NFPA 1994 establishes minimum requirements for ensembles and ensemble elements for fire and emergency services personnel exposed to victims and agents during assessment, extrication, rescue, triage, and treatment operations at chemical and biological terrorism incidents.

The requirements of the Standard address the design, performance, testing, documentation, and certification of these protective ensembles that provide protection for fire and emergency services personnel from terrorism agents including dual-use industrial chemicals, chemical terrorism agents, or biological terrorism agents.

The standard establishes three levels of protective ensembles, Class 1, Class 2, and Class 3 ensembles, that could be selected for protection of fire and emergency services personnel based on what the incident risk analysis indicates is necessary protection for the intended operations.
