I'm sorry to hear of this accident, Rickey, and hope that the injured dancer is
going to be okay. I cannot speak to the other questions you raise, but I will
use your unfortunate incident as an opportunity to encourage callers to carry
liability insurance.
Caller's liability insurance offers some protection in case you get sued as the
result of an accident. (It is also increasinly necessary to show such coverage
as a condition of renting many halls.) It is available at minimal cost through
Callerlab, the national association of square dance callers, and members of the
Lloyd Shaw Foundation and/or Country Dance and Song Society are eligible to
purchase it. You can find an overview of the CDSS arrangements here;
