It was interesting to read the new edition of Surface World, here in the UK, and in particular the article relating to the flash point of different solvents by Sydney Treacher. Surely this is 'red herring' designed to divert the attention away from the issue of nPB re-classification. Whilst acknowledging the dubious means of calculating the flash point of nPB which led to a category of R11 it still cannot detract from the situation surrounding the use of nPB. Also it seems that this is a matter of the solvents industry indulging in the 'airing of their dirty washing' in public. Far better that all solvent manufacturers should be publishing positive messages to their customers.
The letter to the editor from Mike Etkind at DEFRA properly outlines the current legal classification of all nPB based products in Europe which is as follows.
nPropyl Bromide

R67; Vapours may cause drowsiness and dizziness

We still have no definitive proof that nPB will be classified as anything other than R60. As the implications of the SED are almost upon us it seems that users will have to quickly re-assess their requirements and whether or not they should register their process.
It is interesting that Mr Derek Carpenter, of ETE, has had plenty to say over the years about the re-classification of TCE yet he remains virtually anonymous at this important time for solvent users in Europe. Not even a word from him in the latest edition of Surface World magazine in the UK which is interesting as he has had something to say in virtually every issue over the last 3 years.
He will also have been aware that the subject has been debated here and again he appears to have lost his voice.

It's very near to the SED deadline date and I would only hope that ETE have informed their customers that they need to be below the 1 ton limit or they must register their process.

As we progress ever nearer to the 31st October, nPB based products are still categorised as R60.
This means that all users will be non-compliant if they use over more than 2 tons.
In addition there is also the necessity to consider substitution within the shortest possible timescale.
We must therefore assume that that there will be warnings in Surface World magazine and at the exhibition making it patently clear to all users.
It will be interesting to see exactly how professional, ethical and responsible the distributors and manufacturers of Ensolv, Leksol and Lenium are at this important time.

I see there was no warning in Surface World magazine. It is perfectly legal to use nPB products, under the correct circumstances, but we do need proper guidance.
The question I would like the answer to is; What should users of nPB products do after October 31st if they use over 2 tons of product? Surely they must register their process under the SED.
