To add, you said mainly to see the instrumentation, that is to say, is the process operator, now the chemical plant due to the use of new processes, new equipment, new materials, new technologies and other advances in the operating environment has been a very big improvement in the intensity of labor is also a substantial reduction in the ability to work in such a factory is a good thing. But to really do away with the hazards of their own bodies, but also have to plant managers at all levels to improve safety, environmental protection management and control, to ensure the timely detection and rectification of hidden dangers, to eliminate accidents, at the same time, all employees must understand the plant's various chemicals and harmful factors of the production unit, know the relevant protective measures, the correct use of labor protection supplies and emergency rescue apparatus, only these are done, the Only these are done well, can protect you from accidental injury.
Harmful factors in a chemical plant exist objectively, and no harm has occurred because these harmful factors have been effectively controlled, not that the danger does not exist. Therefore, can not be measured by the surface of the work task, in addition to the completion of the daily operation of the task, there are many jobs to do, such as checking, testing, checking the process parameters, whether there is anomaly, troubleshooting, and so on the situation. Personal opinion, I hope these can help you.
