Should hydrogen combustible gas detection points be arranged in a grid pattern on the floor plan?
Thread Content
As the title suggests, the design institute requires that hydrogen, as a flammable gas, be monitored with detection points arranged in a grid pattern on the floor plan May I ask the experts, which standard does this requirement originate from?
This question is a bit strange. The placement of measurement points is determined based on the detection range of the measuring instruments themselves and the layout plan, right? Since your site is quite large, it makes sense to arrange the points in a grid pattern.
The layout of flammable gases is primarily governed by GBT50493; the latest version is likely from 2019. Hydrogen is considered a flammable gas. For sources located indoors, the radius is 5 meters, while for those in open or semi-open areas, it is 10 meters. It is not clear whether there are any other specific regulations applicable to certain industries
