The vacuum, total recirculation and jet flow of the subject helmet was below that normally found in helmets in good operating condition. The erratic behavior of the system after the drill was passed through the jet crifice was due to the solidifed pipe dope particles between the screen and the crifice. When disassembled and washed with carbon tetrachloride, the data obtained was consistent.
