Refuelling and Parking on a Sloping Site at End of Shift
It is the end of a 10-hour shift. Your 360° excavator is low on fuel and parked on a 1-in-10 slope on a compacted site compound, with the bucket grounded and the dozer blade down. The site fuel bowser is a static tank with a hand pump and a drip tray, 30 m away on level ground. The weather is dry but the light is fading. The machine is due to be transported off site at 07:00 the next morning on a low-loader. The transport driver has asked you to leave the machine 'ready to load' - meaning tracks clean, bucket off, and parked close to the ramp. The compound has a site speed limit of 10 mph and a pedestrian walkway along one edge.
1. Plan the shutdown and refuelling sequence for the end of shift, including the order of operations and the reasons for each.

Order of operations:
- Park on level ground if possible - 1-in-10 is not ideal for refuelling or for leaving a machine overnight. Move the machine to the level part of the compound before refuelling; if it must stay on the slope, chock the tracks and keep the bucket and blade grounded.
- Shut down and cool - switch off, allow the machine to cool before refuelling (hot exhaust/hydraulics and fuel vapour).
- Refuel at the static tank - engine off, no smoking, no naked flames, bonding/earthing as per the site procedure, drip tray in place, absorbent kit available, spill kit nearby. Do not overfill; leave expansion space. Clean up any drips.
- Record the fuel taken and any spill.
- Return to the parking position - if the machine was moved to refuel, return it to a safe, level, well-lit parking spot, not necessarily 'close to the ramp'.
- Shutdown - bucket and blade grounded, controls neutral, parking brake on, key removed, cab locked, windows closed, machine tagged as per site procedure.
- Walk-round - check for leaks, damage, and that the machine is secure; note any defects for the morning.
Reasoning: Refuelling on a slope risks spillage and roll-away; a hot machine is a fire risk; the shutdown sequence (grounded bucket/blade, brake, key out) is what prevents unauthorised movement overnight.
2. The transport driver wants the machine left 'ready to load' close to the ramp, with the bucket off. How do you respond, and what are the constraints?

Respond: I can prepare the machine, but I will not compromise the safe parking and shutdown requirements to do it. 'Ready to load' does not override the shutdown procedure.
Constraints and actions:
- Bucket removal - only if the quick-hitch is the correct type, the bucket is supported on firm level ground, the machine is on level ground, and the removal is done to the manufacturer's procedure with the area controlled. A bucket dropped on a slope is a crush hazard. If it cannot be done safely in the fading light, it waits until morning.
- Position near the ramp - the machine can be parked on level ground near the ramp, but not on the slope, not blocking the pedestrian walkway, and not within the 10 mph traffic route without segregation.
- Lighting - fading light is a constraint; if the preparation cannot be done safely, stop and complete it in daylight.
- Communication - tell the driver what has been done and what remains, and record it (handover note). The driver must not move or alter the machine's parking state.
- Transport itself - loading is a separate planned operation with its own controls (ramp angle, restraints, exclusion zone, banksman); it is not something to improvise at 07:00.
Why: The driver's convenience is not a reason to leave a machine on a slope, unsecured, or with a bucket removed in poor light. The safe handover is the priority.
