RedLogix 2.1 Interestingly that article starts with a description of appallingly bad safety standards at a major petrochem site in the 1960's. Yet remarkably everything has changed in the 50 years since; the events he describes are pretty much unthinkable in a developed country today. In particular: One day, Sherman was standing in a room, leaning over a large pipe to check a filter, when an operator in a distant control room mistakenly turned a knob, sending hot, almond-smelling, liquid chlorinated hydrocarbons coursing through the pipe, drenching him I worked for decades in that control room, always aware that I could kill or main with a bad or unlucky decision. Yet the technology advanced dramatically, giving us tools and platforms that properly implemented, making incidents like the above orders of magnitude less likely. Organisations soon realised that investing in safety tech actually saved them cash, and in the past decade virtually every major new install, and many smaller ones, now has a substantial safety tech component.
