Which of the following gases is typically NOT handled by Type III Low Pressure Equipment?

Type III Low Pressure Equipment is designed primarily for the handling of specific types of gases that are typically used in residential and commercial applications. These gases include natural gas, propane, and butane, all of which are common fuels used for heating, cooking, and other energy needs.

Chlorine, on the other hand, is a hazardous gas primarily used for water treatment and disinfection in pools, and it requires specialized equipment that can safely manage its toxic and corrosive properties. Because of the inherent risks associated with chlorine, including its ability to react with other substances and its potential for creating harmful environments, it must be handled using equipment that is specifically designed to contain, transport, and deal with these properties, which falls outside the scope of Type III Low Pressure Equipment. This includes materials that are resistant to corrosion and systems that can maintain a safe operating environment.

In summary, the correct identification of chlorine as the gas that is not typically handled by Type III Low Pressure Equipment highlights the importance of using the appropriate equipment for different types of gases based on their physical and chemical properties, ensuring safe handling and compliance with necessary regulations.
