101.1 Describe the basic requirements for each of the following Navy Occupational Safety and Health (NAVOSH) programs:

A) Respiratory Protection Program

A program which identifies Employees as requiring respirator protection equipment due to the nature of their work or job.

1)  Personnel, such as employees, inspectors and visitors who must enter an area where the use of respirators for 15 minutes or less, shall be provided and use the appropriate respirator equipment.

 These provisions do not apply to contractors who are responsible for their own respirator protection.
B)  Hearing Conservation Program
A program which surveys and identifies potentially hazardous noise levels and personnel at risk.

1)  Environments that contain or equipment that produces potentially hazardous noise levels shall whenever it is technology and economically feasible, be modified to reduce the noise level to acceptable levels.

2)  Periodic hearing testing shall be conducted to monitor the effectiveness of the hearing conservation program.

3)  Education of individuals, their supervisors and people providing hearing conservation services to these individuals is vital to the overall success of hearing conservation program.

C)  Sight Conservation Program
A program which surveys all activity work areas equipment and processes to determine which are eye hazards, which personnel require eye protection and what type of protection is required.

1)  In addition the common eye hazards the survey shall also consider the eye hazard associated with exposure to various forms of electromagnetic radiation.

2)  There shall be written certification that the hazard assessments have been made, shall identify the name of the person making the certification, date of the hazard assessment, and shall identify all areas designated as eye hazard.

3)  All eye hazard areas shall have the appropriate warning signs posted.

4)  Eye wash stations shall be provided in all areas where any employee may be exposed to corrosive materials.

5)  Any employee with 20/200(corrected) in one eye shall be considered visually impaired.

a)  And not assigned duties, which would present a hazard to his/her remaining eye. Required wearing eye protection to protect their remaining sight even if they do not work in eye hazard areas.

D)  Personal Protective Equipment (PPE)
A program which assess all workplaces to determined if hazards are present that necessitate the use of Personal Protective Equipment.

1)  If such hazards are present, or likely to be present, the following actions shall be accomplished.

a)  Verify that the workplace hazard assessment has been performed through a written certification that  identifies the workplace evaluated, the person certifying that the evaluation has been performed, the date's) of assessment, and which identifies the document as a certification of hazard assessment.

b)  Select and have each affected employee use the types of PPE that will protect them from the hazards  identified in the hazard assessment.

c)  Communicate selection decisions to each affected employee.

101.2    Identify the F/A-18 danger areas.

A)  Flammable liquids, compressed gasses .- areas including hydraulic reservoirs, fuel tanks, nitrogen charge struts, high pressure accumulators

B)  Canopy, seat and DFIRS explosive devices- many explosive devices are located throughout the airframe which have rocket motors, initiators and thrusters also controls that require special handling.

C)  Airframe and external stores-external fuel tanks, vertical ejection racks missiles launchers and conventional /nuclear weapons loaded on the wing or fuselage centerline pylons may be ejected. The area near those devices must be considered hazardous.

D)  Engine- danger areas resulting from engine operation are related to exhaust velocity and temperature, air intakes and high noise levels.

E)  Radar antenna- operation of the radar makes this a radiation hazard to personnel.

F)  APU exhaust - extreme caution should be used during aircraft start up this hazard area presents a high temperature danger.

101.3   Identify the minimum safe distance safe distances from turning aircraft intakes/exhaust at the following  power settings: (Note: difference in the exhaust safe distance is due to first being temperature safe distance second being velocity safe distance)

A)  Idle - 9 feet radius intake / 115-155 feet from exhaust

B)  MILITARY - 25 feet radius from intake / 325-725 feet from exhaust

C)  MAXIMUM - 25 feet radius from intake / 850-925 feet from exhaust

101.4   State the purpose and identify the location of the aircraft STEP, NO STEP areas:

Areas to avoid are your leading edge flaps, Trailing edge flaps, horizontal stabilators, ailerons, and radome surfaces. Areas that are designated, as walkways will have a non-skid on the surface also the wings themselves are considered walkways.

1)  Protective shoe covering should always be used worn when walking on aircraft.

2)  To avoid in damaging the composite material through out the aircraft structure extreme caution should be used with toolboxes and heavy parts with sharp edges.

101.5    State the general safety precautions associated with applying and removing external power.

1)  Circuit breakers and switches must be position as specified in the required MIMS. Failure to comply may cause aircraft systems to be energized to an in flight condition resulting in injury to personnel or damage to equipment. (Example; pitot tubes)

2)  To prevent shock and damage to aircraft inspect power cables and cable assembly plugs for pin  internal corrosion and damage or missing insulator washer or sleeves.

3)  Ensure power source is secured prior to application and removal.

4)  If using a mobile power unit ensure power unit is chocked and facing away from aircraft.

101.6    Identify the personnel danger areas during Auxiliary Power Unit (APU) operations.

1)  At the most center point of the APU exhaust it's exhaust velocity reaches 142 MPH from exhaust to the deck with a temperature of 328-350 Fahrenheit degrees.

2)  At 19-inch diameter the exhaust reaches a 24-MPH with a temperature range of 250-300 Fahrenheit. NOTE: This poses an extreme danger to anyone that might be working underneath the aft section of the aircraft. Or a fire hazard should a puddle of fuel or flammable solvent may be on the deck.

101.7    State the precautions/restrictions that apply to performing maintenance on ordnance loaded aircraft.

1)  Major maintenance on aircraft is prohibited.

2)  Minor maintenance and routine servicing necessary to ready the aircraft for the next launch may be conducted after all weapons have been safeties to the maximum degree as specified in loading check list.

101.8   Identify the precautions that must be observed when handling graphite or carbon/epoxy composite materials.

Wear respirators and goggles when exposed to these materials and in addition, wear close weave cotton gloves when handling these materials.

1)  Composite material normally does not present a hazard until the composite material is broken and fiber has been exposed raising health concerns.

2)  Fiber will embed into exposed skin and become difficult to remove

3)  The inhalation of graphite composite fibers resulting from aircraft fires and/or aircraft material damage may be harmful to personnel.
