What this is
What is a mobile plant defect report?
What is a mobile plant defect report?
It is a record raised the moment a fault is found on mobile equipment such as a forklift, pallet truck or access platform, at any point in its operating life, not only at the scheduled pre-use check. It captures what the defect is, how severe it is, what immediate action was taken, and the repair that closes it out.
How is this different from the powered truck daily check?
The daily check is scheduled and routine, run at the same point every shift on every truck. This report is unscheduled: it exists because a fault can appear at any time, and a shift's worth of exposure between discovery and the next daily check is exactly the gap this record is designed to close.
Who raises the report?
Whoever finds the defect, most often the operator using the equipment at the time, but also a technician during a service or another operator on handover. Raising it does not require certainty about the cause, only an accurate description of what was observed and whether it affects safety.
Scope
When is a mobile plant defect report required?
This record is one step in a larger programme, and it exists for one situation: a defect found on mobile equipment outside the scheduled daily check. Using it for the daily check itself, or for something that is not a defect, produces a record that does not fit its own fields.
Use this template when
- A fault is found on a forklift or other mobile equipment at any point other than the pre-use check
- A defect is discovered during handover, a service, or an unrelated inspection
- The workspace is being set up and the register needs a defect-reporting entry established
- A linked record needs this one to exist: powered truck daily check, work orders, asset register
Do not use it for
- Powered Truck Daily Check, which checks a forklift before each shift and is where a defect found at start-up should be recorded first.
- Forklift Battery and Charging Check, which checks charging area ventilation, electrolyte handling, connectors, eyewash and no ignition sources, not a mechanical defect.
- Attachment Use Authorisation, which authorises use of a specific attachment on a specific truck, with the derated capacity stated, rather than reporting a fault.
- Work order, which is where the repair itself is scheduled and tracked once this report has raised it and severity has been established.
- Anything outside KnowFleet, which belongs in the workspace that owns that process.
Compliance mapping
Which ISO 45001 cl.8.1 requirements does this satisfy?
The duty behind this record is the same one behind the daily check: an unsafe truck must not be used. What differs is timing, and regulation is largely silent on defects found outside a scheduled inspection, so the report's structure exists to get from discovery to a controlled, quarantined machine as fast as the daily check gets to a fit-for-use decision.
| Clause | Requirement | Where it lands |
|---|---|---|
| OSHA 29 CFR 1910.178(q)(7) | A truck found not in safe operating condition is removed from service immediately, at whatever point that is discovered, and stays out of service until restored to safe condition | Immediate action |
| ISO 45001 cl.8.1.2 | Hazards are eliminated or risk reduced following the hierarchy of controls; for a defective machine this means physical removal from availability, not a documented warning | Immediate action |
| ANSI/ITSDF B56.1 | A defect affecting safe operation, however discovered, is reported without delay rather than held until the next scheduled inspection | Header |
| PUWER 1998 reg.5 | Work equipment is maintained in an efficient state, in efficient working order and in good repair, with maintenance logs kept up to date where appropriate | Repair |
| ISO 45001 cl.8.1.1 | Operational controls are maintained as planned, including repair carried out by a competent person and verification before the machine returns to use | Repair |
| ISO 45001 cl.9.1.1 | Monitoring and measurement of trends, including repeat failures on the same asset, feeds into whether a control such as a maintenance interval remains effective | Outcome |
| ISO 45001 cl.5.4 | Workers participate in operational activities affecting their own health and safety, evidenced here by immediate reporting rather than continued use | Header |
What it does not cover
- Powered Truck Daily Check, which is the scheduled pre-use inspection and is where a defect found at the start of a shift should be recorded, with this report used for anything found afterwards.
- Forklift Battery and Charging Check, which addresses the charging area rather than a mechanical or safety defect on the truck itself.
- Attachment Use Authorisation, which is the approval record for a specific attachment on a specific truck, not the route for reporting a fault with it.
- The work order, which schedules and tracks the repair labour once this report has established severity and raised the requirement.
- A statutory thorough examination, which is a periodic competent-person inspection under lifting-equipment law and is not satisfied by an ad hoc defect report, however thorough.
Global
Mobile Plant Defect Report requirements by country
The obligation to stop using unsafe equipment does not depend on when the defect was found; what differs is how explicitly ad hoc discovery is addressed.
OSHA 29 CFR 1910.178(q)(7)
A truck not in safe operating condition is removed from service until restored, regardless of when or how the defect was discovered.
The duty attaches to the condition of the truck, not to the inspection schedule, so a defect found mid-shift carries the same removal obligation as one found at the pre-use check.
PUWER 1998 regs.5 and 6
Equipment is maintained in efficient working order, and inspection at suitable intervals must detect and remedy deterioration; a defect found between scheduled inspections still triggers the maintenance duty.
A site cannot treat a defect found off-schedule as informal simply because it fell outside the routine check; the maintenance obligation is continuous.
ISO 45001 cl.8.1.1 and cl.8.1.2
Operational controls, including maintenance and repair, are maintained as planned, with hazards eliminated or risk reduced through the hierarchy of controls.
Certification auditors examine the time between discovery and quarantine as closely as the repair record itself, since that gap is where the actual exposure sits.
How to complete it
How to complete a mobile plant defect report, step by step
The form walks from discovery to return to service in order; what decides defensibility is whether that order was actually followed, not back-filled once repair was done.
'Out Of Service Tag Applied' and 'Key Removed And Controlled' need to correspond to something that actually happened, not a form answered from the office afterwards. A report completed without the tag on the truck and the key accounted for has recorded an intention, not a control.
The severity questions ask about safety, load handling, braking, visibility and how quickly the fault could worsen. A hairline crack that has not yet failed still needs to be rated on what happens if it does, under load, mid-lift, rather than on the fact that nothing has gone wrong so far.
These two fields exist because the same fault recurring on one truck usually points to the interval, not the operator, being wrong. Answering 'No' to interval review reflexively, without checking the unit's history, defeats the reason the field is there.
This field is easy to skip because the repair record closes without it. But an operator who does not know a truck was cleared will keep the same caution as before, or worse, assume a related fault was never addressed.
What auditors find
Most common mobile plant defect report findings
Findings concentrate at the discovery-to-quarantine boundary; the report itself is usually accurate, the question is whether the machine matched it.
| Finding | Clause | What fixes it |
|---|---|---|
| Equipment marked stopped but the key was not removed or controlled. | OSHA 29 CFR 1910.178(q)(7) | Treat key control as the actual quarantine control; a stopped truck with the key available is not quarantined. |
| Severity rated low on a fault that later proved to affect braking or steering. | ISO 45001 cl.8.1.2 | Rate severity on worst credible outcome under load, not on the observed state at the moment of discovery. |
| Truck returned to service without 'Function Tested After Repair' being answered. | PUWER 1998 reg.5 | Block return-to-service authorisation until the post-repair function test is recorded. |
| Repeat defect on the same asset with 'Maintenance Interval Review Needed' answered No each time. | ISO 45001 cl.9.1.1 | Flag a third occurrence on one asset automatically and route it to a maintenance-interval review regardless of the field's answer. |
| Report raised well after the defect was discovered, evidenced by a gap against the daily check or work order timestamps. | ANSI/ITSDF B56.1 | Raise the report at the point of discovery; a delayed report has left the truck in unknown status for the intervening period. |
| Repair carried out and parts used but competence of the repairer not recorded. | ISO 45001 cl.8.1.1 | Name the repairer against a competence record before 'Repaired By Competent Person' is answered Yes. |
Case in point
Case in point: the tag that came off with the shift
An operator found a hydraulic leak on a reach truck mid-shift, stopped using it, and raised a defect report rating the fault as affecting load handling but not an immediate danger. He applied an out-of-service tag, but the site had no procedure for controlling the key separately, so he left it in the ignition, as was normal practice, and went to get a replacement truck.
The next shift's supervisor, short-staffed, saw a tag he assumed was a routine service reminder, removed it without checking the defect report, and put the truck back into use as the only reach truck free. The leak worsened under load two hours later, and the truck lost hydraulic pressure mid-lift, dropping a pallet from height with no one beneath it by chance. The report had rated severity correctly and been raised promptly; what failed was that quarantine depended entirely on a paper tag carrying no information about why it was there or who to check with.

From a document you fill in to a programme that runs itself
The report itself is rarely the weak point; what fails is the physical gap between a defect logged and a machine actually staying out of use until fixed.
Holds the defect report against the asset it names, links it back to the daily check and work order, and tracks out-of-service defects as a fleet-level trend.
Carries the repair through from work order to function test and return-to-service authorisation, so a quarantined truck cannot re-enter use without that chain being complete.
Flags a repeat defect pattern that points toward operator handling rather than the machine, and routes it to a competence check instead of another repair.
Watches for a defect marked stopped without a matching tag and key-control status, and raises the gap rather than waiting for the next shift to find the truck back in use.

Mobile Plant Defect Report definitions and key terms
- Quarantine
- Physically removing equipment from availability, through a tag and controlled key, so it cannot be used before the defect is repaired and function tested.
- Out of service tag
- A physical marker attached to defective equipment signalling it must not be used; effective only when paired with key control, since a tag alone does not stop use.
- Immediate danger
- A defect condition where continued use presents a risk of harm without further deterioration being needed, requiring the equipment to be stopped without delay.
- Return to service
- The formal authorisation, after repair and function testing, that equipment may be used again; distinct from the repair being physically finished.
- Repeat defect
- The same or a closely related fault recurring on one specific asset, which usually indicates a root cause the repair addressed the symptom of rather than the cause.
FAQ
Frequently asked questions about mobile plant defect report
Should a defect found during the daily check use this template instead?+
No. A defect found at the pre-use check is recorded on the daily check itself, which links to this report if the defect is significant enough to need its own record. This template is for a fault found at any other point.
What does 'low is good' mean for this template's score?+
The metric tracked is out-of-service defects, so a low count is the target, unlike most checklists here where a high pass rate is good. A rising count is a maintenance or fleet-condition signal, not evidence the reporting process is failing.
Is quarantine required for every defect?+
Only where the defect affects safety, load handling, braking, steering or visibility, or could worsen quickly. A minor cosmetic fault does not need the truck stopped, but the severity questions have to be answered honestly to reach that conclusion rather than assumed.
Who authorises return to service?+
Whoever is named against 'Return To Service Authorised', typically engineering or a maintenance lead, after the repair is complete, function tested, and the operator has been informed. It should not be the person who did the repair signing off their own work as safe.
What happens if the same truck keeps failing the same way?+
The record asks directly whether the maintenance interval needs review. A repeat defect is more often a sign the interval or repair method is wrong than operator misuse, and treating each occurrence as isolated misses that.
Can the template be changed?+
Yes. Every field, option, score and conditional rule is editable, and the links to the daily check, work orders and asset register come with it. Most sites install it as it is, run it for a cycle, then adjust.
