Which of the following is NOT covered by the NFPA 1403 Standard on Live Fire Training Evolutions?

The NFPA 1403 Standard on Live Fire Training Evolutions specifically addresses the safety protocols, requirements, and guidelines for conducting live fire training exercises to ensure the safety of personnel involved. One of the key areas it covers includes the types of structures that can be used for live fire training, such as acquired structures, and the proper use of flammable liquids and purpose-built training facilities like propane burn buildings.

However, arson investigation is not the focus of NFPA 1403. Arson investigation involves assessing fire incidents to determine if a fire was intentionally set and is governed by a different set of standards and protocols. The NFPA 1403 is about training safety during live fire scenarios, not about investigative processes or legal considerations surrounding suspected arson. This distinction clarifies why arson investigations fall outside the scope of the NFPA 1403 Standard.
