Z535.1 (Standard for Safety Colors)

Z535.1 is a safety standard that defines the use of colors and markings to communicate hazards and safety information clearly. It helps industries select specific colors for safety signs, labels, and devices so that people can quickly recognize and understand potential dangers or safety instructions. By standardizing colors, Z535.1 ensures consistency across workplaces and products, reducing confusion and improving safety. For example, red often indicates danger or fire protection, while yellow signals caution. This standard enhances communication and helps prevent accidents by making safety information easily recognizable.
