Previously I did cover the shop (hangar) safety and while working with different tools. Today, I will try and go go through some of the flight safety one needs to observe to keep both the aircraft and the personnel from potential harm.
Most blades have high-visibility markings, to ensure that they can be seen when they are turning. These markings vary from a yellow blade tip marking, to black and white alternate stripes along the full blade length.
To reduce the risk of propeller and rotor blade strikes, it is best to follow the laid out procedures approaching and leaving aircraft vicinity when operational.
When dealing with jet engines, the dangers involved include noise which if exposed to for a long duration may cause deafness, risk of intake suction and the risk of jet blasts.
To protect the ear against excessive noise exposure, you can use the earmuff or head phonesHearing Protection. Hearing protection is essential when working with pneumatic drills, rivet guns, or other loud tools.
When the engine is running, there are minimum recommended distances to keep both behind and in front of the engine to avoid harm due to jet blasts and suction effect of the engine.
When the engine is running, there are dangers of foreign object damage (FOD) due to the loose concrete particles being sucked into the engine. Therefore, to avoid this, keep the ramp and the operation areas clean, have a good tool control program, never leave tools or an other items infront of the jet engines.
Some of the precautions to take when around aircrats are:
Stay within the pilot's view of a taxiing aircraft.
Smoking or open flames are near an aircraft in operation.
Be aware of aircraft fluids that can corrode the skin.
When operating support equipment around aircraft, be sure to allow space between it and the aircraft and secure it so it cannot roll into the aircraft.
All items in the area of operating aircraft must be stowed properly.
Safety Around Helicopters
Helicopters have different features. These differences must be learned to avoid damaging the helicopter or cause injury to the technician.
When approaching a helicopter while the blades are turning, adhere to the following guidelines to ensure safety of both you and the helicopter.
Observe the rotor head and blades to see if they are level. This allows maximum clearance when approaching the helicopter.
Approach the helicopter in view of the pilot.
Never approach a helicopter carrying anything with a vertical height that the blades could hit. This could cause blade damage and injury to the individual.
Never approach a single-rotor helicopter from the rear. The tail rotor is invisible when operating.
Never go from one side of the helicopter to the other by going around the tail. Always go around the nose of the helicopter.
When securing the rotor on helicopters, check the maintenance manual for the proper method. Using the wrong method could damage the bearing.
NB:
The flight line incidences can be avoided or minimized if all adhere to the rules and take necessary precaution while working as some flight line accidents especially those involving the rotors and propellers in operation are almost always fatal.
