These four cause most construction deaths and are a required part of every OSHA 10-Hour Construction course.\nSegment\nTime\nFormat\nWarm-up recap\n2 min\nWhole class\nReview questions\n7 min\nIndividual or pairs\nGroup scenario\n5 min\nTeams of 3\u20134\nWrap-up\n1 min\nWhole class\nMaterials: printed questions (or projected), scrap paper per team, timer.\nWarm-up recap (2 min)\nAsk the class to name the Focus Four out loud, then give one example and one control for each. Fill gaps using the table.\nHazard\nWhat it means\nExample\nKey controls\nFalls\nFalling to a lower level\nUnprotected roof edge, open floor hole\nGuardrails, covers, personal fall arrest at 6 ft or more\nStruck-by\nHit by a moving, flying, falling, or swinging object\nBacking dump truck, dropped tool\nHard hats, hi-vis vests, toe boards, stay clear of loads\nCaught-in/between\nCrushed, pinched, or buried between objects\nTrench cave-in, unguarded gears\nTrench protective systems, machine guards, lockout/tagout\nElectrocution\nContact with electrical energy\nOverhead power lines, damaged cords\n10 ft clearance from lines, GFCIs, inspect cords and tools\nReview questions (7 min)\nStudents answer on paper, then the class checks against the answer key.\n1. Falls: In construction, at what height above a lower level must workers be protected from falls?\n    \u25e6 A) 4 ft  B) 6 ft  C) 10 ft  D) 15 ft\n2. Falls: When an extension ladder is used to reach a roof, how far must the side rails extend above the landing?\n3. Struck-by: A dump truck is backing up near you. Name two things you should do to avoid being struck.\n4. Struck-by: Why are toe boards installed along guardrails on scaffolds and elevated platforms?\n5. Caught-in/between: At what depth does a trench require a protective system (sloping, shoring, or a trench box), unless it is entirely in stable rock?\n    \u25e6 A) 3 ft  B) 4 ft  C) 5 ft  D) 8 ft\n6. Caught-in/between: How far back from the trench edge must the excavated dirt (spoil pile) and equipment be kept?\n7. Electrocution: What is the minimum safe distance to keep equipment and materials away from overhead power lines up to 50 kV?\n8. Electrocution: What does a GFCI (ground-fault circuit interrupter) do, and why is it required on construction sites?\nGroup scenario: Hazard Hunt (5 min)\nRead the scene aloud. Each team has 3 minutes to find one hazard for each of the Focus Four and name a fix for each. Teams then share for 2 minutes; one point per correct hazard, one per correct fix.\nA crew is building a two-story addition on a house. A worker on the second floor is cutting plywood next to an open floor hole with no cover. Two others are on the flat roof framing the edge, with no guardrail and no harnesses. Below, a skid steer is backing up to move lumber, and a laborer is walking behind it looking at his phone. Along the side of the house, a 6-ft-deep utility trench has straight vertical walls and no trench box, with the dirt piled right at the edge. A worker in the trench is running a saw plugged into an extension cord with a missing ground prong. Above the driveway, the crew has parked an aerial lift about 5 ft from an overhead power line.\nAnswer key\n#\nAnswer\n1\nB) 6 ft. Guardrails, safety nets, or personal fall arrest systems are required at 6 ft or more.\n2\nAt least 3 ft above the landing. Bonus: set the base 1 ft out for every 4 ft of height (4:1 rule).\n3\nAny two: stay out of the blind spots, make eye contact with the operator, use a spotter, wear a hi-vis vest, never walk behind a backing vehicle.\n4\nTo keep tools and materials from falling off the edge and striking workers below.\n5\nC) 5 ft. Trenches 20 ft or deeper need a system designed by a registered professional engineer.\n6\nAt least 2 ft from the edge.\n7\n10 ft. Greater voltages need more distance.\n8\nIt senses current leaking to ground (for example, through a person) and shuts off power in a fraction of a second, preventing electrocution. Construction sites are often wet and use damaged cords, which raises shock risk.\nScenario answer key\nHazard\nFound in the scene\nFix\nFalls\nUncovered floor hole; roof edge with no guardrail or harness\nSecured, labeled hole cover; guardrails or personal fall arrest on the roof\nStruck-by\nLaborer behind a backing skid steer, distracted by his phone\nStay out of blind spots, use a spotter, put the phone away, wear hi-vis\nCaught-in/between\n6-ft trench with vertical walls, no protection, spoil at the edge\nTrench box, shoring, or sloping; spoil pile at least 2 ft back; worker out until protected\nElectrocution\nCord missing its ground prong; aerial lift 5 ft from a power line\nRemove the cord from service and use a GFCI; move the lift to at least 10 ft away\nWrap-up (1 min)\nAsk each student to name the one Focus Four hazard they think they would most likely face on their first job, and the control they'd use. Remind them: under OSHA, they have the right to a safe workplace and to speak up about hazards without retaliation.\n", "capture_note": "Claude's chat reply, then the Claude Docs document text as copied (tables copy as one cell per line; document links copy as plain text)"}
