RoSPA / IAM terminology.

In my previous thread I posed the question what does P.O.W.D.E.R stand for and Metalist wa 99% correct. PETROL, OILS,WATER, DRIVE/DAMAGE, ELECTRICS, RUBBER.
So powder is for the bike, well how fit is the rider to take it out on the road?
‘I’M SAFE’ is an acronymn. What does it stand for?
