What should be done after identifying a fire source during the under floor fire drill?

After identifying a fire source during the underfloor fire drill, it is critical to prepare Halon and gloves. Halon is a fire suppression agent specifically designed to extinguish fires effectively, particularly in enclosed environments like aircraft. The use of Halon is vital since it can quickly suppress flames without leaving a residue that could harm sensitive aircraft systems. Wearing gloves is also important to ensure protection from heat and possible hazardous substances while handling firefighting equipment.

The presence of a fire in an aircraft, especially under the floor, requires immediate and appropriate action to mitigate the situation safely. The preparation of needed equipment, including Halon and protective gloves, is a crucial first step before any further actions are taken, such as notifying crew or passengers, as these steps can only be effectively managed once the firefighting measures are in place.
