Which type of signs are mandated where an immediate hazard exists?

The type of signs mandated where an immediate hazard exists is danger signs. Danger signs are specifically designed to indicate a high level of risk or an imminent hazard that could result in serious injury or death if not addressed promptly. The color scheme typically involves a vivid red background with bold black lettering, which enhances their visibility and urgency.

These signs serve as critical warnings to ensure that individuals are alerted to the existence of severe hazards that require immediate attention or caution. In environments such as construction sites or industrial settings, any indication of a situation that could lead to severe injury or fatal consequences demands the use of danger signs to mitigate risks effectively.

Caution signs are used for situations that may lead to minor or moderate injuries but not for immediate threats, while warning signs indicate potential hazards that could lead to dangers without the same level of immediacy or severity as danger signs. Exit signs are unrelated to hazards and primarily guide people to safety avenues during emergencies. Thus, danger signs are essential in situations where immediate actions are needed for safety.
