What is the primary purpose of a life safety plan?

The primary purpose of a life safety plan is to outline safe evacuation routes. This plan is critical in ensuring the safety of building occupants during emergencies, particularly during fires or other hazardous situations. It identifies clear and accessible pathways that individuals can take to exit the building promptly and safely. The life safety plan also typically includes information on emergency exits, assembly points, and may integrate communication protocols to enhance safety during evacuations.

In contrast, other options focus on areas that do not directly relate to life safety. Cost estimates for construction are concerned with financial aspects of a project, which do not have a direct impact on the safety of occupants. Defining architectural style pertains to aesthetics rather than safety features. Calculating energy efficiency relates to the building's performance concerning energy use and sustainability, which, while important, is not a primary concern of life safety planning.
