That's a fair point.
Example. Scaffolding erected, Portaloos on every floor, risks assessed (or so we thought)!
Lazy prat can't be bothered to walk for a few minutes to relieve himself in appropriate place. Climbs over handrail to do his business and falls breaking a leg. Tries to sue saying he wasn't given risk assessment or told of the risk of urinating while hanging on to the outside of a scaffold.
Some people will always find a way to ruin it for everyone else.
