What term means a condition prompting retroactive application of standards?

• A. Unacceptable Risk
• B. Equivalency
• C. 2013 Edition
• D. Liter

Answer: (A)

Unacceptable risk is the condition that triggers retroactive application of standards. When a building or its use creates a level of hazard that the existing protection cannot adequately address, the authority having jurisdiction can require applying the current NFPA 13R requirements to that existing installation to raise safety. This means upgrading protections—such as sprinkler coverage or related provisions—even though the structure wasn’t originally built to meet those newer rules. The other options don’t fit: equivalency refers to an alternative method that provides the same level of protection, not retroactive enforcement due to risk; the year cited is just a publication date; and a unit like liter has no relevance torisk-based retroactivity.
