Snatch straps are a problem on several levels:
Firstly, they are marketed as a cheap recovery aid that will get any fool out of a bog. There are no warnings or instructions on the pack.
Secondly, it is promoted that the stronger the strap, the better it is. I'd suggest that the stronger straps are more lethal.
Thirdly, the technique.
The idea of attaching a strong elastic strap between two vehicles weighing 2-3 tonnes each is very much reliant on the strength of the recovery points. Trouble starts when the recovery points can shear off and become a lethal missile.
Recovery points on vehicles were never designed for snatch recovery. Many are tie downpoints for transport while the stronger ones are described by manufacturers as "tow points" - for towing, not snatching. Ask any manufacturer, and they will tell you their points are not rated for snatch recovery. So when you do a heavy snatch and the recovery point breaks, and recovery point and shackle go flying thru the air at a million kms per hour, they will be aimed directly at the other vehicle or any onlookers.
So how can snatching be made safer?
#1 Don't snatch if a simple tow will suffice.
#2 Clear sand or mud from around the wheels/chassis to make the recovery easier.
#3 Be certain of the strength of the points you are using. Aftermarket hooks are strong and are rated - but they are only as strong as the bolts holding them on, and the metal to which they are bolted to. They need to be chassis mounted for strength. We could have a huge discuss on recovery points and what is suitable.
#4 Don't use bow shackles unless absolutely necessary - it can be a big missile.
#5 Use a bridle for attaching the strap to the front of the vehicle. Its a simple strap that attaches to two recovery points on the front of the vehicle - it halves the load on the front recovery points, distributes the load, and if a recovery point were to break, it would be retained by the other side.
#6 Air brakes are often taught, but are totally useless.
Whenever I write this blurb, I always ask why do I bother. Its a hell of a lot simpler to suggest to people to tow or winch.......but I have to admit, the simplicity of a gentle snatch is often the simplest most effective way to recover - just a pity that it can also be the most dangerous.

Phil,
Isnt a snatch strap a thin G string??? LOL!!!!
On the serious side...
Well said, all valid points, and all so true for safety, but how far do we need to go to educate the idiots?
My rifle doesnt have 'use this end' on it!
Are we going to end up a society like America, where we put warnings on everything to prevent law suits?
Arent the supposed users old enough to know that its not good to play with a toaster in the bath?
Ok I joke, but seriously people need to start accepting responsibility for their own actions, without trying to blame manufacturers for not putting idiots guides on everything.
Guess we all need to stock up on snatch straps before they ban them, .. but wait,... they will ban 4x4 aswell if they get their way.
Did you see that accident this afternoon.... MY GOD.... ANOTHER STATION WAGON!!! you dont hear that do you...
nuff said,
Rgds

Good one Phil & Ron. There are two problems as you point out, 1; the tecnique and 2; the attachments.
The first problem should be easy to fix - education.
The second is a hard one because it involves money! It is very strange but a lot of people spend mega bucks on their vehicles tyres, sound systems, lights, fuel tanks, shocks etc. but will not spend any money on getting properly engineered tow hooks fitted! For a couple of hundred dollars MAX! most of the potential danger could be downgraded to almost zilch.
Also, unfortunately you also see people making coments on this
forum like ;
"I have done hundreds of snatch recoveries useing shackles attached to those little welded tie down points on my vehicle for years and have never had a problem, so there - you don't know what you are talking about"
As soon as you see coments like the above - run a mile from any other pearls of wisdom from that person !

Ron,
I like your posts - good stuff.
Kiwi,
The fix on both counts is Education.
But when you consider how many snatch straps are sold, and at the club we spend a few hours in the sand teaching people how to use them, and what to use and what not to use for recovery points, it strikes me that Education is the big expense.
I reckon it won't be long before a coroner gets hold of this stuff, and maybe some warnings will get put on the straps.
Cheers

Ron, the rot has set in I'm afraid. Ruger have a paragraph long, stamped warning on the barrel of their handguns these days with words to that effect. (they're still good though:-))
Perhaps common sense should be renamed 'rare and unusual sense'?
