    This injury was caused by an exploding cell phone, according to the Brazillians on my rig.
    One of them showed me the footage at the hospital only, with Portuguese commentary, explaining the dangers of charging phones.
    It goes on to say that the man died of shock.
    It does seem unbelievable that a cell phone can do this.

    At the end of the video (the 4x4 chain breaking video), the woman at the hospital is speaking in Portuguese, and it sounds like a Brazillian dialect.
    I can't access YouTube from here, perhaps somebody could search for "exploding cell Phone injury " , see what shows up.

    I can't really comment on the above statement there are just too many unknowns. However, I found numerous websites with titles like "worst cell phone explosions" and that guy is not among them. All cell explosions had burn marks. I find the cell phone thing a bit hard to believe.

    I also found the youtube video. The title of the video explains that the chain broke and the driver unfortunately died. I will replace the video link with the youtube link.

    The questions remain the same: why was proper techniques not followed? Why was the bonnet not open? It could have stopped the chain.

    The guy in hospital is very clean for a guy that have been mudding.

    I have seen what damage the snatch rope alone did to my Jeep on the rear corner where it is tripple plated and I have seen pics of a shackle going into the no 1 cilinder. Being in the motor repair business, I know how weak a bonnet is.

    No need to call Mythbusters, just listen to guys with experience.

    The chain would have been safe it it was used for pulling and not snatching...

    If the bonnet is open, I seriously doubt that anything will go through it. Remember a bonnet is not solid, so anything flying in the direction of the bonnet will lose most of its energy as it hits the bonnet till it pushes it all the way back onto the win screen. Then it still has to have enough energy to go through the bonnet pulling a chain and strap and then go thorough the windscreen and hit the person. If it could do all of this the injuries would not be those as shown in the video.

    Those injuries are from a gunshot.

    Agree, but I would not make it a general rule.

    The reason a say 'not a general rule'.

    If you can get enough energy in a chain will still back lash when it breaks, as steel is still elastic, but not as much as a rope. But yes in just pulling its much less force than snatching. Its just basically the vehicles weight and the grip factor of the tyres. In mud the grip factor can be as low as 10 %, or even less, but on a hard surface it can never be more that the weight of the pulling vehicle.
    In snatching the force is a few time more that just pulling, as the motion energy is also transferred. So can get away with a much lighter chain when just pulling with a light vehicle.
    Snatching with a chain is out anyway. If the chain don't break something else will breaks most likely, because the energy is transferred too quickly. With a snatch rope it is a more gradual process and some more energy is also lost in the rope through the elongation process. In a chain the elongation is only a few mm's if that much, and not much energy is lost in the chain itself either, as about all energy is transferred. And if the chain snaps the elongation will revert back and cause a back lash.

    I am very anti snatch. Have seen a recovery point on a Ratel being teared out of 20mm armoured steel. My experience with snatch ropes and 4x4`s in mud is not good. When we ruined my snatch rope a year or so ago during a serious mud recovery I have decided not to replace it.

    I knew how good my 4x4`s recovery points are. Not even the recovery point but even off road bumper mounts that is not to spec can fail during recoveries. Many off road bumpers use the same mounting point as standard bumpers and I sometimes wonder how much care is take during installation with bolt spec`s and additional support and brackets.

    Even professional recoveries can go wrong when equipment fails.

    Now my question how sure are you Mr 4x4 that your recovery points and bumper attachments can handle the forces of snatch recoveries ?

    Not all replacement bumpers are equal!

    That is my point in an earlier post. Recovery hooks, points are only as good as the way they are installed. The very reason I am not fond of snatch rope recoveries. How sure are you that your aftermarket bumper or the recovery vehicle`s point of attachment is up to standard. Many aftermarket bumpers are bolt onto the same attachments as the OEM bumper without additional support or brackets.
