In many gases, hydrogen is very light 1 gas, its use is very extensive, although it is non-toxic to the human body, but inhaling too much hydrogen will lead to suffocation due to lack of oxygen, hydrogen is colorless, tasteless and easy to burn, so in use, we still need to install hydrogen alarm to ensure the daily production safety. And when we install the hydrogen alarm, the installation height standard must be required. Do you know what the hydrogen alarm installation height standard requires? The following is a brief introduction by yi yun Tian:

hydrogen alarm installation height standard requirements:

According to the GBT According to the provisions of 50493-2019 Design Standard for Combustible Gas and Toxic Gas Detection and Alarm in Petrochemical Industry, hydrogen alarm belongs to the scope of combustible gas detector. According to the description in Article 3.0.8 of SH3063-1999 "Design Code for Combustible Gas Detection and Alarm in Petrochemical Enterprises", the effective horizontal plane radius of combustible gas detector should be 7.5m indoors and 15m outdoors. Within the effective coverage area, a detector can be set up. Installation is generally in accordance with the outdoor every 15 meters to install a, indoor every 7.5 meters to install a.

Therefore, according to relevant regulations, the installation height of the hydrogen alarm is determined according to the specific gravity of the measured gas and air. For hydrogen, its relative molecular weight is 2, which is extremely lighter than air. Therefore, according to regulations, the installation height of the hydrogen detector should be within 2m above the leakage source, it is convenient for staff to see the instrument screen display and for maintenance personnel to carry out daily maintenance. In addition, when in a closed or partially poorly ventilated semi-open plant, in addition to installing a hydrogen alarm above the leak source, a hydrogen alarm should also be installed at the highest point in the plant where hydrogen is likely to accumulate.

In summary, it is the standard requirement for the installation height of the hydrogen alarm. When installing hydrogen alarms, enterprises must strictly follow the standards. After all, the installation of hydrogen alarms is related to the personal safety of on-site operators and must not be treated carelessly.
