Practice appropriate spotting techniques.

Make sure that everyone is involved when someone is being lifted off the ground, and appoint one person to focus on spotting the head and neck of the lifted participant.
 

It is very important that any lifted participant say that they choose to be lifted.
 

Also, only allow lifting when you feel that there are enough people on both sides to do so safely.
 

You are a great spotter. Get in and be part of the team.
