What must be readily available for use in emergencies?

The correct answer is that fire alarm pull stations must be readily available for use in emergencies. Fire alarm pull stations are critical components of a building's fire safety system, enabling occupants to alert others in the event of a fire. They are strategically placed throughout facilities to ensure that anyone can quickly report a fire, which activates the building’s fire alarm system.

Having fire alarm pull stations readily available helps facilitate a prompt response to emergencies, potentially minimizing injury and damage. In situations where a fire may break out, time is of the essence, and the ability to alert others immediately can lead to faster evacuations and intervention by emergency services.

While first aid kits, fire extinguishers, and emergency lighting are also important for safety and emergency response, the specific role of fire alarm pull stations in notifying everyone in the vicinity of a fire makes them a crucial element in emergency preparedness. First aid kits are useful for medical emergencies, fire extinguishers are for combating small fires, and emergency lighting assists in safe evacuations, but none of these fulfills the direct need to alert individuals to a fire immediately.
