The principle of setting the alarm point of combustible gas alarm
1. Toxic gas detection and alarm points should be set up in workplaces where toxic gases exist or are used or produced, and may cause acute occupational poisoning of workers, mainly referring to workplaces that may release highly toxic or highly toxic gases, or that may release a large amount of or Workplaces prone to accumulation of other toxic gases.
2. The detection and alarm points should be set near the release points that may release toxic gases, such as delivery pumps, compressors, valves, flanges, feeding ports, sampling ports, drainage ports of storage and transportation equipment, toxic liquid loading and unloading ports or possible overflow ports , toxic gas filling ports, and easily damaged parts of toxic equipment. In addition, detection and alarm points should also be set for channels and sewage outlets that are associated with the source of toxic gas release and have personnel activities, as well as dead corners and tunnels that are easy to gather toxic gas.
3. When determining the detection and alarm points, the physical and chemical properties, toxicity, flammability, meteorological conditions, production conditions, occupational health conditions and the severity of accidents that may be caused by the tested substances should be considered to achieve effective alarms.
4. For special places where it is known that the concentration of toxic gases in the air often and continuously exceeds the alarm setting value, it is not necessary to set up fixed toxic gas detection alarm points. If it is necessary to enter the workplace due to work, relevant personnel should be equipped with flammable gas alarms and effective personal protective equipment.
5. Under normal circumstances, the places where toxic gas detection and alarm devices should be installed should be fixed. When it is not necessary or the conditions for setting a fixed type are not available, mobile or portable detection and alarm devices should be equipped. In addition, combustible gas alarms should also be used for safety inspections and accident inspections.
The above principles for setting the alarm points of combustible gas alarms are shared here. When combustible gas leakage occurs in an industrial environment, the combustible gas alarm will send out an alarm signal when it detects that the gas concentration reaches the explosion critical point or the alarm setting , Remind the staff to take safety measures, drive the exhaust, cut off, and sprinkler systems to prevent explosions, fires, and poisoning accidents, and ensure safe production.
