So far as is reasonably practicable springs to mind.
If the cost of making an improvement in regard to time, trouble and money is higher than the benefits of preserving lives and machinery then sod all will happen and that is the case here.
It's a sad world where money is more important than peoples lives. Just look at the politics round about you, recent events clearly demonstrate this fact.
My condolences go out to all those affected by this and other similar events.
I do my best to preserve life, corporations do their best to make money.
