The costs need to be grossly disproportionate, not just greater than.>>

Hi Paul

I've given it some thought and updated the sentence to this, which I think 
reads better.

"Put simply, ALARP means the risk is Tolerable if the costs of the risk 
reduction are much greater than value of the risk reduction."

I'm looking to explain the ALARP concept in easy to understand terms, and in 
the context of how VALID goes about dealing with it for tree risk-benefit 
assessment and management.  When the risk is amber, ALARP decision-making, 
and what's grossly disproportionate or not, is built into the App around 
which way the Likelihood of Failure is heading (attached).  So, the assessor 
or duty holder is spared the numberwang of disproportion factors and complex 
cost benefit analysis.

Cheers

Acer ventura
