Define the term pyrotechnics
|
- Items that produce their effect by burning, and are consumed in the process. Items that produce a bright light for illumination or colored lights or smoke for signaling
|
|
|
.2 State the purpose and burn time of the following pyrotechnics:
MK 80 MOD 0 signal[ MK 124 MOD 0 signal MK 25 MOD 4 (marine location marker) MK 58 MOD 0 (marine location marker) |
MK 80 MOD 0 signal[ref. a, p. 4-3] - Used by downed aircrew personnel as a distress-signaling device. Burn time is a minimum of 4 seconds.
MK 124 MOD 0 signal[ref. d, p. 9-37] - Used by downed aircrew personnel as a signaling device by using either smoke or flare. Approximately 5 inches in length by 1.5 inches in diameter. Aluminum case with protective caps on both ends. The flare end has two raised beads on the protective cap to facilitate use at night. Produces red flare for night use and orange smoke for day use. Burn time: 20 seconds. MK 25 MOD 4 (marine location marker) [ref. a, p. 4-10] - Provides day or night reference points for marking the course of enemy submarines in antisubmarine warfare operations. They are suitable for any type of sea-surface reference-point marking that calls for both smoke and flame for a period of 10 to 20 minutes. MK 58 MOD 0 (marine location marker) [ref. a, p. 4-12] - Used during day or night in any condition that calls for long-burning, smoke and flame reference-point marking on the ocean's surface. Used for ASW, SAR, man-overboard markings, and as a target for practice bombing at sea. Produces a yellow flame and white smoke for a minimum of 40 minutes and a maximum of 60 minutes. It is visible for at least 3 miles under normal operating conditions. |

|
.3 State the purpose of the Explosives Handling Personnel Qualification and Certification Program
|
Sets guidelines for weapons certification. Is applicable to all personnel in the Naval Establishment whose duties require evolutions or tasks involving explosive devices.
|
|
|
.4 Explain the purpose of the Explosive Mishap Report (EMR).
|
EMR applies to explosive incidents involving-- conventional ordnance ammunition and explosive systems and devices (including cartridge actuated devices, aircrew escape
propulsion systems, and devices used to launch or fire explosive systems) resulting in an actual unintentional detonation, firing, deflagration, burning, launching of ordnance material (including all ordnance impacting off range), leaking or spilled propellant fuels and oxidizers (less Otto Fuel), or chemical agent release. Even if a system works as advertised, if human error contributed to an incident or injury, report the event as an explosive mishap |
|
|
State the purpose of the Naval Ordnance Maintenance Management Program (NOMMP).
|
To issue maintenance policies, procedures, & responsibilities for the conduct of the NOMMP at all levels of airborne weapons maintenance.
|
|
|
Explain the conditions for aircraft grounding
|
(during weapons/ordnance load/unload).
Resistance between the aircraft structure and ground is 10,000 ohms or less. The ground systems shall be visually checked frequently and at least semiannually to ensure that the connections are secure and free from paint, corrosion, or foreign materials, which might impair the efficiency of the system. Aircraft grounding systems shall be tested for electrical resistance and continuity in accordance with NAVSEA OP-5 Vol. I and MIL-HDBK-274(AS). |
|
|
State the purpose of a stray voltage check
|
To ensure the correct firing voltage is available at the appropriate station when the cockpit switches are properly set, and to ensure that voltage or stray voltage is not present before electrical connection of certain launchers, such as rocket launchers, is made
|
|
|
State the purpose of the Explosive Ordnance Disposal (EOD) unit
|
Personnel with special training and equipment who render explosive ordnance safe, make intelligence reports, and supervise the safe removal of ordnance.
|
|
|
State the purpose of the Hazards of Electromagnetic Radiation to Ordnance (HERO).
|
Radio frequency (RF) radiation can and may trigger a detonation in certain types of ordnance munitions. Hazards of Electromagnetic Radiation to Ordnance was designed as a safeguard to prevent mobile RF emitting devices (such as VHF and HF radios) from entering into an area which ordnance may be present, or from placing ordnance in an area where a fixed (permanent) RF transmitter is located.
|
|
|
State the three categories of HERO susceptibility
|
HERO Safe Ordnance
HERO Susceptible Ordnance HERO Unsafe Ordnance |
