For systems installed prior to September 30, 2012, listed antifreeze solutions are not required until which date?

• A. 2020
• B. 2021
• C. 2022
• D. 2023

Answer: (C)

The date when listed antifreeze solutions became required for systems installed prior to September 30, 2012, is indeed 2022. This requirement aligns with updates in fire protection engineering standards aimed at enhancing safety and reducing the potential risks associated with the use of antifreeze in fire sprinkler systems. Prior to this mandate, the use of unlisted antifreeze products was permissible for existing systems, which highlighted the importance of transitioning to listed solutions for improved performance and safety. Understanding the timeline is crucial for those involved in the inspection, testing, and maintenance of water-based systems, as compliance with these regulations ensures that the systems operate effectively and meet current safety requirements.
