  "examTitle": "Day 2: Manual Handling & Working at Height",
  "questions": [
    {
      "q": "What is the first step you should take before performing manual handling?",
      "options": ["Assess if the task can be avoided", "Assess the weight", "Warm up", "Ask for a team lift"],
      "correct": 0,
      "explanation": "According to the Manual Handling Operations Regulations, the absolute priority is always to avoid manual handling tasks completely if reasonably practicable (e.g., by automated machinery or delivering straight to the point of use)."
    },
    {
      "q": "When lifting from the floor, how should your feet be positioned?",
      "options": ["Tightly together", "Stable and shoulder-width apart", "One foot on a stool", "As far apart as possible"],
      "correct": 1,
      "explanation": "A stable base is vital. Feet should be apart (roughly shoulder-width) with one foot slightly forward to maintain balance and optimal body leverage throughout the lifting motion."
    },
    {
      "q": "Which part of the body is most likely to suffer long-term damage from poor lifting?",
      "options": ["Lungs", "Lower back", "Ears", "Eyes"],
      "correct": 1,
      "explanation": "Incorrect lifting posture shifts heavy compressive loads onto the spine, frequently resulting in long-term muscular strains, disc herniation, and chronic lower back pain."
    },
    {
      "q": "What should you do if a load is too heavy for one person?",
      "options": ["Lift quickly", "Drag it", "Seek assistance or use a mechanical aid", "Twist your body for leverage"],
      "correct": 2,
      "explanation": "If a load exceeds safe individual guidelines, workers must never attempt to lift it alone. They should use a mechanical handling device (like a pump truck or trolley) or coordinate a team lift."
    },
    {
      "q": "What is the main risk when working on a ladder?",
      "options": ["Fatigue", "Falling from height", "Getting dirty", "Being seen by the public"],
      "correct": 1,
      "explanation": "Because portable leaning or step ladders lack built-in protective edge barriers, falling from height remains the primary risk of severe injury or death."
    },
    {
      "q": "What is the 'three-point contact' rule for ladders?",
      "options": ["Three people holding it", "Three tools touching it", "Two hands/one foot or two feet/one hand", "Ladder touching the wall at three points"],
      "correct": 2,
      "explanation": "To maintain optimal stability when climbing or working on a ladder, you must keep three points of contact on the rungs/stiles at all times: two hands and one foot, or two feet and one hand."
    },
    {
      "q": "What prevents people from falling off an edge?",
      "options": ["Yellow paint", "Guardrails and toe boards", "Warning signs", "A pile of sand"],
      "correct": 1,
      "explanation": "Collective protection controls, like fixed guardrails (main rails and intermediate rails) and toe boards, provide a physical perimeter barrier to stop operatives from falling over an exposed edge."
    },
    {
      "q": "Who must inspect a scaffold before it is used?",
      "options": ["Newest worker", "A competent and trained person", "Anyone needing it", "The client"],
      "correct": 1,
      "explanation": "Scaffolding structures must only be inspected by an explicitly competent person (trained and certified under CISRS rules) before first use, after alterations, following severe weather, or at minimum every 7 days."
    },
    {
      "q": "What is the primary danger near a deep excavation?",
      "options": ["Buried treasure", "Sides collapsing", "Muddy boots", "Losing tools"],
      "correct": 1,
      "explanation": "Excavation sides can cave in unexpectedly without warning. Trench support shoring, battering back the soil angle, or installing trench boxes are mandatory to prevent crushing injuries."
    },
    {
      "q": "Why should you never throw tools up to a colleague at height?",
      "options": ["Bad luck", "Scratching the tool", "The tool could fall and cause injury", "Too much noise"],
      "correct": 2,
      "explanation": "Throwing tools increases the probability of drops, which can inflict devastating head or crush injuries on individuals below. Tools should always be hoisted securely using a line, tool bag, or gin wheel."
    },
    {
      "q": "What is the correct angle for a leaning ladder (ratio)?",
      "options": ["1 in 4 rule (75 degrees)", "1 in 1 rule", "1 in 10 rule", "Whatever feels comfortable"],
      "correct": 0,
      "explanation": "Leaning ladders must be set at an angle of 75 degrees. Applying the 1-in-4 rule ensures this layout: position the base 1 unit away from the wall for every 4 vertical units of height."
    },
    {
      "q": "Which is a risk factor related to the 'Load' in manual handling?",
      "options": ["Slippery floor", "Sharp edges or heat", "Worker's bad back", "Poor lighting"],
      "correct": 1,
      "explanation": "Characteristics directly inherent to the material itself—such as sharp edges, hot temperatures, lack of handholds, or shifting centers of gravity—are classified as 'Load' risk factors."
    },
    {
      "q": "What stops a mobile tower scaffold from tipping?",
      "options": ["Stabilizers/outriggers", "Heavy tools at the top", "Duct tape on wheels", "A worker holding it"],
      "correct": 0,
      "explanation": "Stabilizers or outriggers widen the base footprint of a mobile tower scaffold, drastically reducing the risk of tipping over when wind forces or lateral work movements are applied."
    },
    {
      "q": "Why is 'twisting' the spine dangerous during a lift?",
      "options": ["Takes longer", "Spine is weakest when twisting under load", "Causes dizziness", "Unprofessional"],
      "correct": 1,
      "explanation": "The human spine is biomechanically vulnerable to torsional stress. Twisting while supporting a heavy load concentrates pressure unevenly on the spinal discs, maximizing injury risk."
    },
    {
      "q": "How far must a ladder extend above a landing point?",
      "options": ["1 meter (about 3 rungs)", "10 centimeters", "Exactly level", "3 meters"],
      "correct": 0,
      "explanation": "To enable a safe handhold transition from the ladder to a working platform, the ladder stiles must extend at least 1 meter (roughly 3 rungs) above the landing point unless alternative handholds are fitted."
    },
    {
      "q": "What does the 'T' in TILE stand for?",
      "options": ["Time", "Task", "Team", "Tools"],
      "correct": 1,
      "explanation": "TILE is an ergonomic acronym used to memorize the key manual handling risk factors: **T**ask, **I**ndividual capability, **L**oad, and **E**nvironment."
    },
    {
      "q": "When is it safe to move a mobile tower with a worker on it?",
      "options": ["Holding on tight", "Moved less than 1m", "Never", "Flat ground only"],
      "correct": 2,
      "explanation": "Moving a mobile scaffold tower while an operative remains on the platform is strictly illegal. The force of moving can trigger tower imbalance or throw the individual over the guardrails."
    },
    {
      "q": "What is the purpose of a toe board?",
      "options": ["Keep feet warm", "Stop tools being kicked off edge", "Show where to stand", "Strengthen floorboards"],
      "correct": 1,
      "explanation": "Toe boards are solid perimeter barriers placed flat along the base of working platforms. Their structural purpose is to prevent loose bricks, tools, or materials from being kicked over the edge."
    },
    {
      "q": "Where should a load be held relative to the body?",
      "options": ["Arm's length", "Close to the waist", "On one shoulder", "As high as possible"],
      "correct": 1,
      "explanation": "Keeping a load close to your waist minimizes the forward extension leverage on your spine, reducing muscle fatigue and lower back strain significantly."
    },
    {
      "q": "What do you do if a ladder rung is cracked?",
      "options": ["Tape it", "Use carefully", "Tag 'Do Not Use' and report", "Skip that rung"],
      "correct": 2,
      "explanation": "Damaged structural components compromise overall load capacity. It must immediately be quarantined, marked with a 'Do Not Use' tag, taken out of service, and reported."
    },
    {
      "q": "What is a 'Fall Arrest' system purpose?",
      "options": ["Prevent a fall", "Catch a falling person safely", "Help climbing", "Hang tools"],
      "correct": 1,
      "explanation": "Unlike fall prevention equipment (which restricts you from reaching an edge), a Fall Arrest system (safety harness with an energy-absorbing lanyard) allows a fall to occur but safely decelerates and catches the worker mid-air."
    },
    {
      "q": "Why keep a site tidy to prevent falls?",
      "options": ["Appearance", "Reduce trip hazards near edges", "Save money", "Find tools"],
      "correct": 1,
      "explanation": "Stumbling or tripping over materials near working edges significantly raises the risk of falling over safety barriers or through floor openings."
    },
    {
      "q": "Who leads a team lift?",
      "options": ["Both people shouting", "Strongest person", "One designated coordinator", "Site manager in office"],
      "correct": 2,
      "explanation": "Team lifts require precise execution. One designated handler must coordinate the actions, instructing exactly when to lift, turn, and set down the material together."
    },
    {
      "q": "What spreads a scaffold's weight on soft ground?",
      "options": ["Sole boards", "Cardboard", "Plastic", "Bricks"],
      "correct": 0,
      "explanation": "Scaffold standards must be set on base plates resting on timber sole boards. This layout distributes the immense weight evenly across a wider area, preventing the scaffold from sinking into soft ground."
    },
    {
      "q": "What is 'individual capability'?",
      "options": ["Everyone lifts same", "Health/strength factors of the person", "Only for workers over 60", "Motivation"],
      "correct": 1,
      "explanation": "Individual capability refers to the unique physical tolerances, health constraints, strength levels, training background, and gender/age-related variances of the specific worker lifting."
    },
    {
      "q": "What is a 'fragile surface'?",
      "options": ["Cracks if hit", "Breaks if stood on (e.g., skylight)", "Wet surface", "Painted wall"],
      "correct": 1,
      "explanation": "A fragile surface is any roof sheeting, cladding, assembly, or skylight that cannot safely support the weight of a person and their tools, fracturing easily under pressure."
    },
    {
      "q": "Why ban 'homemade' ladders?",
      "options": ["Look bad", "Not tested to safety standards", "Wrong color", "Expensive"],
      "correct": 1,
      "explanation": "Ladders on construction sites must comply with rigorous design manufacturing criteria (BS EN 131) to guarantee structural load capability. Non-standard homemade options can split or fail instantly."
    },
    {
      "q": "Risk of repetitive manual handling?",
      "options": ["Boredom", "Upper Limb Disorders/chronic strain", "Uses electricity", "Finishes early"],
      "correct": 1,
      "explanation": "Repeating identical handling movements for extended periods triggers chronic strain on muscles and tendons, leading to Work-Related Upper Limb Disorders (WRULDs)."
    },
    {
      "q": "Purpose of a 'crawling board' on a roof?",
      "options": ["Cleanliness", "Spread worker's weight", "Place to sit", "Waterproofing"],
      "correct": 1,
      "explanation": "Crawling boards or roof ladders cross multiple support beams over fragile structures, safely spreading the operative's mass over a wider surface to prevent falls."
    },
    {
      "q": "What happens to a harness after a fall arrest?",
      "options": ["Clean it", "Destroy and replace", "Give to junior", "Shorten straps"],
      "correct": 1,
      "explanation": "The shock load forces of absorbing a human fall stretch and fatigue safety harness webbing and stitching. The equipment must be removed from service immediately and permanently destroyed."
    },
    {
      "q": "Safest way to move heavy loads long distance?",
      "options": ["Hand carry", "Mechanical aid (trolley)", "Team lift", "Roll it"],
      "correct": 1,
      "explanation": "Using a mechanical handling tool (e.g., forklift, sack truck, block splitter trolley) eliminates or minimizes the direct force applied to the human body, providing the safest transit method."
    },
    {
      "q": "What to do if wind increases while on a roof?",
      "options": ["Work faster", "Lie flat", "Stop work and descend", "Tie to chimney"],
      "correct": 2,
      "explanation": "High winds jeopardize equilibrium, generate unpredictable aerodynamic lift on roofing materials, and destabilize access equipment. Work must be suspended until wind speeds drop below safety parameters."
    },
    {
      "q": "Step ladder safety requirement?",
      "options": ["Fully open and locked", "Leaned while folded", "Bright color", "Stand on top step"],
      "correct": 0,
      "explanation": "Step ladders must be fully extended with locking mechanisms completely engaged before stepping onto them to prevent internal framework buckling or tipping."
    },
    {
      "q": "What is an 'Exclusion Zone' for?",
      "options": ["Cleaning area", "Prevent being hit by falling objects", "Tool storage", "Hide work"],
      "correct": 1,
      "explanation": "An exclusion zone uses physical barriers to close off an area directly beneath work at height, ensuring nobody walks inside the line of trajectory of a dropped object."
    },
    {
      "q": "What does 'L' in TILE stand for?",
      "options": ["Level", "Load", "Length", "Lifting"],
      "correct": 1,
      "explanation": "The 'L' stands for Load—requiring evaluation of structural qualities like weight, bulkiness, temperature, or dynamic stability before lifting."
    },
    {
      "q": "Why check ground before using a MEWP?",
      "options": ["Tire cleanliness", "Ground support/stability", "Parking", "Level for painting"],
      "correct": 1,
      "explanation": "MEWPs push intense point loads down onto the earth via outriggers or wheels. Checking ground stability protects against hidden structural voids or soft soils collapsing under the machine's mass."
    },
    {
      "q": "How to stop in a team lift?",
      "options": ["Drop immediately", "Communicate and set down together", "Keep going", "Let partner take weight"],
      "correct": 1,
      "explanation": "Handlers must communicate verbally to lower and ground the material symmetrically, protecting against sudden weight distribution shifts that can twist a partner's spine."
    },
    {
      "q": "What should NEVER be a working platform?",
      "options": ["Certified scaffold", "Pallets or buckets", "Scissor lift", "Podium step"],
      "correct": 1,
      "explanation": "Improvised equipment (like balancing on upturned buckets or a pallet lifted on a forklift) lacks mandatory safety guardrails or stability design, which violates the Work at Height Regulations."
    },
    {
      "q": "Danger of over-reaching on a ladder?",
      "options": ["Muscle strain", "Ladder tipping/falling", "Paint on clothes", "Slow work"],
      "correct": 1,
      "explanation": "Leaning your torso completely past the outer ladder stiles skews your center of gravity outside the support base, causing the entire ladder to slide out or tip sideways."
    },
    {
      "q": "Who provides PPE for height work?",
      "options": ["The worker", "The employer", "The government", "Manufacturer"],
      "correct": 1,
      "explanation": "Under the Personal Protective Equipment at Work Regulations, your employer is legally bound to source, pay for, and distribute all essential fall protection equipment (like harnesses and anchor ropes) free of cost."
