Self-contained breathing apparatus for selenium hexafluoride (SeF6)

selenium hexafluoride (SeF6) is a toxic, asphyxiating gas with a high risk of suffocation, so we recommend an open-circuit breathing apparatus (ARICO), an air-supply system for long-duration operations and a self-rescue mask for emergency evacuations.
