Hi All,
Can you tell me if I am right in saying that if a chemical is classed as non hazardous, you dont need to carry out a coshh assessment.
Cheers
Lee

dont forget the environmental aspects as non-hazardous for people may not be the same for water etc so a chemical's hazard rating can be different depending on the situation it is used / found in / disposed of etc

lee,
Depends on the nature of the material and the quantity, and how it is used.
As an example a resin, might be classed as non-hazardous if it's not flammable and the vapour is not harmful, but it could be a very sticky resin, it could be hot, and an operator might be opening the valve of a 10 tonne container.....
A COSHH assessment may not highlight any risks but a Risk Assessment certainly will!

Following from Paul's comment, the question is when is a substance not a substance hazardous to health? It is one thing whether it is in the Approved Supply List with a risk phrase. The fact that it is not does not automatically mean that it is not hazardous (see also para. 13 of the ACoP for COSHH).
This is recognised in COSHH, where one of the definitions of a substance hazardous to health is:
“(e) which, not being a substance falling within sub-paragraphs (a) to (d), because of its chemical or toxicological properties and the way in which it is used or is present at the workplace creates a risk to health.”
So in practice you need to identify every chemical - as used, not necessarily as supplied - and then how it is used to establish whether it is hazardous or not.
