I'm a controls engineer, and I deal with people like this all the time while developing safety systems for industrial automation. "It's safe if you don't do something stupid." "Those [generic components] should be reliable enough, they often last for years." "It's a good thing you didn't see the chainsaw work I did at my house last weekend" "I'd feel perfectly comfortable with that machine if I was going to stand there" "We've always done it that way" When you're getting paid hundreds of thousands of dollars to deliver a machine, or using that machine to make millions of dollars worth of product, fighting about a $200 safety relay or $800 light curtain is not the same risk analysis as lighting fireworks in your backyard. Because it's not about your risk, it's about the risk of the new high school grad with no options except a $15/hr factory position, who has neither the knowledge nor the freedom to mitigate that risk.
