How to effectively manage gas detectors installed in factories?

1.Identify the risk, correctly plan and set up gas detectors

Organize process, equipment, instrumentation, safety and other aspects of the professionals, while contacting the design unit, together with the analysis of raw materials and materials involved in combustible, toxic gases, identify the parts of the possible leakage, in particular, the study of gas compressors and liquid pumps, dynamic seals, liquid sampling ports and gas sampling ports, liquid (gas) and air venting ports and liquid (gas), often dismantled flanges and frequently operated valves and so on. Arrangement around the release source, to prevent the detector should be set up not set up and set up the wrong type of situation.

2. Precise calculation, reasonable setting of toxic gas detector alarm value

Different levels of alarm signals should be significantly different, according to the toxicity of toxic gases, at least set two levels of alarm.

3. Positive response, strengthen the detector alarm signal management

Establish the detector account, verify and confirm with the layout plan, and draw the combustible and toxic gas detector detection point layout for the whole plant and each device, so as to facilitate the management and rapid processing of alarms. Fire control room personnel should strengthen the monitoring and management of combustible gas secondary alarm signals and alarm control unit fault signals, which should not be shelved or ignored. Control room operation area and regional alarms should be set up sound and light alarms, to prevent the environment is relatively noisy, can not hear the alarm. Strictly prohibit business personnel due to frequent alarms and other reasons, unauthorized closure of the alarm, should be strengthened alarm system management, the establishment of the first responsible system, the first time to find and dispose of dangerous situations.

4. Preventive, scientific disposal of gas detector alarms

Organize relevant personnel training, standardize the filling of combustible and toxic gas alarm records. Strictly comply with the abnormal disposal process, after receiving the alarm of GDS system, the control room personnel will determine the alarm instrument number and specific location, make the alarm record at the first time and notify the personnel to confirm the cause of the alarm.

5. Regular maintenance and calibration of gas detection and alarm devices

Regular maintenance, carefully find the root cause of the alarm, such as gas leakage in the measured environment, unreasonable alarm value setting, not calibrated on time, damaged sensors, equipment wiring problems, and so on. If the instrument is subjected to severe vibration or shock, or important parts are replaced or repaired, it should be calibrated in time. If the detection and alarm device is found to be out of calibration or malfunctioning, it should be repaired or replaced immediately.
