This is a surprise! OSHA does NOT have requirements for safety color coding in the workplace. But ANSI does. The American National Standards Institute suggests labeling areas with seven colors for safety or organizational categories. / / Use the same color scheme throughout your facility, using only a few colors. Consistency and simplicity make it easier for workers to remember. / / Employees should have regular training on the color meanings. / / Colored safety tape on floors should be durable and survive heavy vehicle traffic.
