Trouble is wheel guarding is anything apparently anything but "common sense" True guarding would prevent any chance of being able to touch a wheel while it is moving. Sort of like an OSHA approved coupling guard. The guarding you need for protecting the wheel is a lot different than what you will need for when the wheel shatters.
Common sense would tell you to keep the pit area clear of any non essential people especially visitors. Guarding in the pits should include any mechanism capable of sudden movement, pinch points, etc. I think this would impact the overall goal of First if we went fully down this road.
I am not really arguing the need to properly guard rotating components. I do think there needs to be more published guidance from First & not left up the event's lead inspectors discretion.
PS I think this needs intelligent discussion without the need for flame suits.
