Black fiberglass tissue can pose safety concerns due to its fibrous nature and potential to cause skin irritation, respiratory issues, and eye injuries. To mitigate these risks, it's crucial to wear appropriate personal protective equipment (PPE), including gloves, safety glasses, and a respirator mask. Avoid inhaling dust or fibers, and ensure proper ventilation in the work area. Skin contact should be minimized, and any contact should be followed by thorough washing with soap and water. Dispose of the material according to local regulations to prevent environmental contamination.
