Subpart 139.H -- Aerodrome rescue and firefighting services
Note: As a signatory to the Chicago Convention, Australia is obliged to require, as part of its domestic law, that certain classes of airport provide rescue and firefighting services of an adequate standard. (See generally section 9.2 of chapter 9 of Annex 14 to the Chicago Convention.) To satisfy that obligation, this Subpart requires operators of aerodromes that have scheduled international traffic, or specified levels of domestic passenger traffic, to provide those services, and sets out the standards that apply to such services. Aerodromes that are not obliged to provide an ARFFS may choose to do so, and this Subpart will apply to a service so provided until the operator gives reasonable notice that it will no longer provide such a service.
