Several restrictions will be imposed by the police for patrons attending the Inter-Secondary School Sports Association (ISSA) Boys' and Girls' Championships at the National Stadium.
The five day event starts on Tuesday.
The police say firearms, knives, ice picks, machetes, aerosol sprays, large coolers, glass bottles, lighters, frozen water or drinks, drugs, fire crackers, video recorders, alcohol and umbrellas with pointed tips will not be allowed inside the venue.
Additionally, smoking will not be permitted inside the venue.
Persons found in breach may be asked to leave the stadium.
The police say walk ways should be kept clear at all times in cases of emergency and there will be a no re-entry policy.
Licensed firearm holders are being advised to make alternative arrangements for the safekeeping of their firearms, as no provisions will be made at the venue or at the Stadium Police Station.
Patrons entering the stadium will be subject to search and vending will not be tolerated outside the designated areas.
