Yes, I imagine that safety would be an ongoing concern and at the top of her daily agenda. You would have to keep up on current regulations and probably confer with company counsel from time to time to know exactly what’s expected of you to remain in compliance.
For that reason alone, I think that it would be quite a stressful job. It's not one that I would want, personally. I have my hands full just making sure that I am complying with everything that my company expects of me, let alone making sure that a coworker doesn’t needlessly stumble down the stairs.
