Physical Danger
While there aren't a lot of physical dangers commonly associated with what's essentially doing paper work and talking on the phone for a living, some people seem particularly skilled at finding ways to injure themselves regardless of circumstances.
Without HR safety guidelines, your professional setup is in your hands, which makes it your responsibility to make sure that the mini-fridge in your office isn't plugged into a frayed extension cord (and the same goes for your massage chair and electric blanket).
Don't text and drive no matter how important the client is, watch out for paper cuts, and sit with good posture to pretty much guarantee that your job will have nothing to do with your next injury.
