You can't eliminate risk completely, it's more of a risk crossing a busy road than it is window cleaning with a stick
When crossing a busy road you use your common sense to reduce the risk, you don't cordon it off, gave a spotter or put on your hi viz .
This kind of over the top health and safety culture is what stifles all of our emergency services making them less effective and stifles business growth .
It needs toning down and some common sense thinking applied .
