Washington State has Labor & Industries - our version of workers comp. Our premiums are about 25K for 12 employees. I do believe safety programs work, but L&I is way over the top. Two examples:
They made an ergonomics law a few years ago that had such stringent requirements for things like repetitive movements that the cost to implement the law would have been more than most small companies could afford. L&I hired lots of extra staff to enforce it (they like surprise visits). Then the law was repealed. L&I still has lots of extra staff - no layoffs there!
Last year they made a "heat stress" rule, that says if it's over 75degrees, you have to provide x amount of water per employee. No problem, all our outside guys have their own 2 gallon thermojugs. If it's over 80 degrees, employees can take a break when ever they like for as long as they like, until they feel cooler, or a mandatory 15 minutes out of each hour. The employer also has to provide them with a shady place with a fan (or air conditioning) to cool off. None of the studies that I've seen justify L&I spending the $ to hire / implement all these new rules, but no one will stop them.
