Reply to Dealing with fights at gigs?

A mate and I could be doing a little club evening in a month or two, focused towards the DnB and Dub lovers out there.

We were believeing that a mixture of high tempo 'agressive' tunes and alcohol could spark the odd scuffle. Its not a huge concern of ours but definitely got us believeing... Does anybody have any tips on how to deal with this sort of thing. Obviously these things are ultimately inevitable, but once its all kicked off (large or small) how would you deal with it?

I've heard of DJ's in the past simply stopping the music if a fight breaks out and announcing over the mic that it won't start again until the fight stops. This maybe acceptable for a DJ with a large fan base/lots of experience/respect etc but what about DJs that are just starting out?

Or should you simply trust the abilities of the security at the venue and just focus on the music.

Cheers.
