What type of system is considered when assessing chlorine gas weight thresholds?

• A. Flow system
• B. Process safety management system
• C. Environmental control system
• D. Water treatment system

Answer: (B)

When assessing chlorine gas weight thresholds, a process safety management system is essential. This type of system focuses on identifying and mitigating hazards associated with the use of highly hazardous chemicals, such as chlorine gas. The system is designed to ensure safe handling, storage, and usage of such materials, wherein weight thresholds are critical for safety and regulatory compliance.

By employing a process safety management system, facilities can establish procedures that monitor chlorine gas quantities, thereby ensuring operational safety and preventing potential accidents. These systems also facilitate routine inspections and assessments, which are necessary for maintaining safe exposure levels and preventing leaks or harmful releases.

In contrast, while flow systems, environmental control systems, and water treatment systems play important roles in their respective areas, they do not specifically address the safety and regulatory frameworks directly related to managing the risks associated with chlorine gas thresholds.
