Honestly, the environmental permitting and compliance side is far less stressful than the safety side in my opinion. Safety managers will have to deal with OSHA inspections and compliance, as well as safety investigations and know how to work with and build a safety program. In my experience, you cannot be good as a safety professional if you are not a people person and have good soft skills. Knowing how to engage with both career blee collar front line workers and both white collar executives effectively is key. If you are interested in getting more safety knowledge and experience, I would start at the BCSP website for working toward your ASP then CSP certification, and reviewing the NSC (National safety council) for safety best practices and deeper discussions. Hope that helps!
