  • 2. 

    Initial lighting of the acetylene produces large amounts of soot.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    The initial lighting of acetylene produces large amounts of soot because acetylene is a hydrocarbon compound that undergoes incomplete combustion when ignited. Incomplete combustion occurs when there is insufficient oxygen present, leading to the production of carbon particles or soot. Therefore, it is true that the initial lighting of acetylene produces large amounts of soot.

    Rate this question:

  • 3. 

    Open the acetylene cylinder valve not more than one turn.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    The statement is advising to open the acetylene cylinder valve not more than one turn. This is a safety precaution because opening the valve too much can cause a sudden release of acetylene, which is a highly flammable gas. By only opening the valve one turn, it allows for a controlled flow of gas and reduces the risk of accidents or explosions. Therefore, the statement is true.

    Rate this question:

  • 4. 

    When lighting the acetylene gas the oxygen should be turned off on the torch tip.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    When lighting the acetylene gas, it is important to turn off the oxygen on the torch tip. This is because acetylene gas is highly flammable and can create a dangerous situation if it comes into contact with oxygen. By turning off the oxygen, the risk of an explosion or fire is minimized. Therefore, the statement "When lighting the acetylene gas the oxygen should be turned off on the torch tip" is true.

    Rate this question:

  • 5. 

    The Acetylene Tank is green.

    • True

    • False

    Correct Answer
    A. False
  • 6. 

    ALWAYS turn the oxygen cylinder valve all the way open

    • True

    • False

    Correct Answer
    A. True
    Explanation
    It is important to always turn the oxygen cylinder valve all the way open because this ensures a continuous flow of oxygen. Partially opening the valve may result in a reduced flow or interruption of oxygen supply, which can be dangerous for individuals who rely on oxygen therapy. Therefore, it is necessary to fully open the valve to ensure a consistent and adequate supply of oxygen.

  • 7. 

    The vent should be turned off when using the oxyacetylene torch.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    The vent should not be turned off when using the oxyacetylene torch because this torch produces a flame that can release harmful gases and fumes, such as carbon monoxide. Keeping the vent open allows for proper ventilation and helps to remove these dangerous gases from the work area, ensuring the safety of the user.

    Rate this question:

  • 8. 

    The oxygen is turned off first after you are done with the torch.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    It is important to turn off the oxygen first after using a torch because oxygen supports combustion and can cause a fire or explosion if left on. By turning off the oxygen first, the risk of any accidental ignition is minimized.

    BEWARE OF HIGH ACETYLENE PRESSURE. NEVER USE ACETYLENE GAS WHEN THE PRESSURE IS GREATER THAN ___________ POUNDS PER SQ. IN. (acetylene gas when compressed to more than _______________ pounds per sq. in. becomes a very high explosive.)

    • 5

    • 10

    • 15

    Correct Answer
    A. 15
    Explanation
    Acetylene gas becomes highly explosive when compressed to more than 15 pounds per square inch. This is why it is important to beware of high acetylene pressure and never use acetylene gas when the pressure exceeds this limit.

    Rate this question:

  • 10. 

    Acetylene line pressure should be what psi?

    • 5

    • 10

    • 15

    Correct Answer
    A. 5
    Explanation
    The correct answer is 5 because acetylene line pressure should typically be set at a maximum of 5 psi to prevent the risk of explosion. Higher pressures can cause the acetylene gas to become unstable and highly reactive, increasing the likelihood of a dangerous incident. Therefore, it is important to ensure that the acetylene line pressure is kept at a safe level of 5 psi or below.

    Rate this question:

  • 11. 

    After using the Oxyacetylene torch you should turn off the acetylene first and then the oxygen.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    The correct order for turning off the Oxyacetylene torch is to first turn off the oxygen and then the acetylene. This is because if the acetylene is turned off first, the excess oxygen can continue to flow and potentially cause a dangerous and uncontrollable flame. Therefore, it is important to always turn off the oxygen first to ensure safety.

    Rate this question:

  • 12. 

    Oxygen line pressure should be what psi?

    • 5

    • 10

    • 15

    Correct Answer
    A. 10
    Explanation
    The correct answer is 10 psi because this is the recommended pressure for oxygen line. This pressure ensures that the oxygen is delivered at an appropriate flow rate and is safe for use. Higher pressures can cause damage to the equipment or result in an excessive flow of oxygen, while lower pressures may not deliver enough oxygen for the intended purpose. Therefore, maintaining a pressure of 10 psi is crucial for the proper functioning and safety of the oxygen line.

    List the correct safety gear required when using the oxyacetylene torch

    • Safety Glasses

    • Leather Gloves

    • Long Pants and shoes covering your foot

    • Welding Mask

    Correct Answer(s)
    A. Safety Glasses
    A. Leather Gloves
    A. Long Pants and shoes covering your foot
    Explanation
    The correct safety gear required when using the oxyacetylene torch includes safety glasses, leather gloves, and long pants and shoes that cover the foot. Safety glasses protect the eyes from sparks and debris, leather gloves provide hand protection from burns and cuts, and long pants and shoes covering the foot protect against potential burns and injuries from falling objects.
