SSSTS Site Supervisor Safety Training Scheme Assessment — Questions and Answers

Question 1: What is a dynamic risk assessment, and when might a site supervisor need to carry one out?

A continuous, real-time assessment of changing conditions, used when site conditions change unexpectedly and the formal written assessment no longer covers the situation (Correct answer)
A risk assessment for moving vehicles only
A risk assessment that is updated annually
A risk assessment completed after an accident

Correct answer: A continuous, real-time assessment of changing conditions, used when site conditions change unexpectedly and the formal written assessment no longer covers the situation

A dynamic risk assessment is an ongoing, real-time process of identifying and assessing risks as conditions change on site. Supervisors use it when unexpected hazards arise, conditions change (e.g., weather), or when the planned work differs from what was anticipated in the formal risk assessment.

Question 2: Who should be consulted when carrying out a risk assessment on a construction site?

Only the health and safety officer
Workers who carry out the tasks, safety representatives, competent persons, and any specialists relevant to the hazards identified (Correct answer)
No consultation is required
Only the project manager

Correct answer: Workers who carry out the tasks, safety representatives, competent persons, and any specialists relevant to the hazards identified

Effective risk assessment requires consultation with those who do the work (they understand the practical risks), safety representatives, competent health and safety advisers, and relevant specialists (e.g., structural engineers, occupational hygienists) depending on the hazards involved.

Question 3: What is a 'dynamic risk assessment' in the context of a site supervisor's role?

A computerised risk assessment tool
A risk assessment updated once per week
A risk assessment carried out by the site safety officer each morning
The ongoing assessment of changing conditions during the working day, adapting control measures when unexpected hazards arise (Correct answer)

Correct answer: The ongoing assessment of changing conditions during the working day, adapting control measures when unexpected hazards arise

Site supervisors must continuously and dynamically assess conditions throughout the day. When conditions change unexpectedly (ground conditions, weather, adjacent activities), they must adapt control measures immediately and, if necessary, stop work and revise the formal risk assessment.

Question 4: What is the legal minimum provision of rest break entitlement for adult construction workers under the Working Time Regulations 1998?

No statutory rest break entitlement for construction workers
A 1-hour break for every 8-hour shift
A rest break of at least 20 minutes when the working day exceeds 6 hours (Correct answer)
30 minutes every 4 hours regardless of shift length

Correct answer: A rest break of at least 20 minutes when the working day exceeds 6 hours

Under the Working Time Regulations 1998, workers are entitled to a rest break of at least 20 minutes when they work for more than 6 hours in a day. This is an uninterrupted break away from the work station. Young workers have enhanced entitlements.

Question 5: What visual aids are most effective in a toolbox talk?

Dense text-heavy slides projected onto a screen
Complex engineering drawings
Photographs of the actual work area or similar accidents, physical examples of defective PPE or equipment, and simple diagrams (Correct answer)
The full text of the relevant legislation

Correct answer: Photographs of the actual work area or similar accidents, physical examples of defective PPE or equipment, and simple diagrams

Visual aids such as photographs of actual site conditions, examples of the consequences of poor practice (accident photos from similar incidents), physical PPE examples and simple diagrams are far more engaging and memorable than text-heavy presentations.

Question 6: What should a method statement specify regarding the inspection and maintenance of equipment used for the task?

Equipment inspection is not part of the method statement
The pre-use inspection requirements, maintenance schedule, competent persons who can inspect, and actions to take if equipment is found to be defective (Correct answer)
Equipment should be inspected annually regardless of use
Only new equipment needs inspection

Correct answer: The pre-use inspection requirements, maintenance schedule, competent persons who can inspect, and actions to take if equipment is found to be defective

The method statement should specify what pre-use checks are required (daily inspections), the formal inspection schedule (e.g., weekly for scaffolding under the Work at Height Regulations), who is competent to carry out inspections, required documentation, and the procedure for taking defective equipment out of service.

Question 7: What information should a site induction specifically cover for new workers who are unfamiliar with construction sites?

The procurement process for materials
The payment and expense process
Only the site's commercial programme
The types of plant and vehicles they may encounter, no-go areas, overhead hazard zones, excavation exclusion zones, and how to respond if they see an unsafe act (Correct answer)

Correct answer: The types of plant and vehicles they may encounter, no-go areas, overhead hazard zones, excavation exclusion zones, and how to respond if they see an unsafe act

New workers unfamiliar with construction sites must understand the site's vehicle and plant movements, zones where they must not go, overhead hazards (cranes, working at height activities), excavation risks, and how to raise safety concerns. These are the hazards most likely to harm inexperienced persons.

Question 8: When should a risk assessment be reviewed?

When there is reason to believe it is no longer valid (e.g., changes in conditions, after an accident) and at suitable intervals (Correct answer)
Only when requested by the HSE
Only after a fatal accident
At the start of the project and never again

Correct answer: When there is reason to believe it is no longer valid (e.g., changes in conditions, after an accident) and at suitable intervals

Risk assessments must be kept up to date. Reviews are required when there is reason to believe the assessment is no longer valid — for example, when working methods change, new hazards arise, after an accident, or when there are significant changes in the workforce.

Question 9: A worker approaches the supervisor to report that they feel unsafe performing a particular task. How should the supervisor respond?

Ignore the complaint as workers often exaggerate
Listen to the worker's concerns, assess whether the task is genuinely unsafe, take appropriate action to address any risks, and thank the worker for raising the concern (Correct answer)
Tell the worker to get on with it or go home
Tell the worker to put it in writing and submit it to HR

Correct answer: Listen to the worker's concerns, assess whether the task is genuinely unsafe, take appropriate action to address any risks, and thank the worker for raising the concern

A supervisor should take all safety concerns seriously. They should listen actively, investigate whether the concern is valid, take immediate action if there is a genuine risk, and positively reinforce the reporting behaviour to maintain a culture where workers feel comfortable raising safety issues.

Question 10: A worker arrives on site with an expired CSCS card. What should the supervisor do during the induction process?

Ask them to apply for a new card while they work
Allow them to work in low-risk areas only
Allow them to start work as the card is just a formality
Refuse site access until a valid CSCS card is presented, as it demonstrates the worker's competence and health and safety awareness (Correct answer)

Correct answer: Refuse site access until a valid CSCS card is presented, as it demonstrates the worker's competence and health and safety awareness

The CSCS card demonstrates that the holder has the appropriate training, qualifications, and health and safety awareness for their role. An expired card means these may not be current. The supervisor should refuse access and advise the worker to renew their card before returning to site.

Question 11: What does a site supervisor need to confirm before a new contractor starts work in their area?

That the contractor has received site induction, holds relevant qualifications, has read the relevant method statement and has appropriate equipment (Correct answer)
That the contractor has paid their trade union subscription
That the contractor is registered with the HSE
That the contractor has agreed to work at reduced rates

Correct answer: That the contractor has received site induction, holds relevant qualifications, has read the relevant method statement and has appropriate equipment

Before a new contractor starts work, the supervisor must confirm they have been inducted to the site, are competent for the tasks to be performed, have read and understood the relevant method statement, and have the right tools, equipment and PPE.

Question 12: Under CDM 2015, what must a designer do to comply with their duties?

Designers must eliminate foreseeable risks where possible, reduce risks that cannot be eliminated, and provide information about any remaining risks to those who need it (Correct answer)
Designers must carry out all risk assessments for the contractor
Designers only need to produce aesthetically pleasing buildings
Designers have no health and safety duties

Correct answer: Designers must eliminate foreseeable risks where possible, reduce risks that cannot be eliminated, and provide information about any remaining risks to those who need it

Under CDM 2015 Regulation 9, designers must eliminate foreseeable risks so far as reasonably practicable through design choices, reduce risks that cannot be eliminated through design, and provide information about remaining significant risks to contractors and others who need it for safe construction and maintenance.

Question 13: Which of the following is a RIDDOR 'specified injury' that must be reported?

A cut requiring three stitches
A strained back requiring two days off work
Bruising to the arm from a fall
A fracture of any bone other than a finger, thumb or toe (Correct answer)

Correct answer: A fracture of any bone other than a finger, thumb or toe

Specified injuries under RIDDOR 2013 include: fractures other than to fingers, thumbs or toes; amputations; permanent loss of sight or reduction of sight; crush injuries to head or torso; burns covering more than 10% of the body; and scalping injuries.

Question 14: What is the main purpose of a site induction?

To give every person the specific health and safety information they need to be safe on that particular site before they start work (Correct answer)
To provide payroll and HR information
To assess the competence of new workers
To introduce workers to their line managers

Correct answer: To give every person the specific health and safety information they need to be safe on that particular site before they start work

The site induction provides site-specific health and safety information: emergency procedures, site rules, significant hazards and their controls, welfare facilities, PPE requirements and reporting lines. It is the foundation for safe working on that particular project.

Question 15: How often should toolbox talks be delivered on a construction site?

Only at the start of the project
Only when the HSE visits the site
Regularly throughout the project, typically weekly or when new hazards arise, when working methods change or following an incident (Correct answer)
Only following a RIDDOR-reportable accident

Correct answer: Regularly throughout the project, typically weekly or when new hazards arise, when working methods change or following an incident

Best practice is to deliver toolbox talks regularly (often weekly), and additionally whenever new hazards arise, working methods change, new plant or materials are introduced, or following a near miss or accident. Regular delivery reinforces the safety culture.

Question 16: How should a site induction be documented?

Only the worker's name needs to be recorded
A signed register should record each worker's name, employer, CSCS card number, date of induction, and confirmation they understood the content (Correct answer)
A verbal confirmation from the supervisor is sufficient
Documentation is not necessary

Correct answer: A signed register should record each worker's name, employer, CSCS card number, date of induction, and confirmation they understood the content

Site induction records should include: the worker's full name, their employer/company, CSCS card details, date of induction, the topics covered, and the worker's signature confirming attendance and understanding. These records provide evidence of compliance and may be needed during HSE investigations.

Question 17: A site supervisor discovers that a piece of plant equipment has a defective safety guard. What action should they take?

Report it at the next weekly meeting
Allow work to continue if the operator is experienced
Immediately take the equipment out of use, tag it as defective, and arrange for repair or replacement before it is used again (Correct answer)
Ask the operator to be extra careful

Correct answer: Immediately take the equipment out of use, tag it as defective, and arrange for repair or replacement before it is used again

Defective safety guards present an immediate risk of serious injury. The supervisor must take the equipment out of service immediately, clearly tag or mark it as defective to prevent use, and arrange for competent repair or replacement. Work with the equipment must not resume until the guard is properly functioning.

Question 18: A method statement specifies that a particular task requires a banksman. What is the role of a banksman?

A person who inspects scaffolding
A person who manages the project finances
A person who operates the crane
A trained person who guides vehicle and plant movements using agreed hand signals or radio communication to ensure safe operations (Correct answer)

Correct answer: A trained person who guides vehicle and plant movements using agreed hand signals or radio communication to ensure safe operations

A banksman (also called a signaller) is a trained person who directs the movement of vehicles, cranes, or plant on site using standardised hand signals or radio communication. They ensure safe movement in areas where the operator's visibility is restricted or where pedestrians may be at risk.

Question 19: What is a Method Statement and how does it relate to a risk assessment?

A Method Statement is only required for high-rise construction
A Method Statement sets out the sequence of work and the safe system of work; together with the risk assessment it forms a RAMS document (Correct answer)
A Method Statement replaces the risk assessment for low-risk activities
A Method Statement is the same document as a risk assessment

Correct answer: A Method Statement sets out the sequence of work and the safe system of work; together with the risk assessment it forms a RAMS document

A Method Statement describes how a specific task will be carried out safely, step by step, including the sequence of operations and the control measures. Combined with the risk assessment, it forms a RAMS (Risk Assessment and Method Statement) document that guides safe working.

Question 20: What is the purpose of a method statement on a construction site?

To list the materials needed for a task
To record completed work for billing purposes
To describe the safe system of work for a specific activity, detailing the sequence of operations, hazards, and control measures step by step (Correct answer)
To set out the programme of works

Correct answer: To describe the safe system of work for a specific activity, detailing the sequence of operations, hazards, and control measures step by step

A method statement (also called a safe system of work) describes how a specific task or activity will be carried out safely. It details the sequence of operations, identifies hazards at each stage, specifies control measures, and outlines the resources, equipment, and competencies required.

Question 21: How should a supervisor handle a worker who raises a concern or question during a toolbox talk?

Take the concern seriously, address it at the time or undertake to investigate and report back, and record the issue (Correct answer)
Dismiss the concern if it relates to a job the worker is not assigned to
Tell the worker to raise the matter with the safety officer instead
Postpone the toolbox talk and reschedule it for another day

Correct answer: Take the concern seriously, address it at the time or undertake to investigate and report back, and record the issue

Questions and concerns during toolbox talks should be welcomed and taken seriously. If the answer is not immediately available, the supervisor should undertake to investigate and report back promptly. This reinforces a positive safety culture.

Question 22: What is the supervisor's responsibility regarding the welfare facilities on a construction site under the Construction (Design and Management) Regulations 2015?

The supervisor should ensure that adequate welfare facilities (toilets, washing facilities, drinking water, rest areas) are available and maintained (Correct answer)
Welfare facilities are not the supervisor's concern
Welfare facilities are only required on sites lasting more than 6 months
Only the client is responsible for welfare facilities

Correct answer: The supervisor should ensure that adequate welfare facilities (toilets, washing facilities, drinking water, rest areas) are available and maintained

Under CDM 2015, Schedule 2, adequate welfare facilities must be provided on all construction sites. The supervisor should ensure these include sanitary conveniences, washing facilities, drinking water, rest facilities, and changing rooms where needed, and that they are kept clean and maintained.

Question 23: What is a 'near miss' register and how should a site supervisor use it?

A record kept only by the HSE
A document only reviewed after a serious accident occurs
A register recording all near-miss events, used by the supervisor to identify hazard trends, prioritise corrective action and demonstrate proactive safety management (Correct answer)
A list of workers who nearly had accidents

Correct answer: A register recording all near-miss events, used by the supervisor to identify hazard trends, prioritise corrective action and demonstrate proactive safety management

A near-miss register records all near-miss events on a site. Supervisors should review it regularly to identify patterns (e.g., repeated near misses at the same location or involving the same activity) and take targeted preventive action before a serious accident occurs.

Question 24: What is the supervisor's role in monitoring and controlling working hours to prevent fatigue-related accidents?

Workers should manage their own rest breaks
Working hours are irrelevant to safety
The supervisor should monitor working hours, ensure adequate rest breaks are taken, and intervene if workers show signs of fatigue that could compromise safety (Correct answer)
Only night shift workers need rest breaks

Correct answer: The supervisor should monitor working hours, ensure adequate rest breaks are taken, and intervene if workers show signs of fatigue that could compromise safety

Fatigue is a significant cause of construction accidents. The supervisor should monitor working hours, ensure compliance with the Working Time Regulations 1998, enforce rest breaks, and watch for signs of fatigue such as reduced concentration, poor decision-making, or impaired coordination.

Question 25: A worker reports that their fall arrest harness causes discomfort and chafing during use. What action should the site supervisor take?

Issue the worker with a written instruction to use the PPE and record their refusal
Advise the worker that all harnesses cause some discomfort and insist they continue using it
Allow the worker to work without a harness provided they work carefully near the platform edge
Ensure the harness is correctly adjusted for the individual and consider whether a different size or harness type is needed (Correct answer)

Correct answer: Ensure the harness is correctly adjusted for the individual and consider whether a different size or harness type is needed

The supervisor must ensure PPE provided is suitable for the individual; an ill-fitting harness may not perform correctly in a fall and workers are more likely to use PPE that fits comfortably, so correct adjustment and an alternative fit should be considered.

Question 26: How long is an SSSTS certificate valid before renewal is required?

5 years (Correct answer)
10 years
3 years
2 years

Correct answer: 5 years

An SSSTS certificate is valid for 5 years. After this period, supervisors must complete a 1-day SSSTS Renewal course to maintain their qualification. This ensures supervisors keep their health and safety knowledge up to date.

Question 27: What is the purpose of keeping an accident book on a construction site?

To record all injuries at work, including those below the RIDDOR threshold, so there is a comprehensive record for management review and legal protection (Correct answer)
Only to provide information for insurance claims
To satisfy RIDDOR by acting as a RIDDOR report
Only to record RIDDOR-reportable injuries

Correct answer: To record all injuries at work, including those below the RIDDOR threshold, so there is a comprehensive record for management review and legal protection

An accident book records all injuries that occur at work, including minor injuries below the RIDDOR threshold. This creates a comprehensive record for identifying trends, managing occupational health, and providing evidence if an injury later proves more serious or legal action follows.

Question 28: Under the Work at Height Regulations 2005, which statement best describes the legal definition of 'work at height'?

Any work performed on a ladder, scaffold or elevated platform
Work in any place where a person could fall and be injured, including at or below ground level (Correct answer)
Any work carried out more than 2 metres above the ground
Work conducted only on rooftops or permanent elevated structures

Correct answer: Work in any place where a person could fall and be injured, including at or below ground level

The Work at Height Regulations 2005 define work at height as any location where a person could fall and sustain injury, which includes ground level (e.g., near an excavation) as well as elevated positions.
