B3 is all about control.
Newly in here is a note on “Meaning of prevention and control (COSHH Regulation 7)”.
The principles of good practice were always in there but they have been made explicit – each principle being written out in full. These are followed by a duplication of the hierarchy of control that was already covered in element B2. This might very well be a mistake. But as I said last week – this (and discussion of the examples in element B2) would make more sense here anyway. No control discussion is complete without the special extra duties for especially insidious chemicals (carcinogens etc) where no “safe” level can really be established. The equivalent part in the international diploma has not changed a sit is based on an ILO code of practice which hasn’t seen the light of an update in donkey’s years (and why not, really, considering that general approach has always been a good bet).
The section on ventilation has been significantly re-worked and expanded. It’s a breath of fresh air. There are now included specific roles and responsibilities covering the LEV owner, supplier and service provider and what’s expected. This reflects the dynamic of how often employers will have LEV designed and installed by third parties.
The LEV thorough examinations are now more explicit – beefed up considerably and reorganised, covering all the stuff that is contained in the official HSE guidance in a systematic way.
The final section on personal protective equipment takes its cue from the equivalent in the international diploma. This is logical because, quite honestly, it was far better organised. It’s not that the National version was wrong; it’s just that it wasn’t layed out in the most helpful way. In contrast, for example, it now basically covers the RPE selection factors in the way that HSE’s guidance covers it. That is atmosphere/substance related factors, task and work area related factors, wearer-related factors and quality related factors.
The skin and eye protection similarly follows the international diploma equivalent.
