Dräger X-am 5000 Notice D'utilisation page 18

CSA requirement: Measured values over the full scale value may indicate an
explosive atmosphere.
Only applies for class II certification. CSA standard C22.2 no. 152 does not
contain any requirements for class II hazard areas. Therefore this device was
not tested for class II by the CSA. The sensor may become blocked and not
measure the gas correctly or not warn the user that gas measurement is not
possible.
The sensitivity must be tested every day before first use using a known
concentration of the gas being measured corresponding to 25 to 50 % of the
full concentration value. The accuracy must be 0 to +20 % of the daily value.
The accuracy may be corrected via calibration.
CSA requirement: Only the combustible gas detection portion of this
instrument has been assessed for performance.
The instrument has not been classified by the CSA for use in mines.
