardous pipe removal operations.

Who uses this inspection and test plan

Project and construction managers, gas operations, industrial hygienists, HSE, QA/QC, and waste specialists.

When this ITP is prepared and submitted

From pre-start through removal, packaging, and final clearance before demobilization.

Who receives or approves this ITP

The ITP is usually submitted to the client representative, consultant, resident engineer, or project management consultant for review and approval before the related work activity starts.

Inspection scope

Permits and documentation, isolation and purging, containment performance, continuous monitoring, cutting and capping, waste packaging, and clearance testing.

Typical hold, witness, and review points

Gas-free/inert status; enclosure negative pressure verification; first cut; capping and leak check; clearance monitoring sign-off.

Typical inspection records

Calibration logs, gas test logs, monitoring records, torque/leak records, waste manifests, chain-of-custody, clearance certificates.

Important approval note

This ITP is an AI-assisted editable starting point, not a pre-approved document. Before use on any project, all inspection activities, hold points, and acceptance criteria must be reviewed and approved by the relevant parties (superintendent, principal contractor, or client representative) in accordance with your contract and project quality plan.

Always verify acceptance criteria against your applicable drawings, specifications, and regulatory requirements. Hold points must be confirmed with the relevant authority before work proceeds past that point.

Inspection and test plan

Activity Inspection / Test Acceptance Criteria Responsibility Record
Pre-start documentation and permits Approved RAMS, permits, LOTO plan, calibration certs available All approvals in place; documents current Project Manager / HSE Manager ITP sign-off; permit copies
Instrument daily checks Zero/span or bump tests per OEM Within OEM tolerance Industrial Hygienist / QA-QC Calibration/bump logs
LOTO and isolation verification Physical check of valves/tags; pressure gauge at 0 barg Isolation confirmed; 0 barg Gas Operations Supervisor LOTO log; isolation certificate
Gas-free/inert status LEL reading; methane; O2 inside pipe LEL 0%; O2 <8% inside pipe; ambient O2 19.5–23.5% Authorised Gas Tester Gas-free certificate
Enclosure integrity and negative pressure Smoke test; manometer reading No leaks; -5 to -10 Pa maintained Piping Supervisor / HSE Enclosure checklist
Baseline mercury/perimeter readings Hg vapour at perimeter and inside enclosure Perimeter < action level (typically 50% of OEL) [Verify] Industrial Hygienist Monitoring log
Cold cutting operation monitoring Continuous/periodic Hg, LEL, O2 readings during cut No exceedance of action/stop levels; LEL 0% Industrial Hygienist / Supervisor Monitoring log; shift report
Capping and leak check Torque values; soap solution leak check Torque within spec; no bubbles Piping Supervisor Torque/leak records
Waste packaging inspection UN drum markings; liner integrity; labeling; closure Compliant per DG rules; secure closure Environmental Specialist / QA-QC Drum packing list; photos
Clearance air monitoring Real-time Hg; confirmatory sorbent tube if specified ≤ project clearance criterion (typ. ≤10 µg/m³) [Verify] Industrial Hygienist Clearance certificate; lab report

Frequently asked questions

Gas-free/inert certification before any cutting and final clearance monitoring are typical hold points requiring owner/operator approval.

Not always. Real-time monitoring may suffice; however, confirmatory sorbent tube or wipe samples may be required by the specification or regulator.
