Chris, maybe it's time to drop the take the machine off the van on every job image. I've never done that. Ours on the van is mounted side door and 50m hose. Less arsing about. What would you do on a brick cleaning job for a principle contractor? Van mounted reflects well on RAMS too. In our RAMS it states 'refuelling of machinery occurs on board of vehicle due to van mounted system'. Also 'Manual handling is kept to a minimum with pressure washing system as it is van mounted therefore does not need to be lifted on and off the vehicle'.
Most of my work is domestic or inaccessible places.An example
http://cleaning-service.uk.com/lune-aquaduct-lancaster/ It is very important to me to be flexible and mobile.The machines we use are light weight (75kgs) and i have fold up wheel chair ramps in all of the vans.
With regards to refueling we use plant nappies if required, again these are light weight and easily moved.
With regards to health and safety i appreciate there is a need for it ..i worked on nuclear power plants for years . But sometimes it gets out of hand and whatever method you submit somebody would disagree with.
As an example: Refueling in a confined space... a van . To me this is fraught with danger, storage of fuel next to a hot machine,danger from fumes,danger from slip hazards ,escape in the event of a fire ..etc.
I am not saying it is the wrong way to do it ,it seems perfectly safe from your point of view hence that is why you use this method. I just used it as an example of how people perceive danger. One mans danger is another mans fun...I kitesurf, race enduro bikes and smoke crack !!
Regarding example " What would you do on a brick cleaning job for a principle contractor "
This is what i would be thinking.
I am the professional...thats why they have hired me to do the job. Hence they should listen to me .This is what i require from them to make the job easy and this is how i propose to do it.
