How to safely use a portable carbon monoxide detector in industrial tunnels?
1, Prepare before use
Firstly, check the function and battery level of the carbon monoxide detector. After turning on, check if the detector can start normally, whether the screen display is clear and complete, whether there are any problems with the sound and light alarm function, and whether the instrument response is accurate through simulation testing. At the same time, ensure that the battery is sufficient. If the battery is not enough, charge or replace it in a timely manner to avoid sudden power outages during use.
Regular calibration of the detector is also necessary. Before operation, it can be compared with the standard gas concentration. If the deviation of the detection results exceeds the normal range, recalibration is required or professional personnel should be contacted for maintenance to ensure the accuracy of the instrument's detection data.
2, Standardized operation of usage process
Wear and carry it correctly. Generally, wear the carbon monoxide detector in a convenient monitoring position such as the chest, and be careful to expose the probe and not block it. Be careful when doing homework to avoid collision or falling of instruments, which may affect normal use.
After entering the tunnel, it is necessary to pay real-time attention to the concentration data and alarm prompts displayed by the instrument. For key locations such as tunnel entrances and working faces, multiple inspections can be conducted. Slow down when moving to allow the instrument enough time to accurately detect the concentration of carbon monoxide in the surrounding area.
3, Handle exceptions promptly
If the detector emits an audible and visual alarm, it indicates that the concentration of carbon monoxide may exceed the standard. At this time, the operation should be stopped immediately, and the instrument should be quickly evacuated to a safe area. At the same time, the situation should be reported to the relevant person in charge to avoid danger.
If the carbon monoxide detector has malfunctions such as no display on the screen, do not continue to use it. Replace the backup detector in a timely manner and send the faulty equipment for maintenance to ensure that it can work normally the next time it is used.
4, Maintain properly after use
After using the carbon monoxide detector, it is necessary to record the maximum, minimum, and average concentrations detected, which can provide reference for subsequent environmental safety assessments.
