Frosting around the outlet connection of a chlorine gas cylinder indicates what?

Reduced flow of chlorine gas
High safety risk
Excessive pressure build-up
Chlorine depletion

The correct answer is: Reduced flow of chlorine gas

Frosting around the outlet connection of a chlorine gas cylinder typically indicates that the flow of chlorine gas is being restricted. When the gas exits the cylinder, it rapidly expands, causing a drop in temperature. If there is any obstruction or a significant drop in the flow rate, it can lead to the formation of frost due to the cooling effect associated with the gas expanding and not being able to escape efficiently. This phenomenon serves as a visual cue for operators that something may be amiss with the flow of chlorine gas, prompting them to check the system for potential blockages or issues with the cylinder or associated piping. Maintaining the correct flow of chlorine is crucial for effective water treatment processes, and recognizing the signs of reduced flow is essential for ensuring safe operations. In contrast, other options may not accurately describe the situation; for instance, frosting does not inherently suggest a high safety risk without further context.
