This part of ISO 23269 provides performance specifications for emergency escape breathing devices (EEBD) required by regulation in Part D of chapter II-2 of the 1974 International Convention for the Safety of Life at Sea (SOLAS), as amended in 2000, and chapter 3 of the IMO International Code for Fire Safety Systems (FSS Code). These devices are intended to supply air or oxygen needed to escape from accommodation and machinery spaces with a hazardous atmosphere. They are not intended for use in fighting fires, entering oxygen-deficient voids or tanks, or to be worn by fire-fighters.
