“Is EN397 2012 a suitable standard for Scaffolding operations bearing in mind the weight of some of the materials e.g. a 21 foot tube being passed down on a strip out of a job”?

 

Should we be recommending EN14052 2005, a high-performance industrial helmet?

Hi,

The best place to start is with the manufacturer or a supplier and speak to them with regards to techinical performance of safety helmets. They will have someone who will be able to give sound and impartial advice on the different types and specification. Particularly in relation to impact performance.

Ultimately the decision following the advice and risk assessment will rest with you, but you would not advise safety spectacles where safety goggles where required.

I hope this helps?

Petzl type climbing helmet with a chin strap!  You ever seen the difference in a hammer falling onto an ordinary Hard Hat & a Petzl Type climbing hat?

Really?  So you expect a hard-hat manufacturer that produces hard-hats meeting EN397 but has none meeting  EN14052 will be offering an impartial assessment of which standard is appropriate?  Conversely, that the manufacturer that has an EN14052 range (which is more expensive, and which its competitors don't have) will provide an impartial assessment of whether EN14052 is actually necesary?

No helmet is going to help you if a 6m scaffold tube falls on you, so references to that as a scenario are pretty much irrelevant.

(6m scaffold tube, say 30kg, 300N.  EN397 is a 50J impact, so that's the potential energy from a 166mm drop - about six inches.  EN 14052 is a whole 100J, or 333mm.  Conversely, I think EN397 uses a conical impactor for a penetration test, while EN14052 is a flat (blade) type impact.  Conical might be closer to the tube-on-end impact?  But the impact case helmets are guarding against is something that weighs 5kg, not 30kg - a helmet isn't going to help if a scaffold tube falls on you.)

Speaking of helmets....

Why don't you call them and find out. Seeing as you know so much you will be able to advise them. Maybe take out shares in their business, so when they do provide the correct safety helmet that protects against even falling aircraft you will be minted when their industry sales rocket. Then you will not have to worry about coming onto forums to sound off to people who are offering a pointer in the right direction.

So pointless wearing anything on your head.

Pointless if the only thing you're worried about is falling scaffold tubes, yes.

That's rarely my only concern when on site, however, so you'll notice that I have never advocated not wearing anything on your head.

I doubt that was the OPs only concern either. Which is why they asked about recommendations for scaffolders in general rather than falling scaffolding tubes.

I think it was also assumed by the poster who suggested speaking to a supplier, to perhaps look at one who supplies a variety of types rather than just the one.

Getting back on track, we used helmets with very reduced peaks as the visibility with a 'normal' site helmet is interfered with by the peak and angles of view can be restricted.

Got ours from JSP, others are available https://www.jsp.co.uk/link/en/head-protection/c/?gclid=Cj0KCQjwsZHPBRClARIsAC-VMPA04--HZhAys6j8mB14jJ_sKU-wjnRDmWwdoo5EmfIaQQwgeU8aJNoaAnwAEALw_wcB
