What does the term “life safety” encompass in building codes?

The term "life safety" in building codes primarily refers to measures and systems that are designed to protect occupants during emergencies. This includes aspects such as fire protection systems, emergency exits, accessibility for first responders, and overall building design that facilitates safe evacuation in case of a hazard. Life safety measures are critical because they directly contribute to the protection of human life by ensuring that individuals can safely escape from potentially dangerous situations, like fires or structural failures.

This focus on occupant protection distinguishes life safety from other concerns in building codes. For instance, energy efficiency measures address how buildings consume energy, which is important for sustainability but does not relate to immediate occupant safety during emergencies. Maintenance protocols deal with the upkeep of building materials, ensuring the building remains safe over time but not necessarily in acute emergencies. Lastly, design aesthetics, while contributing to the visual appeal of a building, do not impact the safety of occupants in emergency situations. Therefore, the emphasis on emergency protection is what makes the answer focused and relevant.
