What is the *primary* control? | A) Wear a hard hat <br>B) Use a spotter <br>C) Install a barricade <br>D) Keep the jackhammer on a tripod | **C** | Barricades keep traffic away from the work zone. |\n| 4 | **Struck\u2011By** \u2013 Which PPE protects against struck\u2011by hazards? | A) Steel\u2011toe boots <br>B) Hard hat <br>C) High\u2011visibility vest <br>D) All of the above | **D** | All listed items reduce injury from struck\u2011by incidents. |\n| 5 | **Caught\u2011In/Between** \u2013 While digging a trench, a worker is at risk of being caught in the trench. Which action *prevents* this hazard? | A) Use a trench shield <br>B) Wear a hard hat <br>C) Keep the trench 4\u202fft deep <br>D) Work only during daylight | **A** | Trench shields support the trench walls and prevent collapse. |\n| 6 | **Caught\u2011In/Between** \u2013 What is the *first* step in the lock\u2011out/tag\u2011out procedure? | A) Disconnect power <br>B) Place a tag <br>C) Test the equipment <br>D) Notify the supervisor | **A** | Disconnecting the energy source is the first safety step. |\n| 7 | **Electrocution** \u2013 A worker is using a 120\u2011V drill near a wet area. Which control *reduces* the electrocution risk? | A) Use a grounded outlet <br>B) Use a 240\u2011V drill <br>C) Wear rubber gloves <br>D) Keep the drill 6\u202fft from the ground | **A** | Grounding prevents stray voltage from causing shock. |\n| 8 | **Electrocution** \u2013 OSHA requires that all electrical work be performed by a *qualified* individual. What does \u201cqualified\u201d mean? | A) Has a high school diploma <br>B) Holds a valid electrician\u2019s license <br>C) Has 2\u202fyears of experience <br>D) Completed a safety course | **B** | A qualified electrician is licensed and trained to handle electrical work. |\n\n---\n\n## 5. Quick Group Scenario (2\u202fmin discussion + 1\u202fmin presentation)\n\n**Scenario Title:** *\u201cThe 20\u2011Foot Scaffold\u201d*\n\n> **Background:**  \n> A crew is about to install a 20\u2011foot scaffold on the roof of a new office building. The scaffold will support a crew of 4 workers and a 1\u2011ton crane that will lift materials onto the platform. The site is adjacent to a busy street, and a power line runs 10\u202fft above the scaffold.  \n>  \n> **Task:**  \n> 1. Identify **at least one** fall, struck\u2011by, caught\u2011in/between, and electrocution hazard in this situation.  \n> 2. Propose a *control* for each hazard.  \n> 3. Explain why your control is effective.\n\n**Instructions for Students:**  \n- Form groups of 3\u20134.  \n- Use a sticky note or index card to jot down each hazard and control.  \n- After 2\u202fmin, each group shares one hazard + control (1\u202fmin total).\n\n**Answer Key (for teacher reference):**\n\n| Hazard | Example | Control | Why It Works |\n|--------|---------|---------|--------------|\n| **Falls** | Workers climbing the scaffold. | Install guardrails and use a fall\u2011protection system (harness + lanyard). | Prevents falls from height and provides a backup if a fall occurs. |\n| **Struck\u2011By** | Crane moving on the street. | Establish a traffic control zone with barricades and a spotter. | Keeps vehicles and pedestrians away from the crane\u2019s path. |\n| **Caught\u2011In/Between** | Crane\u2019s moving parts. | Use machine guarding and lock\u2011out/tag\u2011out during maintenance. | Prevents workers from getting caught in moving parts. |\n| **Electrocution** | Power line 10\u202fft above scaffold. | Maintain a minimum clearance of 10\u202fft, use insulated tools, and keep the crane\u2019s electrical equipment de\u2011energized. | Keeps workers out of the hazardous voltage zone and reduces shock risk. |\n\n---\n\n## 6. Teacher Notes & Tips\n\n- **Engage Quickly:** Start with the \u201cName One Hazard\u201d round to get students talking and to gauge their baseline knowledge.\n- **Use Visuals:** If time permits, flash a quick slide or photo of each hazard type before the questions.\n- **Keep It Interactive:** Encourage students to discuss answers in pairs before sharing with the class.\n- **Scenario Flexibility:** If you have more time, let groups write a short safety plan or create a poster summarizing the controls.\n- **Assessment:** Use the answer key to give quick feedback. Highlight any misconceptions that arise during discussion.\n\n---\n\n**Good luck, and stay safe on the job!**", "finish_reason": "stop", "usage": {"queue_time": 0.114127678, "prompt_tokens": 151, "prompt_time": 0.0074212, "completion_tokens": 2133, "completion_time": 2.56198128, "total_tokens": 2284, "total_time": 2.56940248, "completion_tokens_details": {"reasoning_tokens": 375}}}
