1.4.2 Retroactivity and the authority having jurisdiction

I could use some input and discussion on 1.4.2 (2013 edition) of NFPA-13: "In those cases where the authority having jurisdiction determines that the existing situation presents an unacceptable degree of risk, the authority having jurisdiction shall be permitted to apply retroactively any portions of this standard deemed appropriate."

Questions:

  • What is an "unacceptable degree of risk?" Is there any criteria that has been established or used when determining what would be unacceptable?
  • Can you provide any stories or examples on where this provision of the standard was used to bring an existing older system up to a later edition of the standard's requirements? What was the concern, or "unacceptable degree of risk?"
  • Any stories or examples of fires that motivated the AHJ to examine an existing similar building or situation, determine an "unacceptable degree of risk" and require and existing older system be upgraded to a newer edition of the standard?

Thanks!
