1. Before entering the working area, safety confirmation must be carried out. After corresponding safety protection is done, such as face shields, gas masks, etc. (see the specific scene used), it is confirmed to ensure the safety of the testers and prevent potential safety hazards before entering the working area. For detection, when the four-in-one gas detection instrument alarms, it should be withdrawn from the working face in time to save and record the detection data.
After forced ventilation for more than half an hour, carry out two measurements and tests. The test personnel must write the test results of the workplace on the confirmation sheet and take full responsibility for the accuracy of the test data;

When the alarm setting value is exceeded, the alarm indicator lights up and an alarm sounds. When the leakage source is reached, the value displayed on the concentration display screen of the gas detector increases, and the reading is recorded;
