Is it harmful to my health to use black fiberglass tissue regularly?

Regular use of black fiberglass tissue could potentially be harmful to your health. Fiberglass is made of fine glass fibers that can be inhaled or come into contact with skin, potentially causing irritation or more serious health issues. Prolonged exposure may lead to respiratory problems, skin irritation, and in some cases, more severe conditions like mesothelioma. It's advisable to handle fiberglass with care, using protective gear, and to limit exposure as much as possible. Always refer to the material safety data sheet (MSDS) for specific health and safety information regarding the product you're using.
