First Aid Fire Extinguishers are the primary equipment used for immediate fire control during the incipient (initial) stage of a fire. They are universally referred to as Portable fire extinguishers because they are designed to be carried or moved easily to the fire location by a single person.

• Tenders: Options A, B, and D (Fire tenders, Foam tenders, and DCP tenders) refer to large, specialized firefighting vehicles or trucks operated by professional fire services. These are not considered "first aid" appliances but rather major fire suppression units.

Portable extinguishers are categorized based on the extinguishing agent they contain, such as Water, Foam, Dry Chemical Powder (DCP), or CO₂, and are essential for life safety and property protection in buildings.
