NFPA 557 Standard for Determination of Fire Loads for Use in Structural Fire Protection Design

1.1 Scope

The scope of this standard is the determination of the fire load and fire load density to be used as the basis for the
evaluation and design of the structural fire performance of a building.

1.1.1 The determination of a design-basis fire is outside the scope of this standard.

1.1.2 This document is not intended to address facilities for storage of hazardous materials.

1.2 Purpose

The purpose of this standard is to provide standard methods and values for use in the determination of fire
loads and fire load densities for design-basis fires, which is done using a risk framework.

1.3 Application.

This standard applies to the determination of fire loads and fire load densities based on occupancy.
