What color should biohazard labels be?

Biohazard labels are universally recognized for indicating the presence of biohazardous materials, which pose a risk to health. The specific color assigned to these labels is red or orange. This color choice is intentional, as it is easily visible and attention-grabbing, ensuring that individuals handling or coming near potentially hazardous materials can quickly identify risk areas.

Using red or orange for biohazard labels helps to standardize safety protocols within healthcare settings. Other colors, such as green, blue, or yellow, do not communicate the same level of urgency or caution associated with biohazard risks and are often used for other purposes or different types of waste materials. Thus, the choice of red or orange for biohazard labels enhances awareness and compliance with safety practices in environments where exposure to infectious materials may occur.
