Which of the following should not have anything placed in front of it?

Fire pull stations are critical components of a facility's fire safety system. They are designed to allow individuals to quickly and easily alert others in the event of a fire emergency. Placing any object in front of a fire pull station could obstruct access and delay the response time during a critical moment when every second counts. This could potentially put lives at risk, as it may hinder the ability to activate the fire alarm system when necessary.

In contrast, while patient exam rooms, medical record archives, and laboratory storage units are important areas within a healthcare setting, the urgency associated with immediate access to fire pull stations makes it clear why they must remain unobstructed at all times. The focus on safety ensures that fire pull stations are always readily accessible for emergency situations.
