About this chapter: Chapter 17 provides objectives, functional statements and performance requirements for managing the impact of a fire event in a building or facility. This chapter assumes that a fire can occur in the facility despite any "prevent fire" measures that are being taken. The objective is to limit the impact of a fire to an acceptable level on the occupants, the general public and the facility, including its contents, use and processes. Other inherent objectives in this chapter are to provide some level of protection for the facility's mission and revenue stream and the community tax base.
Facilities shall be designed with safeguards against the spread of fire so that persons not directly adjacent to or involved in the ignition of a fire shall not suffer serious injury or death from a fire, and so that the magnitude of the property loss is limited as follows:
- Performance Group I—High
- Performance Group II—Moderate
- Performance Group III—Mild
- Performance Group IV—Mild
Design fires and fire scenarios shall be chosen to provide appropriate factors of safety to provide adequate performance by accounting for the following factors:
- Effects of uncertainties arising from construction activities.
- Variations in the properties of materials and the characteristics of the site.
- Accuracy limitations inherent in the methods used to predict the fire safety of the building.
- Variations in the conditions of facilities, systems, contents and occupants.
