c. Move ground support equipment away so that fire fighting equipment will not be hampered.

e. When available agent is expended and/or the fire is,but of control, evacuate the area because of the danger of explosion.

Oxygen Fires.

Oxygen can cause spontaneous ignition and explosions when It comes in contact with flammable substances. ire aided by oxygen will burn intensly and spread rapidly. CO2 or DCP (dry chemical powder) should be applied to slow the progress of these fires. However, effective extinguleh-ing of oxygen-supplied fires generally require foam. Sourceser cent oxygen in the aircraft are the bottles in the nose wheel or chine area.

Scratches and dents' reduce structural strength and Impair aircraft performance. Damage caused by careless walking or handling of tools can require extensive repairs.

Foreign Object Damage.

object damage ia an ever present hazard to the operation

of gas turbine engines. It is the responsibility of all maintenance personnel to conscientiously adhere to and follow preventive procedures and policies to eliminate ingestion of foreign objects by gas turbine engines* Several areas of concern are parking and storage areas, maintenance areas and procedures, engine installation and engine ground operation. Frequent and periodic Inspection of engine nacelles. Inlet duets and storage areas Is recommended. When required, careful cleaning of areas should bo accomplished. All maintenance personnel mast exorcise extreme care while performing maintenance procedures in and around the aircraft to prevent foreign object daroage'to the two turbojet engines. The greater sfse of the engines creates greater suction pressures and ma oh larger suction areas. These higher suction pressures enable the engines to pull objects from greater distances into the intake ducts or the engine

nacelle areas and on Into the engines' compreaior sections. Objecte may be picked up from the deck area* or from other areas which are directly or Indirectly open to the engine nacelle and inlet duct. Therefore, it Is mandatory that personnel performing maintenance In and around theaccount for all tools, hardware and components after all maintenance procedures and operations.

Duct plugs and dust excluders are required to reduce foreign object accumulation. (See Figure )

Parking and storage areas should be Inspected for foreign objects. Such material shall be removed with brooms, sweepers or other suitable equipment.

General maintenance and structural repair procedures can coo-| tribute foreign materials for ingestion by gas turbine engines. The following procedures are designed to reduce these materials:

effort should be made toareas as clean as posslbli
