A pre-operation inspection is the structured visual review performed at the jobsite immediately before applying compressed air — confirming that the tool, air delivery path, work area, documentation, and crew are ready for safe operation according to current manufacturer guidance and jobsite requirements.
This checklist is a general planning aid and does not replace the current BORVEX technical documentation, applicable regulations, utility locating, permits, operator training, or a jobsite-specific risk assessment.
Purpose of pre-operation inspection
Pre-operation inspection is the last structured review before compressed air energizes the tool. It catches visible conditions — damaged hose, unclear utility clearance, missing documentation, unprepared launch pits — that are easier to resolve before the run than after a stall or safety concern mid-bore.
This checklist supports consistent crew habits across fleets and jobsites. It is a planning aid for visual review only. It does not replace operator training, utility locating, permits, published BORVEX technical documentation, or a jobsite-specific risk assessment.
When any stop condition is observed during inspection, secure the equipment and resolve the concern or contact qualified technical support before continuing.
When to perform the inspection
Complete the checklist after the tool, compressor, and hose are staged at the launch area but before connecting final air supply and beginning the bore.
Repeat relevant items if conditions change during the workday — hose rerouting, compressor swap, pit modification, weather change, or crew turnover may invalidate an earlier review.
Do not treat a checklist completed at the shop or during transport as a substitute for jobsite review at the launch point.
Equipment visual review
Confirm tool identity matches the planned model for the crossing. Verify that external condition is acceptable — no visible cracks, significant dents, damaged threads, or missing identification labels.
Review the nose section and body for contamination at connection areas. Confirm externally accessible fasteners and handling points appear secure without attempting internal disassembly.
If the tool was transported on an open trailer or shared space with other cargo, re-inspect external condition after unloading before connecting air.
Air supply visual review
Inspect the full delivery path from compressor outlet to tool inlet. Hose sections should be free of cuts, kinks, bulges, and visible reinforcement damage. Couplings and fittings should be compatible, sealed, and appropriate for the service.
Confirm hose routing is secured to reduce tripping hazards, abrasion against pit edges, and kinking from crew movement during the run.
Compare visible compressor and hose configuration against planning assumptions — length, inside diameter, and fitting count. Unexpected changes from the planned setup may affect delivery.
Jobsite readiness
Launch and receiving pits should match planned depth, alignment, and access for the selected method. Surface obstructions, traffic control, and exclusion zones should be established before operation begins.
Utility locates and clearance review should be complete for the planned bore path — not only at pit locations. Document any field marks, conflicting utilities, or alignment adjustments made after initial planning.
Environmental conditions — standing water, unstable pit walls, frozen ground, or visibility limits — should be assessed for their effect on safe operation before air is applied.
Documentation at the jobsite
Current BORVEX technical documentation for the specific model should be accessible to the responsible operator or foreman — whether in digital or printed form.
Project-specific requirements — bore distance, conduit size, depth, alignment, permit conditions — should be confirmed against the work order or field instructions before starting.
When documentation is missing, outdated, or inconsistent with the staged equipment, stop and obtain verified references before operation.
Crew readiness
Confirm that personnel assigned to the operation understand launch and receiving roles, communication signals, exclusion zones, and stop conditions.
Operators should be familiar with the specific model being deployed — not only a generic pneumatic tool category. Cross-training is valuable, but first-time operation of an unfamiliar model warrants additional review against published guidance.
Verify that required personal protective equipment and jobsite safety requirements are in place before energizing compressed air.
Stop conditions during inspection
Do not proceed when any of the following are observed during pre-operation inspection. Resolve the condition or contact qualified technical support first.
- Visible tool damage, deformation, or missing identification
- Damaged, kinked, or patched pressure hose in the delivery path
- Incompatible, leaking, or improvised air connections
- Incomplete utility locates or unresolved clearance concerns along the bore path
- Launch or receiving pit conditions that do not match planned alignment or depth
- Missing or uncertain technical documentation for the staged model
- Crew uncertainty about roles, signals, or stop procedures
- Any condition where continuing may create safety risk to personnel or equipment
After inspection — before starting
When the checklist is complete and no stop conditions apply, confirm communication between launch and receiving personnel, verify exclusion zones are respected, and apply air according to published operating guidance for the specific model.
Continue monitoring external hose routing, compressor behavior, and tool response during initial cycling. Stop immediately if unexpected sound, leakage, or behavior appears after startup.
Record inspection completion and any field notes in fleet or jobsite logs when your organization maintains such records.
Relationship to preventive maintenance
Pre-operation inspection complements broader preventive maintenance planning. Fleet-level maintenance addresses intervals, documentation libraries, and wear history across multiple jobs.
The jobsite checklist focuses on conditions visible today — at this pit, with this compressor, and this crew. Both practices support reliability without substituting for authorized service when internal concerns exist.
Pre-operation visual inspection checklist
Visual review only — complete at the launch area before applying compressed air. Stop and contact qualified technical support if any stop condition is observed.
