Increased Complexity = Specialization. While it’s not exactly E=MC2, it is nonetheless true. The more complex something becomes, the more likely we are to need someone that specializes in it. So it is with emergency equipment design, specification, installation and maintenance.
Urban legend has it that the first emergency eyewash was designed by a concerned plant supervisor who fashioned an eyewash out of spare drinking fountain bubblers. In my mind, that’s closely akin to trying to halt a four-alarm blaze with a garden hose. But everything has to start somewhere.
