What are emergency keys characterized by?

Emergency keys are characterized by being color-coded and notched, which serves a specific purpose in emergency situations. This design allows for quick identification and easy accessibility during high-pressure scenarios, such as when a rapid response is essential. The color coding helps personnel to quickly distinguish these keys from regular keys, reducing the risk of confusion when time is of the essence. The notches are specifically designed to fit locks in emergency exits, ensuring that the right key can be readily found and used effectively in urgent situations.

This particular combination of features is crucial for efficient response during emergencies, as it allows authorized personnel to act swiftly to unlock doors or gates that may need to be accessed.
