1-1 AMG045 The Material Safety Risk Diamond illustrated in Figure 1-1 below indicates the A. material is mildly radioactive. B. material flammability risk is high; and reactivity to water is high. C. material is biologically hazardous, but not flammable. - ANS Answer B. The risk diamond on the Safety Data Sheet (SDS) label provides a quick reference to the risks associated with the product. Its four color segments represent Flammability (Red), Reactivity (Yellow), Health (Blue), and Special Hazards (White). The numbers (0-4) in the blocks represent the various levels for each hazard; the higher the number the higher the risk. There are only two approved symbols for Special Hazards: letter W with a line through it meaning that the material has a high reactivity to water and OX meaning that the material is a strong oxidizer. [Ref: General Handbook H-8083-30A-ATB, Chapter 01 Page 3 Which government agency regulates policy regarding workplace safety in aviation facilities? A. FAA B. EPA C. OSHA - ANS 1-2 Answer C. The U.S. Department of Labor's Occupational Safety and Health Administration (OSHA) regulates policy regarding workplace safety. The Federal Aviation Administration deals with aviation safety, among other policies, and the Environmental Protection Agency regulates policy regarding the environment. [Ref: General Handbook H-8083-30A-ATB, Chapter 01 Page 3] 1-3 AMG045 What sound level becomes dangerous and requires the use of hearing protection? A. 100 db B. Varies depending on frequency C. Varies depending on duration - ANS 1-3 Answer C. Hearing protection is extremely important. Such machines as chainsaws, pneumatic drills, and snowmobiles produce a noise level of 100dB can cause hearing loss. Frequency (vibrations per second) particularly in the high range, such as in musical instruments, can also cause hearing loss. Duration of exposure is extremely critical in determining hearing loss, the longer the duration the greater the potential for loss. In each of the situations, you should wear hearing protection. However, duration plays a significant role when OSHA determines the requirements for mandatory hearing protection, which is what this question implies with the use of the word "requires". The bottom line here is PROTECT your hearing. Always wear hearing protection working with pneumatic drills, rivet guns, or other loud or noisy tools or machinery all producing high dB ranges and high frequency ranges, and even short duration exposure to these sounds can cause a hearing loss. Continued exposure will cause hearing loss. Don't forget to protect your hearing at home and during recreational activities as well. Duration, or how long you are exposed to a noise level, does not stop accumulating when you leave the job site. Listening to loud music on the way home adds to the total duration. [Ref: General Handbook H-8083-30A-ATB, Chapter 01 Page 4] 1-4 AMG045 A person should approach or leave a helicopter in the pilot's field of vision whenever the engine is running in order to avoid A. the tail rotor. B. the main rotor. C. blowing dust or debris caused by rotor downwash. - ANS 1-4 Answer A. Always approach the helicopter in view of the pilot. Approaching for any other direction is dangerous; the tail rotor is invisible when operating and the pilot will not see you. Additional safety precautions is not to approach the helicopter if the main rotor is turning, unless approved to do so and in the pilot's field of vision. If you should get dust or debris in your eyes while approaching or leaving a helicopter, immediately sit down to avoid further possible injury. [Ref: General Handbook H-8083-30A-ATB, Chapter 01 Page 5] 1-5 AMG045 Which of the following conditions are required for fire? A. Heat, oxygen, fuel B. Heat, friction, carbon dioxide C. Fuel, combustion, heat - ANS 1-5 Answer A. Three things are required for a fire: 1. Fuel or a combustible material, 2. Heat to raise the material to its ignition temperature, 3. Oxygen to sustain the combustion. The chemical reaction caused by the interaction of these three ingredients creates fire. By eliminating even one, a fire cannot occur. [Ref: General Handbook H-8083-30A-ATB, Chapter 01 Page 5] 1-6 AMG045 A Class B fire involves A. petroleum products or combustible liquids. B. energized electrical wiring. C. material such as wood, paper, upholstery, etc. - ANS 1-6 Answer A. Class B fires are caused by flammable petroleum products of other flammable or combustible liquids, greases, solvents, paints, and so forth. [Ref: General Handbook H-8083-30A-ATB, Chapter 01 Page 5] 1-7 AMG045 Which of the following is the most satisfactory extinguishing agent for use on a carburetor or intake fire? A. Dry chemical B. A fine water mist C. Carbon dioxide - ANS 1-7 Answer C. Because carburetors and intake fires will have grease and fuel associated with them, you can eliminate "a fine water mist" as an answer. Although both dry chemical and carbon dioxide extinguishers can be used on Class B fires, the best answer is carbon dioxide (CO2), because dry chemical agents can leave chemical residues and dust making cleanup difficult and cause additional damage. [Ref: General Handbook H-8083-30A-ATB, Chapter 01 Page 6-8] 1-8 AMG045 Never use CO2 type fire extinguishers on burning metal because it A. can release toxic fumes. B. can cause explosive conditions on the metal. C. is generally ineffective. - ANS 1-8 Answer B. Never use CO2 on Class D fires. As with water extinguishers, the cooling effect of CO2 on the hot metal can cause explosive expansion of the metal. [Ref: General Handbook H-8083-30A-ATB, Chapter 01 Page 6] 1-9 AMG045 The principle drawback of Halon 104, 1001, and 1202 type fire extinguishers is that they: A. Must be stored in high pressure cylinders. B. Are extremely toxic. C. Are ineffective against electrical fires. - ANS 1-9 Answer B. Halon 104, 1001, and 1202 all have high Underwriters Laboratory (UL) toxicity ratings and are not recommended for aircraft use. [Ref: General Handbook H-8083-30A-ATB, Chapter 01 Page 6
