    { "q": "What is 'Substitution' in risk control?", "options": ["Using a safer material or tool", "Removing the tool entirely", "Working faster", "Hiring more workers"], "correct": 0, "explanation": "Substitution swaps out a heavy risk (like a volatile chemical cleaner) for a lower-hazard option (like a water-based alternative), eliminating the worst chemical risks safely." },
    { "q": "What is the 'last resort' in the hierarchy of control?", "options": ["Personal Protective Equipment (PPE)", "Elimination", "Substitution", "Engineering controls"], "correct": 0, "explanation": "PPE is the final line of defense because it only shields the individual operator and can fail, whereas higher controls actively remove or engineer the hazard out of the environment." },
    { "q": "Why are 'Toolbox Talks' important?", "options": ["They provide specific site safety briefings", "They are for eating lunch", "They are for fixing tools", "They are for planning parties"], "correct": 0, "explanation": "A Toolbox Talk is a brief, 10-to-15 minute interactive on-site safety briefing used to refresh teams on specific regulations or high-risk upcoming shifts." },

    { "q": "What is the purpose of an assembly point?", "options": ["To conduct a safe roll call", "To store materials", "To park site vehicles", "To have lunch"], "correct": 0, "explanation": "The muster assembly point provides a secure collection zone outside the hazard perimeter, allowing the fire warden to perform an accurate headcount against the log." },
    { "q": "Why is 'Zero Tolerance' for drugs/alcohol important?", "options": ["They cause poor judgement and increase risk", "They are too expensive", "They make people sleep", "They are against the lunch rules"], "correct": 0, "explanation": "Intoxicants warp risk assessment judgment, degrade spatial awareness, and slow physical response speeds, drastically increasing the risk of serious accidents." },
