On the new ESA50 (4/15) form on Question 1 there are only 4 option boxes to tick regarding how far you can mobilise. The lowest is 50meters - what do you do on this question if you cannot mobilise even 20 meters without assistance from someone?
In previous versions you could tick the descriptor box which said 'less than 50m ' but they have changed this question so you can no longer check an appropriate box.
