So far it's only large shops and large jobs that are starting to take it seriously, in my experience. Have those new OSHA rules finally taken effect? They've been delayed for years, and even if they have, OSHA no longer seems to make site visits.

I'm in Soviet Canuckistan but it's similar to the US, big contractors are starting to require it. It's also driven by insurance companies who offer lower premiums to companies who enforce safety rules on their jobs. I got out of construction a few years ago so it's probably more strict now.
