A transit fixing is any bolt, bracket, pin, chock or strap fitted to keep a machine still inside the crate and discarded once the machine stands in its room. An operating table can travel with a dozen or more such items: column bolts, a tabletop clamp, castor chocks and a locking pin through the elevation guide. Cutting the strapping takes ten minutes. The fixing list is the only document that states how many items must leave the crate. The paperwork around the fixings decides who pays for damage found in year two. According to IEC 60601-2-46:2023, instructions for use must cover preparation before first use, and 100% of that preparation needs a person and a date once the machine becomes a hospital asset. Of the 3 names on a finished page, 2 (67%) belong to the hospital.
What Counts as a Transit Fixing on an Operating Table?
A transit fixing is a temporary restraint rather than a component, and the machine works only after the restraint has gone. Six categories cover most deliveries. First, bolts running through the base frame into the pallet. Second, a clamp or bracket locking the tabletop to the column. Third, castor chocks or timber shipping blocks. Fourth, a pin through the elevation guide or the hydraulic ram. Fifth, clips holding the head, leg or back sections closed. Sixth, foam wedges and stretch film pressing on pads and side rails. Three of the 6 categories (50%) sit below the tabletop, where nobody looks once the crate is open, and the drawing must show 100% of the set. According to ISO 13485:2016, installation activities require documented requirements and records. A 2026 order should name all 6 categories and the count behind each one.
Why Must Removal Finish Before the First Power-On?
First power-on is the moment when every transit restraint must already be gone, because powered metal against locked metal fails quietly. A column driven against a locked guide stalls the actuator. Supply current climbs, the controller logs an overcurrent fault, and the limit switch never reports the low position. Four failure modes follow from a fixing left in place, and 2 of the 4 (50%) announce themselves as a fault code on the first switch-on. The other 2 appear as a gap, a tilt or an arm that moves when the brake releases. A pin left in a pendant or light arm is the dangerous case, because stored spring force releases the moment power reaches the brake. According to IEC 60601-2-46:2023, the table must hold every position in its declared range, so 100% of the fixings belong on the checklist. Finally, one signature releases the mains switch.
Who Removes the Fixings: BMET or the Supplier Engineer?
Fixing removal is a three-party act, and each party owns a different step. Riggers or the main contractor move the crate into the room and strip the outer packing, and 1 of the 3 (33%) will usually offer to finish the job with a spanner. The supplier’s field service engineer removes the fixings to the manufacturer’s procedure, because torque, sequence and re-use rules belong to the design. The hospital’s biomedical equipment technician, shortened to BMET, witnesses the removal, counts the items against the drawing and confirms the floor around the unit is clear. According to 21 CFR 820.170, installation follows the manufacturer’s instructions and is inspected afterwards, with the inspection recorded. A 2026 order naming all 3 roles ends the argument about who was meant to take the last bolt out, and 2 of the 3 parties (67%) sign the same certificate line.
The Two Signatures and What Each One Certifies
A signature pair is two certifications on one line, and each name answers a different question. First, the remover certifies every item on the drawing as removed and bagged, and records the tabletop moving through the full hand range where the design allows hand movement. Second, the BMET certifies the count against the drawing, the tags against the fixing numbers, and the absence of any obstruction in a hole, thread or clamp. According to ISO 13485:2016, installation and verification must be recorded, so 100% of the evidence rests on the pairing rather than on either name alone. Two names, 1 date and 1 serial number also survive staff turnover. For example, a bolt found in a drawer at year three is answered by the pairing, not by memory. The pairing costs 2 minutes per unit.
What Must the Fixing Location Diagram Show?
A fixing diagram is an audit tool, and the test is whether a stranger can verify the machine in minutes. Each fixing appears twice, so 100% of the set is checkable against the hardware. The number appears as a callout on the drawing and as a tag or coloured cap on the table. First, the drawing states the count per position. Second, the drawing names the tool required. Third, the drawing states whether the item is discarded or returned, plus the direction of removal where a thread or taper is involved. Twelve callouts on 1 sheet beat 4 photographs taken from a distance, because a photograph proves a view while a callout proves completeness. According to ISO 14971:2019, every risk control measure needs verification of implementation, and the sheet is the verification tool for a fixing left in place. A 2026 revision should reissue the sheet when the model changes.
The Removal Log: Six Columns That Survive an Audit
A removal log is a per-unit table rather than a paragraph inside a site report, and the log is what a surveyor reads after the crew has gone. First, four of the 6 columns (67%) are filled at the machine: fixing number, removal time, remover name, bag or tag number. Second, 2 are filled at a desk, where the certificate is assembled: witness signature and power-on release. According to 21 CFR 820.170, installation is inspected and the inspection documented, so a log with a gap is a finding rather than a clerical slip. One row per fixing, 1 certificate per unit and 100% of units in a 2026 delivery deserve their own sheet, because fleets fail one unit at a time. A log that names nobody proves nothing, and the log stays on 1 sheet because a second sheet gets lost.
What Goes in Each Column of the Removal Log
A removal log column is one field with one job, and the 6 fields below run in the order a crew fills them. Each field holds evidence that a different person can test, which is why a blank cell is a missing check rather than a formatting choice. The table lists the field, the evidence held and the question an auditor asks, so a reader can see where a 2026 handover pack would fail.
| Log field | Evidence held | Auditor question |
|---|---|---|
| Fixing number | Callout number from the location drawing | Does the drawing match the model delivered |
| Date and time | Removal timestamp, to the hour | Did removal precede the power-on release |
| Remover name | Engineer name, employer and signature | Was the remover trained on this procedure |
| Bag and tag number | Sealed bag label with site, room and serial | Can the removed parts be produced on request |
| Witness signature | BMET name and signature, count confirmed | Did a second person verify the count |
| Power-on release | Name, role and date of the energising permit | Who authorised first power, and on what basis |
Where Do the Removed Fixings and the Papers Go?
The archive is three destinations, not one, and mixing the destinations loses the argument. First, the fixings go into 1 tagged bag per unit, labelled with site, room, model, serial and fixing number, because a bolt found later is either a spare part or a smoking gun. Second, the certificate row goes into the equipment file, the asset record the BMET keeps for the working life of the machine. Third, a one-line entry goes into the room handover dossier that the OR installation interface pack and the unit acceptance record both reference. According to 21 CFR 820.180, records are kept for at least 2 years from release, and 1 of the 3 destinations (33%) usually outlives the warranty. A 2026 audit tracing bag, certificate and handover line to one serial number closes 100% of the three at once.
How Does the Removal Date Move the Warranty Start?
Warranty start is a date chosen by contract, and only 3 of the 4 candidate events (75%) belong to the hospital. The ship date belongs to the factory, and 1 of the 4 (25%) is the only date the hospital cannot influence. The delivery date belongs to the receiving dock and the freight forwarder. The commissioning date belongs to the engineer who signed the removal. The first clinical use date belongs to the theatre team. An annex starting at shipment gives away weeks of cover while the crate waits for a finished room, which is why storage terms that protect the warranty belong on the same page. According to ISO 13485:2016, installation records form part of the device history, so the date survives a claim. Finally, one signed sheet moves the clock to a 2026 day the hospital can prove.
What Should the Order Say About Fixing Removal?
The order clause is a one-line requirement that names an artefact rather than an intention, and 5 clauses cover the fixing record. Three of the 5 (60%) are factory deliverables, and 2 depend on the hospital’s own signature.
- Clause 1. Fixing schedule. A numbered drawing per model, issued before shipment, with count, tool and discard rule per position.
- Clause 2. Removal procedure. Work performed by the supplier’s engineer to the instructions for use, witnessed by the BMET, with 2 signatures on 1 line.
- Clause 3. Release gate. No unit is energised before the certificate is signed, and the release entry carries a name, a role and a date.
- Clause 4. Bag and tag. 100% of removed items travel with the unit, labelled by fixing number, never discarded on site.
- Clause 5. Warranty link. The start date follows signed commissioning rather than the bill of lading, and the receiving protocol records the crate condition on the same page.
According to ISO 13485:2016, none of the 5 lines is unusual; each is a record the quality system already expects.
What Does the One-Page Certificate Actually Prove?
A commissioning certificate is 1 page per unit carrying serial, model, room, 12 fixing numbers, 2 signatures, 1 release date and the bag number. The page answers the first question a service engineer asks six months later: was this unit ever energised with a fixing still in place? According to IEC 60601-2-46:2023, the manufacturer must state preparation before use, and the page is where the hospital proves the statement was followed. Three names are enough: remover, witness and release. The page also settles cost, because 1 witnessed hour of removal prevents an actuator replacement that can take weeks to arrive. A 2026 handover pack containing the page closes the gap between crate and clinic, and 100% of the units in a first delivery should carry one. Finally, a column fault code becomes a one-line check.
