FIRE SUPPRESSION SYSTEMS ASSOCIATION Comments on Annex XV Restriction Report on per- and polyfluoroalkyl substances (PFAS) The Fire Suppression Systems Association (FSSA, www.fssa.net) is a membership organisation whose more than 150 members include the manufacturers and designer-installers of automatic special hazard fire suppression systems.

Belgium does not agree due to political reasons based on the political problem in Antwerp area by the legacy PFAS.
