Abstract (en)
[origin: WO2020104815A1] A powered air personal respirator (10), comprises a housing (26), an oxygen sensor (28) carried by the housing (26), for measuring the content of oxygen in the surrounding atmosphere, and an alarm, wherein the powered air respirator (10) is arranged to trigger the alarm when the content of oxygen falls below a threshold value. The invention also relates to a method of calibrating the powered air respirator (10) by connecting a tubular connector (36) to the sensor (28), blowing air into the tubular adapter (36), obtaining a first reading of oxygen content in exhaled air, and comparing the first reading to oxygen content values expected in the exhaled air to confirm that the device is correctly calibrated.
