In answer to the original question I would revise CoSHH.

I would put the duty on the manufacturer to provide a standard CoSHH assessment for each of their products. The user would then have to review the assessment and make sure they were using the chemical in the way described. If not they would have to do a CoSHH assessment themselves.

At the moment we have thousands of users performing CoSHH assessments for chemicals they all use in the same way. The saving to industry would be huge without a great increase in risk.

Would also take a lot of confusion out of CoSHH.

The duty would still remain on the end user to ensure people are informed / trained etc.

ARE YOU LISTENING HSE!!!!!!!!!!!!!!!!!!!!!!!!!

But you still have to do a CoSHH assessment, right?

One thing which does need changing is the repeated depiction of diagrams in guidance by HSE about display screen equipment (DSE) which show DSE users looking at screens perched on the tops of computer boxes. Surely this tends to reinforce to many people their misperception that screens should always be placed in this manner. The reality is that the vast majority of DSE users are not touch typists and therefore look repeatedly between their keyboards and screens when typing. If screens are located at a significant height above keyboard level, users have to move their heads up and down to a considerable degree and therefore face a greater likelihood of related neck problems.

Admittedly this point is not strictly about changing OS&H legislation but rather about guidance which is closely related to legislation about DSE. My view is that most pieces of most OS&H legislation is okay and doesn't need changing. Some legislation is excellent, notably the main sections (i.e. 2, 3 & 7) of the Health and Safety at Work, etc Act 1974 which strike me as having been very skilfully drafted and are likely to remain valid for the foreseeable future. What DOES need reviewing is how some bits of some legislation are interpreted and explained.
