P H,
Let's keep it in context here. You are quoting from an article written for green beeks, as in inexperienced, new starters and all that. The majority of whom have never heard of COSHH, let alone been on a forum, such as this, where the pros and cons of the method have been bounced around umpteen times.
As someone who has handled open radio-active sources, used oxidising concentated acids and alkalis (by the 50 litre drum at a time), processed molten metal ( some in excess of 2200 degrees Celsius) and actually understand the simple/direct warnings on a COSHH safety data sheet, etc, etc., the choice is there.
As I said earlier, if the method had not been mainly superceded by a much quicker and techically easier method, we would all be using the sublimation route now.
There are doubtless others suitably qualified to use the sublimation method, or others who would be perfectly able to use it safely. On the other thand there may/will be some who cannot even handle a 50ml syringe correctly.
