Not all manufacterer Data Sheets where availiable but a few worked.
The white silicone paste we use doesn't tell us much on the package.
Every company that puts up for sale chemicals is required to provide a safety data sheet for the product, in which it is reported, among other information, the risks to humans and the environment.
You can usually find the Safety Data Sheet of the product in the web of the manufacturer. As I have said, It's a requeriment.
If you tell me the thermal compound that you use, I could try to find its SDS.
Anyway, It's your company responsability to give you the SDS of each chemical product that you use. Just ask for it in your job.
