Safety and tool safety Wear PPE (Personal protection equipment) Around all chemicals, liquids, fluids, flammables, Corrosives, Fuel. Keep flammables in explosion proof cabinet Keep kits and spill kits available and stocked. Spill kits help clean all messes and spills that need to be contained. Identify shop safety procedures Keep all PPEs available and good operating and clean hands stored well to prevent damage. Check all first aid kits and healing kits monthly to make sure they are up to date. Have well housekeeping with all personal belongings. Sweep after the work day to help keep the workplace clean. Keep tools clean Only keep needed equipment to reduce clutter. Keep as clean as you can in crammed up airplane working zone Protect hearing Must be in pilots field of vision as a flight technician Type of PPE in hangar Eye protection, sunglasses, safety glasses, goggles, face shield, welding goggles, welding helmet Hearing protection hearing protection should be used for anything over 85DB Ear plugs, Ear muffs Respiratory protection from welding, particles or dusts, metal fumes, sanding, grinding metals, grinding composites Skin protection from mist from painting, pressure cleaning, solvent gasses, all gasses Use barrier creams, gloves, long sleeves, long pants, bodysuits, aprons for skin protection Foot and head protection CSA shoes, helmet Radiation protection Lead lined clothing Fall protection Never work in hazardous location alone Wear high visibility clothing when working near or on flight line Identify what PPEs are used for different situations Removing PPE In order Remove gloves Remove gown Perform hand hygiene Remove eye protection Remove mask Perform hand hygiene ‘ FALL protection Guard rails Wear proper footwear Safety harness and lanyards Keep area clean and clear Maintain three points of contact when on ladder Do not carry items use rope instead Inspect safety harness and lanyard before use Inspect ladder before use Ensure platforms and lifts have secure railings Confined space Small workplaces can be very difficult to perform tasks. Poor air quality Chemical exposures Can have restricted entrance or exit Skin contact Inhalation Fire hazard Noise Structural hazards Entanglement Temperature visibility Use certain PPE to minimize risk in confined places Equipment used in confined space entry and rescues PPE Eye protection Hearing protection Respiratory protection Skin protection Foot and head protection Radiation protection Use temperature monitor in confined spaces Proper safety equipment contributes to physiological safety rubber gloves Safety glasses Rubber or grounded safety mats Electrical safety Factors that affect safety when dealing with electricity are Fear A certain amount of respect is healthy Overconfidence A certain level of confidence is healthy The two factors are major causes of accidents Lack of respect Types of electrical safety -Fire safety -Prevent fire accidents by keeping workplace clean -all power cords wires, and lines should be free of kinks and bends -Safety around compressed gasses Inspect air hoses for damage Unsafe hoses are to be replaced immediately Keep all connection in a “no leak condition” Never use compressed air to clean hands and clothing Air hoses should be straightened coiled and stored properly when not in use -Many compressed gasses accidents involve aircraft tire mounting To prevent use tire dollies and other appropriate lifting or mounting When inflating tire from initial build it has to be inclosed in some sort of cage Safety around machine tools FOD (Foreign Object Damaged) Fire safety Practices A use on Wood, paper, textiles and rubbish B use on flammable liquids C use on Electrical equipment What are the differences between fire classes and what are symbols for each Class A is ordinary combustible materials, such as wood, cloth, paper, upholstery materials, and so forth Class B is flammable petroleum products or other flammable or combustible liquids, greases, solvents, paints, and so forth Class C Is involving energized electrical wiring and equipment Class D Flammable metal (magnesium or sodium) Three things required for a fire Fuel, Heat, Oxygen Risks that can lead to class A fires. Poor shop housekeeping Improper lighting sources -incandescent bulbs -unprotected bulbs Careless welding or torch use Not disposing soiled rags (same for class B) Things that can lead to class C fire Poor shop housekeeping Improper lighting sources Incandescent bulbs Unprotected bulbs Overloading equipment Damaged equipment Not following manufacturer electrical recommendations Risks that can lead to Class D fires Poor shop housekeeping, careless welding or torch use Improper shop practices Cutting open open exhaust valves in recip engines Magnesium parts getting too hot when cutting, drilling, sanding, etc Dangers of fire in an aircraft maintenance environment Large amounts of fuel or vapor can be contained in the tanks of an aircraft The loss of life and equipment if there were to be an explosion or fire The smoke and fumes would be dangerous due to the many type of chemicals and materials used in an aircraft shop Entrapment in an aircraft is a possibility when performing maintenance Fire safety practices Hazardous situations that could lead to fire, explosions, and implosion Electrical tools that can create sparks, flammable explosive liquids, flammable explosive gasses, these situations result in high potential for fire. Identify appropriate fire extinguisher for different classes of fire Water extinguishers (used on class A fires) water deprives fire of oxygen, water cools the material of being burned, not recommended for class B fires, extreme caution must be used for class B fires, NEVER USE ON CLASS D FIRES, some are hand pumped, some ar pressurized, gas charge stored in the container with the water, the pressure of chemical gasses forces the water out. Carbon dioxide (CO2) extinguishers Are used for class A,B,C fires CO2 deprives fire of oxygen, Never use CO2 on class D Fires, the extinguisher can become extremely cold during and after the operation, extreme caution must be used when operating CO2 fire extinguishers in closed of confined areas to prevent suffocation, self expelling method of operation Dry powder extinguishers Effective on class B and C fires, best use on class D fires Gas cartridge stored pressure within the container Tossing the powder on the fire by hand, by scooping pails or buckets of the powder from large containers or barrels, dry powder is not the best on aircraft use expect for metal fires Halogenated hydrocarbon extinguishers First thing to do if fire occurs during engine start up Shut down the engine as soon as you are able to If fire occurs during the starting procedure, continue cranking to start the engine and blow out the fire. If the engine does not start and fire continues to burn, cancel the engine starting procedure. Safety around hazardous materials Blue diamond health hazard 0. Normal material 1. Slightly hazardous 2. Hazardous 3. Extreme danger 4. Deadly Red diamond fire hazard 0. Will not burn 1. Above 200F 2. Above 100F not exceeding 200F 3. Below 100F 4.
