if you do get tapped for a SEF deployment, they have in the past attempted to put you at a location with your qual'd aircraft so you can continue to fly. If you are an 11HXX (RW only), you're excluded from consideration for safety deployments since the career field is critically manned and ops tempo is so high. Your MAJCOM manages the safety deployment buckets and tasks wings as appropriate to fill the requirements.
I spent 1 yr as the SQ FSO, 1 yr as WG FSO, 1 yr at new duty station as SQ ADFSO (I was Chief of Training at the time), and 1.5 years as the WG Chief of Flight Safety.
I dig safety. I have done 2 Class A SIBs (one as the Pilot Member, one as Investigating officer) and 2 Class B investigations as SIO. And of course too many to count Class C, D, and E investigations at my wings. If AFSEC was hiring right now on the GS side, I would be there in a heartbeat.
Safety's not for everyone, and I'd ask you not to half-ass it if you do get the stink on you. It's something I care deeply about - I've lost several friends and family members over the years, and almost lost several others.
