Final answer:
The statement that exit route doors must be unlocked from the inside and free of detrimental devices or alarms in case of failure is true, ensuring the safety of individuals in emergencies.
Explanation:
Exit route doors must indeed be unlocked from the inside, per safety regulations. This ensures that in case of an emergency, individuals can evacuate the building quickly and without any hindrances. Hence, the statement is true. Exit route doors should not have any devices or alarms that could restrict use of the route if the device or alarm fails. This is a critical component of emergency preparedness and building safety.
In context with the provided examples, the safety and sequence of actions, similar to the janitor leaving the door open before an escape, or the choice of doors in an evacuation, emphasize the importance of access to unobstructed exits. High-voltage wires, on the other hand, are held aloft by insulating connectors but typically are not wrapped in an insulating material, reflecting how different safety considerations apply to different contexts.
