"Three steps" to do the chemical plant maintenance energy isolation - preparation
In recent years, some accidents such as chemical leakage, fire and explosion occurred in chemical enterprises during overhaul or project transformation are worth thinking about. These accidents are often related to inadequate implementation and management of energy isolation programs at chemical plants.
Chemical Energy Isolation Plan (Energy Isolation Plan, EIP) is accused of manufacturing all hazardous Energy sources, such as maintenance area to prevent operating machinery or equipment in the production of construction, maintenance, maintenance, project modification may cause personal injury or occupational disease during the period of accidental transmission, start, or a sudden release of Energy the Energy leakage, such as fire or explosion accidents. Usually, the energy sources in chemical plants are electrical energy, chemical energy, dynamic energy, radiant energy, gas energy, thermal energy, hydraulic energy, potential energy and so on. For each specific process pipeline, equipment or instrument overhaul or renovation work, develop a reasonable and complete energy isolation plan, can effectively control the potential dangerous energy source accidental release, protect personnel and company equipment property safety.
Do a good job of energy isolation plan, the author thinks, must start from 3 stages such as preparation, planning, implementation.
At this stage, the administrative staff of the chemical process production plant shall prepare the energy isolation plan according to the maintenance or project operation content and scope. Personnel in the administrative area must pass the training and examination of energy isolation planning procedures, and be familiar with the process flow, production operation points and other energy sources in the process piping equipment. Area personnel to isolate the equipment, pipelines or instruments to prepare cleaning plans, cleaning processing. According to the characteristics, temperature, pressure and harmfulness of the residual materials and chemicals in the process equipment, the cleaning plan must describe and regulate in detail the safe transfer, empelling and drainage of the residual materials and the cleaning plan. The clean up plan must be a detailed Standard Operating Procedure, including detailed procedures, safety requirements, and post-clean inspection methods and standards for site cleaning of process equipment and pipeline residues. If the process medium of process equipment and pipelines is inflammable, explosive, toxic and harmful chemicals, the cleaned process equipment and pipelines need to measure the minimum explosive limit and toxicity of residues through the LEL(Lower Limited LEL) detector and PID VOC detector to ensure safe operation.
Of course, the final clean-up plan must be fully discussed by district operators and approved by district supervisors before implementation and implementation. The implementation of proper cleaning plan is a key factor for the effective cleaning of the residual energy in the process equipment and pipelines in the operation area, which can completely or to the greatest extent clean up the residual process materials and chemicals, and ensure the safety of the overhaul operation area.
