Inspection requirements for major hazard sources

1. When the enterprise is closed on holidays, the inspection schedule can be adjusted according to actual circumstances to ensure that inspections of key areas and equipment continue without interruption; it is recommended to conduct at least one inspection. 2. When production is suspended for one day due to the cessation of material feeding, a comprehensive inspection of all critical components and equipment must be carried out to ensure everything is in order before production can resume. 3. During the skill upgrading process, it is also necessary to conduct a thorough inspection of all critical components and devices to ensure that there are no safety hazards during the upgrade, and to check the operating status of each device one by one after the upgrade is completed. 4. When making temporary adjustments to the shift schedule, it is necessary to make reasonable arrangements based on the schedule conditions to ensure that all critical areas and devices are inspected at least once. If no one is working the night shift, it is recommended to conduct another thorough inspection after the day shift ends. .

Inspections were still carried out as required, and feeding was stopped, but the risk associated with your production process remains unchanged, and the risks on site have not been eliminated.

Does that mean that even when there is a full holiday, someone still needs to be assigned to conduct inspections?

Those who make such requests lack understanding of the frontline operations and offer little guidance.

When driving normally, conduct inspections as required； During parking periods/holidays, regular inspections are carried out as scheduled if there is a duty shift ； During inspection, maintenance, or process-related equipment shutdowns, the inspection time has been requested to be adjusted ； Is no one working the night shift? ---What kind of factory is this? Is it in the field of fine chemicals?

During holidays, do facilities that constitute major hazard sources cease to be such sources? Also, for hazardous chemicals that are under strict supervision, if there is no inventory left, are the production process units thoroughly cleaned after being shut down? In such cases, operations related to starting up and shutting down these units pose a greater risk; many safety accidents occur during shutdowns for maintenance and repairs, as well as during the process of starting up and shutting down.

To prepare for the inspection, the chlorine chemical production unit in our factory stopped taking in raw materials during the day shift and began cleaning; no one came to work during the night shift either. No production took place in the production reaction system; the reactors and pipelines were empty. However, in the production workshop, there were still elevated tanks and buffer tanks containing raw materials that had not been emptied.

The process wasn’t stopped; only a certain section didn’t receive any feedstock

Can I understand that in special circumstances, hourly inspections are not required?

The description is incomplete. One must establish an inspection system based on actual production conditions and risks, and organize reviews accordingly. Only the person in charge knows which units will be shut down for a few days or which ones are affected; there’s no way to get an accurate answer by asking here! We’re undergoing a two-month shutdown for maintenance. For inspections, we develop our own plans, routes, and requirements, and then organize reviews before issuing instructions for implementation. All materials in the unit have been removed; equipment and pipelines have been purged. The entire unit has been isolated using blind flanges. The inspection interval has been changed from 1 hour to 2 hours. Special inspection records have been compiled, and inspection routes have been established. Designated personnel are on duty, and handover meetings are conducted in accordance with standards.
