What safety issues need to be considered when replacing heat exchangers?
Thread Content
This year, I have a dozen or so heat exchangers that need to be replaced, all located on the 3rd floor. I would like to ask the experts: what safety precautions should be taken on site?
Reply 1# wanlianquan: Has your company implemented safety standardization? If the acceptance is passed, following the procedures specified in the safety standardization documents will suffice
There should be a plan for maintenance and replacement, including safety measures; the most important of these are the proper drainage and replacement of materials, safety during welding work, and safety when lifting heavy objects. As for the other measures, they need to be determined based on the actual conditions at the site and the characteristics of production.
Reply to 1# wanlianquan: Since the third-level safety standardization audit has been passed, follow the requirements outlined in your procedure documents. Specifically, this should include: 1. Training for external construction workers before they enter the facility. 2. Construction plan. 3. Verification of certificates for personnel in special occupations 4. Risk assessment report: which includes: A. Construction organization structure B. Construction equipment C. Job Hazard Analysis (JHA) D. Safety Checklist (SCL) E. Emergency response plan F. Safety protection measures.
1. Check whether it has been drained completely as required； 2. Perform complete replacement and take samples for analysis to meet the requirements ； 3. Construction plan (required: blind plate removal/installation permits, hot work permits, lifting operation permits, high-altitude work permits)
