Danger: Indicates a hazardous situation that, if not avoided, will result in death or serious injury. The signal word "DANGER" is to be limited to the most extreme situations.
When to Use "Danger"
Use for Danger Signs for electrical warnings, confined spaces, poison and severe machine hazards. “Danger”, as a header, is becoming less common versus “Warning” signs. The ANSI definition for when Danger should be used has become ever more restrictive – as a way to avoid overuse and “cry wolf” concerns from the past. The traditional OSHA definition for Danger allows for a far broader use than the updated ANSI standards. Limit Danger to potentially lethal environments.
