Zitsulo zamsewu zonyamula zitsulo zokhala ndi malata Crowd Control Barrier (zomwe zimadziwikanso kuti zotchinga oyenda pansi ndi zotchingira anthu) ndi zopepuka komanso zoyenera kuteteza anthu ku zoopsa zomwe zimazungulira malo omanga.Zotchingazi ndizodziwikanso kwambiri pamakampani opanga zochitika chifukwa zimagwira ntchito ngati chotchinga chakuthupi komanso m'malingaliro ndipo ndi njira yabwino yowongolera oyenda pansi mosatekeseka polemba bwino njira zapansi.Pamene zotchinga za Crowd Control zitsekedwa, ogwira ntchito zachitetezo amatha kupanga mizere ya zotchinga zomwe zimakhala zovuta kwambiri kulowa.Izi zili choncho chifukwa zotchinga zowongolera khamu zikalumikizidwa, zimakhala zamphamvu ndipo sizingagwetsedwe mosavuta.Miyendo yokhazikika ya Offset imawonjezera kukhazikika ndi mphamvu ya chotchinga ndikupangitsa kuti ikhale yosasunthika mosavuta.Zopingazo zimapangidwa ndi mapeto a malata omwe amateteza ku dzimbiri ndipo amapezeka mumitundu yowoneka bwino (lalanje kapena yofiira) - izi zimabweretsa ndalama zowonjezera zowonjezera ufa.

Ma Crowd Control Barriers ndiwofulumira komanso osavuta kuyika pamalo omanga kapena zochitika.Amapangidwa kuti azilumikizana ndi chotchinga chotsatira pogwiritsa ntchito ndowe yokhazikika ndi lupu kumbali zonse.Palibe ma coupler owonjezera omwe amafunikira kuti agwirizane ndi zotchinga pamodzi.Zotchinga zosunthika ndizosavuta kuziyika, kutanthauza kuti zitha kusunthidwa kuchokera kutsamba kupita kumalo.Choncho, amatha kumangidwa ndi kutengedwa kuchokera kumalo kupita kumalo.
