A shift change on a route fleet is not a pause in the work; it is the moment the evidence is judged. The next crew takes the vehicles, the depot manager signs for them, and the provider's paperwork either holds up or it does not. Between two shifts there is no time to reconstruct what was done, so the record has to be written while the work is happening. This article sets out the records a cleaning provider should have agreed before the first vehicle of a contract is touched, using the published data of a fixed steam unit as the reference for the site survey.
What the shift record has to prove before the fleet leaves the depot
Fleet work runs in groups, not one vehicle at a time, because the window is set by the next departure rather than by the crew. A usable record opens with a scope table that splits the fleet into groups the customer recognises: tractors and rigid trucks, trailers and box bodies, tankers and bulk carriers, vans and light commercial vehicles, and specialised body work such as refrigerated units. For each group the table states what a cleaned vehicle includes, what is excluded, and who decides when the two sides disagree.
Put three names on every line: the operator who did the work, the supervisor who walked the vehicle afterwards, and the depot or transport representative who accepted it. Where the customer will not sign at the gate, the procedure has to say what happens instead: a dated photo set with a naming rule, a named witness, and an incident line that records the vehicle and the reason for the refusal. A procedure with no fallback for an unsigned hand-back fails the first time a driver leaves early.
Write the failure path too. A vehicle that does not pass the walk-round needs a status, a rework slot or a written deferral, and a note of whether it was released under exception. Without that line the provider either cleans twice inside the same window or releases something the customer reports the following morning.
Survey the site before the shift: utilities and machine placement
Get the data sheet from the supplier, then walk the yard holding it. A fixed unit such as the Fixed Steam Cleaning Machine PowerDe HW02 publishes everything the survey has to accommodate: a 220 V supply, 6 kW heating power, a steam temperature of 160 degrees Celsius, a vapour pressure of 0.8 MPa, an 80 L tank in SUS304, a footprint of 1,200 x 800 x 1,200 mm including handles, and a tap-water inlet with a 4-point internal-tooth joint of 1/2 inch. Each of those becomes a question with an answer you can check.
- Is there a 220 V point within reach of the standing position, on a circuit that will not trip when other yard equipment starts?
- Where is the tap, does it carry mains pressure, and does the site hose connection match the 1/2 inch inlet fitting?
- Can the 80 L tank be refilled where the machine stands, or does someone carry water across the yard mid-shift?
- Which drain takes the run-off, is it inside the work zone, and who controls that drainage route at this site?
- Is there hard standing that fits 1,200 x 800 x 1,200 mm, keeps the unit clear of the reversing lane, and is lit at the hour the shift starts?
Date the survey, name the person who walked the site, and attach the machine serial number it applies to. A survey without a serial number cannot be reused when a second unit goes onto the same site. Anything the data sheet does not answer, such as supply per hour, running time on a fill, wand and hose reach, weight and noise, goes into a written request to the supplier and stays open; do not fill those gaps with estimates inside a method statement.
A mobile steam cleaning machine changes the survey rather than cancelling it. The cleaning point moves to the vehicle, which matters where the yard is shared with loading operations, and the record then adds the travel route, the bay used, whether the unit was moved during the shift, and who moved it.
What each vehicle group gets: the line items the record states
The quotation and the shift record should use the same words. Break every vehicle into areas the log can tick and state the mode used for each. The published duty list for the fixed unit covers vehicle exterior cleaning at gas stations and parking lots, interior vacuuming and disinfection, and engine-compartment cleaning; those three lines can be quoted against the machine page. Anything beyond them needs written confirmation before it appears in a procedure.
- Exterior panels, including the cab rear, door edges, steps and mirror mounts, with the pass order recorded.
- Cab interior: vacuuming, high-touch surfaces, and a note of what was disinfected and what was only cleaned.
- Engine compartment, marked cleaned or skipped, with the reason for a skip.
- Wheels, arches and the underside of the chassis rails, where road grime accumulates fastest.
- Box bodies, curtains, tail lifts and refrigerated unit exteriors, which hold film in rails and hinges.
- Tankers and bulk carriers, with a line naming what the tank last carried, because that changes the residue and the disposal route.
State the mode in the log. Dry steam, wet steam and hot water are different jobs: one leaves almost no run-off, the next loosens film, the third carries heat and volume into the drainage route. A record that says only "cleaned" cannot answer a complaint about residue, wet paint, or water where the customer says it should have stayed dry.
Write down what is never sprayed, on the sheet the operator carries: electrical connectors and junction boxes, air intakes, bearings and seal ends, camera and sensor housings, decal edges and repairs, and any area the vehicle owner has flagged. Those exclusions are what make engine-compartment work possible at all, and they are the first thing a customer asks for after a fault is reported.
The cleaning log: the fields a fleet customer signs
A fleet log is a table, not an account of the day. Keep it to fields that can be filled in a cab or on a tail lift inside a minute, because a longer form will not be completed under shift pressure. Commercial vehicle steam washing equipment is bought on throughput, so the log has to survive being filled at throughput.
- Vehicle identifier: plate or fleet number, plus the group it belongs to in the scope table.
- Start and finish time for that vehicle, so the shift reconciles against the departure board.
- Areas completed, area by area, with the mode used for each.
- Operator and supervisor names, initialled against each vehicle rather than once at the foot of the sheet.
- Utility note: refills, drain used, whether the machine had to be moved.
- Defects seen during cleaning: cracked mudguard, loose step, damaged seal, warning light, damage already present.
- Exceptions: what was not done, why, and whether the vehicle was released under exception or held.
Defects are worth as much as the cleaning. A driver told that a seal looks torn before the wheel is turned will forgive a missed corner; a driver who finds it afterwards disputes the contract. Record who reported each defect and to whom, and send that line to the customer the same day instead of bundling it into a weekly report.
Set the photo rule in writing: which angles, how the file is named against the vehicle identifier, and how long the images are kept. A photo set without a naming rule is unusable in a dispute six weeks later.
Where the log and the quotation have to agree
Every line the operator fills in should already exist in the quotation as a priced item, and every priced item should have a place in the log. That is the test to run before the contract starts. Put the quotation and the log side by side: any priced duty with no log field is work the crew will quietly drop, and any log field with no priced duty is work the provider is giving away.
Hand-back between two departures
Hand-back is a walk-round with the log open, not a wave. The supervisor ticks the areas and the driver countersigns. Where a surface is still wet, the shift needs a drying slot planned into it rather than an assumption that it will dry on the way to the gate; the published data does not state drying times, so the provider measures them on their own fleet during the trial and writes the measured figure into the method statement.
Cut-off rules matter more than speed. State the latest time a vehicle can be started and still be finished, recorded and signed before its departure, and state what happens to a late arrival: held for the next shift with written notice, or cleaned and released unsigned. A site with neither rule will run two unfinished vehicles into the following morning, and both will be blamed on the provider.
Close the shift with a one-page summary: vehicles in, vehicles cleaned, vehicles held or deferred, defects reported, machine faults, and any utility problem such as a drain that backed up. That page is what the depot manager reads; the per-vehicle logs are the evidence behind it.
Stop rules, protection items and escalation
The product page for the fixed unit lists leakage, short-circuit, high-temperature, high-voltage, water-shortage and high-voltage-explosion protection. Treat each as a stop condition with an action: stop, tag the machine, record the fault, move to a standby unit or a manual method for the remaining vehicles. Do not write "check the machine and continue"; write who may reset the unit and what has to be recorded before it runs again.
Put the escalation ladder on the same sheet as the log so it does not have to be recalled at three in the morning: site contact for a utility problem, supplier contact for a machine fault, customer contact for a held vehicle. Name the people with their numbers, and note the response time the supplier has committed to in writing. Spares and service response are quotation line items; if they were never quoted, the ladder will not be honoured when the fault happens.
Records, acceptance, and the questions to send the supplier
Document a trial like a live shift, because acceptance is measured against it. Run one shift with the intended machine, record it with the same log fields, and file the trial record with the utility survey. Acceptance wording then becomes concrete: the provider meets the level of work demonstrated in that record, on the vehicle groups named in the scope table, with the utilities surveyed at that site.
Before signing a purchase or a rental, send the supplier one written list of open points and require written answers: supply per hour, running time on a full tank and on a single fill, hose and wand reach, weight and whether a lift or two people are needed to move the unit, noise, the cleaning agents the supplier approves, spares availability and fault response time, and whether the published duty list covers the vehicle groups in the scope table. Keep unanswered items out of the method statement until they arrive.
Keep the records for the period the contract names, in one place, with the machine serial number attached to each shift. When a complaint arrives weeks later, the answer is a log line, a photo, three names and the survey that showed the drain and the power point were adequate on the day the work was done. That is the difference between a claim and a closed file.
Scope note: the product page for the Fixed Steam Cleaning Machine PowerDe HW02 lists vehicle exterior cleaning at gas stations and parking lots, interior vacuuming and disinfection, and engine-compartment cleaning, with the figures quoted above. Vehicle groups and depot scenarios beyond those published duties come from the customer keyword and application brief; confirm the machine's suitability with the equipment supplier, and surface and component limits with the vehicle maker, before writing either into a site procedure. Fields the specification does not publish, including supply per hour, running time and drying time, must be measured on the provider's own fleet during the trial or obtained from the supplier in writing.
