Couldnt it be done by parking your van down the road?
Ive got 100m of hose so can reach most places
Just a thought....
Just by having 100 metre of hose does not subtract away from the potential hazards and risks associated with trailing hoses.
Irrespective of signs, these are not fail safes that will prevent accidents. You are required to cordon off the area, otherwise you can easily find yourself with a tripping liability. Better ask your insurance company if they will fully cover this type of neglect to cover any claim 100% or will be asking you for "some" of the money in any attempt of a claim - believe me if they can get out of paying a claim, they will.
The "no win no fee" claims will be finding their way onto window cleaners who trail hoses about.. it only takes some savvy joe public to work this out.. and have a "trip" and injure their necks/back etc..
So yes the only way you can really do it is by a trolley/backpack or trad.
