Applies to workplace signs that communicate regulations, warnings or information, with the emphasis on safety and health. It gives requirements for designing signs, and includes recommendations for selecting and placing them. This standard also includes requirements for signs that are not specifically safety-oriented or health-oriented but are often part of the workplace.
