Any Boiler License Holders Out There?

I was talking with my uncle and my grandpa the other day. They both teach classes on and work with boiler operation and building maintenance. They said that generally, there are very few Mac users in this field. Well, are they right?

My father has his boiler operators license and is in the building maintenance field. He uses Macs.
