Fire hazard issues in the acetylene workshop
Thread Content
Due to the need for improvements in new processes, the acetylene workshop requests that some supports be welded inside the workshop while production continues as usual. Could everyone please share their ideas on how to ensure safety?
Ensure proper control during the hot work process: 1. Control the source of leaks to guarantee no leakage occurs. 2. Conduct online monitoring during hot work; if the parameters exceed the limits, stop the work immediately. 3. Isolate the gas source using tarps or similar materials. 4. Select personnel familiar with the production process to serve as supervisors. 5. Finally, ensure proper ventilation to remove combustible gases in case of abnormalities, thereby buying time for handling the situation. For the rest, follow the requirements for working in explosion-proof areas.
It’s very comprehensive; I’ve learned a lot from it. Thank you!
It’s too risky to carry out maintenance work while production is ongoing; who would dare to sign such a fire permit? Anyway, I certainly wouldn’t. As a supplementary point, on-site emergency protection measures should be extremely thorough, and fire-fighting equipment must be available; I advise against taking such risks in the future.
To implement new technical improvement projects without having to stop production – that’s really impressive! If welding is to be carried out only in an explosion-proof area, it is sufficient to follow the procedures to obtain a welding permit and to have supervisors and emergency equipment on hand.
For newly introduced technical improvement projects, production must be halted, and the system must be purged with nitrogen or carbon dioxide gas before ignition is possible. If welding is to be carried out only in explosion-proof areas, a welding permit must be obtained according to the procedures, and different personnel shall supervise the work depending on the circumstances. Rather than the technical staff as mentioned on the second floor.
It falls under category 1 hot work, and strict control must be exercised during the hot work process. Ensure proper control during the hot work process: 1.

This is too risky; acetylene is not something to mess with! If technical upgrades are indeed necessary, isolation is the first step: the pipelines of the system to be upgraded must be completely separated from those of the system that is still in use for production, this includes using blind flanges and disconnecting relevant sections. Secondly, the items involved in technical upgrades need to be replaced; fires must not be caused by welding operations. Sewers should be cleaned, and air should be blown into dead corners for replacement. Once again, it is essential to ensure good ventilation; any acetylene remaining outside the pipes must be diluted promptly. **Cooling measures should be taken, and welding sparks that fall to the ground must be extinguished immediately. Finally, there are the fire watcher and fire extinguishers required for normal welding operations. It’s not worth taking such a risk; if there’s a bonus, then it might be worth considering.
Thanks for sharing, coming in to learn a bit!
