Not a product we use so i just looked up the safety data sheet for w ell know brand from a well known building trade/diy suppler - as usual its pants! List lots of hazard phrases for the constituents, but nothing for the final product. It also states that during spraying you should use respiratory protection Good look with spraying a paste! Under the section of toxicology it says no thresholds have been met for it be classified as as toxic in any way.

A COSHH assessment should be based on the hazards of use - i see people talking about COSHH cupboards and all two often they are actually referring to storage for fire safety with is classified as a safety Risk by HSE on Health. Again the data sheet states its a paste that melts at 0C and boils at 100C (the sound you can here is me banging my head against the wall)

None of which is very helpful in you deciding on the risks of using or storing the product. Do not forget that the absence of hazard label means a substance is safe - just that its not required under CHiP (which is where the data sheets come from not COSHH) we used to have a very learned colleague on this site who was an expert in skin exposure (not seen him for a while hope hes ok) who would tell you one of the biggest causes of Occupation Dermatitis is wet work with H2O - i.e tap water.

You might want to go back to the supplier of your particular product and hope there safety data sheet is clearer, but as i say dont rely on it.

Sorry i dont feel i have been much help but very difficult to give you a yes no answer on teh information supplied.

I will follow HSSnail lead and state you need to ask the supplier for a current Safety Data Sheet - quick search on the internet and Caulk SDS throws up a myriad of documents of varying ages but more particularly of varying composition which impacts the classification - some of the older documents mention susbstances that are now present on various REACH annexes.

Then you need to go back to the "how" do you use it - even if the caulk has no hazardous substances could you for example end up sanding or drilling the dried material creating dusts?

That comment from HSSnail about spraying may be associated with harmonised classifications of Titanium Dioxide.

There is no legal requirement for ordinary products to be kept in some sort of magical safe.

Has anyone told you that you need one.

Again all two often as an ispector used to find a COSHH cuboard which was just a collection of every chemical they had - created a much greater risk by mixing incomparable chemicals which would have made a spill very hazardous indeed.
