Who are the people wearing white work uniforms in the chemical plant?
Thread Content
In a chemical plant, people wearing blue, red, or gray work uniforms can be easily distinguished by which unit they belong to or what role they play; who are those wearing white work uniforms? What are they doing?
It seems like the top cover of the reactor has been opened to check/inspect something inside the reactor. White protective clothing is actually quite common.
That’s great; all the friends upstairs guessed correctly. These \"angels in white\" who work on the construction sites are the inspection and testing personnel from the engineering quality supervision station. Their job is to prevent accidents caused by defects in the vessel’s structure or failures in its performance under operating pressure, by means of inspections and tests.
Before each inspection, they don’t hesitate to \"get fully equipped,\" enduring the high temperatures, rust, and unpleasant odors inside the containers. They conduct various inspection methods such as ultrasonic testing, magnetic particle testing, penetrant testing, and radiographic testing to carry out a \"medical checkup\" of the pressure vessels, in order to identify any defects in the equipment. Ensure the safe operation of the device.
Another question: Since one has to enter pressure vessel equipment to work every time, why not wear a protective suit in a darker color? @huanghong @Zhang Yong_efD8q @Shutong @gugd @DeepSea
The people from the Quality Inspection Bureau brought this kind of equipment; ours is that gray one-piece dust-proof suit
Offshore engineering companies also use white one-piece work uniforms; they are uncomfortable to wear in summer, probably because white stands out quite a bit inside the modules (or ship cabins).
