The use of hazard signs and labels in the workplace is undergoing rapid transformation due to regulatory changes and best practices. Take the following, for example:
ANSI Z535 standards to visually alert people to hazards were revised in September 2011. Z535 is comprised of six standards: safety colors; environmental and facility safety signs; criteria for safety symbols; product safety signs and labels; safety tags and barricade tapes (temporary hazards); and, product safety information in product manuals, instructions, and other collateral materials.
