Having worked on the railway, London underground and the Channel Tunnel construction, I know a bit about Health and Safety in dangerous environments. In my experience Councils don't, they know about paper.
The regulations are simple and risk management based and impose a duty of care on BOTH employer and employee to behave responsible and respectively provide and use NECESSARY safety personal protective equipment.
Contrary to the view held by many councils risk management doesn't imply the elimination of risk, merely a sensible attitude to minimising it.
The risk at Glenforsa is the same as any other grass strip i.e. small and the number of things to pay attention to are few, since the responsibility for its safe use rests with the pilot not the operator. All the operator has to do is answer questions from pilots honestly and know the length and condition of the strip, if they can observe the weather that's a help too.
