Can anyone help ?
I'm revisiting all my COSHH Assessments and I've hit a problem.
I used to use a web site that was an Oxford Uni resource - it listed all chemicals products (just about) by name or by CAS number and then showed you all the Risk Phrases for that particular chemical as well as other useful info such as alternative names. It wasn't perfect but it was the best I'd found.

But now its gone !

Does anyone know of another online resource that simply links Chemical Names to CAS numbers to Risk Phrases ??

Thanks

http://chemicalwatch.com/clp will supply the information but you need to register and pay.
The best bet is to look at the suppliers’ website. They should have MSDS's on there and they will supply you with any information you need.
PS Risk phrases are going out and are being replaced by Hazard Statements under CLP.

This site gives the new hazard statements for substances registered under REACH.

http://echa.europa.eu/we...n-chemicals/cl-inventory

But it's nothing like as easy to use as the Oxford site was.

I used to use that Oxford uni one too! Try this one...

http://esis.jrc.ec.europa.eu/

On the tabs just under the page heading, click on the "CLP/GHS" tab. In the top left hand side on the screen that opens there is a dropdown selector box, select "Search annex VI". This takes you to a screen where you can enter a search by several options (including name and CAS number).

Hope this helps!

Hi,

Typically I go to the chemical companies web-sites !

For example www.sigmaaldrich.com or www.alfa.com plus many others.
The Phrases can easily be found after searching for either name or CAS Number.

A real bonus here is you can easily download the full MSDS's also.

All for free.

Hope this helps :)

Careful about relying too much on risk phrases/hazard statements for your COSHH risk assessment. There are literally thousands of chemicals that do not have risk phrases but where contact with skin can cause damage to health. Also safety data sheets only give you limited information about the product 'as supplied'. I imagine that, like most organisations, you buy chemicals to use them. In the process they may change, e.g. contamination, heating, mixing, reacting, etc. This can significantly change the hazard. Bioavailability is another issue. For example, the product may contain a sensitiser and this would be shown on the safety data sheet (R43, H317). However, if this is not bioavailable, then the risk of causing a skin allergy will simply not be significant. Of course, if you then process the product so that the sensitiser becomes bioavailable, then you will need to allow for this. I had this with a client using pre-impregnated carbon fibre mat. The epoxy was normally not bioavailable, i.e. little risk of sensitisation or allergic reaction when handled. However, for one operation it was treated with a solvent. This released the sensitising constituent, resulting in a completely different hazard and risk when handled. This illustrates how risk assessments for COSHH must be task based.

So for your risk assessment it is important you assess this based on the hazards that are present when the chemical is used!

Chris, I do not disagree but how would most of us know that in each of our particular cases?

Adrian has the right answer; you need the MSDS from the supplier as that will be for the form of the substance in question. For an extreme example, the MSDS for sheet steel wool is going to be different for steel nano powder yet the substance is the same. Also some MSDS assume you have tanker loads of the substance whereas you have only purchased a small bottle. I saw an MSDS for a thread locking liquid (no names!) that suggested you put on your breathing apparatus to deal with a spill. Take the right MSDS, apply common sense in the context that you will use it.

That's because MSDSs are produced under the CHIP regulations which relates to chemical supply. It's The COSHH regulations where we must consider how WE use the chemical.

Steel wool can quickly be turned into a fine power by cleaning a sanding disc! :)

I wish I knew a simple answer to your question! In my experience of doing risk assessments for skin exposure to chemicals, identifying the actual exposure is not the most difficult part of the risk assessment. Identifying the true hazard is frequently much more complex and difficult.

I tend to work the other way round. The question I ask is: "What is it being used for?" This gives me an insight into what the hazard might be. For example, if it is being used as a degreasant, then it is certainly going to be a skin irritant, as an adhesive there is a very real chance that it contains at least one sensitiser. I can then work back to identify the hazard. The basic approach has to be that risk assessment is 'task based' not 'chemical based'. Don't forget that COSHH is for the CONTROL of substances hazardous to health. I find that the 'control' element is often subordinated to the 'substance' element, which is why so many of the risk assessments I see when I first visit a new client are questionable (and that is often being charitable!).

I think the original post has been answered, so i'll leave this off topic

I have to agree with Chris - even if your using chrome VI, a few minutes of skin contact once in a life time is.... well lets hope its OK :) however constant skin contact day in day out with an 'inert' substance (e.g. water) and you might start to see issues.
The MSDS will not reflect this at all.

I have issues like this with COSHH assessments all the time - COSHH is hard and even as a chemist I get stuck!

Sometimes I find guidance information - e.g. the HSE guidance on flux, much better than a MSDS! It is well worth a Google hunt before doing any assessment.

To finish my random message - a chat with a supplier last week... the MSDS eluded to some odd hazards if the product had repeated contact with skin (what ever that might mean)

me = "so my client is doing (a) then (b) with your product, what standard of glove should I use.
supplier = "it's your job to do the risk assessment"
me = "thanks - *sips tea, yawns* quotes S6...."

I'm really not sure what the answer is - I am tempted to say a bad COSHH assessment is better than none - but this is not the case as the wrong glove might increase skin contact.

let's hope REACH helps!!!!????!!
