Qantas says it is investigating the use of alternative fire retardants after a foam spill at one of its Brisbane Airport maintenance hangars on Sunday. The hangar’s sprinkler system released a reported 22,000 litres of PFOA fire retardant foam, some of which entered a nearby creek. The spill saw the Queensland Government issue a public warning to not eat seafood caught near the airport. The Queensland Government banned the use of PFOA foam last year, but Brisbane Airport is covered by federal government regulations as it is on Commonwealth-owned land. “While the foam we use in Brisbane meets our current requirements under federal safety regulations, we have been working through a process to replace it with a type that meets the Queensland Government’s updated requirements,” Qantas said Thursday. “There are few fire retardant products available around the world that meet aviation standards for use in an aircraft hangar. We are working as quickly as possible to replace it,” Qantas said. The federal government, meanwhile, says it is investigating transitional arrangements to firefighting foams that do not include PFAS substances such as PFOA and PFOS.<br/>
