ENGINE FIRE EXTINGUISHING: FIRE EXTINGUISHING AGENTS ARE THOSE CHEMICAL THAT ARE INJECTED INTO A COMPARTMENT OR AREA TO ENTINGUISH A FIRE.THOSE AGENTS WORK BY EITHER DISPLACING THE OXYGEN OR CHEMICALLY COMBINING WITH THE OXYGEN TO PREVENT COMBUSTION.SOME ADDITIONAL EXTINGUISHNG EFFECT CAN OCCUR BY THE LOW TEMPERATURE AT WHICH THE AGENTS ARE DISCHARGED.

COMMONLY USED AGENTS ARE: CO2,FREON(CHLORINATED CARBON) HALON 1301 (MONO BROMOTRIFLUOROMETHANE –CF3Br), NITROGEN(N2) Halon 1301 and FREON ARE IN A LIQUID STATE WHEN UNDER PRESURE BUT BECOME GASEOUS WHEN RELEASED TO ATMOSPHERIC PRESSURE. MOST MODERN AIRCRAFT USE HALON 1301 AS EXTINGUISHING AGENT. *CO2 IS LIMITED TO RECIPROCATING ENGINE POWERED TRANSPORTS.

TWO CLASSIFICATION OF FIRE EXTINGUISHING AGENTS: 1.CONVENTIONAL SYSTEM: IT IS NORMALLY FOUND IN PISTON ENGINES.IT USES CO2 AS EXTINGUISHING AGENT.IT USES PERFORATED RING AND DISTRIBUTOR NOZZLE DISCHARGE ARRANGEMENT WHEN THE SYSTEM IS ACTIVATED. 2.HIGH RATE OF DISCHARGE SYSTEM. IT USES FREON OR HALON 1301 AND THE SPHRICAL BOTTLES ACTUATED BY EXPLOSIVE CARTRIDGES. THE DISCHARGE TUBES ARE CONFIGURED TO ALLOW A RAPID RELEASE OF AGENT INTO THE FIRE AREA AND FLOOD THE COMPARTMENT.

SHOP SAFETY 1.KEEPING HANGARS,SHOP AND THE FLIGHT LINE ORDERLY AND CLEAN IS SAFETY. 2.THE SHIFT PERSONNEL SHOULD STORE PERSONAL TOOLS,ROLLAWAY BOXES,ALL WORKSTANDS,HOSES,ELECTRICAL CORDS HOISTS CRATES AND BOXES. 3.SIGNGS SHOULD BE POSTED AT CRITICAL POINTS INDICATING DANGEROUS EQUIPMENT. 4.SAFETY LANES,WALKWAYS AND FIRELANES SHOULD BE PAINTED. 5.SAFETY MEASURES TO PREVENT ACCIDENT.

ELECTRICAL SAFETY: WHEN ELECTRICITY IS APPLIED TO HUMANBODY IT CAN CREATE SEVERE BURNS. 1.ELECTRICIAN SHOULD WEAR PROPER SAFETY EQUIPMENT TO PROTECT HIM. 2.THE USE OF RUBBER CLOVES,SAFETY GLASSES, RUBBER OR GROUDED SAFETY MATS CONTRIBUTE TO PHYSIOLOGICAL SAFETY. 3.OVERCONFIDENCE SHOULD BE AVOIDED. 4.SHOULD HAVE ADEQUATE KNOWLEDGE.

FIRE SAFETY: THE GREATER THE CURRENT FLOWS,GREATER HEAT IS GENERATED.WHEN THE HEAT IS HIGH IT CAN MELT THIS HEAT CAN BECOME SO GREAT THAT METALS CAN MELT,LIQUIDS,VAPORIZE AND FLAMMABLE SUBSTANCE IGNITES. KEEP THE AREA AROUND ELECTRICAL WORK CLEAN,UNCLUTTERED,AND FREE OF ALL UNNCESSARY FLAMMABLE SUBSTANCES.

CHECKLISTS. USE CHECKLIST WHEN PERFORMING AN INSPECTION THE CHECK LIST SHOULD INCLUDE: 1.FUSELAGE AND HULL GROUP 2.CABIN AND COCKPIT GROUP 3.ENGINE AND NACELLE GROUP 4.LANDING GEAR GROUP 5.WING AND CENTER SECTION. 6.EMPENNAGE GROUP 7.PROPELLER GROUP 8.COMMUNICATION AND NAVIGATION GROUP 9.MISCELANEOUS
