Do you know while working in the chemical industry you are in constant danger of hazardous spray outs or leakages? Do you know these can be dangerous for not only your plant but for personnel too? If you know all these facts, so, why are you playing with fire just to save some bucks? You should buy and install Flange Guards to be on the safe side. Do you know ignoring them is like skating on thin ice, which is not safe in any manner? So, stop doing it right away, especially when you have the effective solution to deal with the problem that too in your budget.
