Comprehensive guidelines for setting up, examining, testing, and maintaining these life-saving fire safety systems are provided by NFPA 80, Standard for Fire Doors and Other Opening Protectives. It specifies general performance standards for dampers, fabric safety curtains, protection curtain assemblies, fire windows, and all kinds of fire door assemblies. This crucial standard, which is cited in NFPA 101, the Life Safety Code, building regulations, and fire codes both domestically and internationally, guarantees that these elements function as intended to prevent the spread of smoke and fire inside structures.

Chapter 5 has been modified to include additional requirements for the inspection, testing, and maintenance of special-purpose, horizontally sliding accordion or folding doors as well as the removal of the field labeling requirements. Chapter 6 has been updated to provide new guidelines for reducing excessive clearances, new rules for listing and labeling door closing mechanisms, and updated test standard requirements.
