Write the letter of the correct answer for each multiple\u2011choice question.  \n2. Write **T** for True or **F** for False for the true/false statements.  \n3. You may use the space below each question for your answer, but keep the answer sheet separate from the quiz for grading.  \n\n---\n\n### Multiple\u2011Choice (choose one)\n\n1. **Which of the following is the minimum recommended shade number for viewing the arc when welding with SMAW?**  \n   A. Shade\u202f3  \n   B. Shade\u202f5  \n   C. Shade\u202f7  \n   D. Shade\u202f9  \n\n2. **When welding with an oxy\u2011fuel torch, the proper order for lighting the torch is:**  \n   A. Open the oxygen valve, then the fuel gas valve, and ignite with a spark lighter.  \n   B. Open the fuel gas valve, then the oxygen valve, and ignite with a spark lighter.  \n   C. Open the fuel gas valve, ignite, then slowly open the oxygen valve.  \n   D. Open the oxygen valve, ignite, then slowly open the fuel gas valve.  \n\n3. **Which piece of personal protective equipment (PPE) is NOT required for stick welding?**  \n   A. Flame\u2011resistant welding jacket  \n   B. Leather welding gloves  \n   C. Safety glasses with clear lenses  \n   D. Steel\u2011toed safety boots  \n\n4. **The best way to control welding fumes in a classroom shop is to:**  \n   A. Open all doors and windows for cross\u2011draft ventilation.  \n   B. Use a local exhaust ventilation (LEV) hood positioned close to the weld pool.  \n   C. Wear a disposable paper mask over the face.  \n   D. Turn on a ceiling fan to circulate air.  \n\n5. **Which of the following is a correct practice when moving a full\u2011size oxygen cylinder?**  \n   A. Drag it across the floor on its valve.  \n   B. Roll it on its wheels while keeping the valve protected with a cap.  \n   C. Carry it upright in one hand.  \n   D. Store it horizontally on the floor.  \n\n6. **During welding, an electric shock hazard can be reduced by:**  \n   A. Wearing rubber gloves and standing on a wet floor.  \n   B. Using a grounded welding machine and keeping the workpiece dry.  \n   C. Removing the ground clamp from the workpiece.  \n   D. Wearing only a leather jacket and no other PPE.  \n\n---\n\n### True / False (write **T** or **F**)\n\n7. **A fire watch must remain in the area for at least 30\u202fminutes after welding is completed, even if no sparks are observed.**  \n\n8. **The recommended shade number for oxy\u2011acetylene welding is the same as for SMAW (stick) welding.**  \n\n9. **It is safe to store oxygen and acetylene cylinders side\u2011by\u2011side without any separation.**  \n\n10. **If a welding electrode breaks and the metal core is exposed, you should continue welding until the break is finished.**  \n\n---\n\n## Answer Key & Explanations  \n\n| # | Answer | Explanation |\n|---|--------|-------------|\n| 1 | **C \u2013 Shade\u202f7** | For most SMAW applications the minimum is Shade\u202f7; darker shades (8\u201110) are used for higher currents. |\n| 2 | **C \u2013 Open the fuel gas valve, ignite, then slowly open the oxygen valve** | This \u201cfuel\u2011first\u201d method prevents flashback and gives a stable flame. |\n| 3 | **C \u2013 Safety glasses with clear lenses** | Clear lenses do not protect against the intense UV/IR radiation; welding goggles or a filter lens of the proper shade are required. |\n| 4 | **B \u2013 Use a local exhaust ventilation (LEV) hood positioned close to the weld pool** | LEV captures fumes at the source and is far more effective than general room ventilation. |\n| 5 | **B \u2013 Roll it on its wheels while keeping the valve protected with a cap** | Cylinders must be moved on wheels, never dragged; valve caps protect against damage and accidental opening. |\n| 6 | **B \u2013 Using a grounded welding machine and keeping the workpiece dry** | Proper grounding and a dry work environment greatly reduce shock risk. |\n| 7 | **T** | A fire watch must stay for at least 30\u202fmin (or per local code) to detect and extinguish any hidden fires. |\n| 8 | **F** | Oxy\u2011acetylene welding typically requires a darker shade (Shade\u202f9\u201110) because of the brighter flame. |\n| 9 | **F** | Oxygen and acetylene must be stored separately (minimum 20\u202fft apart) and upright to prevent fire or explosion. |\n|10 | **F** | A broken electrode can expose the metal core, creating a fire hazard; stop welding, replace the electrode, and inspect the area. |\n\n**Scoring:** 1 point per correct answer. 8\u201110 = Excellent, 5\u20117 = Needs Review, 0\u20114 = Redo the safety lesson.  \n\n---  \n\n*Feel free to copy this quiz onto a worksheet, project it on the board, or use it as a digital form for your students.*", "finish_reason": "stop", "usage": {"queue_time": 0.243332328, "prompt_tokens": 156, "prompt_time": 0.006186509, "completion_tokens": 1325, "completion_time": 2.7613334739999997, "total_tokens": 1481, "total_time": 2.767519983, "completion_tokens_details": {"reasoning_tokens": 181}}}
