Manufacturing & Engineering N'I' Radiation risks
Rank: Forum user
|
Hello all,
I've recently crossed industries to implement a management system for an engineering company. It's the first time I've read the CAOR 2010 and its requirements. I fear I'm likely to be taking it too literally but I'm happy to do the proverbial 'long hand' working out as it will enable me to reach an efficient process afterward.
My question to anyone in the industry is where can I find data on the artificial optical radiation emitted from welding to meet the requirements of regulation 3(5)(a) of the regulations? I haven't seen it as yet within HSE guidance though will move to industry guidance soon - but thought I'd ask the experts on here.
Thanks in advance

Update:
Some internet sources quoted wavelengths, and relative harm where outside of optical light range i.e. 400-700nm.
However, when assessing risks, I believe we need to measure millisivierts, and here the conversion or information runs short.
To reiterate my point in my original post, maybe I'm looking at too much detail to say controls are already in place, but has anyone got any previous experience in demonstrating they've met the requirements of the COAR regulations regarding assessment considerations?

Sieverts are related to ionising radiation I believed, but it's been a while!!!

Yes it is worrying considering Sieverts (more likely millisieverts) when discussing NON ionising radiation.

Thank you Ian Bell for the useful information. What an excellent and encouraging safety professional you must be.
I try meeting regulations as written and request assistance for comparatively low risk radiation regarding welding arcs. And you point out I had mixed terminology up

Public health England used to have information on their website about the risks from non ionising radiation. they did my training on the subject a few years ago.

Thanks again,
I've looked at the EU non-binding guidance since the post, and a helpful chap PM'd me a link in the right direction.
As I thought, not many would attempt to meet the requirements of regulation 5 in full detail, and safety can be achieved with simple controls. I was simply trying to meet as much of the information required by the Reg's as possible.
Thanks all who contributed.

To try and answer the OP question:
Risk Assessment must take consideration of—
(a)the level, wavelength and duration of exposure
Where can I find data on the artificial optical radiation emitted from welding?
The intensity and wavelength of UV emitted from welding will vary according to the type of welding and the rate of shield gas used:
http://annhyg.oxfordjour...org/content/41/1/95.long
http://annhyg.oxfordjour...ontent/45/7/597.full.pdf
(both free)
The wavelength you can assume the range, the duration you can know or set, the level however is more difficult, but if your control is to eliminate the risk through covering skin and filtering eye protection (not time weighting exposure) any such measurement in this case seems arbitrary?
Examples of measurements and results do exist (see above journal entries) if required and also here I found:

For shading type and filters for eye protection there is plenty of guidance available, such as:

Descarte8,
I haven't looked but I already know I owe an equal thanks as to those earlier. I'll look at those once back at work. And again, thanks to all with helpful contributions - I must be on the right path if other are as knowledgeable as this.
I'm looking at a course with PHE too in case anything gets more complicated in the future
Gratefully endebted
