Discuss the basic requirements for each of the following "NAVOSH" (Navy Occupational Safety & Health) Programs:

Respiratory Protection
Hearing Conservation
Sight Conservation
Personal Protective Egui

Respiratory  Protection: shall be established as per OPNAVINST 5100.23D. Personnel shall be fit tested and medically qualified to wear the respirator being issued.
Hearing Conservation: the program shall identify potentially hazardous noise levels to prevent occupational hearing loss. the use of personnel hearing protection devices are used as a protective measure. periodic hearing test shall be conducted.
Sight Conservation: navy policy requires navy personnel exposed to eye hazardous areas are provided adequate eye protection at government expense. any person entering a posted eye hazard area shall be required to wear eye protection.
Personal Protective Equipment: PPE is employed to reduce or eliminate personal exposure to hazards. PPE is simply a last line of defense. all personnel will be familiar with the use of PPE.
Define the following terms as they apply to the "NATOPS" (Naval Air Training and Operating Procedures Standardization) and "MIM's" (Maintenance Instruction Manuals):

Warning: failure to follow an indicated action could result in serious personal injury or harm.
Caution: failure to follow an indicated action could result in serious equipment damage.
Shall: means a procedure that is mandatory.
Should: means procedure is recommened.
May: means procedure is optional.
Will: indicates futurity and never indicates any degree of requirment for application of procedure.
Discuss the following as they apply to hangar deck safety:

Portable Fire Extinguisher
Fire Lanes
Smoking/Open Flame
Aircraft Ground
Emergency Eye wash/shower Sations
Portable Fire Extinguisher: classified according to the type of fire they are designed to extinguish. they shall be located on normal paths of travel as to be readily and immediately available in the event of a fire.
Fire Lanes: lanes suitable for firefighting equipment shall be clearly marked and kept clear.
Smoking/Open Flame: smoking or open flames shall not be permitted within 50 ft of parked aircraft, hangers, etc.
Aircraft Ground: aircraft shall be electrically grounded during all maintenance evolutions. tie down chains do not provide adequate grounding and shall not be used to ground aircraft.
Emergency Eye wash/shower Staions: are located where water is not readily available.
Discuss "HERO" (Hazards of Electromagnetic Radiation to Ordnance) conditions, and the safety precautions associated with handling "CAD's" (Cartridge Actuated Devices)
HERO is concerned with the accidental actuation of "EED's" (electroexplosive devices) or other wise activating eletrically initiated ordnance do to radio frequency electromagnetic fields. CAD's should be treated as explosives.
Discuss the safety precautions associated with Liquid Oxygen (LOX)
do not service lox converters in an unsheltered area during inclement weather. moisture will freeze immediatly on contact. 2 quilified personnel present when draining converters. Sevice MIL-O-27210 Type II LOX only. always wear goggles/face shield, coated apron, cuffless coveralls, rubber coated apron, clean-dry gloves, and LOX type boots.
Discuss safety precautions associated with gaseous oxygen
gaseous oxygen is extremely hazardous when used in the presence or comes into contact with readily combustible material. use MIL 27210 Type I only in aircraft gaseous oxygen systems.
Discuss the safety precautions that must be observed during fueling operations
do not operate any electrical or electronics equipment on the aircraft except as specified. ground the fuel supply unit and aircraft. no smoking around the aircraft while fueling. check the main gear inboard doors are closed before fueling.
Discuss the safety precautions that must be observed for an open fuel cell
have area approved & identify the area as an open fuel cell area. area must be approved by the MO, Fire Marshall, & Safety Officer. an additional 50 ft may be required if exhaust purge is used. meet all requirements of the national electrical code class I, Div I, Group D hazard locations. all areas shall have 2 approved fully charged fire extinguishers. adjacent aircraft shall not be allowed to operate under their own power within 100 ft of the repair area.
Discuss the following safety precautions for lifting an aircraft:

Wing and Fuselage
Nose and Main
Wing and Fuselage: the entire aircraft may be lifted at the wing and aft fuselage jack points. jack on level surface away from the wind. a tail support should be installed as a precation as the aircraft center of gravity moves aft when jacked.
Nose and Main: do not jack fuselage station 218.0 (forward fuselage jack point) in conjunction with the fuselage station 995.0 (aft fuselage jack point). severe structual damage will occur if the wing jacks are released while the jacks are raised at both fuselage jack points.
Describe the general characteristics of the C-9B/DC-9 aircraft

manufactured by McDonnel Douglas
transport personnel & cargo
max takeoff weight: 110,000
max landing gross weight: 99,000
119.3 ft long, 93.3 ft wide
27.5 ft tail height


State the primary and secondary emergency exits


Ground Egress: the forward, service, and aft entrances are primary exits. overwing, pilot & copliot clear view windows are secondary exits.
Ditching Situation: overwing exits are primary exits. pilot & copilot clear view windows, forward, and service door entrances are secondary exits.

Describe the following C-9B/DC-9 aircraft "SECO" (Seat and Equipment Configuration Outlines):

SECO "A": 3 HCU-6/E pallets w/"VIP" (very important person) seats and 47 coach seats.
SECO "C": 2 HCU-6/E pallets and 65 coach seats.
SECO "D": 90 coach seats.
SECO "G": 3 HCU-6/E pallets and 45 coach seats.
SECO "H": special mission 7 HCU-6/E pallets and 7 coach seats.
Discuss the history of the C-9B/DC-9 aircraft
1970 NAVAIR undertook concept to integrate manpower & equipment to augment duty counterparts in time of war.  
Define the following acronyms:

IFF: identify friend or foe. allows friendly aircraft to identify itself automatically.
ADF: automatic direction finding. 2 identical ADF systems are installed on the aircraft. each system provides automatic direction-finding capability.
TACAN: tactical air navigation. uses a bearing determining system to determine aircraft position and disatance up to 300 nm.
TCAS: traffic collision avoidence system. tells the exact position or location of other aircraft traffic.
FMS: flight management system. tells your position, fuel burn, rate of fuel consumption, guides the auto pilot, gives time to way-point, fuel required and airspeed.
GPS: global positioning system. works in conjunction with 3 global satalites to provide exact location in longitude, latitude and altitude. acurate within 3 to 6 meters.
INS: intertia navigation system. a navigation system that provides aviation and guidance data without reference to ground-based navigation aids.
VOR: very-high frequency omni directional range station. a ground-based electronic navigation aid to transmitting very high frequency navigation signals, 360 degrees in an azimuth, oriented from magnetic north.
ILS: instrument landing system. a precision approach system that provides alignment and descent guidence to the pilot.
GPWS: ground proximity warning system. provides the pilot with a visual and aural warning of potentially hazardous flight paths relative to the terrain.
Discuss the importance of the aircraft static dissipation system
static discharges are installed at the extremities of the airplane to dissipate static electricity with a minimum amount of radio interference. which include wing tips, elevator, horizantal stabilizer, vertical stabalizer, and tailcone.
State the purpose of the C-9B/DC-9 electrical power supply system as stated in the NATOPS flight manual 

the aircraft's engine-driven generators are the main electric power source. the APU generator is used for electric power for engine starting, air-conditioning, and other electric needs while on the ground, and as a backup power source in flight.
