SAFETY PRECAUTIONS – AIRCRAFT AND WORKSHOP Flashcards
The external protection is
earmuff/headphone type
OXYGEN SAFETY CONSIDERATIONS
Before any work is attempted, an
adequate fire extinguisher should be on hand. Cordon off the area and post “NO SMOKING”
placards.
Ensure that all tools and servicing equipment are clean and avoid power on checks and use of
the aircraft electrical system
SAFETY AROUND COMPRESSED GASES
The system should have _________ installed and should be drained at regular intervals.
water sumps
Air used for paint spraying should be
filtered to remove oil and water

FIRE PROTECTION
something that will, in the presence of heat, combine with oxygen, thereby releasing more heat and as a result reduces itself to other chemical compounds;
Fuel
FIRE PROTECTION
accelerates the combining of oxygen with fuel, in turn releasing more heat
Heat
FIRE PROTECTION
the element which combines chemically with another substance through the process of oxidation. Rapid oxidation, accompanied by a noticeable release of heat and light, is called combustion or burning
Oxygen
occur in ordinary combustible materials, such as wood, cloth, paper, upholstery materials, and so forth
-Class A fires
occur in flammable petroleum products of other flammable or combustible liquids, greases, solvents, paints, and so forth
Class B fires
involve energized electrical wiring and equipment
Class C fires
defined as fire in flammable metal
Class D fire
involve magnesium in the shop or in aircraft wheels and brakes, or are the result of improper or poorly conducted welding operations
Class D fires
best type to use on Class A fires
Water extinguishers
Never use water-type fire extinguishers on
Class D fires
are used for Class A, B, and C fires, extinguishing the fire by depriving it of oxygen
Carbon dioxide (C02) extinguishers
Never use C02 on
Class D fires
The pressurized types of extinguishers may have a gas charge stored in the container with
the water, or it may contain a “soda-acid” container
are most effective on Class B and C fires
Halogenated hydrocarbon extinguishers
(commonly called Freon™ by the industry), are numbered according to chemical formulas with Halón™ numbers
Halogenated hydrocarbon
chemical formula CCI4, has an Underwriters Laboratory (UL) toxicity rating of 3. As such, it is extremely toxic
Carbon tetrachloride (Halón 104),
is not recommended for aircraft use
Halón 1001
chemical formula CH3Br, is a liquefied gas with a UL toxicity rating of 2. This chemical is very toxic, it is corrosive to aluminum alloys, magnesium, and zinc.
Methyl bromide (Halón 1001),
chemical formula CBrCIF2, is a liquefied gas with a UL toxicity rating of 5.
Bromochlorodifluoromethane (Halón 1211),
chemical formula CF3Br, is also a liquefied gas with a UL toxicity rating of 6. It has all the characteristics of Halón 1211
Bromotrif luoromethane (Halón 1301),
