Fire Protection Flashcards
How does the lavatory fire extinguisher work?
A halo bottle is located in the trash bin. It is sealed with a heat sensitive plug. Heat from a fire will burn through the plug and release the halo into the trash bin.
Is there a way to test the smoke detector in the lavatory?
Yes. A pushbutton is located on the detector mounted on the ceiling. When pressed, the SMOKE AFT LAV warning message illuminates on ED1
