Safety while working on Aircraft
Aircraft maintenance work includes inspection and repair of aircraft and its components. Good work practices ensure aircraft and worker safety. Safety is everyone’s business. However, maintenance personnel must watch for their own safety and for the safety of other colleagues working around them.
Keeping the cleanliness of shop, hangar and ramp is essential and first step to ensure safety and efficient maintenance.
Communication is key to ensuring everyone’s safety. If anyone are conducting their actions in an unsafe manner, communicate with them, reminding them of their safety.
Working with electrical equipment – Electrical Safety
When dealing with electricity, two factors that affect safety are fear and overconfidence. To safely deal with electrical equipment, avionics technician must have working knowledge of the principles of electricity and healthy respect for its capability to do both work and damage, because small mistakes or negligence can cause serious injury. Use of proper safety equipment can provide a psychological assurance of workers. The use of rubber gloves, safety glasses, rubber or grounded safety mats, and other safety equipment contributes to the overall safety of the technician working on or with electrical equipment.
Electricity can be a cause of fire, an important factor in preventing electrical fires is to keep the area around electrical work or electrical equipment clean, uncluttered, and free of all unnecessary flammable substances.
Ensure Safety Around Compressed Gases. Always follow instructions while working with compressed air or nitrogen bottle.
Ensure Safety Around Machine Tools. Each machine has its own set of safety instructions and practices. Follow proper safety guide.
Safety Around Hazardous Materials
Material safety are most important regard to shop safety. If you are working in shop, ensure about the hazard marking label on hazardous material. Diamond-shaped labels (risk diamond) are a simple and quick way to determine the risk of hazardous material within the associated container. To ensure proper personnel safety you should always follow Material Safety Data Sheet (MSDS).
Ramp is a place of dangerous activity. Technicians who perform maintenance in line on the ramp must constantly be aware of what is going on around them. The noise on ramp comes from various sources. Some of these sources of noise are other aircraft operation at airport, APU running, and ground handling equipments. Combined all sources together, the noise on the ramp can cause hearing loss. Hearing protection is also essential when working with pneumatic drills, rivet guns, or other loud tools. There are many types of hearing protection available, Earmuffs is one of those. Always use earmuff according to noise label. Noise label is universally measured in db (decibel). The decibel (db) is a unit used to measure the intensity of a sound.
Foreign Object Damage (FOD)
Foreign object damage (FOD) is any damage to aircraft, personnel, or equipment due to any loose objects. The best way to control FOD, keep ramp and operation areas clean. Tools control program helps to prevent FOD. Never leave tools or other items around the intake of a turbine engine. Modern gas turbine engine creates a low-pressure area in front of the engine that causes any loose object to be drawn into the engine. The exhaust of these engines can propel loose objects at great distance with enough force to damage anything that is hit. The importance of a FOD control program should not be ignored when a technician considers the cost of engines, components, or a human life.
Safety Around Airplanes
Turbine engine intakes and exhaust can also be very hazardous areas, propeller too in case of turboprop engine. No can assume that pilot mind and activities during taxiing of aircraft. Always stay away in view of pilot. Be aware of aircraft fluids like ATF (Air Turbine Fuel), Engine oil, and hydraulic oil, that can be detrimental to skin. When operating ground support equipment around the aircraft, ensure that there is sufficient space or clearance between GSE and aircraft, and secure it, so that it can’t roll into the aircraft.
