Are biohazard warning labels required for any or all linens?

Biohazard warning labels are typically required for linens that have been contaminated with potentially infectious materials, such as blood or other bodily fluids. In healthcare settings, such as hospitals or clinics, any linens that pose a risk of infection must be properly labeled and handled according to specific regulations. However, not all linens require biohazard labels; it depends on the context and the type of contamination involved. Always refer to local health and safety regulations for specific requirements.
