I agree with the previous response. First, OHN positions are very, very rare. When I was trying to get my foot in the door in Occ Health in the 90's, I faced the same problem. Everyone wanted experience, and you had to work so many thousands of hours to get certified, etc. etc. (When I got certified as a COHN-S, you had to have 4000 hours of time in.) You must really plot out your course, and build a resume and experience that will look enticing to an occupational health potential employer eventually. It takes commitment and dedication in order to get all the credentials you need. It is definitely not one of those things where you are able to just start working in occ. health. So, first get some ER or urgent care experience, as the previous nurse that replied said, and try to focus mainly on adult care. If you don't have 12 hour shifts in the ER, I would recommend becoming a per diem nurse and/or working through an agency. That is what I did in order to be available to work contract vacation relief shifts in Occ Health. Apply to any agency that ever gets any occupational health contracts in your area. Work contract shifts in as many places as possible. Then, pay for at least one certification course yourself, or have your hospital (if you continue to work for a hospital) pay for it as continuing education. Get certified in audiometry with a CAOHC certification. And/or get certified to give PFT's and do respirator fit testing. You might check out your employee health department in your hospital, that would be an excellent place to start picking up extra shifts. They would train you a bit, hopefully-especially as far as respirator fit testing-although only the hospital type. The real respirators used in industry are a different story. Or, if you don't mind taking a pay cut, check out any Concentra office for openings. Their pay is low, but they would likely train you free of charge. Also, any certification that you can get in urine drug testing and BAT testing would be great. All in all, in order to be a real "catch" for an employer you need all of those - BAT, DOT urine drug screen, CAOHC cert. and PFT/respirator cert. It is a long road, and the courses all cost about $ 500.00 each (approximately), but if Occ Health is really really what you want to do, then it is worth it down the road. Also, any studies you do re: ergonomics and anything you learn about your state's workers compensation laws, and CERTAINLY the basics of OSHA recordability re: on the job injuries will help, and will be eventually items you will need to know if you pursue this path. Good luck and keep building that resume a little at a time until you get there.
