Football Federation Australia is assisting active supporter groups using pyrotechnics at A-League games and is set to permit "safe" smoke-emitting devices in stadiums next season.

In what is understood to be a world first, a national federation could help supply fans with smoke-emitting devices and encourage use of legal pyrotechnics with the FFA determined to rejuvenate active support in the A-League.

The FFA has not wavered from its firm stance against the lighting of flares inside venues, which is illegal in Australia due to the extreme heat released and potential to cause serious burns. However, in helping fan groups use devices that release volumes of coloured smoke for approximately 90 seconds with limited or no heat, the FFA believes it can find a legal and safe alternative to flares.

Head of the A-League, Greg O'Rourke, is working to allow "safe smoke" devices into stadiums for next season pending approval from authorities.
