What should be noted when clearing a workshop after maintenance?
Thread Content
Summer has arrived, and I heard that maintenance work is going to start at the workplace. This year, the workshop where I work will undergo extensive renovations involving the use of fire. So I’m getting ready for that. 、
There are too many things to keep in mind; it’s impossible to explain them all at once
As long as the maintenance tools are not left inside the container.
It mainly concerns the transfer of solvents within the workshop, as well as the methods for cleaning the storage tanks, condensers, and reaction vessels there, along with the sequence in which these cleanings are carried out.
There must be at least a plan before carrying out maintenance, outlining when each task will be done. Parking, emptying the system, what it hands over, and so on. During maintenance, things can get busy, but special attention must be paid to high-altitude work. For equipment that is still under power, it’s necessary to lock out the equipment before carrying out any maintenance tasks; there are many details to take into account
Before starting hot work, isolation, emptying, and replacement must be completed successfully; tests prior to the operation must yield positive results, and protective measures must be in place.
Follow the rules: do things one by one. Isolate, empty, and replace the area before starting any fire-related work; ensure that tests are passed prior to beginning the operation, and that proper protective measures are in place.
Attention must be paid to ventilation, dust removal, electrical protection, etc.; combustible gases should not accumulate to prevent flash explosions of combustible liquids
Six prohibitions for hot work: 1. Hot work is prohibited without an approved hot work permit. 2. Hot work is prohibited if the area cannot be reliably isolated from the production system. 3. Hot work is prohibited if cleaning and gas displacement are not done properly. 4. Hot work is prohibited if flammable materials in the surrounding area are not removed. 5. Hot work is prohibited if hot work analysis is not conducted on time. 6. Hot work is prohibited in the absence of fire-fighting equipment.
Preparations for maintenance: 1. The system has been properly purged, and there is an analysis report available. 2. Safety helmets and work uniforms must be worn properly. 3. The scaffolding must be inspected, and the safety belts must also be checked properly. 4. Welding machines, oxygen, and acetylene cylinders must be checked properly. 5. A hot work permit, a temporary power use permit, and a height work permit must be obtained. 6. Electric hoist tools must be properly inspected. 7. The maintenance area is free of debris.
