Physical Danger
If you have others doing the actual rigging and whatnot for you, there's very little physical danger to this job—save for the occasional brawl between the roadies. If, however, you're also taking on the role of lighting technician in addition to your design work, you might end up on a tall ladder, contorted in a way that doesn't feel comfortable or safe. That has danger written all over it, both for you and anyone passing by below.
