Security

Paid security should conform to BS 7499:2007

An example of the instructions given to security staff: BJC 2008 Security Procedure

BJC 2010 hired a security company that specialised in festivals (rather than night clubs or building sites, for example). This meant that they were more familiar with the atmosphere expected at a BJC. They understood how to be understated and friendly, they were comfortable with "alternative" people, and familiar with the kind of teen drinking / drug taking problems that need to be resolved sensitively but firmly and quickly.

Some security situations may require a team member to make a decision. If a paying customer (or trader) is found starting a fight, harassing people or endangering the convention with illegal behaviour, you have to decide whether to throw them off site.

In this case you are legally entitled to eject them. It may be wise to have an explicit policy on this beforehand, making it clear that refunds will not be given.
