Question 1CITB Health, safety and environment test

Under the Work at Height Regulations, at what height does work become 'work at height'?

  1. Only work on scaffolding or ladders
  2. Any height where a person could fall and be injured, including below head height Correct answer.
  3. Only work above 2 metres
  4. Only work above 4 metres

Explanation

The Work at Height Regulations apply to any place where a person could fall a distance liable to cause personal injury; there is no minimum height threshold. Even a fall from a low level can cause serious injury.

Question 2CITB Health, safety and environment test

What is the main purpose of a harness and lanyard when working on a roof?

  1. To arrest a fall and limit the distance fallen Correct answer.
  2. To warn others that work is in progress
  3. To provide a comfortable seating position
  4. To keep tools attached to the operative

Explanation

Personal fall protection systems such as harnesses and lanyards are designed to arrest a fall and limit the distance and forces involved. They are a last line of defence after collective measures.

Question 3CITB Health, safety and environment test

When should a roof edge protection system be inspected by a competent person?

  1. Only after an accident has occurred
  2. Only once when it is first installed
  3. Before first use, after any event likely to affect its stability, and at intervals not exceeding seven days Correct answer.
  4. Only when the client requests it

Explanation

Edge protection and other work equipment must be inspected before first use, after events that may affect stability, and at regular intervals (typically no more than seven days). This ensures defects are found before they cause harm.

Question 4CITB Health, safety and environment test

A roof worker is about to use a mobile elevating work platform (MEWP). Which check is most important before use?

  1. That the machine has a full tank of fuel
  2. That the machine is the newest model available
  3. That the operator holds the correct category of training and the machine has a current thorough examination Correct answer.
  4. That the weather forecast is dry for the whole day

Explanation

Operators of MEWPs must be trained for the specific machine type and the equipment must have a current thorough examination under LOLER. These are the key legal and safety pre-use checks.

Question 5CITB Health, safety and environment test

What does the term 'fragile roof' mean in relation to roof work?

  1. A roof with a steep pitch
  2. A roof that is old and may need replacing
  3. A roof covering or liner that will not safely support the weight of a person Correct answer.
  4. A roof made of metal sheeting

Explanation

A fragile roof is one where the covering or liner cannot safely support a person's weight and may fail without warning. Fragile surfaces require controls such as crawling boards, guard rails and warning signs.

Question 6CITB Health, safety and environment test

Which of the following is the most effective control for preventing falls when working on a roof?

  1. Issuing personal fall arrest harnesses to all workers
  2. Displaying warning signs at ground level
  3. Using a ladder instead of scaffolding
  4. Providing collective edge protection such as guard rails Correct answer.

Explanation

The hierarchy of control for work at height requires collective protection first, before personal fall protection. Guard rails protect everyone without relying on individual behaviour.

Question 7CITB Health, safety and environment test

When must a roof worker wear head protection?

  1. Only when working above 3 metres
  2. Where there is a risk of falling objects or head impact, including on sites where helmets are mandatory Correct answer.
  3. Only when the client is on site
  4. Only when using power tools

Explanation

Head protection is required wherever there is a risk of injury from falling objects or impact, and many sites make helmets mandatory. The duty is risk-based, not tied to a fixed height.

Question 8CITB Health, safety and environment test

A worker discovers a damaged roof ladder rung before starting work. What is the correct action?

  1. Repair it with tape and continue
  2. Use it carefully and report it at the end of the shift
  3. Stop using it, report it and ensure it is taken out of service Correct answer.
  4. Ask a colleague to hold the ladder steady while using it

Explanation

Defective work equipment must be taken out of service immediately and reported so it can be repaired or replaced. Continuing to use it puts the worker and others at risk.

Question 9CITB Health, safety and environment test

What is the correct way to secure a roof ladder on a pitched roof?

  1. Tie it to a chimney
  2. Lean it against the gutter
  3. Rest it on the eaves without fixing
  4. Hook it over the ridge so it cannot slip Correct answer.

Explanation

Roof ladders should be fitted with a ridge hook so they are secured over the ridge and cannot slip. This is the recognised method for safe access on pitched roofs.

Question 10CITB Health, safety and environment test

Which document sets out the safe system of work for a specific roof cladding task?

  1. A site newsletter
  2. A purchase order
  3. A method statement Correct answer.
  4. A holiday rota

Explanation

A method statement describes the sequence of work and the controls to be followed for a specific task. It forms part of the safe system of work.

Question 11CITB Health, safety and environment test

What is the purpose of a permit to work system for roof access?

  1. To provide a checklist for cleaning the site
  2. To order materials for the roof
  3. To formally authorise and control high-risk work and record the controls in place Correct answer.
  4. To record how many hours each worker has worked

Explanation

A permit to work is a formal control for high-risk activities, confirming that specified precautions are in place before work starts. It documents authorisation and conditions.

Question 12CITB Health, safety and environment test

Which of the following best describes the purpose of a tool box talk?

  1. A training course leading to a qualification
  2. A short briefing to communicate specific hazards and controls before work Correct answer.
  3. A formal disciplinary meeting
  4. A meeting to discuss pay and conditions

Explanation

Tool box talks are short, focused briefings on specific hazards and controls. They reinforce safe working and allow questions before work starts.

Question 13CITB Health, safety and environment test

What is the main risk from working on a roof in high winds?

  1. Reduced noise levels on site
  2. Improved grip on the roof surface
  3. Being blown off balance or having materials and sheets blown away Correct answer.
  4. Increased risk of sunburn

Explanation

High winds can destabilise workers and blow loose materials or cladding sheets away, creating fall and struck-by risks. Work should be stopped or reassessed when wind speeds are unsafe.

Question 14CITB Health, safety and environment test

A worker is fitting cladding sheets near overhead power lines. What is the key control?

  1. Maintain a safe distance and isolate or divert the supply where possible Correct answer.
  2. Work faster to reduce exposure time
  3. Use a longer fixing tool
  4. Wear rubber gloves

Explanation

Work near overhead lines requires maintaining a safe distance and, where possible, isolating or diverting the supply. This is the primary control to prevent electric shock.

Question 15CITB Health, safety and environment test

What does a risk assessment for roof cladding work primarily aim to do?

  1. Identify hazards and decide on controls to reduce risk to an acceptable level Correct answer.
  2. Record the workers' qualifications
  3. List all the tools needed for the job
  4. Calculate the cost of the project

Explanation

A risk assessment identifies hazards, evaluates the risk and sets out controls to reduce risk so far as is reasonably practicable. It is a decision-making tool, not a resource list.

Question 16CITB Health, safety and environment test

When should a roof worker report a near miss?

  1. Only at the end of the project
  2. Only if someone was injured
  3. Never, because no one was hurt
  4. As soon as possible after the event, so lessons can be learned Correct answer.

Explanation

Near misses are leading indicators of risk and should be reported promptly so the cause can be investigated and controls improved. Reporting only injuries misses valuable warning signs.

Question 17CITB Health, safety and environment test

Which of the following would be classified as a reportable incident under RIDDOR?

  1. A fall from height that results in a fracture Correct answer.
  2. A near miss with no injury
  3. A minor cut that needs a plaster
  4. A worker feeling tired at the end of a shift

Explanation

RIDDOR requires reporting of specified serious incidents, including fractures from falls from height. Minor injuries and near misses are recorded but are not reportable in the same way.

Question 18CITB Health, safety and environment test

What is the safest way to move cladding sheets on a roof?

  1. Use suitable lifting aids or team lifting and keep loads balanced Correct answer.
  2. Throw them to a colleague
  3. Carry them alone to save time
  4. Drag them across the roof surface

Explanation

Manual handling should be avoided where possible by using aids, and where lifting is necessary, team lifting and balanced loads reduce the risk of musculoskeletal injury.

Question 19CITB Health, safety and environment test

Which of these is a sign that a roof surface may be fragile?

  1. The roof has a shallow pitch
  2. The roof was installed by a large contractor
  3. The presence of rooflights or liner panels that are not load-bearing Correct answer.
  4. The roof is painted a light colour

Explanation

Rooflights and non-load-bearing liner panels are common fragile elements. Warning signs, drawings and surveys help identify them before access.

Question 20CITB Health, safety and environment test

What is the purpose of a safety net under a roof cladding operation?

  1. To shade workers from the sun
  2. To keep the site tidy
  3. To provide a walkway
  4. To catch a falling person or material and reduce injury Correct answer.

Explanation

Safety nets are a collective fall arrest measure designed to catch people or materials and reduce the consequences of a fall. They must be installed by competent persons.

Question 21CITB Health, safety and environment test

A worker is asked to work alone on a roof. What is the main concern?

  1. They will work more slowly
  2. They will need more materials
  3. They cannot use power tools
  4. If they are injured or trapped, there may be no one to raise the alarm or assist Correct answer.

Explanation

Lone working on a roof creates a serious risk because an injured or trapped worker may be unable to summon help. Arrangements for monitoring and emergency response must be in place.

Question 22CITB Health, safety and environment test

What should be done with waste cladding offcuts on a roof?

  1. Push them down the nearest downpipe
  2. Throw them off the edge into a skip
  3. Leave them on the roof until the end of the job
  4. Lower them safely or use debris netting; never throw them from height Correct answer.

Explanation

Materials must not be thrown from height because of the struck-by risk. Offcuts should be lowered safely or controlled with netting and removed properly.

Question 23CITB Health, safety and environment test

Which of these best describes the correct use of barriers around a roof work area?

  1. They can be removed as soon as work starts
  2. They keep people out of the danger zone below and are clearly signed Correct answer.
  3. They are only needed if the client asks
  4. They are only for decoration

Explanation

Barriers and signage create an exclusion zone below roof work to protect people from falling materials. They must be maintained for the duration of the work.

Question 24CITB Health, safety and environment test

A worker notices that the scaffold they are using has missing guard rails. What should they do?

  1. Tie themselves to the scaffold
  2. Continue but work more slowly
  3. Stop work, report the defect and do not use the scaffold until it is made safe Correct answer.
  4. Climb carefully and avoid the edge

Explanation

Incomplete or defective scaffolds must not be used. Work should stop, the defect reported and the scaffold put right and re-inspected before use.

Question 25CITB Health, safety and environment test

Under the CDM Regulations, who has the primary duty to plan, manage and monitor construction work so it is carried out without risks to health and safety?

  1. The individual roof worker
  2. The material supplier
  3. The principal contractor on notifiable projects Correct answer.
  4. The local authority

Explanation

On notifiable projects, the principal contractor has the primary duty to plan, manage and monitor construction work to ensure health and safety. This includes coordinating contractors.

Question 26CITB Health, safety and environment test

What is the main purpose of a roof edge protection system during cladding work?

  1. To stop people and materials falling from the roof edge Correct answer.
  2. To improve the weather resistance of the roof covering
  3. To provide a fixing point for the cladding rails
  4. To support the weight of the finished cladding sheets

Explanation

Edge protection is a collective fall-prevention measure placed at or near the roof edge. It prevents both persons and loose materials from falling to a lower level. It is not a structural support or a weatherproofing element.

Question 27CITB Health, safety and environment test

A roof worker is handed a harness for the first time on site. What must happen before it is used?

  1. It must be shared with a colleague to save time
  2. It must be checked and the user must be trained and competent in its use Correct answer.
  3. It must be stored in the site cabin until the next inspection
  4. It must be washed with solvent to remove dust

Explanation

Fall-arrest equipment must be inspected before use and the wearer must be trained in correct fitting and use. Using unfamiliar equipment without training is a serious risk. Solvents can damage harness webbing.

Question 28CITB Health, safety and environment test

Which type of footwear is most appropriate for working on a pitched roof?

  1. Trainers with soft rubber soles
  2. Sandals with ankle straps
  3. Wellington boots with smooth treads
  4. Safety boots with slip-resistant soles Correct answer.

Explanation

Roof work demands footwear with good grip and protective toe caps. Slip-resistant soles reduce the risk of slipping on a pitched surface. Footwear without protection or grip increases the risk of injury.

Question 29CITB Health, safety and environment test

What does a green safety sign on a construction site usually indicate?

  1. A safe condition, such as a first-aid point or escape route Correct answer.
  2. A warning of a hazard, such as a fragile roof
  3. A prohibition, such as no smoking
  4. A mandatory action, such as wearing a helmet

Explanation

Green signs denote safe conditions such as escape routes, first-aid points and safe assembly areas. Prohibition signs are red, mandatory signs are blue and warning signs are yellow. Recognising sign colours is part of basic site induction.

Question 30CITB Health, safety and environment test

What is the purpose of a method statement for a roof cladding job?

  1. To list the materials delivered to the site
  2. To record the hours each worker has spent on the roof
  3. To describe the sequence and controls for carrying out the work safely Correct answer.
  4. To confirm the client has paid for the work

Explanation

A method statement sets out how a task will be done safely, including sequence, plant, controls and responsibilities. It is a planning document, not a time sheet or commercial record. Workers should follow and understand it before starting.

Question 31CITB Health, safety and environment test

Why is it important to keep the roof work area tidy during cladding installation?

  1. To reduce trip hazards and prevent materials falling on people below Correct answer.
  2. To speed up the delivery of new sheets
  3. To avoid paying for a skip
  4. To make the finished roof look neater

Explanation

Good housekeeping removes trip hazards and stops loose items being blown or kicked off the roof. This protects both those on the roof and those below. A tidy site is a safety control, not just an aesthetic one.

Question 32CITB Health, safety and environment test

Which of these is a common early sign of heat stress in a roof worker on a hot day?

  1. Headache, dizziness and confusion Correct answer.
  2. Increased appetite and deep sleep
  3. Improved concentration and energy
  4. Cold, dry skin and shivering

Explanation

Heat stress commonly causes headache, dizziness, nausea and confusion as the body overheats. Roof work in direct sun increases the risk. Early recognition allows the worker to be cooled and rested before more serious illness develops.

Question 33CITB Health, safety and environment test

What should a worker do if they are unsure whether a roof surface can take their weight?

  1. Assume it is safe if the weather is dry
  2. Test it by stepping on it slowly
  3. Treat it as fragile and do not stand on it until it has been assessed Correct answer.
  4. Ask a colleague to walk across it first

Explanation

If there is doubt about a roof's strength, it must be treated as fragile until a competent person confirms otherwise. Testing by stepping on it risks a fall through. Weather conditions do not change the structural capacity of the roof.

Question 34CITB Health, safety and environment test

What is the main purpose of a site induction for new roof cladding workers?

  1. To assess the worker's speed of cladding installation
  2. To decide which tools the worker will buy
  3. To issue the worker's wage details
  4. To explain site-specific hazards, rules and emergency arrangements Correct answer.

Explanation

A site induction informs new workers about the particular hazards, controls, welfare and emergency procedures of that site. It is a safety briefing, not a skills test or payroll function. Attendance should be recorded.

Question 35CITB Health, safety and environment test

A worker is using a battery-powered screwdriver to fix cladding on a roof. Which control best reduces the risk of dropping the tool?

  1. Rest the tool on the roof edge between fixes
  2. Pass the tool to a colleague standing below
  3. Hold the tool in one hand while climbing
  4. Tether the tool to a secure anchor point Correct answer.

Explanation

Tethering tools prevents them from falling and striking people below. Dropped tools are a significant cause of injury on cladding projects. Resting tools near an edge or passing them between levels creates drop hazards.

Question 36CITB Health, safety and environment test

What does the term 'hierarchy of control' mean when managing roof cladding risks?

  1. Applying controls in order of effectiveness, starting with eliminating the hazard Correct answer.
  2. Ranking workers by their experience level
  3. Choosing the cheapest control available
  4. Listing controls alphabetically in the risk assessment

Explanation

The hierarchy of control ranks measures from most to least effective, starting with eliminating the hazard, then substituting, engineering controls, administrative controls and finally PPE. It guides selection of the strongest reasonably practicable control. Cost and alphabetical order are not part of the hierarchy.

Question 37CITB Health, safety and environment test

A worker on a roof notices dark clouds and hears thunder approaching. What is the correct action?

  1. Stand under the highest point of the roof for cover
  2. Continue working to finish the current sheet
  3. Carry on but put on rubber gloves
  4. Stop work, leave the roof and move to a safe shelter Correct answer.

Explanation

Roof workers are at height and may be handling metal cladding, making them vulnerable to lightning strikes. Work should stop and workers should move to a safe, enclosed shelter. Rubber gloves offer no reliable protection against lightning.

Question 38CITB Health, safety and environment test

Which of these best describes the purpose of a rescue plan for roof workers using fall-arrest equipment?

  1. To schedule the workers' lunch breaks
  2. To plan how the cladding is delivered
  3. To ensure a worker who falls is recovered quickly to avoid suspension trauma Correct answer.
  4. To decide who buys the harnesses

Explanation

A fall-arrest rescue plan ensures a fallen worker can be recovered promptly, because prolonged suspension can cause suspension trauma. It must be in place before work begins. It is not a purchasing or logistics document.

Question 39CITB Health, safety and environment test

A worker is asked to carry a long cladding sheet across an open roof in gusty conditions. What is the safest response?

  1. Grip the sheet more tightly and walk quickly
  2. Hold the sheet above head height for balance
  3. Ask a colleague to walk in front as a windbreak
  4. Stop and wait until the wind drops or use a safer handling method Correct answer.

Explanation

Long sheets act like sails and can be caught by gusts, pulling the worker off balance or off the roof. Work should pause or a safer handling method used until conditions improve. Grip strength and colleagues cannot control wind loading.

Question 40CITB Health, safety and environment test

What is the key reason for segregating a roof drop zone below a cladding operation?

  1. To keep people out of the area where falling materials could land Correct answer.
  2. To store cladding offcuts on the ground
  3. To reserve parking for the site manager
  4. To provide a walkway for site visitors

Explanation

A drop zone keeps people away from the area beneath work at height where materials could fall. It is marked and controlled so unauthorised people cannot enter. It is not a storage or parking area.

Question 41CITB Health, safety and environment test

A worker finds a crack in the casing of a power tool being used on the roof. What should they do?

  1. Wrap tape around the crack and continue
  2. Use it only for light jobs
  3. Take it out of use, label it and report it for repair Correct answer.
  4. Pass it to a colleague to finish the shift

Explanation

Damaged tool casings can expose live parts and cause electric shock, especially in damp roof conditions. The tool must be withdrawn from use, tagged and reported. Taping or passing it on leaves the hazard in place.

Question 42CITB Health, safety and environment test

Which of these is the correct way to manage the risk of manual handling when lifting cladding sheets?

  1. Twist the body while lifting to change direction
  2. Keep the load away from the body during the lift
  3. Always lift alone to save time
  4. Assess the load and use mechanical aids or team lifting where needed Correct answer.

Explanation

Manual handling risks should be assessed, and mechanical aids or team lifting used for heavy or awkward loads. Twisting while lifting and holding loads away from the body increase strain on the back. Lifting alone when a load is too heavy is unsafe.

Question 43CITB Health, safety and environment test

What should a worker do first if they witness a colleague fall from a roof and are suspended in a harness?

  1. Take a photograph for the incident report
  2. Continue working until the shift ends
  3. Wait to see if the colleague recovers on their own
  4. Raise the alarm and start the rescue plan without delay Correct answer.

Explanation

A suspended worker is at risk of suspension trauma and must be recovered quickly. The alarm should be raised and the pre-planned rescue procedure activated immediately. Delaying or photographing first wastes critical time.

Question 44CITB Health, safety and environment test

A cladding sheet is found to have a sharp, damaged edge. Why is this a safety concern during handling?

  1. It improves the grip on the sheet
  2. It reduces the wind loading on the sheet
  3. It makes the sheet lighter to carry
  4. It can cause deep cuts to hands and arms Correct answer.

Explanation

Damaged metal edges can be razor-sharp and cause serious lacerations during handling. Appropriate gloves and handling techniques should be used, and damaged sheets reported. Sharpness does not improve grip or reduce weight.

Question 45CITB Health, safety and environment test

Which of these best explains why a permit to work may be required for hot works on a roof?

  1. To confirm the worker's pay rate
  2. To record the number of sheets installed
  3. To book the site crane for the day
  4. To control ignition sources and prevent fire in the roof structure Correct answer.

Explanation

Hot works such as grinding or welding create ignition sources that can start fires in concealed roof materials. A permit controls when, where and how the work is done, including fire watch and post-work checks. It is not a timekeeping or payroll record.

Question 46CITB Health, safety and environment test

What is the main risk of using a ladder as the only means of access to a roof for cladding work?

  1. The ladder may block the site entrance
  2. The ladder may damage the cladding sheets
  3. The ladder can move or the worker can fall while carrying materials Correct answer.
  4. The ladder may be too heavy to store

Explanation

A ladder used as the sole access for prolonged work or while carrying materials is unstable and increases fall risk. Ladders are generally for short-duration, light work only, and safer access such as scaffolding should be used. Storage and site access are not the primary safety concern.

Question 47CITB Health, safety and environment test

A worker is asked to install cladding near an open roof light. What is the most appropriate control?

  1. Cover it with a loose sheet of cladding
  2. Ask the worker to step around it carefully
  3. Provide a secure cover and edge protection or guard the opening Correct answer.
  4. Mark the roof light with chalk only

Explanation

Openings such as roof lights must be securely covered or guarded so a person cannot fall through. A loose cover or chalk mark does not prevent a fall. Careful stepping is not a reliable control when working near an opening.

Question 48CITB Health, safety and environment test

Two workers disagree about whether a roof is safe to access. What is the correct course of action?

  1. Stop work and refer the decision to a competent person Correct answer.
  2. Proceed if the more experienced worker says so
  3. Proceed but work slowly
  4. Take a vote among the crew

Explanation

Where there is uncertainty about the safety of access, work should stop until a competent person has assessed the roof. Decisions about safe access must be based on assessment, not opinion or experience alone. Working slowly does not remove the hazard.

Question 49CITB Health, safety and environment test

Why is it important to plan for the sequence in which cladding sheets are fixed across a roof?

  1. To allow the crane to leave early
  2. To maintain stability and avoid creating unguarded leading edges Correct answer.
  3. To reduce the number of delivery vehicles
  4. To make the finished roof a uniform colour

Explanation

The fixing sequence affects the stability of the cladding and the position of unguarded edges as work progresses. Planning the sequence keeps workers away from unprotected leading edges and maintains structural integrity. Colour uniformity and logistics are not safety reasons.

Question 50CITB Health, safety and environment test

A worker is exposed to high noise from power tools on the roof all day. Which control is most effective under the hierarchy of control?

  1. Put up a warning sign about noise
  2. Use a quieter tool or method to reduce noise at source Correct answer.
  3. Rotate workers so each is exposed for less time
  4. Issue ear defenders and continue as before

Explanation

Under the hierarchy of control, reducing the hazard at source is more effective than relying on PPE or administrative measures. Choosing quieter tools or methods lowers the noise for everyone. Ear defenders and rotation are lower-order controls.
