PLEASE READ NOW AND TAKE ACTION
Dear MSA Customer,
MSA is issuing this User Safety Notice to inform you of a PROCEDURAL UPDATE regarding usage of the Altair 5X PID gas detector.
MSA has determined that PID sensors manufactured from March 2020 to and including June 2023 may not respond to gas after being turned on due to the lamp of the sensor not lighting upon startup and the Altair 5X PID will not display a PID lamp error.
To verify the proper operation of the Altair 5X PID, perform a BUMP TEST OR MANUAL GAS CHECK each time the unit is turned on and prior to using the device.
MSA has not received any reports of injuries due to this condition. However, it is necessary that you perform the actions outlined in this notice.
To verify proper device operation, PID sensors manufactured from March 2020 to and including June 2023 must have a bump test or manual gas check performed each time that the unit is powered on, prior to use. This requirement is in addition to existing usage guidelines.
