serious accident at the track

[doo540]

Saturday night I visited a newly open rc track near my town. 9000 square foot , inside off road dirt track. I went on electric night of course to see what the truggy class looked liked. Top notch operation, very well laid out operation with all the new high tech stuff. There was a kid there that drove with his mom 2.5 hours one way just to race. My son, some friends and myself were having a great time watching the action. I was just commenting to my friend how one of the 1/8 scale buggies looked to be driving a little out of control, you know over shooting corners and running into stuff at a high rate of speed.
When the next thing we know one of the corner marshalls was down on the ground. I didn't personally see it happen but one of the 1/8 buggies jumped the table top section, left the track area and hit the marshall in the side of the head. Knocked the "kid" 18-19 year old right down. The owner of the track stopped the race and raced over to the kid and very quickly took control of the situation, they called 911 as soon as it happened. Knocked the poor kid for a loop, he couldn't remember his name,were he was or what he was doing 10 seconds earlier.

I decided it was time to leave shortly after that. What precautions do other tracks take to help deal with this sort of thing? The marshall was standing in his correct area, but maybe was looking the other way when the buggy hit him? Do people wear helmets when they are in the middle of the track marshaling?
