(37 cards)
The SSRP manual covers what subjects
lethal warnings
safety precautions
servicing notes
replenishment procedures
Aircraft danger zones-fixed
NZAP reference for aircraft danger zones
wake- thrust produced by the propeller can have high wind speeds
windmilling- turbo-prop propellers are capable of rotating on their own if there is sufficient wind blowing
strobe/night effects- rotating props may appear stationary under certain lights
stationary blade danger- walking into a stationary prop may cause injury
blade markings-light ac:black and white
large ac- white/red/white painted prop tips
NZAP62XX.XXX-5-1.2: aircraft type, SS+RPs
major safety precaution associated with propeller driven aircraft
the major safety precaution associated with propeller driven aircraft is to never walk through the propeller arc, especially important whenever ground power is connected to the aircraft
aircraft danger zones-helicopter
NZAP reference for aircraft danger zones
main rotor
- as the speed of rotation diminishes, the blade can sag/sail to body height
- if the helicopter is on sloping ground the height above ground on the uphill side will be reduced
tail rotor
-can swing suddenly especially during take off
downwash
-creates a turbulent column of high velocity air
NZAP62XX.XXX-5-1.2: aircraft type, SS+RPs
safety precautions to be observed when working around helicopters with engines running
approach and leave the aircraft only with the prior permission of the person occupying the pilots seat
approach and leave the aircraft from the desired or acceptable zones as shown in the aircraft safety and servicing notes
never walk under the rotor disc on start up or shut down due to the possibility of blade sail
avoid the tail rotor and exhaust areas when aircraft running
beware of reduced rotor to ground clearances when operating on uneven surfaces
beware of the effects of downwash
what is a common danger area to all gas turbine engines and when is it most hazardous?
turbine disintegration area/turbine failure area
-exists perpendicular to the engine axis
propeller
-indicated along the fuselage
the most hazardous time is during startup. keep clear during startup
danger/s associated with the engine intake
may suck things in
- fod
- people
danger/s associated with the engine exhaust
high temperature
high velocity gas stream
at what level can personnel incur hearing damage if you are regularly exposed to?
what is the nzap reference
if you are regularly exposed to more than half an hour per day to a noise level that interferes with shouted conversation could incur hearing damage
NZAP6000-1 Chapter 10 section 1
high noise level can also damage what?
internal organs
when must the aircraft anti collision beacon be switched on as a warning device?
NZAP reference
Aircrew in control
-when aircraft if prepared for starting
ground running
-immediately before and during ground running of engines
ground pressurisation testing
-immediately before and during GPT
radiation hazard
-immediately before and during any period when a radiation hazard exists in the vicinity of AC
NZAP6000-1 chapter 10.12
what is the NZAP reference for HERO?
NZAP 6880.002-1, NZAP 6000-1 chapter 1
who needs to be aware of HERO
everyone
when a RF hazard is present or suspected, what needs to happen?
the NCO I/C armament is to halt work until
- the RF hazard has been removed
- the RF hazard has been suppressed by placing a one metre square HERO sign in a prominent position in front of AC
- enforce the following restrictions during the physical loading/unloading of EEDs:
1- no radio transmission from vehicles withing 10 metres of the aircraft
2- no aircraft radio transmissions within 20 metres of the aircraft
3- no transmissions from the susceptible aircraft
4-no transmissions from flightline radios within 5 metres of the aircraft
5-no transmissions from visiting/civilian aircraft. contact with the control tower may be necessary to ensure supression
6- no portable telephone transmissions within 5 metres of the aircraft
with regards to HERF, when cant aircraft transmitting equipment be used?
reference
AC transmitting equipment is not to be operated during fuelling and defuelling operations
NZAP 6004-001-1 leaftlet D7, NZAP 6005.053-1
what are the safety distances for the operations for transmitters
reference
fuelling and defuelling operations are to be carried out so that the fuelling zones are at least 10 metres from any operating VHF or UHF radio,
30 metres from any operating HF radio and
30m from any radiating RADAR
approved flightline management radios of less than 5 watt output may be used up to the fuel zone boundaries
NZAP 60005.053-1
with regards to HERP, what hazard/s exist because of the possibility of radio energy emission during ac radio transmitting equipment operation
reference
causing burns/ shock to personnel making contact with the aircraft aerial
charging metal items in close proximity to the aircraft aerials, or by sparking from one charged area to another causing ignition of volatile liquids, fire or explosion
NZAP 6004.001-1 leaflet D4, NZAP 6880.001-1 chapter 2
symptoms of HERP effects
pathological damage to certain organs
eyes
testes
herp effects can be reduced by
limiting the time spent in RF fields
limiting the intensity of the RF field where pers work
adhering to safety standards and safe work practices
RADHAZ safety precautions
anti-collision lights to be turned on to indicate the hazard
no replenishment during radio or RADAR transmission testing
suitable warning notices
safety person to keep pers away from radiating area
types of EOE
canopy jettison
ejectors racks
emergency exit
emergency exit slides
pyrotechnics
countermeasure
ordnance
explosive floats
winch/ cable cutters
automatics fire extinguishing system
safety devices for EOE
guarded arming switches
ground safety lockout pins
danger areas for EOE
reference
forward
aft
radial
NZAP 62XX.XXX-5-1.2: AC type
safety precautions for EOE
reference
only pers required for the task concerned are to be around the ac and the immediate vicinity
no replenishment during loading/unloading
suitable warning notices/signs
eoe to have safety pins fitted at all times and removed just prior to flight
