What should be used when replacing a chlorine gas cylinder?

When replacing a chlorine gas cylinder, using a new lead gasket is critical for ensuring a proper seal. Lead gaskets are designed to withstand the corrosive nature of chlorine gas and provide an effective barrier to prevent leaks. A new gasket ensures that there are no pre-existing weaknesses or degradation that could compromise the integrity of the seal.

Using a rubber gasket or a plastic seal is not advisable because these materials may not be compatible with chlorine gas and could deteriorate quickly, leading to potential leaks. Additionally, relying on an old gasket poses a safety risk, as wear and tear over time can result in ineffective sealing, allowing chlorine gas to escape, which can be hazardous. Thus, employing a new lead gasket ensures both safety and reliability when operating with chlorine gas cylinders.
