  "questions": [
    { "q": "What is the 'Last Resort' in the Hierarchy of Control?", "options": ["PPE", "Elimination", "Substitution", "Engineering Controls"], "correct": 0, "explanation": "PPE acts as the final line of defense because it only shields the individual worker and relies on perfect fit and human behavior, whereas higher controls actively remove or isolate the hazard entirely." },
    { "q": "What does COSHH stand for?", "options": ["Control of Substances Hazardous to Health", "Collection of Safety Hazards", "Construction of Safe Houses", "Care of Site Health"], "correct": 0, "explanation": "COSHH outlines the legal framework requiring employers to evaluate, monitor, and prevent worker exposure to chemicals, dusts, gases, and biological agents that can cause ill health." },
