Yes, the Health and Safety in this country is mad. Rules are here to be followed with blind obendience, and with utter disregard to initiative or outcome: as long as they are followed that's the only thing.

Having said that, to play devil's advocate, what happens if these two either tried themselves or let others enter the building? I imagine they would be responsible for any injuries that occur.

How bad was the fire when this occurred? Would the people - with no equipment - have possibly got inside to get the persons, only to have their shoes / clothes melt and burn, killing them and those they are trying to save?

It is always easier to criticize inaction and bemoan the 3 deaths thus caused, and not be aware of the 5 deaths caused by semi-mindless bravery.
