  • 2. 

    You can read smoke using only 1 of the attributes. 

    • True

    • False

    Correct Answer
    A. False
    Explanation
    This statement is false. Smoke cannot be accurately read using only one attribute. Smoke can be analyzed using multiple attributes such as color, density, smell, and composition to determine its source, intensity, and potential hazards. Therefore, it is incorrect to say that smoke can be read using only one attribute.

    Rate this question:

  • 3. 

    An essential concept of reading smoke is?

    • Smoke is fuel

    • Fuels have changed

    • Smoke will ignite with proper temperature and air mixture

    • All of the above

    Correct Answer
    A. All of the above
    Explanation
    The correct answer is "All of the above." This means that all three statements mentioned in the options are essential concepts of reading smoke. The first statement, "Smoke is fuel," highlights the fact that smoke is a product of incomplete combustion and contains unburned fuel particles. The second statement, "Fuels have changed," suggests that different types of fuels produce different types of smoke, which can vary in color, density, and composition. The third statement, "Smoke will ignite with proper temperature and air mixture," emphasizes that smoke can be flammable and can ignite under specific conditions. Therefore, understanding these concepts is crucial for reading smoke accurately.

    Rate this question:

  • 4. 

    Reading smoke is an absolute science.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    The statement suggests that reading smoke is an absolute science, but the correct answer is false. This means that reading smoke is not an absolute science. It implies that there may be some subjectivity or uncertainty involved in interpreting smoke signals or indicators.

    Rate this question:

  • 5. 

    The darker the smoke, the _____ the smoke.

    • Colder

    • Hottter

    • Thicker

    • Cleaner

    Correct Answer
    A. Hottter
    Explanation
    The correct answer is "Hottter" because when smoke is darker, it indicates that it is hotter. Darker smoke is usually a result of incomplete combustion, which means that the fuel is not burning efficiently and producing more soot and particles. This typically happens at higher temperatures, making the smoke darker. Therefore, the darker the smoke, the hotter it is.

    Rate this question:

  • 6. 

    The transition from a contents fire to a structure fire is best noticed by observing ______ smoke.

    • White

    • Grey

    • Brown

    • Black

    Correct Answer
    A. Brown
    Explanation
    The transition from a contents fire to a structure fire is best noticed by observing brown smoke. This is because brown smoke indicates that the fire has spread beyond the initial contents and is now affecting the structure itself. The brown color is typically caused by the burning of building materials such as wood, which release darker and thicker smoke compared to the lighter smoke produced by burning contents. Therefore, the presence of brown smoke is a clear indication of a more serious fire situation.

    Rate this question:

  • 7. 

    Reading smoke is best performed _______.

    • Outside

    • Inside

    • Both inside and outside

    Correct Answer
    A. Outside
    Explanation
    Reading smoke is best performed outside because being outdoors provides better visibility and a clearer view of the smoke. Inside a building, smoke can get trapped, leading to poor visibility and difficulty in accurately interpreting the characteristics of the smoke. However, outside, there is better air circulation, allowing the smoke to disperse more easily and providing a more accurate reading of its color, density, and movement. Additionally, being outside reduces the risk of inhaling harmful smoke particles, ensuring safety while analyzing the smoke.

    Rate this question:

  • 8. 

    The number 1 warning sign of flashover is ______ smoke.

    Correct Answer
    Turbulent
    Explanation
    Flashover is a phenomenon that occurs in a fire when all combustible materials in a room reach their ignition temperature simultaneously, resulting in a sudden and intense fire. Turbulent smoke refers to smoke that is agitated and moving rapidly, indicating high heat and potential for flashover. This turbulent smoke is a clear indicator that the fire is reaching a critical point and flashover is imminent. Therefore, turbulent smoke is considered the number 1 warning sign of flashover.

    Rate this question:

  • 9. 

    You can also read smoke by observing the flames.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    Observing flames alone is not sufficient to determine the presence of smoke. Smoke is the result of incomplete combustion and may not always produce visible flames. Therefore, it is not accurate to say that one can determine the presence of smoke solely by observing flames.

    Rate this question:

  • 10. 

    Forms of fuel in smoke are (check all that apply)

    • Particulates

    • Liquids

    • Aerosols

    • Gases

    Correct Answer(s)
    A. Particulates
    A. Aerosols
    A. Gases
    Explanation
    Smoke is a complex mixture of different substances released during combustion. Particulates refer to solid particles suspended in the air, such as soot and ash, which are commonly found in smoke. Aerosols are tiny liquid or solid particles dispersed in a gas, which can also be present in smoke. Gases, on the other hand, consist of vaporized substances released during combustion, such as carbon monoxide and carbon dioxide. Therefore, all three options - particulates, aerosols, and gases - are forms of fuel that can be found in smoke.

    Rate this question:

  • 11. 

    Which attribute best helps us locate the seat of the fire?

    • Density

    • Color

    • Velocity

    • Volume

    Correct Answer
    A. Velocity
    Explanation
    Velocity is the best attribute for locating the seat of the fire because it refers to the speed at which the fire is spreading. By determining the velocity of the fire, we can identify the direction and intensity of its movement, which can help us pinpoint the origin or seat of the fire. This information is crucial for effective firefighting and containment strategies. Density, color, and volume may provide some information about the fire, but they are not as directly related to its location as velocity.

    Rate this question:

  • 12. 

    Volume, velocity, density, and color best describe the  __________.

    Correct Answer
    The four attributes of smoke
    4 attributes of smoke
    four attributes of smoke
    attributes of smoke
    smoke attributes
    four smoke attributes
    4 smoke attributes
    Explanation
    The given answer options all describe the attributes of smoke. Smoke can be described in terms of its volume, velocity, density, and color. These attributes help to characterize and differentiate different types of smoke.

    Rate this question:

  • 13. 

    Quality of burning, severity of event, and continuity of fuels can all be determined by the smokes _______.

    • Volume

    • Density

    • Velocity

    • Color

    Correct Answer
    A. Density
    Explanation
    Density can be used to determine the quality of burning, severity of event, and continuity of fuels. A higher density of smoke indicates a higher concentration of particles, which suggests a more intense burning or a larger amount of fuel being consumed. On the other hand, a lower density of smoke suggests a less severe event or a lower amount of fuel being burned. Therefore, density is a useful measure in assessing the characteristics of smoke and the associated fire.

    Rate this question:

  • 14. 

    Smoke color is indicative of the type of fuel burning.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    The color of smoke is not indicative of the type of fuel burning. The color of smoke is determined by the presence of certain chemicals and particles in the smoke, such as carbon, soot, and ash. The color can vary depending on the composition of the fuel and the conditions of combustion. For example, smoke from burning wood may appear white or gray, while smoke from burning oil can be black. Therefore, it is not accurate to say that the color of smoke directly indicates the type of fuel burning.
