    { "q": "Where should you go after hearing a fire alarm?", "options": ["The assembly point", "To your car", "To the canteen", "Under a scaffold"], "correct": 0, "explanation": "Once a fire alarm triggers, you must drop your tools immediately and exit via the designated escape routes to the muster assembly point to check in for the headcount roll call." },
    { "q": "Who takes charge during a medical emergency?", "options": ["A trained first aider", "The person with the loudest voice", "The youngest worker", "A passing driver"], "correct": 0, "explanation": "A trained, designated first-aider holds the appropriate knowledge to administer initial life-support care, manage basic injuries, and coordinate safely with professional emergency services." },
    { "q": "Why are accidents and near misses reported?", "options": ["To find the cause and prevent it", "To blame the worker", "To win a prize", "To fill office space"], "correct": 0, "explanation": "Documenting incidents allows safety teams to investigate and locate the underlying hazard or flaw in the system, taking corrective action before it leads to a serious or fatal injury." },
    { "q": "What is a 'Near Miss'?", "options": ["An incident that had the potential to cause injury", "A small scratch", "A completed task", "A late delivery"], "correct": 0, "explanation": "A near miss is an unplanned event that resulted in zero physical injuries or damage this time, but served as a clear warning indicator that an uncorrected hazard could cause an accident next time." },
    { "q": "What is the leading cause of fatal accidents in construction?", "options": ["Falls from height", "Electric shock", "Noise", "Vehicles"], "correct": 0, "explanation": "HSE safety statistics consistently confirm that falls from height remain the single biggest cause of fatal trauma and severe life-altering spinal/head injuries across the construction industry." },
    { "q": "Why is 'housekeeping' important for safety?", "options": ["It reduces slips, trips, and falls", "It makes the site look pretty", "It saves on storage", "It helps the grass grow"], "correct": 0, "explanation": "Keeping site walkways clear of loose timber, wrapping plastics, and trailing wires removes the primary environmental source of non-fatal construction accidents: slips, trips, and stumbles." },
    { "q": "What color is the label on a FOAM extinguisher?", "options": ["Cream", "Red", "Black", "Blue"], "correct": 0, "explanation": "Under British Standard BS EN 3, Foam (AFFF) extinguishers feature a distinctive Cream-colored indicator label band or block on their solid red cylinders." },
    { "q": "Which extinguisher has a BLACK label?", "options": ["CO2", "Water", "Foam", "Powder"], "correct": 0, "explanation": "A solid Black label or color block identifies a Carbon Dioxide (CO2) extinguisher, which is safe for knocking out live electrical fire risks without leaving messy chemical residues behind." },
    { "q": "What is Step 1 of the 'Five Steps to Risk Assessment'?", "options": ["Identify hazards", "Record findings", "Review assessment", "Evaluate risks"], "correct": 0, "explanation": "According to the HSE guidelines, Step 1 requires a systematic check of the workplace to identify what could reasonably be expected to cause physical injury or ill health (Identify the Hazards)." },
    { "q": "What is a legal duty of an employee?", "options": ["Take care of themselves and others", "Carry out all risk assessments", "Pay for their own hard hat", "Design safety signs"], "correct": 0, "explanation": "Section 7 of HASAWA legally requires employees to take reasonable care of the health and safety of themselves and any colleagues or visitors who may be affected by their acts at work." },

    { "q": "What is the correct angle for a ladder?", "options": ["75 degrees (1 in 4)", "45 degrees", "90 degrees", "10 degrees"], "correct": 0, "explanation": "Leaning ladders must be set at a safe 75-degree climbing angle. Applying the 1-in-4 rule ensures this balance: pull the base 1 unit outward for every 4 vertical units of elevation height." },
    { "q": "How many people should be on a ladder at once?", "options": ["One", "Two", "Three", "Four"], "correct": 0, "explanation": "Portable leaning or step ladders are structural tools designed strictly for single-person light work or access. Overloading a ladder with multiple workers destabilizes it and risks a sudden collapse." },
    { "q": "What is another name for a 'cherry picker'?", "options": ["MEWP", "Sack dumper", "Forklift", "Excavator"], "correct": 0, "explanation": "MEWP stands for Mobile Elevating Work Platform.

    { "q": "What should you do if you discover an accident?", "options": ["Ensure the area is safe", "Run away", "Take a video", "Start cleaning"], "correct": 0, "explanation": "Your first step must be to check the immediate environment to ensure it is fundamentally safe before entering, preventing yourself from becoming a secondary casualty of an un-isolated hazard." },
    { "q": "Final Question: If you are unsure how to do a task safely, what should you do?", "options": ["Stop and ask your supervisor", "Guess", "Watch a video", "Wait"], "correct": 0, "explanation": "If you encounter an unmapped hazard or lack appropriate technical training, you must pause immediately and request direction from your supervisor to maintain a safe system of work." },

    { "q": "Who is responsible for your safety at work?", "options": ["Both you and your employer", "Only the safety officer", "Only the government", "No one"], "correct": 0, "explanation": "Safety compliance is a mutual responsibility. Your corporate employer holds a legal duty to provide a secure environment, and you hold a legal duty to avoid reckless or unsafe acts." },
    { "q": "In the hierarchy of control, what is considered the 'Last Resort'?", "options": ["PPE", "Elimination", "Substitution", "Engineering controls"], "correct": 0, "explanation": "PPE sits at the bottom of the safety hierarchy. It only shields the individual worker and can fail or be fitted wrong, meaning it should only be used if hazards cannot be engineered out entirely." },
    { "q": "What color is the label on a DRY POWDER extinguisher?", "options": ["Blue", "Red", "Cream", "Black"], "correct": 0, "explanation": "A bold Blue label block or band signifies a Dry Powder extinguisher. It marks it as a versatile multi-purpose ABC-rated suppression tool." },
    { "q": "Which extinguisher is safe for live electrical fires?", "options": ["CO2", "Water", "Foam", "Wet cloth"], "correct": 0, "explanation": "Carbon Dioxide (CO2) is a non-conductive gas agent, allowing it to extinguish electrical fires cleanly and safely without exposing the operator to current or damaging wiring loops." },
    { "q": "What is 'Risk' defined as?", "options": ["The likelihood and severity of harm", "A dangerous tool", "A site inspection", "A near miss"], "correct": 0, "explanation": "Risk is a combination of two distinct evaluation variables: the likelihood (probability) that a hazard will manifest, and the severity (consequence) of that potential harm." }
