Regarding the issue of cylinder inventory in the analysis laboratory’s cylinder room
Thread Content
During one of the expert inspections, it was pointed out that there was an issue of excessive storage in the gas cylinder room of the analysis laboratory; storage should be carried out in strict accordance with the requirements outlined in Article 3.1.2 of the \"Code for Fire Protection Design of Buildings\" (GB 50016-2014), so that the hydrogen concentration remains at 1 L/m3. The air volume is 5 L/m3; the small cylinder room has only 48 m3, allowing space for just 1 (40 L) hydrogen cylinder, which is far from sufficient to meet actual needs. According to the Standards for Safety Production Standardization in Machinery Manufacturing Enterprises (AQT7009-2013), 4.2.27.4.3 states that at the work site, the number of gas cylinders stored in one location shall not exceed 20; if there are more than 20 cylinders, a secondary gas cylinder storage facility must be established.
Now, we would appreciate it if the experienced members of this forum could advise us on how to make the gas cylinder room in the analysis laboratory compliant with regulations and laws, while also ensuring it meets the needs of daily analysis.
In this case, there is a conflict between two different standards regarding the requirements for gas cylinder storage capacity. Since the Code for Fire Protection Design of Buildings (GB 50016-2014) is a mandatory standard, it generally has higher legal validity and priority in enforcement. The specified storage density is intended to ensure fire safety by limiting the amount of flammable and explosive gases that can be stored indoors, thereby reducing the risk in the event of a fire. On the other hand, the \"Standards for Safety Production Standardization in Machinery Manufacturing Enterprises\" (AQT7009-2013) may be applicable to the specific operating conditions at the production site; under certain conditions, it allows up to 20 gas cylinders to be stored in the same location, probably due to the requirements of the manufacturing process and the convenience of on-site operations. Regarding the situation you mentioned, if the cylinder room in the analysis laboratory has only 48 cubic meters of space, then according to the Code for Fire Protection Design of Buildings, it is indeed possible to store only one 40L hydrogen cylinder there, which clearly does not meet the actual requirements. In this case, there are several possible solutions: 1. Redesign and reorganize the layout of the analysis room to create more storage space between the gas cylinders, in order to meet actual needs while also complying with fire safety regulations. 2. Construct a secondary gas cylinder storage facility that complies with regulations, store excess cylinders in a location appropriate from the work site, and ensure the safe transportation, use, and storage of these cylinders. 3. Consult with the local fire department or safety regulatory authorities to see if it is possible to obtain special permits that allow for an appropriate increase in storage levels based on actual needs, but this usually requires additional safety measures. 4. Consider other alternatives, such as using different types of gas cylinders or changing usage habits, to reduce the demand for gas cylinders. Under any circumstances, ensuring the safety of the analysis laboratory is the top priority; relevant safety regulations must be strictly followed and necessary safety measures taken. It is best to consult professional fire safety experts or relevant **organizations** for more specific guidance and assistance. .
Can it be replaced with a liquid storage tank? Think differently. We used bottled argon before, but later switched to liquid argon
In our chemical plant’s cylinder room, there is generally no more than 1 full cylinder at a time, and no accidents have occurred so far. After all, this is a ventilated environment.
For liquid argon, it involves vaporizers, and it is presumably produced by you and delivered directly, right? Most companies fail to meet the requirements
The safety production standardization regulations for mechanical manufacturing enterprises that you mentioned – for our chemical industry, expert inspections still follow standard 50016
