G'day lizardjasper,
There are a few of ways to become involved in working with elapids, but for most people who don't know somebody who is experienced enough to teach them appropriate techniques, then attending a reputable course is the best way to go.
Most zoo's and wildlife parks have their own requirements with regards to handling elapids - some turn a blind eye and hope for the best with new employees, some have very strict guidelines and others prefer to train their staff "in-house".
