SSSTS Site Supervisor Safety Training Scheme Assessment — Questions and Answers

Question 1: What does the hierarchy of control measures specify as the most effective method of controlling risk?

Providing personal protective equipment
Training workers to be more careful
Eliminating the hazard entirely (Correct answer)
Putting up warning signs

Correct answer: Eliminating the hazard entirely

The hierarchy of control, from most to least effective, is: (1) Elimination — remove the hazard entirely, (2) Substitution — replace with a less hazardous option, (3) Engineering controls — isolate people from the hazard, (4) Administrative controls — change work procedures, (5) PPE — as a last resort.

Question 2: Can a RIDDOR report be submitted on behalf of the injured worker by their supervisor?

No — RIDDOR reports can only be submitted by the company safety manager
Yes — any worker on site can submit a RIDDOR report independently
No — the RIDDOR reporting duty lies with the employer (or person in control of premises), not the individual worker or supervisor, but a supervisor may submit the report on the employer's behalf if authorised (Correct answer)
Yes — the injured worker must always submit their own RIDDOR report

Correct answer: No — the RIDDOR reporting duty lies with the employer (or person in control of premises), not the individual worker or supervisor, but a supervisor may submit the report on the employer's behalf if authorised

The duty to report under RIDDOR lies with the employer (or person in control of premises). A supervisor may be authorised by the employer to submit the report on their behalf, but the legal duty rests with the employer.

Question 3: What is the minimum frequency for reviewing site-specific induction content?

Once per year only
Whenever significant hazards change, new phases begin, or incidents occur that reveal a gap in induction content (Correct answer)
Only when the HSE requires a review
Only when a new Principal Contractor takes over

Correct answer: Whenever significant hazards change, new phases begin, or incidents occur that reveal a gap in induction content

Induction content should be reviewed whenever there is a significant change in site hazards (e.g., a new phase begins, new plant is introduced, or a serious incident reveals a gap). It should also be reviewed periodically to ensure it remains accurate and current.

Question 4: What records should a site supervisor maintain regarding safety on their section of the site?

No records are required if there are no accidents
Toolbox talk records, induction records, inspection reports, near-miss reports, accident records, and permit-to-work documentation (Correct answer)
Only the daily attendance sheet
Only accident records

Correct answer: Toolbox talk records, induction records, inspection reports, near-miss reports, accident records, and permit-to-work documentation

A site supervisor should maintain comprehensive safety records including: toolbox talk attendance and content, induction records, workplace inspection reports, near-miss and hazard reports, accident and incident records, permit-to-work documentation, and equipment inspection records.

Question 5: Who should receive a site induction under CDM 2015?

Only new employees of the principal contractor
Only management staff
Only workers who have never been on a construction site before
Every person who will work on or regularly visit the site, including subcontractors, delivery drivers, and visitors (Correct answer)

Correct answer: Every person who will work on or regularly visit the site, including subcontractors, delivery drivers, and visitors

Under CDM 2015, everyone who will work on or regularly visit the site must receive an appropriate induction. This includes all workers (regardless of employer), subcontractors, delivery drivers, visitors, client representatives, and any other person who enters the working areas of the site.

Question 6: What is the relationship between a risk assessment and a method statement?

A risk assessment replaces the need for a method statement
The risk assessment identifies the hazards and evaluates the risks, while the method statement describes how the work will be done safely, incorporating the control measures identified in the risk assessment (Correct answer)
A method statement replaces the need for a risk assessment
They are unrelated documents

Correct answer: The risk assessment identifies the hazards and evaluates the risks, while the method statement describes how the work will be done safely, incorporating the control measures identified in the risk assessment

The risk assessment and method statement are complementary documents. The risk assessment identifies what can go wrong and evaluates the level of risk. The method statement then describes the safe system of work, incorporating the control measures identified in the risk assessment into a practical, step-by-step procedure.

Question 7: What is 'likelihood' in the context of risk assessment?

The number of people exposed to a hazard
The probability or chance that a hazard will actually cause harm in the specific circumstances (Correct answer)
The severity of injury if harm occurs
The frequency with which a task is performed

Correct answer: The probability or chance that a hazard will actually cause harm in the specific circumstances

Likelihood (or probability) in risk assessment refers to how probable it is that a hazard will cause harm given the existing control measures and the specific circumstances. It is combined with severity to determine overall risk level.

Question 8: What is the legal minimum provision of rest break entitlement for adult construction workers under the Working Time Regulations 1998?

A rest break of at least 20 minutes when the working day exceeds 6 hours (Correct answer)
A 1-hour break for every 8-hour shift
No statutory rest break entitlement for construction workers
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 9: What is the hierarchy of control measures, in order from most to least effective?

Engineering controls, substitution, elimination, PPE, administrative controls
Elimination, substitution, engineering controls, administrative controls, PPE (Correct answer)
Administrative controls, PPE, engineering controls, substitution, elimination
PPE, administrative controls, engineering controls, substitution, elimination

Correct answer: Elimination, substitution, engineering controls, administrative controls, PPE

The hierarchy of controls: Elimination (remove the hazard entirely), Substitution (replace with something less hazardous), Engineering controls (physical safeguards), Administrative controls (safe systems, training), and PPE (last resort personal protection). Most effective first.

Question 10: What is a supervisor's responsibility when a worker reports they feel unwell?

Tell the worker to continue until the end of the shift
Remove the worker from the task, provide access to first aid and ensure they are assessed before returning to work (Correct answer)
Send the worker home without any assessment
Contact the worker's GP on their behalf

Correct answer: Remove the worker from the task, provide access to first aid and ensure they are assessed before returning to work

A supervisor has a duty of care for workers' wellbeing. If a worker reports illness, the supervisor must remove them from the task to prevent risk to themselves and others, arrange first-aid assessment, and ensure the worker does not return to work until confirmed fit.

Question 11: What legal definition is used for a 'young person' under health and safety legislation?

A person under 21
A person in the first year of an apprenticeship regardless of age
A person who has not yet reached 18 years of age (Correct answer)
A person under 25 in their first job

Correct answer: A person who has not yet reached 18 years of age

Under the Management of Health and Safety at Work Regulations 1999, a 'young person' is defined as anyone who has not yet reached the age of 18. A 'child' is a person below the minimum school leaving age. Different provisions apply to each category.

Question 12: What is the purpose of a 'start card' or 'last-minute risk assessment'?

The same as a formal RAMS document
A brief assessment carried out by workers immediately before starting a task to check conditions are as expected and identify any last-minute changes (Correct answer)
A record of the start time of a task
A form completed by the site manager to authorise work to begin

Correct answer: A brief assessment carried out by workers immediately before starting a task to check conditions are as expected and identify any last-minute changes

A start card or last-minute risk assessment is a brief check carried out by workers immediately before starting work to confirm that conditions match the formal risk assessment, no new hazards have arisen, the area is safe, and all equipment and PPE are available.

Question 13: What should a supervisor do if workers make negative or dismissive comments during a toolbox talk?

Address the comments respectfully, explain the genuine reasons for the safety requirement, and invite discussion rather than becoming defensive (Correct answer)
Discontinue the toolbox talk and reschedule for another time
Report the workers to HR immediately
Exclude the worker from future toolbox talks

Correct answer: Address the comments respectfully, explain the genuine reasons for the safety requirement, and invite discussion rather than becoming defensive

Negative or dismissive comments often reflect underlying concerns about practicality or past experiences. Supervisors should engage with these respectfully, explain the reasoning behind requirements, and seek the worker's alternative suggestion. This converts resistance into engagement.

Question 14: What is the primary structural purpose of scaffold ties connecting a scaffold to an adjacent building?

To transfer the dead weight of the scaffold into the building's foundations
To satisfy insurance requirements and provide a visible safety feature
To prevent the scaffold from overturning or moving away from the building under load and wind forces (Correct answer)
To allow the scaffold to bear additional loads transferred from the building structure

Correct answer: To prevent the scaffold from overturning or moving away from the building under load and wind forces

Scaffold ties resist both inward and outward forces — they prevent the scaffold from overturning (falling outward) or moving inward against the building face, maintaining stability under wind loads and working loads.

Question 15: What is a dynamic risk assessment, and when might a site supervisor need to carry one out?

A risk assessment that is updated annually
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 completed after an accident
A risk assessment for moving vehicles only

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 16: What key information should a method statement include?

A drawing of the finished product
Only the start and finish dates
The scope of work, sequence of operations, hazards and risks, control measures, PPE requirements, emergency procedures, and the competencies needed (Correct answer)
Only the name of the contractor

Correct answer: The scope of work, sequence of operations, hazards and risks, control measures, PPE requirements, emergency procedures, and the competencies needed

A comprehensive method statement includes: description and scope of the work, step-by-step sequence of operations, hazards and risks at each stage, control measures for each hazard, PPE requirements, plant and equipment needed, competency requirements, emergency procedures, and environmental considerations.

Question 17: What immediate action should a site supervisor take following a reportable injury on site?

Clean up the area before informing management
Provide first aid, call emergency services if needed, secure the scene, complete accident records and notify management to report to the HSE (Correct answer)
Carry on working to minimise disruption
Only notify the HSE and not management

Correct answer: Provide first aid, call emergency services if needed, secure the scene, complete accident records and notify management to report to the HSE

Following a reportable injury: provide and facilitate immediate first aid, call emergency services if required, preserve the scene (do not disturb anything unnecessarily), make a detailed record of the incident, notify management, and ensure the RIDDOR report is made to the HSE within the required timeframe.

Question 18: How should a method statement address environmental controls on a construction site?

Only mention environmental controls if the site is in a national park
Environmental controls are not relevant to method statements
Include measures to control dust, noise, vibration, waste disposal, protection of watercourses, and any ecological protections required (Correct answer)
Environmental controls are only the responsibility of the Environment Agency

Correct answer: Include measures to control dust, noise, vibration, waste disposal, protection of watercourses, and any ecological protections required

Method statements should address environmental impacts including dust suppression measures, noise and vibration controls (especially near residential areas), waste management and disposal procedures, protection of watercourses from pollution, ecological protections (protected species, trees), and compliance with environmental permits.

Question 19: What is the primary health and safety responsibility of a site supervisor under CDM 2015?

Appointing the Principal Designer
Ensuring workers under their supervision follow the Construction Phase Plan and safe systems of work (Correct answer)
Notifying HSE of the project commencement
Designing the health and safety file

Correct answer: Ensuring workers under their supervision follow the Construction Phase Plan and safe systems of work

A site supervisor's primary responsibility is to ensure that workers under their control follow the arrangements set out in the Construction Phase Plan and the safe systems of work established for each activity.

Question 20: What is the HSE's RIDDOR online reporting portal known as?

Companies House filing portal
The RIDDOR online portal at riddor.hse.gov.uk (Correct answer)
CITB training portal
HMRC gateway

Correct answer: The RIDDOR online portal at riddor.hse.gov.uk

RIDDOR reports are submitted via the HSE's dedicated online reporting system at riddor.hse.gov.uk. This portal guides reporters through the relevant form for the type of incident and provides immediate confirmation of submission.

Question 21: Under Regulation 4 of the Work at Height Regulations 2005, what are the three core duties an employer must fulfil before work at height commences?

Complete a RIDDOR report, brief the emergency services, and install safety nets
Purchase appropriate equipment, train all workers, and display warning signs
Ensure all work at height is properly planned, appropriately supervised and carried out safely by competent persons (Correct answer)
Notify the HSE, obtain a permit to work, and brief the workforce

Correct answer: Ensure all work at height is properly planned, appropriately supervised and carried out safely by competent persons

Regulation 4 requires that every employer ensures work at height is properly planned (including emergencies), appropriately supervised, and carried out in a manner that is so far as is reasonably practicable safe, using competent persons.

Question 22: What is the supervisor's role in monitoring and controlling working hours to prevent fatigue-related accidents?

Only night shift workers need rest breaks
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)
Workers should manage their own rest breaks
Working hours are irrelevant to safety

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 23: How can a site supervisor make toolbox talks more engaging and interactive?

Use real examples from site, encourage questions and discussion, show relevant photos or equipment, and ask workers to share their experiences (Correct answer)
Deliver the talk in under 2 minutes to minimise disruption
Only deliver talks to workers who volunteer to attend
Read from a printed sheet without making eye contact

Correct answer: Use real examples from site, encourage questions and discussion, show relevant photos or equipment, and ask workers to share their experiences

Effective delivery involves: using real-life examples and site-specific scenarios, encouraging questions and two-way discussion, using props (showing actual equipment or PPE), asking workers about their experiences, keeping the tone conversational rather than lecturing, and using visual aids where appropriate.

Question 24: What is the purpose of a construction phase plan under CDM 2015?

To list all subcontractors and their costs
To satisfy planning permission requirements
To set out the project programme and milestones
To set out the health and safety arrangements, site rules, and specific measures for managing high-risk activities during the construction phase (Correct answer)

Correct answer: To set out the health and safety arrangements, site rules, and specific measures for managing high-risk activities during the construction phase

The construction phase plan (required under Regulation 12) sets out the arrangements for managing health and safety during construction. It includes site rules, arrangements for controlling significant risks, emergency procedures, and management of specific high-risk activities such as work at height or with asbestos.

Question 25: A foreign worker with limited English arrives for their site induction. How should the supervisor handle this?

Skip the induction and let them follow other workers
Give them the standard English induction and assume they understand
Provide the induction in a language the worker understands, using translated materials, an interpreter, or visual aids, and verify their understanding before allowing them to work (Correct answer)
Refuse to allow them on site

Correct answer: Provide the induction in a language the worker understands, using translated materials, an interpreter, or visual aids, and verify their understanding before allowing them to work

The supervisor must ensure the worker genuinely understands the safety information. This may require translated induction materials, the use of an interpreter, visual aids and diagrams, demonstration of procedures, and verification of understanding through questions — not just a signature on the register.

Question 26: What is a 'task-specific' risk assessment?

A generic assessment covering common activities across an industry
An assessment for an entire project rather than individual tasks
An assessment prepared for a specific activity to be carried out at a specific location, addressing the actual hazards of that exact task (Correct answer)
An assessment for a category of tasks such as 'all lifting operations'

Correct answer: An assessment prepared for a specific activity to be carried out at a specific location, addressing the actual hazards of that exact task

A task-specific risk assessment is prepared for a particular activity at a specific location, addressing the actual hazards of that exact task in its real context. It is more focused and relevant than a generic assessment and should reflect the specific site conditions.

Question 27: What document should a site supervisor check before allowing a subcontractor's workers onto site?

Only the subcontractor's invoice
The subcontractor's company logo and branding
The subcontractor's competence records, including CSCS cards, relevant training certificates, and insurance documentation (Correct answer)
The subcontractor's social media presence

Correct answer: The subcontractor's competence records, including CSCS cards, relevant training certificates, and insurance documentation

Before allowing subcontractor workers onto site, the supervisor should verify their competence through CSCS (Construction Skills Certification Scheme) cards, relevant training and qualification certificates, and confirm the subcontractor has adequate insurance (employer's liability and public liability).

Question 28: A site supervisor notices a worker not wearing their hard hat in a designated area. What should the supervisor do first?

Stop the worker, explain the risk, ensure they put on their hard hat, and record the intervention (Correct answer)
Send the worker home immediately without discussion
Ignore it as it is the worker's personal choice
Wait until the end of the shift to discuss it

Correct answer: Stop the worker, explain the risk, ensure they put on their hard hat, and record the intervention

The supervisor should immediately intervene to address the PPE non-compliance. This involves stopping the unsafe behaviour, explaining why the hard hat is required (risk of head injury from falling objects), ensuring compliance, and recording the intervention for safety management purposes.
