ok heres my scenario, i have a van mount wfp but i do a flat above some shops. on a town centre cross roads with traffic lights. so i cant park close enough to use the van mount. luckily i also have a trolley so i could use that.
my problem is i then pour water all over the shops below to clean the flat windows and also cause a lot of water falling above entrances to the shop soaking customers of the shop and causing water to be trailed into the shops below.
so for me the safest practicable option is to ladder the job using safety precautions.
and a lady with her 4 year walks out of the shop, she is trying to control the child and dosn't see the ladder.
She crashes into the ladder and the ladder falls, the cleaner falls and lands on the child breaking his back in the process.
The child, who saved the cleaners life because he had a softer landing, dies from severe head injuries.
Will the hse accept your risk assement that the use of a ladder was correct in this case??
