Which term describes applying safety standards to existing installations?

• A. New Installations
• B. Retroactivity
• C. Compliance
• D. Testing

Answer: (B)

Retroactivity is applying safety standards to existing installations. It describes when rules updated after a system was installed are required to be followed for that older work, often during renovations, inspections, or when a jurisdiction adopts newer code editions. This differs from new installations, which are built to current standards from the outset. In practice, a building with a preexisting sprinkler system might be required to meet current requirements if it’s renovated or if authorities mandate upgrades to bring the system up to today’s safety level. Compliance and testing are related concepts, but the specific act of applying standards to existing installations is retroactivity.
