What are installed on elevator doors to keep them in place during a fire?

Fire hooks are devices specifically designed to secure elevator doors in place during a fire event. Their primary purpose is to prevent the doors from being inadvertently opened, which could potentially expose elevator occupants to dangerous conditions or smoke. By keeping the doors secured, fire hooks aid in maintaining the integrity of the elevator shaft, allowing for a safer environment for both passengers and first responders. This is particularly crucial in high-rise buildings where elevator use may be restricted or unsafe during a fire.

Understanding the role of fire hooks emphasizes the importance of fire safety within elevators, making them a critical component of elevator design compliant with safety codes and regulations. Other options like safety latches, emergency stops, and alarm systems serve different functions and do not specifically fulfill the role of securing the doors during a fire scenario. Safety latches may enhance door security under normal operational conditions, while emergency stops and alarm systems relate more to operational safety and alerting occupants rather than securing doors in a fire situation.
