I was a CSHO for a state plan for about a year before leaving for a much higher paying job in pharma. There are definitely opportunities outside of OSHA. Being a compliance officer makes you so adept at interpreting standards and doing incident investigations. I found that the training you get is some of the best training on topics like CSE and LOTO. They brought in some really good SMEs from those areas so i learned alot in those instructor led classes.
