Abstract

An air ventilated protection suit includes an air input port, and a flat air duct connected to an inner end of the air input port. The flat air duct has hoses provided therein to separately extend in directions along which air is delivered to a whole interior of the protection suit. The hoses keep the flat air duct in an always unimpeded state, and respectively include an axially extended spiral cut, such that air supplied into the hosts pushes open the spiral cuts to flow from the hosts into the flat air duct via the push-opened spiral cuts. The protection suit also includes an inspection port to allow an air-tightness inspection of the protection suit before a wearer entering into a working environment; and an air-guiding case fitted around each pressure relief valve provided on the protection suit to provide a space for air released from the pressure relief valve.
