How are emergency exit doors equipped?
A. They are unlocked from the inside to accommodate the unrestricted flow of traffic
B. They have integrated intercoms that allow you to contact the fire department
C. They are free of devices or alarms that could restrict the use of the exit if they fail to work
D. A and C are both correct
The Correct Answer and Explanation is :
The correct answer is D. A and C are both correct.
Explanation:
Emergency exit doors are specifically designed to ensure safe and efficient egress during emergencies, such as fires, earthquakes, or other situations where quick evacuation is necessary. The requirements for these doors are guided by safety standards, including the National Fire Protection Association (NFPA) and local building codes. Let’s break down the options:
- A. They are unlocked from the inside to accommodate the unrestricted flow of traffic.
This is true. Emergency exit doors must always be able to be opened from the inside without the need for a key, special knowledge, or any unlocking devices. This ensures that in case of an emergency, people can exit the building quickly and without obstruction. In most buildings, this means the doors are equipped with panic bars or push bars that allow individuals to push the door open with minimal effort. - B. They have integrated intercoms that allow you to contact the fire department.
This is not a requirement for emergency exit doors. While intercoms or emergency communication systems may be installed in certain areas of a building, they are not typically part of the emergency exit door itself. Exit doors are more focused on quick evacuation and safety rather than communication. - C. They are free of devices or alarms that could restrict the use of the exit if they fail to work.
This is also correct. Emergency exit doors should not be equipped with devices that could prevent their use in an emergency. While alarm systems might be installed to alert security or staff when an exit door is opened, these alarms should not prevent the door from being used. Malfunctions of security or alarm systems should not prevent the door from opening.
Conclusion:
The correct design of emergency exit doors ensures that they remain functional, accessible, and reliable in an emergency. Therefore, A and C are both true, making D the correct answer.
