Teach you the correct use of portable gas detectors
The operation of the gas detector is quite intelligent, just like a mobile phone, many people can use it, but the instrument is not a mobile phone. Its core function is to detect qualified data. The rigor of the inspection work does not allow us to master the operation method. The safety protection of the instrument is very important, especially the four-in-one gas detector. The safety protection of the instrument is very important. The data accuracy of the detector is directly related to the health and safety of the people. Teach you how to get started quickly
1. Before entering the work section, be sure to carry out a safety check. After doing a good job of corresponding safety precautions, such as masks, gas masks, etc. (see the actual situation of the application), check to ensure the safety of test engineers and avoid safety risks , you can enter the tunneling face inspection.
When the four-in-one gas detection instrument alarms, the excavation face should be withdrawn immediately, and the statistical data of the inspection should be stored. After about half an hour of forced natural ventilation, two measurement inspections should be carried out.
The inspection staff must write the work address inspection results on the confirmation sheet, and take full responsibility for the accuracy of the inspection statistics.
2. After inspection, check the rotation warning signs according to the regulations.
The warning sign should be suspended at the reliable location at the entrance of the work site, and other workers should not roll the warning sign, in addition to prevent them from being harmed by other reasons; workers are allowed to enter the work site when they see the environmental protection aspect.
The on-duty production manager shall supervise and manage the work of the on-duty inspection staff to ensure the reasonable implementation of this requirement.
3. Place the camera of the hand-held oxygen detector in the natural environment to be measured. When there is leakage of the measured gas, the standard value of the concentration value display information will increase. When the alarm preset value is exceeded, the alarm display light will be on, and a tick will sound. .
When the camera moves to the leak source, the marked value of the information displayed on the oxygen detector concentration value display becomes larger, and the reading value is recorded.
4. When the battery capacity of the hand-held oxygen detector is low, it indicates that the rechargeable battery is almost out of power. It should be turned off immediately, and the battery should be charged with the charging head. Each battery charge is 10-14 hours!
5. Battery charging method: plug the switching power supply charging head into the AC220V power plug, then insert the charging plug into the battery charging jack of the detector, and then turn on the main power switch of the four-in-one oxygen detector to supply the detector battery Charging, the environmental protection work light is on, the rechargeable battery light is flickering, the display shows the message '----", after the battery is charged, turn off the main power switch and pull out the charging head
