which would occur 1/1,000 per annum
the acceptable range,
is tolerable for a specific slope
while existing slopes

need to be in the ALARP. Possibility of
1v:1h - risk neutral
▪ High tolerance means 10,000 fatalities
not allowed at all
less budget for

mitigation actions and

vice versa.

▪ Applicable nationwide
