What is the primary function of the items in an A/O kit?

The primary function of the items in an A/O kit is fire suppression. A/O kits, which stand for Aqueous Film Forming Foam (AFFF) Ocean kits, contain materials specifically designed to combat fires, especially those involving flammable liquids. The key components of these kits typically include foam agents that can effectively smother flames and suppress fire by creating a barrier that prevents oxygen from reaching the burning substance. This makes them essential in environments where flammable materials are present, ensuring safety and minimizing the risk of fire-related accidents.

In contrast, the other options refer to different functionalities: emergency repair kits typically contain tools and materials for fixing equipment or structures; water removal items focus on pumping or absorbing water; and fuel storage items are designed to safely hold fuels and may not be equipped for fire suppression. Thus, these functions differ significantly from the primary purpose of fire suppression associated with A/O kits.
