Abstract

PURPOSE:To work in safety in an environment of inert gas by preparing an gas environmental condition in a tank where inflammable gas is substituted for inert gas before entry into the tank from open air. CONSTITUTION:When a personnel under work in a tank 2 finds his constant air supply system inoperative, it must be substituted for an emergency air system. A distribution air feed pipe is used to connect his own female coupler 10b of a distribution valve 10 with other personnel's female coupler 10c or 10d of the distribution valve 10. Then he is supplied with air from the air feed pipe in normal operation and continues the work. After a closed-type door is shut off, opening a valve 4a1 is permitted to feed inert gas into atmosphere communication room 3e through the findings of having analyzed a gas by an analysis recorder 8. An inert gas for the inflammable gas is contained in the tank, that provides safety of the work in a tank.
