What does NFPA 13 state about the use of antifreeze in sprinkler systems?

• A. It can be used in all applications
• B. It must have specific concentration limits for use
• C. Only non-toxic antifreeze is permitted
• D. It should be avoided entirely

Answer: (B)

NFPA 13 outlines important guidelines regarding the use of antifreeze in sprinkler systems to ensure safety and effectiveness. The correct answer highlights that antifreeze must adhere to specific concentration limits for its use. This requirement is critical because using antifreeze solutions that are either too concentrated or too diluted can compromise the efficacy of the sprinkler system, potentially leading to insufficient fire suppression or system damage in cold weather. The guidelines focus on preventing issues such as the freezing of water in the piping system and ensuring that the antifreeze concentration does not result in flammability or other hazardous conditions. This balance is essential for the reliability of the sprinkler system during emergencies. Overall, by establishing concentration limits, NFPA 13 aims to ensure that antifreeze enhances the system's performance while maintaining safety standards.
