(003) What characteristic refers to how easy a liquid changes into a vapor state?
- A.
Volatility.
- B.
Viscosity.
- C.
Boiling point.
- D.
Vapor pressure.
Correct Answer
A. Volatility.Explanation
Volatility refers to the characteristic of how easily a liquid changes into a vapor state. It is a measure of the tendency of a substance to vaporize. Substances with high volatility evaporate quickly and easily, while substances with low volatility evaporate slowly. Volatility is influenced by factors such as temperature, pressure, and intermolecular forces.Rate this question:

(003) This term is used to describe the temperature at which a liquid actively starts to vaporize.
- A.
Volatility.
- B.
Fire point.
- C.
Flash point.
- D.
Boiling point.
Correct Answer
D. Boiling point.Explanation
The term "boiling point" refers to the temperature at which a liquid begins to vaporize actively. It is the point where the vapor pressure of the liquid equals the atmospheric pressure, causing the liquid to rapidly convert into a gas. The other options, volatility, fire point, and flash point, are not directly related to the temperature at which a liquid starts to vaporize. Volatility refers to how easily a substance evaporates, while fire point and flash point are temperatures at which a liquid gives off enough vapor to ignite or produce a flash, respectively.Rate this question:

(003) Combustible liquids have a flash point higher than
- A.
100 degrees (°) Fahrenheit (F).
- B.
120° F.
- C.
140° F.
- D.
150° F.
Correct Answer
A. 100 degrees (°) Fahrenheit (F).Explanation
Combustible liquids have a flash point higher than 100 degrees Fahrenheit (F). Flash point refers to the lowest temperature at which a substance can vaporize and ignite when exposed to an open flame or heat source. Therefore, if a liquid has a flash point higher than 100 degrees Fahrenheit, it means that it requires a higher temperature to ignite, making it less prone to catching fire easily compared to liquids with lower flash points.Rate this question:

(003) What is the minimum flash point of JP–5 jet fuel?
- A.
–20 degrees () Fahrenheit (F).
- B.
–40° F.
- C.
100° F.
- D.
140° F.
Correct Answer
D. 140° F.Explanation
JP-5 jet fuel is a type of aviation fuel used by the military. The flash point of a fuel is the lowest temperature at which it can vaporize to form an ignitable mixture in air. In the case of JP-5 jet fuel, the minimum flash point is 140°F. This means that the fuel will not ignite unless the temperature reaches or exceeds 140°F. It is important to know the flash point of a fuel as it helps determine its safety during storage, handling, and transportation.Rate this question:

(004) Which is not a hazard of liquid nitrogen?
- A.
Reduces the concentration of oxygen.
- B.
Freezes or badly damages human tissue upon contact.
- C.
Burns or explodes upon contact with oil, grease, and jet fuel.
- D.
Builds up to tremendous pressure if it evaporates in a confined area.
Correct Answer
C. Burns or explodes upon contact with oil, grease, and jet fuel.Explanation
Liquid nitrogen does not burn or explode upon contact with oil, grease, and jet fuel. It is a cryogenic liquid that can cause severe frostbite or tissue damage upon contact due to its extremely low temperature. It can also displace oxygen in a confined space, leading to a reduced concentration of oxygen. Additionally, if liquid nitrogen evaporates in a confined area, it can build up tremendous pressure, posing a hazard. However, it does not have a reaction with oil, grease, and jet fuel that would cause it to burn or explode.Rate this question:

- A.
Daily.
- B.
Weekly.
- C.
Monthly.
- D.
Semiannually.
Correct Answer
D. Semiannually.Explanation
Under the Air Force Occupational Safety and Health (AFOSH) program, the fuels safety monitor is required to brief all personnel on safety matters twice a year, or semiannually. This ensures that personnel are regularly updated and informed about safety protocols and procedures in relation to fuel safety. Regular briefings help to minimize the risk of accidents and promote a safe working environment for all personnel involved in fuel-related operations.Rate this question:

(005) Which source of accidents is the principle cause of disabling injuries to office workers?
- A.
Falling.
- B.
Using hand tools.
- C.
Handling heavy equipment.
- D.
Striking against material or equipment.
Correct Answer
A. Falling.Explanation
Falling is the main source of accidents that cause disabling injuries to office workers. This can include slips, trips, or falls from elevated surfaces such as stairs, ladders, or slippery floors. Falling accidents can result in serious injuries such as broken bones, sprains, or head injuries. It is important for office workers to be aware of their surroundings, use proper safety measures, and report any potential hazards to prevent these accidents from occurring.Rate this question:

(005) For safety measures, all Air Force electrical equipment must have
- A.
Grounded plugs.
- B.
Single insulation.
- C.
Double insulation.
- D.
Explosion-proof plugs.
Correct Answer
A. Grounded plugs.Explanation
For safety reasons, all Air Force electrical equipment must have grounded plugs. This is because grounding helps to prevent electrical shock and reduces the risk of electrical fires. Grounded plugs have a third prong that connects to the ground wire in the electrical system, providing a safe path for any excess electrical current to flow into the ground. This helps to protect both the equipment and the individuals using it from potential harm. Single insulation, double insulation, and explosion-proof plugs do not provide the same level of safety as grounded plugs.Rate this question:

- A.
"Follow Me"‖ trucks.
- B.
Refueling units.
- C.
Fire trucks.
- D.
Tugs.
Correct Answer
A. "Follow Me"‖ trucks.Explanation
"Follow Me" trucks do not have to yield the right of way to moving aircraft because their primary function is to guide and direct aircraft on the ground. They are responsible for leading aircraft to and from parking areas, taxiways, and runways. Their role is crucial in ensuring the safe movement of aircraft on the ground, and therefore, other vehicles, such as refueling units, fire trucks, and tugs, must yield to them.Rate this question:

(005) How often should fill stand emergency shutdown switches be tested for proper operation while the system is operating?
- A.
Daily.
- B.
Weekly.
- C.
Monthly.
- D.
Semiannually.
Correct Answer
C. Monthly.Explanation
Emergency shutdown switches should be tested for proper operation while the system is operating on a monthly basis. This regular testing ensures that the switches are functioning correctly and can effectively shut down the system in case of an emergency. Testing them more frequently, such as daily or weekly, may not be necessary and could disrupt the system's normal operation. However, testing them less frequently, such as semiannually, may increase the risk of a malfunction going unnoticed for an extended period of time.Rate this question:
