What is the key feature of a gas-tight recovery system?

The key feature of a gas-tight recovery system is its design to control gas leakage from containers. This system is crucial in ensuring safety in medical environments where various gases are utilized, such as in hospitals. A properly functioning gas-tight system prevents the escape of gases into the atmosphere, which can pose risks to both personnel and patients.

By minimizing leakage, such systems protect the integrity of the medical gases being used, ensure compliance with safety regulations, and help mitigate the potential for hazardous situations. This control is vital not just for the safety of the environment, but also for conserving the gases that might otherwise be wasted.
