Before starting your inspection, what calibration state must not be present on the CGI?

Prior to commencing an inspection, it is essential for the calibration state of the Combustible Gas Indicator (CGI) to be accurate and reliable. An expired calibration state indicates that the instrument has not been checked or adjusted according to the manufacturer's specifications for a designated period. This means the readings provided by the CGI may not reflect the true gas concentrations, which can compromise safety during the inspection process. Therefore, an expired calibration state must be rectified to ensure the integrity of the inspection results and the safety of those involved.

Other states, such as 'corrupted' or 'faulty,' would also indicate issues with the CGI that could affect its reliability, but an expired calibration specifically points to the need for a check-in on the device's accuracy over time. Similarly, while 'outdated' may suggest the technology is old, it does not necessarily pertain directly to the calibration state. In contrast, an expired calibration clearly denotes a time-related issue that must be addressed before inspection activities can safely proceed.
