Crowd control is the controlling of a crowd, to prevent the outbreak of disorder and prevention of possible riot. Examples are at soccer matches, when a sale of goods has attracted an excess of customers, refugee control, or mass decontamination and quarantine situations (disease outbreaks, bitterer attacks, etc.). It calls for gentler tactics than riot control. Materials such as stanchions, crowd control barriers, fences and decals painted on the ground can be used to direct a crowd. Keeping the crowd comfortable and relaxed is also essential, so things like awnings, cooling fans (in hot weather), and entertainment are sometimes used as well. For controlling riots and demonstrations, see riot control.
Specific products that are used to implement line management and public guidance in high traffic areas include retractable belt systems (which incorporate a stanchion post and the retractable tape) and wall mount systems (also incorporating a retractable belt but are surface mounted). Post and rope systems are also popular, especially in banks and theaters crowd controller is also another name for a bouncer or doorman.
