When handling a piece of black fiberglass tissue, it's crucial to take safety precautions to protect your skin, eyes, and respiratory system. Always wear protective gloves to avoid skin contact, which can cause irritation. Use safety goggles to protect your eyes from any particles that may become airborne. A dust mask or respirator is necessary to prevent inhalation of fiberglass fibers, which can be harmful to your lungs. Work in a well-ventilated area to minimize the concentration of airborne fibers. If you're cutting or sanding the fiberglass, use a dust collection system to control the spread of fibers. After handling, wash your hands thoroughly and avoid touching your face until you've done so.
