More about flame retardants

Thank you for your reply saying that you use nitrogen & phosphorous flame retardants on the covers. I would like to know a little bit more about how safe these are. Do they include either of the following potentially harmful combinations in the Artisan Luxury range?
Halogenated flame retardants.
Organophosphorous flame retardants containing phosphorous bonded to carbon.
Many thanks,
Isobel
