something to think about re. tracked chippers

[Tucky]

The concrete cutting ones are even more powerful. The ones on ships replace the old fashioned sand blasting rigs as aparently there not allowed to dump the grit overboard for enviromental reasons.

We had a 750bar machine in a paper mill i worked in, we had to wear special kevlar suits and boots and have a course by the water jetting association.

The intresting thing is injurys from these are treated as 'injection injurys'.

The two main problems are the dirt which gets dragged into the tissue along with the water, this often means the surgeon has to 'butterfly' the wound to clean it. The second is have the jet collects tissue in the same way a bullet does, in short it makes a mess.
