We also use Automation for our plant safety with our employee safety. Supposedly if you have any restricted area where no person cannot wear shoes without, then we can put automation there. We can put an alarm or SMS notification there, so that if someone goes there without wearing shoes, then the system can notify them with SMS or the Alarm will sound. In this way we can set up automation for industry machinery, valves, pipes and much other equipment. Suppose that you have a machine whose capacity is 1000Pa pressure, we can setup such a form or message system so that, if any machine goes above 900Pa then the system can notify you with SMS or the Alarm will sound. We can do the same for many other machines, valves, pipes, Etc also , we can automate the temperature , Force and other things in the machine in this way.
So we can implement automation for safety purposes in our chemical industry in this way.
