Where is the water fire extinguisher located on the ERJ 175 aircraft?

The water fire extinguisher on the ERJ 175 aircraft is strategically placed in the AFT Dog House on the 76-passenger version. This location is chosen for its accessibility, allowing crew members to quickly retrieve the extinguisher during an emergency when fires may occur in the rear section of the aircraft, where the lavatories and galley are located.

Positioning the extinguisher in the AFT Dog House ensures that it is available for use in the commonly affected areas during a fire event, while also being out of the way of passenger traffic and not obstructing other safety equipment. This placement reflects safety protocols that emphasize rapid access to firefighting equipment in critical situations.

The other potential locations, such as the cockpit, near the galley, or in an overhead bin, would either hinder quick access during emergencies or are not designated for water fire extinguishers specifically, which is why they are not the correct choices.
