I don't think it needs to be one major event. If I remember history correctly, there wasn't one boiler explosion that caused us to start regulating who was allowed to design boilers. It's just that as boilers became more and more popular at the end of the 19th century, people started being maimed and killed more often, and at some point we just as a society decided enough was enough. |
