I think there is some thing about bare, unprotected hydraulic hoses within x cm distance of a operator, hence the use of burst sleeves, covered in, or remotely controlled valves on CE marked machinery. And agree with you out the injury's caused I know someone who nearly lost his thumb from a pin hole leak on a hose.

Hydraulic injection injury - glad you mentioned that ("glad" is not really the right word though)

 

What are your thoughts on protective over sheaths for hyd hoses? I can see the potential benefit on the one hand, protection from UV, abrasion etc and some dissipation of a jet after hose failure, but on the other hand, possibly a tendency to "hide" a visual clue to a hose degrading and needing replacement prior to failure?

 

Any thoughts?

My first thought that's a good link Kevin and EVERYONE should read it.

Any high pressure fluid system failure or accident could cause an injury resulting in amputation or worse so take care.

 

My opinion on hoses is above all to avoid close contact when under pressure. Use protective coils etc for abrasion resistance only where necessary but do not rely on them to protect you against wayward fluid. Robust conduit or solid flexible cover must be strong to warrant its use at the expense of visual inspection. I would be tempted to do this if I was expecting to work very close to the hose though. Inspect all hoses as often as you can, even ones with shields and change if you have doubts. However few of us will change a sound hose purely on age but if its in a critical position or system then it's a probably a good plan.

Probably a bit more advice than you were expecting John, also you could inspect, and change hoses regularly and one could still burst without warning, just the luck of the draw but you will have minimised the risk.

I think cost is a barrier to changing pipes that seem OK. My mower for example has 11 pipes that you can see from the outside and a few more under the bonnet. At £40 to £60 plus VAT each it becomes a big bill to change them just in case.

Non of them are going to hurt you when under the high pressure from actually working though as the body of the machine is in the way if you are sat on the machine.

This is much more of a PUWER issue than LOLER
