  "questions": [
    { "q": "What is the primary law governing health and safety at work in Great Britain?", "options": ["Health and Safety at Work Act 1974", "The Construction Act 2015", "The Road Traffic Act", "The Workers Rights Act"], "correct": 0, "explanation": "The Health and Safety at Work etc. Act 1974 (HASAWA) serves as the primary statutory framework framework for workplace safety, establishing binding requirements across all UK industries." },
    { "q": "In the 'Hierarchy of Control', which is the most effective method?", "options": ["Elimination", "Personal Protective Equipment", "Administrative controls", "Engineering controls"], "correct": 0, "explanation": "Elimination completely removes the hazard from the environment, dropping the associated risk level to zero. This makes it much more reliable than relying on human behavior or defensive protective gear." },

    { "q": "Which extinguisher should NEVER be used on an electrical fire?", "options": ["Water (Red label)", "CO2 (Black label)", "Dry Powder (Blue label)", "All are safe"], "correct": 0, "explanation": "Standard Water extinguishers must never be sprayed onto live electrical circuits. Because water conducts current rapidly, the electricity can jump straight back up the stream to shock the handler." },
    { "q": "What is a 'Near Miss'?", "options": ["An event that could have caused an injury but didn't", "A small injury", "A missed deadline", "A tool falling into water"], "correct": 0, "explanation": "A near miss is an unplanned incident that resulted in zero physical injuries or damage this time, but carried the clear potential to do so if conditions had been slightly different." },

They signify activities or entry paths that are strictly forbidden on site." },
    { "q": "Why should you keep your work area tidy?", "options": ["To prevent slips and trips", "To save space", "To please the manager", "To prevent rain damage"], "correct": 0, "explanation": "Good site housekeeping clears away loose packaging materials, debris, and trailing wires, removing the top source of non-fatal construction accidents: low-level slips and trips." },
    { "q": "What is 'asbestosis'?", "options": ["A chronic lung disease caused by asbestos fibers", "A skin rash", "An eye infection", "A type of headache"], "correct": 0, "explanation": "Asbestosis is a permanent, progressive scarring of the lung tissue caused by inhaling airborne asbestos fibers, resulting in severe chronic breathing difficulties." },
    { "q": "What color is a Mandatory sign (e.g., 'Wear Eye Protection')?", "options": ["Blue with a white symbol", "Yellow with a black symbol", "Red and white", "Green and white"], "correct": 0, "explanation": "Mandatory signs require specific actions to be taken.

    { "q": "If a tool has a 'Do Not Use' tag, what should you do?", "options": ["Leave it alone and report it", "Use it carefully", "Try to fix it yourself", "Take the tag off"], "correct": 0, "explanation": "A hazard tag indicates the tool is defective or unsafe. Operatives must leave the tool alone, avoid removing the tag, and report it immediately so it can be safely quarantined." },
    { "q": "What is the main danger of reversing vehicles on a site?", "options": ["People being struck in blind spots", "The noise", "Wasting fuel", "The dust"], "correct": 0, "explanation": "Large site trucks and tippers feature expansive visibility blind spots at the rear. Reversing without clear sightlines creates a severe hazard of striking or crushing blind ground workers." },
    { "q": "What is the purpose of a 'Banksman'?", "options": ["To guide a driver during maneuvering", "To count the bricks", "To pay the wages", "To clean the trucks"], "correct": 0, "explanation": "A Banksman acts as a trained spotter using standardized hand signals to guide plant machinery operators safely through blind spots or restricted site spaces." },

    { "q": "What should be used to stop tools falling from a scaffold?", "options": ["Toe boards and brick guards", "Yellow tape", "A warning sign", "Plastic wrap"], "correct": 0, "explanation": "Solid timber toe boards along with wire mesh brick guards enclose the working platform perimeter, physically stopping heavy tools or loose masonry from dropping onto individuals down below." },
    { "q": "Which sign color is used for emergency exits and first aid?", "options": ["Green", "Blue", "Red", "Yellow"], "correct": 0, "explanation": "Safe Condition markers—including fire assembly exit routes and emergency aid kits—are legally required to be green rectangular or square signs with clean white symbols." },
    { "q": "What is the 'latent period' of a disease?", "options": ["The time between exposure and symptoms appearing", "The time it takes to catch the disease", "The recovery time", "The length of the illness"], "correct": 0, "explanation": "The latency period represents the silent timeline gap between original contact with a toxin (such as asbestos) and the eventual clinical appearance of severe physical symptoms." },

    { "q": "What is the main danger of Carbon Monoxide?", "options": ["It is a poisonous gas that you cannot smell", "It is very loud", "It is very cold", "It causes trips"], "correct": 0, "explanation": "Carbon Monoxide (CO) is a deadly, toxic exhaust gas that is completely colorless and odorless. It starves the blood of oxygen silently, making it critical to run generators outdoors." },
    { "q": "How should you treat a minor cut on site?", "options": ["Clean it and apply a sterile dressing", "Cover it with electrical tape", "Wash it with oil", "Ignore it"], "correct": 0, "explanation": "Minor cuts must be cleaned gently under safe water parameters and wrapped in a sterile dressing. This acts as a barrier to keep toxic construction dust or biological bacteria out of the bloodstream." },
    { "q": "What is a 'Toolbox Talk'?", "options": ["A short site safety briefing", "A box of hammers", "A meeting about pay", "A talk about tools only"], "correct": 0, "explanation": "A Toolbox Talk is a brief, focused 10-to-15 minute interactive safety briefing used to refresh site teams on localized hazards or specific workplace regulations." },
