Bump Test Procedure for Dräger X-am 5000 LEL Detector

BUMP Test Procedure OF Dräger X-am 5000 Gas LEL Detector

Background

Drager X-am 5000 is a renowned and widely used portable LEL meter in the oil and gas industry. A fire and gas system (F&G system) is used in the oil and gas industry for the detection of gas leakage in the process area. The widely adopted practice is that the Fire and Gas system is a separate, standalone, and rugged system having its monitoring available on the plant control system. In addition to this system, there are numerous portable gas detectors are used for the detection of gas leakage. These gas detectors are lightweight and easily wearable. The Dräger X-am 5000 is a portable gas detection device manufactured by Dräger, a leading international company in the field of medical and safety technology. The X-am 5000 is designed for the detection of combustible gases, oxygen, and a wide range of toxic gases. It's commonly used in industrial settings, mining operations, oil and gas refineries, chemical plants, and emergency response situations to ensure the safety of workers and the environment.

Personal Portable Gas Detector

    Drager Xam 5000 is a smart device that provides four channels for continuous gas monitoring. Xam 5000 provides a live reading of gas concentration on its display and has a sounder. Xam 5000 also has flasher red lights that flash in case of alarm. Xam 5000 has two alarm levels i.e.,. A1 and A2. 

Functionality Test of Drager LEL Detector 

Correction functionality of this X-am 5000 LEL detector is paramount in the oil and gas industry. It provides the indication and alert for the presence of gas or gas leakage through sensor detection, then alarms with a sounder and flasher which is essential for personal safety. 

X-am 5000 is also used to initiate any hot job in any hazardous classified area. Based on the reading of X-am 5000 certain mitigation strategies are devised and acted accordingly. 

Frequency of bump test 

The bump test is the test to verify the correct functionality of the Drager X-am 5000 LEL meter and this bump test instantly determines the health of the LEL meter. Depending on the nature of the utilization of X am 5000, the frequency of the bump test is determined. As per the personal experience of the writer, daily bump test was mandatory for the Process Field Operators/Technicians.

Bump Test Procedure for LEL Detector

Following are the steps provided to perform the bump test of the Drager X-am 5000 LEL detector/meter: 

1.    Insert the calibration gas mixture cylinder inside the bump test station.

2.    Insert the LEL Meter inside the station; a click sound suggests that the meter is in place.

3.    Wait for 10 seconds for the gas to flow through the dust and water filter to the sensor(s).

4.    The LEL Meter shall generate alarms with beep sounds in response to the test gas.

5.    A high alarm A1 will occur followed by the high-high alarm A2.

6.    An “OK” message shall then appear on the screen indicating a successful bump test.

7.    If the meter does not generate the alarms, the test is unsuccessful and the meter has to be calibrated. This calibration can be carried out on the bump test station.

8.    Press the button at the bottom of the meter’s slot to remove the LEL detector from the station.

9.    Remove the cylinder from the station and place back safely at its designated place in the lab.

10. Use the gas cylinder with care; do not drop it. Keep away from heat and flame.

11. Close the cylinder valve when the cylinder is not in use and when empty.
