Chris, I would be very grateful for a copy of the document.

Thanks for your comments. Yes, risk assessment is sometimes taught.
However....

 

One of the problems I encounter with regard to risk assessment is that some
of the teaching on this misses some important points. This is particularly
the case where skin exposure to chemical hazards is concerned. This is not
unique to occupational health. I question the quality of teaching on this
aspect in many courses, whether for occupational health or health and
safety, e.g. NEBOSH diploma. The complexity of risk assessment for chemical
exposure is frequently underestimated. Even some of the HSE guidance is
flawed and, if followed closely, could result in invalid risk assessments
putting worker health at risk. One classic example is the ACoP for COSHH.
Regulation 2(1)(e) states: "(e) which, not being a substance falling within
sub-paragraphs (a) to (d), because of its chemical or toxicological
properties and the way it is used or is present at the workplace creates a
risk to health". In other words any chemical could, under certain
circumstances, become a hazard, not just those which carry risk phrases.
This is correct. One of the most common causes of occupational contact
dermatitis is wet work, i.e. exposure to water. Yet in the proposed method
for a risk assessment in the ACoP it recommends relying on safety data
sheets, which only need to show chemicals with risk phrases for the risk
assessment. I can easily demonstrate, using COSHH essentials, how one can
arrive at an invalid risk assessment. I still see frequent references to
COSHH safety data sheets, ignoring the fact that these are not produced for
COSHH (as paragraph 13 in the COSHH ACoP confirms) but for CHIP. This is
just one example of why so many of the risk assessments I see are at best
questionable and frequently incorrect.

 

The information on the safety data sheet is limited and only intended as
information about the chemical as supplied. Now we normally purchase
chemicals to use for a particular purpose. In the process we frequently
change the chemical (contaminate, mix, react, dilute, heat, oxidize, etc.)
resulting in very different hazardous properties to what we started with.
Indeed, identifying the true hazard is actually very often the most
difficult part of any risk assessment and may require specialist knowledge
(chemistry, toxicology, dermatology, etc.).     

 

I have produced a simple A4 two page document on this. It shows the elements
in a risk assessment, the sources of information and those factors that, if
not taken into account, can result in a possibly invalid risk assessment. I
will happily e-mail this to anyone who e-mails me to request it.
