Is fiberglass harmful to humans?

Hello, friends, this is Alice from Shandong Ever Leading fibers, i meet and dealing with fiberglass more than 8 years. Recently our factory push one new products: Fiberglas for nails extension and kown that some people think fiberglass is very scary and very bad for health. Then i checked with website and company Technican to check it. Found that:

The biggest harm of fiberglass is skin irritation；Becasue if in workshop, there are fine glass fibers. So need wear glasses, clothes and gloves well. Whether it causes pneumoconiosis, respiratory disease, and carcinogenicity, there is insufficient evidence to be studied.

I usually touch fiberglass products, fiberglass yarns, cloths, roving, mats etc. If not often touch, no big uncomforable.But Fiberglass nail need Modification， during this will much fined glass or micro glass, feel skins a little comfortable. So we advised wear rubber gloves when you do fiberglass nails. Some words hope do help to you. Thanks.
