Should combustible gas detection alarms be installed in the drainage ditches of semi-open workshops?
Thread Content
In the soybean oil extraction workshop (Class A), is it necessary to install combustible gas detection alarms in the drainage ditches? Alarms are installed around the workshop leachers; are they still needed?
In Class A workshops, trenches are not allowed; if such trenches exist, they must be covered with lids. A water seal should be installed at the inlet to prevent combustible gases from entering
Just to add. Article 3.6.6 of the Code for Fire Protection Design of Buildings GB50016-2006: Ditches should not be installed within factory buildings. If they must be used, their covers must be airtight. Effective measures shall be taken to prevent the accumulation of combustible gases, vapors, dust, and fibers in such ditches, and the connections to adjacent factory buildings shall be sealed with fire-resistant materials
It’s a semi-open factory building – should it be considered part of the factory building or outside it? Regarding the rainwater collection gutters under the lightweight roof of the factory building, do I think they should be considered part of the area outside the factory building?
Gullies should not be installed inside the factory building; if they must be used, their covers must be airtight. Effective measures must be taken to prevent the accumulation of combustible gases, vapors, as well as dust and fibers in these gullies, and the connections to adjacent factory buildings should be sealed with fire-resistant materials
Upstairs, I think the distinction between the inside and outside of the factory building isn’t clear. In such an open structure without any coverings, with only a lightweight roof, how can we determine the boundary between the interior and exterior areas of the factory building?
Gullies should not be installed inside the factory building; if they must be used, their covers must be airtight, and effective measures must be taken to prevent the accumulation of combustible gases, vapors, as well as dust and fibers in these gullies
Strongly agree. Especially Class A factories. I once saw a factory do this, and then it was ordered to make corrections.
Those upstairs still haven’t answered this question: how to define the area between inside and outside the factory building
