Final answer:
A permit is rescinded during emergencies to allow for rapid responses and ensure the safety of individuals, akin to a 'break glass in case of emergency' protocol.
Step-by-step explanation:
A permit is rescinded when an emergency develops and/or an evacuation of the space is necessitated. This is similar to the concept of a “break glass in case of emergency” safeguard. In the case of emergencies, certain pre-established plans or permits might be quickly cancelled or invalidated to make way for immediate response actions, ensuring the safety and wellbeing of everyone involved.
