The pilot of a light aircraft recently landed at an airfield. Having parked and disembarked he walked to the airfield control tower some 75m away. As he was doing so he was told that he should be wearing a high-visibility vest. On hearing this he contacted the airfield manager who was, apparently, unaware of the policy but suspected it was the result of the CAA inspector.
HSE was consulted on guidance produced by CAA which recognises that the wearing of high visibility vests is a sensible risk control measure to be taken when airside. Airside pedestrians need to be visible to drivers of refuelling vehicles and the like. The requirement to wear high visibility vest is reasonable and likely to be common practice at airfields.
