One of my work duties is to give safety training on the principles of electrostatic safety; ESD training we call it. The group of people who go through my training are new employees. These folks come from all walks of life with education ranging from high school/GED to BS chemists & engineers to PhD chemists. In order to be compliant with OSHA and with what we understand to be best practices, we give personnel who will be working with chemicals extensive training in all of the customary environmental, health and safety areas.
I have instructed perhaps 80 to 100 people in the last 6 years. At the beginning of each session I query the group for their backgrounds and ask if it includes any electricity or electronics study or hobbies. With the exception of two electricians in the group, this survey has turned up a resounding zero positive responses.
Admittedly, there could be some selection bias here. It could be that people with electrical knowledge do not end up in the chemical industry. This agrees with my informal observations. But I’m not referring to experts in the electrical field. I refer to people who recall having ever heard of Ohm’s law. One might have guessed that the science requirements for high school graduation may have included rudimentary electrical concepts. One might have further suspected that hobby electronics could have occupied the earlier years of a few attendees. Evidently not. And it does not appear that parents have been very influential in this matter either...I messed around a lot with electronics when I was a pre-teen, had a lot of fun with electronics kits. (Incidentally, Snap Circuits are a pretty cool educational tool for kids.)
