The Fire Safety Evaluation System (FSES) is a system used in the United States to evaluate the overall level of a building's fire safety. FSES applies to health care, prisons and jails, offices, laboratory buildings, and overnight accommodations in National Parks.[1]
FSES values are provided in the National Fire Protection Association (NFPA) Standard 101A, Guide on Alternative Approaches to Life Safety.
A FSES evaluation defines the relative impact of a deficiency or proposed improvement to the building. It also provides a means of comparing the effectiveness of proposed improvements by producing a comparative baseline and readily shows the relative gain in fire safety for proposed improvements.[2]
Fire sprinklers have an extensive impact on fire safety and are therefore allotted a high value in the FSES.
