What is considered the least desirable access method for fire emergencies?

The least desirable access method for fire emergencies is access codes and access cards. In the context of emergency situations, especially during a fire, time is of the essence. The use of access codes or cards can introduce delays. In an urgent scenario where every second counts, having to input a code or swipe a card can hinder firefighters and first responders from rapidly gaining access to a building to conduct rescues or suppress a fire.

In contrast, having a key holder present allows immediate access without delays, while designated fire department keys are specifically designed to facilitate quicker access for emergency services. Locked emergency exit doors can also pose significant obstacles by preventing egress for building occupants trying to flee. Thus, access codes and cards are seen as the least favorable option in emergencies due to their potential to impede prompt response.
