The EBA is worn on the back of the operator under the encapsulating protective suit. The EBA is a combination of in-line regulator and self-contained breathing apparatus. The EBA tether line connection connects to the encapsulating protective garment passthrough assembly from which air is supplied through a tethered air line from a remote air source. The EBA has an in-line air filter and vent tubes which provide cooling air to the extremities. An in-line regulator provides breathing air "on demand" to a multi-size face piece. An air cylinder, mounted on the back of the EBA provides six to eight minutes of escape air at a rate of 40 liters/minute should the remote air supply be interrupted. A battery powered warning light is mounted on the face piece to alert the operator when the cylinder air supply is running low. A protective cushion cover is provided to protect the encapsulating protective garment from the metal components of the EBA. 1-7
