Obtain a permit for working in confined spaces, conduct gas analysis, and assign a supervisor.
The top priority in working in confined spaces is to completely disconnect all pipelines that carry materials in and out, close the valves, and install blind flanges on certain specific areas. Ensure good air circulation, provide safety ropes and dedicated supervisors. It’s never too much to do more. Before starting the work, relevant books, tickets, and certificates must be properly prepared; in particular, sampling and analysis must show satisfactory results before entering confined spaces, and sampling and analysis should be carried out at regular intervals as needed.
