I have traveled across many sketchy floors. I mean if you see a shot you gotta get it. Don be dumb tho, make sure someone knows what your plan is so if it falls in they know to look for you some where.
Other then that that advice in this thread is solid. Dont underestimate it as getting you out with little equipment can be a bad situation. I carry 100' of rope & a roll of Duct tape when I go on big explores.
Ceilings get the same treatment just you dont walk on them. Look up as you go up the to new floors. You can see if the roof/ceiling is going to come down, the floor is weak ect.
Common sense is key here and it can save you and your friends lives.
