Interview today- OSHA questions?

I am interviewing for a position later today at a small hospital. The job includes responsibilities in the employee health department. They are asking that the candidate have knowledge of OSHA guidelines. I am familiar with Hazard Communication, PPE requirements and Chemical Hygiene from my work in the laboratory. Is there anything else that I need to know? I looked on the OSHA website but was unable to find what I was looking for. TIA
