Once again I repeat that the safety data sheet is written for CHIP and not for COSHH. In fact, if you consult the COSHH Regulations as to what constitutes a substance hazardous to health you will find among other definitions the following:
“(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.”
Thus, under certain circumstances even water can be a substance hazardous to health. In fact, studies show that wet work is the most common cause of occupational contact dermatitis.
As far as the WEL is concerned, I do not think that this is strictly relevant. Respiratory uptake (and this is all the WEL relates to) is almost certain relatively unlikely.
Without doubt, sulphamic acid is irritant to the skin and eyes. Thus a risk assessment needs to be done to establish what the potential for skin/eye exposure might be and what action you then need to take to manage such exposure such that damage to health will not occur.
Probably, given the nature of the use, adequate control can be achieved by the use of good quality, reasonably thick natural rubber gloves and appropriate eye protection, but you may need also to take into your assessment the possibility of splashes to the face, spillage etc. You may also wish to consider how it is being applied and whether there are better methods for this.

Thanks Chris/Adrian

I was aware that the SDS was more appropriate for CHIP and not COSHH. My personal thoughts were that since the product is going to be used in a similar way to your average toilet duck-style cleaner then the controls that you suggest are the most appropriate.

Thanks again
