I never practise aerial rescue, although I do do the AR event in the ISA climbing comps, so I guess that might count.
No specific rescue kit here.
Depends on the scenario really, if I'm out on the tips or on spikes on a pole there is really very little chance of a rescue in a realistic time frame.
5 day first aid, now expired. Probably get around to a refresher this year sometime, but I will only do the shortest possible course.
Very rarely have a separate access/rescue line. Tbh dont do many big trees these days, on a big tree I would have a footlock/srt line, but dont often have a rescuer that could use it anyway.
To put all of this into context, I mainly subbie climb, so work with a variety of tree teams. I dont usually work with another climber, usually have another CS38 on site, but probably have never seen them climb, let alone practised a rescue with them. You cant be confident in someone's ability to rescue, even if you know they can climb, under those circumstances.
The overriding lesson for me in all this is, if you get hurt, get yourself down immediately. There is a little window of opportunity following most injuries where you can get to the ground yourself on an adrenaline surge. Obviously this is dependant on being prepared to make an emergency descent at all times, so rope clear below you, no tangles and knots etc. On a pole, I either set my ropeguide or choke off the climbing line and back up my hitch with a descender.
The only time you wont be able to get down yourself is unconsciousness, or if trapped by a cut section. Proper planning of the work is essential to minimise risk.
While you are researching, see if you can find an answer to this question, how many lives have been saved by aerial rescue?
Although it is a laudable cause, I personnally believe too much emphasis is put on rescue, and not enough on proper work planning and always being ready to get yourself down. That may be controversial, but I believe my reasons are sound.
Firstly, no-one can ever rescue you quicker than you can get down. Even with the best rescue set up and rescuer in the world, you are looking at 3-6 minutes minimum, from whistle to touchdown. I can get out of any tree in less than a minute, usually less than 30 seconds. Once you are on the ground, then proper first aid etc can get under way. Also, on a noisy work site, it could be a little while before anyone on the ground realises your in trouble. If you come burning out of the tree dripping blood, its pretty obvious.
Secondly, most tree teams dont have a really good AR set up, or rescuer, and it could easily be 15-20 minutes before touchdown. Stop work, get the kit out of the truck, set it all up, remember how to tie a blakes, get the ladders.......
Thirdly, no matter how practised or skilled, you cant predict how your team will react in an emergency. More practise helps, as the routine that is drilled into you will just take over, but most teams that dont practise that often will be panicking a little until a plan is formed.
As for applying first aid in the tree, how long does it take you to reach around for your first aid kit, remove a dressing, unwrap it without dropping it, and apply it? I'll wager I could be on the ground before you have unzipped the pouch.........
Apologies for the long post.
