Pre-shift check with six defects and no spare truck
At 06:50 you begin the pre-shift check on a 3.0 t diesel counterbalance truck with 4,200 hours. You find: a 40 mm chunk missing from the right front tyre with cord visible; the horn sounds only when the steering wheel is at certain angles; the seat belt has a 30% frayed section; the data plate is missing; one mast chain has about 15 mm more slack than the other; a coolant puddle under the radiator; and the engine oil is at the low mark. The first delivery truck is at the dock and the dispatch supervisor wants the forklift on the floor in 10 minutes. The site has no spare forklift.
1. Sort the findings into out-of-service defects and items that could be repaired or monitored, then state your decision and the reasoning behind it.

Out of service:
- Tyre with cord visible: the tyre is structurally damaged and can fail under load; a blowout on a counterbalance truck with a raised load is a tip-over risk.
- Intermittent horn: it is a warning device, and 'sometimes' means it cannot be relied on when a pedestrian steps out.
- Missing data plate: without it I cannot verify the truck's rated capacity or confirm it matches the attachment and configuration. Capacity is not guesswork.
- Uneven mast chain slack: 15 mm difference suggests wear, stretching or a seized sheave; the mast can bind or drop unevenly.
- Coolant leak: overheating, loss of coolant onto the floor, and possible engine damage; not a 'watch it' item at the start of a shift.
Repair or monitor: engine oil at the low mark is a top-up item, and the frayed seat belt at 30% is a restraint defect that must be replaced, not monitored.
The decision is to tag the truck out of service. The combination matters: even one of the first four defects is enough to stop the truck.
2. What would you write on the tag, and what would you say to the dispatch supervisor?

The tag should be attached where the next operator will see it, ideally on the steering wheel or ignition, and should state: date and time, truck number, hour meter reading, my name, a clear 'DO NOT OPERATE - OUT OF SERVICE', and the specific defects: damaged right front tyre with cord exposed, intermittent horn, missing data plate, uneven mast chain slack, coolant leak, frayed seat belt, oil low. I would also note that the key has been removed or the truck isolated, and who has been notified.
To the dispatch supervisor I would give the facts and the consequence, not an opinion: 'This truck cannot go out. The tyre is down to the cords, the horn only works at some steering angles, the data plate is gone so we cannot confirm capacity, and the mast chains are uneven. If it fails with a load up, someone gets hurt.' Then I would offer options: borrow a truck from another site, call the rental company, or use a pallet truck for loads that are suitable and within its rating. I would log the defect and the notification in the handover book.
3. The supervisor says: 'Just unload this one truck, it is only 20 minutes.' Explain your response, including the safety and policy basis.

I would decline and explain why 'only 20 minutes' does not reduce the hazard. The tyre, horn, data plate and mast chains are all used in those 20 minutes; the truck does not become safer because the job is short. In fact a rushed unloading job at a dock is one of the higher-risk moments, with pedestrians, trailer edges and a raised load.
The basis is both company policy and the general pre-shift inspection rule: a truck found with a condition that affects safe operation must be removed from service until it is repaired. Many sites also require a documented daily inspection and a tag-out record. I would not argue the regulation clause by clause on the floor; I would state the site rule, show the tag, and escalate to the shift manager if the instruction is repeated. If the delivery is urgent, the supervisor can arrange a replacement truck or a different unloading method. I would record the exchange, because a pattern of pressure to use defective equipment is itself a safety issue.
