SSSTS Site Supervisor Safety Training Scheme Assessment — Questions and Answers

Question 1: What is a site supervisor's responsibility regarding the provision of welfare facilities?

Welfare facilities are the client's responsibility under CDM 2015
To only check welfare facilities during formal inspections
To ensure welfare facilities (toilets, washing facilities, rest area, drinking water) are available, clean and maintained throughout the shift (Correct answer)
To build the welfare facilities themselves

Correct answer: To ensure welfare facilities (toilets, washing facilities, rest area, drinking water) are available, clean and maintained throughout the shift

Supervisors must ensure welfare facilities are available, maintained in a clean and serviceable condition, and accessible to all workers at all times. Under CDM 2015, the Principal Contractor is responsible for providing welfare — supervisors maintain and monitor this.

Question 2: What role does the CSCS card play in the site induction process?

It is a loyalty card for construction workers
It is only needed for scaffold workers
It is only required on sites worth over £1 million
It verifies that the worker has achieved the required level of health and safety awareness and holds relevant qualifications for their trade, forming part of the competence check during induction (Correct answer)

Correct answer: It verifies that the worker has achieved the required level of health and safety awareness and holds relevant qualifications for their trade, forming part of the competence check during induction

The CSCS card is checked during induction as evidence of competence. It confirms that the holder has passed the appropriate health and safety test (CITB Health, Safety and Environment Test) and holds relevant qualifications for their occupation. Different card colours indicate different levels of qualification.

Question 3: What is the purpose of a method statement on a construction site?

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 list the materials needed for a task
To record completed work for billing purposes
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 4: When delegating tasks to workers, what must a site supervisor ensure?

That the task is completed as quickly as possible regardless of safety
That only the most senior worker is given tasks
That the worker is competent, has received adequate briefing, understands the risks, has the correct tools and PPE, and knows the safe system of work (Correct answer)
That the worker has signed a waiver of liability

Correct answer: That the worker is competent, has received adequate briefing, understands the risks, has the correct tools and PPE, and knows the safe system of work

Effective delegation requires the supervisor to verify the worker's competence for the specific task, provide adequate briefing on the method and risks, ensure correct tools and PPE are available, confirm the worker understands the safe system of work, and monitor progress.

Question 5: How often should risk assessments for high-risk activities be reviewed on a construction project?

Only after a serious accident
Regularly throughout the project and whenever conditions, methods or personnel change significantly (Correct answer)
Only at the start of the project
Once per year

Correct answer: Regularly throughout the project and whenever conditions, methods or personnel change significantly

High-risk activity risk assessments should be reviewed regularly (e.g., at the start of each phase) and whenever there are significant changes to working methods, site conditions, personnel, equipment or when an incident occurs that suggests the assessment may be inadequate.

Question 6: What is the difference between a site induction and a task-specific briefing?

A site induction covers general site safety for all workers, while a task-specific briefing covers the particular hazards and safe methods for a specific activity (Correct answer)
A task-specific briefing replaces the need for a site induction
They are the same thing
A site induction is only for management while task briefings are for workers

Correct answer: A site induction covers general site safety for all workers, while a task-specific briefing covers the particular hazards and safe methods for a specific activity

A site induction provides general information applicable to everyone on site (site rules, emergency procedures, welfare). A task-specific briefing provides detailed information about a particular activity (risk assessment, method statement, specific hazards, required controls) and is given to those carrying out that specific task.

Question 7: What is a 'behavioural safety programme' and how does it relate to induction and supervision of young workers?

A programme only relevant to senior managers
A programme that replaces the need for formal risk assessments
A structured approach to understanding and positively influencing safety behaviours; for young workers, induction and ongoing supervision are key components in establishing safe behavioural norms from the start (Correct answer)
A disciplinary programme for workers who repeatedly break safety rules

Correct answer: A structured approach to understanding and positively influencing safety behaviours; for young workers, induction and ongoing supervision are key components in establishing safe behavioural norms from the start

Behavioural safety programmes recognise that accidents often result from unsafe behaviours and aim to understand and change them positively. For young workers, establishing safe behaviours from day one through thorough induction and consistent, constructive supervision is a foundational element.

Question 8: What is a 'dangerous occurrence' involving a crane on a construction site that must be reported under RIDDOR?

The collapse, overturning or failure of any load-bearing part of a crane (Correct answer)
Any unplanned movement of a crane
A crane operating at the limits of its radius
Any repair work carried out on a crane

Correct answer: The collapse, overturning or failure of any load-bearing part of a crane

Under RIDDOR 2013 Schedule 2, the collapse, overturning or failure of a load-bearing part of a crane (or other lifting equipment) is a dangerous occurrence that must be reported to the HSE, even if no injury results.

Question 9: What is the purpose of RIDDOR reporting from a construction site supervisor's perspective?

To provide the HSE with data to identify trends, investigate serious incidents and target enforcement, and to create a record for the site to investigate causes (Correct answer)
Only for insurance purposes
Only relevant if the HSE decides to prosecute
Only to satisfy a legal obligation with no practical benefit

Correct answer: To provide the HSE with data to identify trends, investigate serious incidents and target enforcement, and to create a record for the site to investigate causes

RIDDOR reporting provides the HSE with data to identify industry accident trends and target resources. From the site perspective, reports trigger internal investigation that should lead to improved control measures to prevent recurrence.

Question 10: What is the 'accident triangle' (Heinrich's triangle) and how does it relate to RIDDOR reporting?

The three parties responsible for accident reporting under RIDDOR
It is the triangular PPE sign used to indicate accident risk areas
For every major injury, there are many minor injuries and a much larger number of near misses; RIDDOR focuses on the top of the triangle but near-miss investigation addresses the base (Correct answer)
A legal framework for ranking accidents by severity

Correct answer: For every major injury, there are many minor injuries and a much larger number of near misses; RIDDOR focuses on the top of the triangle but near-miss investigation addresses the base

Heinrich's (or Bird's) accident triangle describes the relationship between serious accidents, minor accidents and near misses. RIDDOR captures the most serious events, but investigating near misses (the bottom of the triangle) prevents the serious incidents at the top.

Question 11: Under the Work at Height Regulations 2005, which of the following activities does NOT constitute 'work at height'?

A worker installing a light fitting while standing on a step ladder inside a building
A worker in a basement drilling near an unguarded floor opening at ground level
A worker sitting at a desk on the third floor of an office building (Correct answer)
A worker on a flat roof carrying out a survey inspection

Correct answer: A worker sitting at a desk on the third floor of an office building

A worker seated at an interior desk on an upper floor is not 'working at height' under the regulations because there is no reasonably foreseeable risk of them falling — the risk of falling is the defining factor, not simply being in an elevated location.

Question 12: When should a method statement be revised?

Only when the client requests changes
When site conditions change, the work method is altered, new hazards are identified, after an incident, or when a review identifies improvements (Correct answer)
Never — once written it is final
Only at the end of the project for lessons learned

Correct answer: When site conditions change, the work method is altered, new hazards are identified, after an incident, or when a review identifies improvements

Method statements should be revised when there are changes to site conditions, work methods, equipment, or personnel; when new hazards are identified; after an accident or near miss relating to the activity; or when a review identifies that improvements can be made to the safe system of work.

Question 13: 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
Ensure the harness is correctly adjusted for the individual and consider whether a different size or harness type is needed (Correct answer)
Allow the worker to work without a harness provided they work carefully near the platform edge

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 14: The Work at Height Regulations 2005 require that arrangements are in place for the prompt rescue of a person who has fallen and is suspended in a fall arrest harness. Why is prompt rescue particularly critical?

Because the fall arrest lanyard may release if tension is maintained for too long
Because suspension trauma (harness-induced pathology) can cause blood to pool in the legs, leading to unconsciousness and death within minutes (Correct answer)
Because the harness webbing degrades rapidly under body weight and may fail after 10 minutes
Because RIDDOR requires a rescue to be completed within 15 minutes of a fall event

Correct answer: Because suspension trauma (harness-induced pathology) can cause blood to pool in the legs, leading to unconsciousness and death within minutes

Suspension trauma occurs when a motionless person is suspended in an upright harness — blood pools in the legs reducing circulation to vital organs, which can cause unconsciousness and be fatal within minutes, making a pre-planned rescue essential.

Question 15: A site supervisor discovers that a piece of plant equipment has a defective safety guard. What action should they take?

Allow work to continue if the operator is experienced
Report it at the next weekly meeting
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 16: What happens if a project starts with one contractor and then a second contractor is appointed?

The first contractor automatically becomes the principal contractor
The client must appoint a principal contractor and principal designer as the project now involves more than one contractor (Correct answer)
Nothing changes — CDM duties remain the same
CDM 2015 does not apply to such situations

Correct answer: The client must appoint a principal contractor and principal designer as the project now involves more than one contractor

When a project involves more than one contractor, CDM 2015 requires the client to appoint a principal designer and a principal contractor. If a single-contractor project becomes a multi-contractor project, these appointments must be made promptly to ensure proper coordination of health and safety.

Question 17: Under the Management of Health and Safety at Work Regulations 1999, what must a supervisor do if they identify a serious and imminent danger?

Implement the emergency procedure, evacuate workers from the danger area, and prevent workers from re-entering until the danger is resolved (Correct answer)
Call a meeting to discuss options
Only the health and safety manager can respond to serious dangers
Continue work but note it in the diary

Correct answer: Implement the emergency procedure, evacuate workers from the danger area, and prevent workers from re-entering until the danger is resolved

Under Regulation 8 of the Management of Health and Safety at Work Regulations 1999, when a serious and imminent danger is identified, workers must be informed, the area must be evacuated, and workers must not be allowed to return until the danger has been eliminated or adequately controlled.

Question 18: A client representative is visiting the site and asks to see evidence that toolbox talks have been delivered. What documentation should the supervisor provide?

A verbal assurance that talks are delivered
The supervisor's personal diary
The toolbox talk register showing dates, topics, attendance records with signatures, and any follow-up actions from questions raised (Correct answer)
The company's safety policy document

Correct answer: The toolbox talk register showing dates, topics, attendance records with signatures, and any follow-up actions from questions raised

The toolbox talk register provides formal evidence of compliance. It should include: dates and times of talks, topics covered (ideally with copies of the talk content), signed attendance records, any questions raised by workers, and actions taken in response. This demonstrates a systematic approach to safety communication.

Question 19: What is the hierarchy of control measures, in order from most to least effective?

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

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 20: What is the five-step process for risk assessment?

Identify hazards; identify who might be harmed and how; evaluate the risk and existing controls; record findings; review and update (Correct answer)
Measure exposure, compare with WEL, record, control, review
Spot the hazard, fix it, document it, sign it off, file it
Eliminate all hazards before work starts

Correct answer: Identify hazards; identify who might be harmed and how; evaluate the risk and existing controls; record findings; review and update

The HSE's five-step approach to risk assessment: (1) identify hazards, (2) decide who might be harmed and how, (3) evaluate risks and existing controls, (4) record significant findings, (5) review the assessment and update when necessary.

Question 21: What records should a site supervisor maintain regarding safety on their section of the site?

Toolbox talk records, induction records, inspection reports, near-miss reports, accident records, and permit-to-work documentation (Correct answer)
Only the daily attendance sheet
No records are required if there are no accidents
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 22: What health and safety information should a supervisor provide during a site induction?

Only the location of the canteen
Health and safety legislation in full detail
Emergency procedures, site rules, significant hazards and controls, welfare facilities, PPE requirements and reporting procedures (Correct answer)
Commercial programme and project value

Correct answer: Emergency procedures, site rules, significant hazards and controls, welfare facilities, PPE requirements and reporting procedures

Induction content must cover: emergency procedures (fire, first aid, evacuation), site rules, significant hazards identified in the CPP, control measures, welfare facilities, PPE requirements, accident/near-miss reporting, and key contacts.

Question 23: What is the supervisor's role in 'safety conversations' as opposed to formal toolbox talks?

Safety conversations are only appropriate after an accident
Safety conversations replace toolbox talks and RAMS
Safety conversations are only for senior management
Having informal one-to-one conversations with workers about safety, asking about hazards they encounter, demonstrating that safety is a constant priority rather than a box-ticking exercise (Correct answer)

Correct answer: Having informal one-to-one conversations with workers about safety, asking about hazards they encounter, demonstrating that safety is a constant priority rather than a box-ticking exercise

Safety conversations are informal, one-to-one dialogues between supervisors and workers about safety as they go about their work. They demonstrate genuine interest in worker safety, build trust, and surface hazards and concerns that workers might not raise in a group setting.

Question 24: What is a toolbox talk and what is its purpose on a construction site?

A meeting to discuss which tools to purchase
A short, focused safety briefing on a specific topic, delivered to workers to raise awareness and reinforce safe working practices (Correct answer)
A formal disciplinary meeting about safety breaches
A weekly management meeting about site progress

Correct answer: A short, focused safety briefing on a specific topic, delivered to workers to raise awareness and reinforce safe working practices

A toolbox talk is a short (typically 10-15 minute) informal safety briefing focused on a specific topic relevant to the work being carried out. Its purpose is to raise awareness of hazards, reinforce safe working practices, communicate lessons learned, and maintain a positive safety culture.

Question 25: What information should a site induction specifically cover for new workers who are unfamiliar with construction sites?

The payment and expense process
Only the site's commercial programme
The procurement process for materials
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 26: What does the hierarchy of control measures specify as the most effective method of controlling risk?

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

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 27: What is the significance of adequate welfare provision in preventing occupational ill-health?

Welfare facilities have no effect on occupational ill-health
Adequate washing facilities prevent skin absorption of hazardous substances; clean rest facilities prevent ingestion of toxins; changing facilities prevent take-home contamination of family members (Correct answer)
Only the provision of RPE prevents occupational ill-health in construction
Occupational ill-health is prevented only by PPE, not welfare provision

Correct answer: Adequate washing facilities prevent skin absorption of hazardous substances; clean rest facilities prevent ingestion of toxins; changing facilities prevent take-home contamination of family members

Welfare facilities are a primary route for preventing some occupational diseases. Washing removes skin contaminants before eating; changing facilities prevent work clothing contaminating home environments; clean rest areas prevent ingestion of substances from contaminated hands.

Question 28: In a method statement for excavation work, what specific hazards must be addressed?

Collapse of excavation sides, striking underground services, proximity to structures, water ingress, access and egress, falling objects, and fumes in deep excavations (Correct answer)
Only the type of soil
Only the risk of falling in
Only the depth of the excavation

Correct answer: Collapse of excavation sides, striking underground services, proximity to structures, water ingress, access and egress, falling objects, and fumes in deep excavations

Excavation method statements must address multiple hazards: collapse of sides (requiring support or battering back), striking underground services (requiring service plans and CAT/Genny scans), proximity to adjacent structures, water ingress, safe access and egress, falling objects, and hazardous atmospheres in deep excavations.
