What is the primary reason chlorine sanitizer needs to be monitored continuously?

Chlorine sanitizers are widely used in food service settings due to their effectiveness in eliminating harmful pathogens. However, a key characteristic of chlorine is that it breaks down quickly when exposed to various conditions, such as light, heat, and organic matter. This rapid degradation can significantly reduce its sanitizing power, making it crucial to monitor the concentration of chlorine in the sanitizer solution continuously.

Regular monitoring ensures that the sanitizer maintains the appropriate concentration level required for effective disinfection. If the concentration drops below the necessary levels, the sanitizer may not effectively kill bacteria and other pathogens, which could pose health risks in food handling and preparation areas. Thus, continuous monitoring is essential to ensure food safety and compliance with health regulations.

In contrast, other listed options focus on different aspects of chlorine yet do not directly address the necessity for continuous monitoring based on its effectiveness as a sanitizer.
