First Edition! Use the 2012 NFPA 557 to assist in the determination of fire loads for use in calculations of the performance of structures in a fire.

The 2012 NFPA 557: Standard for Determination of Fire Loads for Use in Structural Fire Protection Design is a brand new document that provides a methodology for 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.

Developed in response to a request on performance-based design initiatives in the area of fire loads, this Standard covers:

• Design fundamentals
• Development of fire loads
• Occupancy-based fire load density
• Survey method-based fire load density
• Documentation, inspection, and maintenance

Five annexes provide additional clarification of requirements. A valuable tool for architects, designers, engineers, and researchers.
