Which fire extinguishing agent is the least effective for use in an aircraft fire?
Refer to figure.
Firstly, "Powder extinguishers" are effective on various types of fires, including electrical and flammable liquids. However, the powder can be abrasive and corrosive, potentially causing damage to aircraft components and systems. It can also impair visibility and be difficult to clean up.
Secondly, "Halon" is highly effective for aircraft fires as it quickly extinguishes flames without leaving residue. It is safe for use on electrical fires and sensitive equipment, making it suitable for aircraft use.
Thirdly, "Foam" is effective for fuel fires and provides a cooling effect that helps prevent re-ignition. It is commonly used in aviation firefighting and can be suitable for aircraft fires, especially those involving flammable liquids.
Finally, "Water" is generally the least suitable for aircraft fires because it is ineffective on fuel and electrical fires, which are common in aircraft. Water can also cause damage to electrical systems and avionics. Its limited effectiveness and potential for causing further damage make it a poor choice for aircraft fires.
