Which item is NOT used in the Seat fire drill procedure?

In the context of a seat fire drill procedure, certain items are essential for effectively managing and extinguishing a fire. An extinguisher powder, while commonly used in various fire suppression methods, is not typically part of the procedure specifically for dealing with seat fires during a drill.

Halons are effective agents for extinguishing fires without leaving a residue, making them suitable for protecting sensitive equipment and minimizing damage. Fire gloves are also vital, as they offer protection to personnel handling hot or potentially dangerous materials during the drill. Non-flammable liquids might be included for safety measures to prevent the risk of fire spreading, but extinguisher powder does not align with the direct procedures focused on seat fire scenarios.

Therefore, the exclusion of extinguisher powder indicates that it's not a component directly utilized in a seat fire drill procedure aimed at ensuring safe and efficient responses to such incidents.
