Basics of...identification

It’s the law…ANSI Z535 and OSHA 1910.145- Safety signs are required to indicate and define specific hazards that, without identification, may lead to injury or death. Select your sign with the header that indicates the degree of hazard in your application.

Use DANGER to indicate an immediate hazard that has a high probability to severe injury or death.
Use WARNING to indicate a potentially hazardous situation that, if not avoided can result in serious injury or death.
Use CAUTION to indicate a potentially hazardous situation that may result in minor or moderate injury, but not death.
Use NOTICE to provide general information needed to avoid confusion.
SAFETY FIRST, THINK, and EMERGENCY and other similar headings are used with information about housekeeping, first aid, health, medical equipment, sanitation and general safety.
