4. Always use the following sequence and technique for lighting a torch __________
- A.
A before c
- B.
A before o
- C.
O before a
- D.
A before c
Correct Answer
B. A before oExplanation
The correct answer is "a before o" because it is stated twice in the given sequence and technique for lighting a torch. This implies that "a" should always come before "o" when lighting a torch. The repetition of this instruction reinforces the importance of following this specific order.Rate this question:

3. Treat __________ with respect. Do not turn valve handle using force.
- A.
Tanks
- B.
Regulators
- C.
Machine
- D.
Helmet
Correct Answer
B. RegulatorsExplanation
The correct answer is "regulators" because the sentence is talking about turning valve handles, which is typically associated with regulating the flow of something, such as gas or liquid. Tanks, machines, and helmets do not typically have valve handles that need to be turned, so they are not the correct answer.Rate this question:

2. Do not _______ a torch with a match or hot metal, or in a confined space. Use friction lighters or stationary pilot flames.
- A.
Clean
- B.
Fix
- C.
Light
- D.
Adjust
Correct Answer
C. LightExplanation
The correct answer is "light" because the sentence is advising against using a torch with a match or hot metal, or in a confined space. Instead, it suggests using friction lighters or stationary pilot flames. The word "light" here means to ignite or start the torch using an appropriate method, rather than cleaning, fixing, or adjusting it.Rate this question:

6. Cylinders should be kept at a safe distance from the ____________ operation so there will be little possibility of sparks, hot slag, or flames reaching them.
- A.
Machining
- B.
Welding
- C.
Designing
- D.
Computing
Correct Answer
B. WeldingExplanation
Cylinders should be kept at a safe distance from the welding operation to minimize the risk of sparks, hot slag, or flames reaching them. Welding involves the use of intense heat and open flames, which can pose a fire hazard if they come into contact with cylinders containing flammable gases. Therefore, it is important to maintain a safe distance between the cylinders and the welding operation to ensure the safety of the workplace.Rate this question:

5. Always use the following sequence and technique for shutting off a torch:
- A.
A before o
- B.
O before a
- C.
A before b
- D.
B before c
Correct Answer
A. A before oExplanation
The correct answer is "a before o" because the given sequence and technique for shutting off a torch states that "a" should be turned off before "o". This implies that "a" has a higher priority or importance than "o" in the shutting off process.Rate this question:

8. Always open the _______ slowly to avoid strain on the regulator gage. Do not stand in front of valves when opening them.
- A.
Valves
- B.
Safety diaphragm
- C.
Hose linkage
- D.
Cylinders
Correct Answer
A. ValvesExplanation
To avoid strain on the regulator gauge and for safety reasons, it is recommended to open the valves slowly. This gradual opening allows for better control and prevents sudden pressure surges that could damage the regulator gauge or cause accidents. Standing in front of valves when opening them is also discouraged to avoid potential harm in case of any unexpected releases of pressure or gas. Therefore, valves should always be opened slowly and with caution.Rate this question:

7. Do not open the acetylene valve more than one and one half turns. Never use acetylene at pressures in excess of _____ . Higher pressure can cause an explosion.
- A.
12 psi
- B.
15 psi
- C.
14 psi
- D.
15 lbs
Correct Answer
B. 15 psiExplanation
Acetylene should not be used at pressures higher than 15 psi because higher pressures can cause an explosion. It is important to follow this safety precaution to prevent any potential accidents or hazards.Rate this question:

9. Always turn the acetylene cylinder so the valve outlet will point _______ from the oxygen cylinder.
- A.
Towards
- B.
Away
- C.
East
- D.
West
Correct Answer
B. AwayExplanation
To ensure safety, it is important to turn the acetylene cylinder so that the valve outlet points away from the oxygen cylinder. This is because acetylene is a highly flammable gas, and if the valve outlet were to point towards the oxygen cylinder, it could potentially create a dangerous situation where the two gases mix and increase the risk of a fire or explosion. Therefore, it is crucial to always turn the acetylene cylinder in the opposite direction, away from the oxygen cylinder, to prevent any potential hazards.Rate this question:

10. When the oxygen cylinder is in use, open the valve to the _______ limit to prevent leakage around the valve stem.
- A.
Minimum
- B.
Almost maximum
- C.
Full
- D.
Specified
Correct Answer
C. FullExplanation
When the oxygen cylinder is in use, it is important to open the valve to the full limit in order to prevent any leakage around the valve stem. This ensures that the valve is fully open and allows the oxygen to flow without any obstruction or leakage. Opening the valve to the full limit also helps to maintain the pressure and flow rate of the oxygen, ensuring that it is delivered at the desired level. Therefore, opening the valve to the full limit is the correct approach to prevent any leakage and ensure proper functioning of the oxygen cylinder.Rate this question:

11. Always protect _______ from being walked on or run over. Avoid kinks and tangles.
- A.
Tanks
- B.
Hoses
- C.
Regulators
- D.
Torches
Correct Answer
B. HosesExplanation
Hoses should always be protected from being walked on or run over to prevent damage such as kinks and tangles. This is important because any damage to the hoses can lead to leaks or reduced functionality, affecting the flow of liquids or gases they are meant to transport. Protecting hoses ensures their longevity and proper functioning, avoiding potential accidents or disruptions in various applications where hoses are used.Rate this question:

12. Do not work with _________ over the shoulder, around the legs, or tied to the waist.
- A.
Regulators
- B.
Torches
- C.
Hoses
- D.
Tanks
Correct Answer
C. HosesExplanation
It is important not to work with hoses over the shoulder, around the legs, or tied to the waist because it can cause tripping hazards and restrict movement, increasing the risk of accidents and injuries. Working with hoses in these positions can also lead to kinks, twists, or damage to the hoses, which can affect the flow of gases or liquids and compromise the safety of the work environment. Therefore, it is best to ensure that hoses are properly positioned and secured to avoid any potential hazards.Rate this question:
