Interesting that she was only charged with negligence and fined. Almost like a workplace safety violation. Any bets it would have been a murder charge here?

It does bring up the idea of safety issues around bondage rigging and a tops ability to get the sub out in a hurry (or at least into a safe position.) Regardless of how else he was bound if she could have gotten him on the floor and the tension off of his neck he probably would have been OK>

Rope (especially under tension) is easy to cut with a sharp knife or safety shears) One of those auto rescue tools with a seatbelt cutter is also a handy thing to have around. If chain is used there are also quick release snap shackles that can be tripped while under tension.

If nothing else this demonstrates the importance of playing with a Domme who is skilled in the areas of play you want to explore. When it comes to bondage it's about the ability to foresee problems and having a plan to deal with them.

Unfortunately, I have found over the years that there are some Pro Dommes who are relatively unskilled when it comes to more elaborate or intense bondage.

I'm curious as to how much contingency planning Dommes engage in when planning a session? Have you ever had a sub pass out or suffer some other medical emergency?
