18
Q

What are some uses for potassium hydroxide and sodium hydroxide commonly found on AF bases?

A

Potassium hydroxide is an alkali-electrolyte for nickel cadmium batteries; sodium hydroxide is an alkali used in paint strippers and aircraft-cleaning compounds

19

A

Welding

20
Q

What are the two basic types of batteries used in AF workplaces?

A

Acid and caustic

21
Q

What is the primary hazard during electroplating operations?

A

inhalation of metal fumes

22
Q

What are the primary hazards associated with AGE?

A

Noise, exhaust emissions, production of carbons, and use of solvents that may cause dermatitis

23
Q

Degreasing solvents, mercury, acids, ionizing radiation, epoxy and resins, noise, and soldering hazards

A

exposure hazards of a medical maintenance worker

24
Q

Which control method is using citrus cleaners instead of trichlorethylene an example of?

A

Substitution

25
Q

Rotating workers through a hazardous environment regulates hazardous exposures through which control method?

A

Administrative

26
Q

What should be done to PPE to ensure protection for the worker?

A

Check to ensure it protects the worker against the specific hazard in the workplace

27
Q

What are the types of respirators used to protect workers from gas, vapor, and particulate hazards?

A medical service program that ensures that all bases are striving to make working conditions safe and healthy for all employees

A

Air Force Occupational & Environmental Health Program

29
Q

What is the chief goal of industrial hygiene surveillance?

A

The preservation and the improvement of the health of the work force

30
Q

A detailed assessment of the operations performed, specific risks, available control measures, an evaluation of the effectiveness of those control measures. Consideration is also given at that time to the interrelationships of chemical, physical, biological, and biomechanical stresses that may exist in the industrial environment

A

comprehensive baseline study

31
Q

Who may request a special survey from the BE section?

A

A health care practitioner, a supervisor, an employee, employee representative, or PH

32
Q

What are the three phases of the general survey process followed for chemical agent exposure surveillance?

A

Recognition, evaluation, and control

33
Q

What are the two types of evaluations used for physical agent exposure?

A

Mathematical predictions and actual measurements

34
Q

A level of measurement which is half the OEEL established for each hazard

A

AL (action level)
