Good old Ecrin-Roc

[graham]

I'm still an avid fan of the Ecrin - but also have a Petzl Meteor (for climbing etc.) The guidance on the meteor includes this gem

Warning, because of its design, this helmet is vulnerable to damage from
improper care. Do not sit on it, pack it too tightly, drop it, allow it to contact sharp
or pointed objects, etc.

God only know what would happen if a rock fell on me - I mean if I can damage an helmet by dropping it or just shoving it too vigorously into my pack .....

Point missed. Such helmets - isn't the meteor made of polystyrene foam - are one-shot wonders. When they have suffered one impact or other damaging event, they are no longer safe for use. Packing it in such a way as to put it under sustained pressure from the ironmongery also shoved into your pack whilst in transit from home to crag will mean that it ain't gonna protect your head when you then drop a rock on it.

As far as for neck vertebrae they can compress to absorb impact a certain extent just fine due to the structure of the spine. If over-compressed though, compression fractures can occur and would likely cause general neck/back pain until healed (really nothing to be done, could wear a brace if it helps). </what I learned from neuroanatomy>

A friend contrived to slip on the bottom couple of my stairs on Monday morning. She fell forward on soft carpet.

The result was a fracture of the third cervical vertebrae, attributed to extension of the neck on impact.

Right, I should've added hyperextension as well (flexation when neck bends forward, extension when it bends back) and indeed yeah bend it too far the wrong way = lots o damage. Hence not looking up if someone yells rock...don't wanna get hit in the face/at an angle which would surly destroy a neck, if hit downwards helmet to protect head and also the spine is in better alignment to absorb without so much damage. I dunno how accurate it is but in my neuroanatomy class, the prof said there are certain places on the neck that as little as 2ppi of pressure can cause spinal cord damage/paralysis/death. Kinda scary...

What about those good old Texolex helmets or even those fibre ones we used to use (the ones that changed shape when they got too damp so you had to paint them). Still got a couple in my garage. Reckon they are approaching antique value now! Although I suspect they are still used in some parts of the world.

:bow: Graham.

nice one!

Actually there is a nerve that runs along there, it's a way to see if someone is really unconscious because it /hurts/ to pinch, people will react to it. hahaha

Out of curiosity, can anyone remember who invented / produced the Texolex?

Apparently they were made by Malcolm Campbell Ltd. I believe they had the inscription
"A Texolex Safety Helmet"
"Malcolm Campbell"
"5 Great James Street"
"London WC1"

They may well be appreciated in some countries

Was that a commonwealth games photo ?

I like that he's tied it on with hazard tape
