Risk Assessments

What is the first step in the five-step risk assessment process?

• ARecord findings
• BEvaluate existing controls
• CIdentify the hazards✓
• DImplement new safety measures

Answer: The first step is hazard identification—determining what could cause harm. Only after identifying hazards can you assess who is at risk, existing controls, and necessary improvements.

A risk assessment identifies that manual handling poses a medium risk. According to the hierarchy of control, what should be considered first?

• AIssue lifting belts and back supports to everyone so the load can still be carried by hand as before
• BEliminate the hazard or substitute the task with a mechanical alternative✓
• CProvide first aid kits
• DRaise workers' awareness with a toolbox talk on lifting technique, leaving the task itself unchanged

Answer: The hierarchy of control prioritises elimination first, then substitution (e.g., using equipment instead of manual handling), then engineering controls, administrative measures, and finally PPE. Belts are low-priority PPE.

Who must be consulted during a risk assessment in the construction industry?

• AThe local police force, who must approve every construction risk assessment before work is allowed to start
• BOnly the site manager, because consulting the workforce would slow the assessment down unnecessarily
• COnly workers with more than ten years' experience, since newer workers cannot contribute useful information
• DThe workers who perform the tasks, health and safety representatives, and other relevant parties✓

Answer: Regulation 5 of the Management of Health and Safety at Work Regulations 1999 requires consultation with workers and safety representatives. Their input is essential because they understand actual work conditions.

A RAMS (Risk Assessment and Method Statement) document is most commonly required for:

• AHigh-risk construction activities such as working at height or confined spaces✓
• BScheduling site meetings
• CRecruiting new staff
• DBuying new machinery

Answer: RAMS is a detailed risk assessment and safe method statement mandatory for significant construction hazards like height work, excavations, and confined spaces. It's not required for procurement, HR, or administration.

What should be done after a risk has been assessed and control measures identified?

• AReview the assessment only if an accident occurs
• BAssume all risks will be managed by workers
• CFile the assessment and never review it
• DImplement the controls and monitor their effectiveness✓

Answer: Implementation and monitoring are crucial. Controls must be put in place and regularly reviewed to ensure effectiveness. Risk assessments are living documents requiring ongoing attention, not static records.

A site supervisor notices that a new hazard—vibrating power tools—has been introduced to the project. What should happen?

• AIgnore it as it's minor
• BRevise the risk assessment to address the new hazard and implement appropriate controls✓
• CWait until the scheduled annual review of the site risk assessments before recording the new hazard
• DOnly report it if someone gets injured

Answer: Risk assessments must be updated whenever significant changes occur (new processes, equipment, substances). Delayed reviews or injury-reactive approaches violate the duty to assess before work begins.

Which of the following is NOT one of the five steps in the standard risk assessment process?

• AIdentify the colour of the site cabins✓
• BIdentify the hazards present in the work activity and on the site
• CIdentify who might be harmed by each hazard, and how they might be harmed
• DEvaluate existing control measures

Answer: The five steps are: identify hazards, identify who is at risk, evaluate controls, record findings, and review regularly. Cabin colour has no relevance to health and safety risk assessment.

When must a risk assessment be reviewed under UK law?

• AAt least annually and whenever work significantly changes✓
• BOnly if a worker raises a formal written complaint about how a task is being carried out
• CNever; once an assessment has been signed off it stays valid for the whole life of the project
• DOnly when an inspector visits

Answer: Regulation 3 of the Management of Health and Safety at Work Regulations 1999 requires regular review and revision. Annual review is minimum; changes to work trigger immediate reassessment.

A construction firm is assessing risks for a new office renovation. Who is responsible for ensuring the risk assessment is competent and thorough?

• AThe employer or contractor undertaking the work✓
• BThe workers carrying out the renovation, each assessing their own tasks individually
• CThe Health and Safety Executive, which must inspect and approve the assessment first
• DThe client commissioning the office renovation, rather than the firm carrying out the work

Answer: The organisation carrying out work (employer/contractor) has the legal duty to conduct proper risk assessments. Clients, workers, and HSE support this but cannot substitute for the duty-holder's responsibility.

After control measures are implemented for a hazard, how should their effectiveness be monitored?

• AAssume the controls are working, since a competent person signed off the risk assessment when it was written
• BAsk a few workers at the end of the job whether they felt safer, and record that as the monitoring evidence
• CMeasure effectiveness once a year only, alongside the annual review of the site health and safety policy
• DThrough regular inspections, observations, incident monitoring, and worker feedback✓

Answer: Effective monitoring uses multiple methods: site inspections, near-miss reporting, accident data, and worker input. Assumptions or annual-only checks miss failures and emerging issues.

In UK construction, what is dynamic risk assessment and when is it required?

• AA one-time assessment before a worker starts employment
• BA risk assessment carried out every three months by an external consultant who visits the site and reviews the paperwork
• CAn ongoing, real-time process identifying and controlling hazards as work activities change throughout the day✓
• DA formal annual review of all site hazards

Answer: Dynamic risk assessment means continuously reassessing hazards as conditions change—e.g., weather deterioration, traffic patterns, or task modifications. It's not a scheduled event but an ongoing responsibility. External consultants and periodic reviews don't capture real-time changes.

What is the primary purpose of a Permit to Work (PTW) system on a construction site?

• ATo authorise and control high-risk activities by ensuring hazards are identified and control measures are confirmed before work starts✓
• BTo document who is on site at any time, so that attendance can be checked against the timesheets submitted by each subcontractor at the end of the week
• CTo satisfy the requirements of the site insurance policy, which will not pay out unless a signed form exists for every task carried out on the project
• DTo track subcontractor costs

Answer: A PTW is a formal authorisation system for hazardous tasks (hot works, confined spaces, live electrical work) ensuring that before work begins, all hazards are identified and controls verified. It's not an attendance or cost tool; insurance is secondary.

Under UK health and safety law, what must be established before a safe system of work is implemented for a complex task?

• AManagement approval only
• BPrecedent from similar projects
• CA risk assessment identifying hazards, evaluation of risks, and documented control measures to eliminate or reduce those risks✓
• DA meeting with the client

Answer: A safe system of work is built on documented risk assessment findings. Management approval supports implementation but doesn't establish the system. Client meetings and precedent inform but don't substitute for a formal assessment.

What is near-miss reporting in construction and why is it important?

• AMinor first aid incidents requiring bandages
• BWritten reports of injuries that have actually happened, which are filed with the Health and Safety Executive and kept in the site accident book
• CIncidents reported to insurers for claims
• DIncidents where no harm occurred but could have; reporting identifies system failures and prevents future injuries✓

Answer: Near-miss reporting captures incidents where circumstances or luck prevented injury, revealing safety weaknesses before someone is hurt. Injury reports, insurer claims, and first aid are separate. Near-misses are the 'near' events that precede actual harm.

Who is responsible for conducting the initial risk assessment for a construction activity under UK law?

• AAn external HSE inspector
• BThe Site Supervisor in every case, regardless of the trade involved, because they are the person present on site while the work is going on
• CThe Principal Contractor in every case, because the duty to assess cannot be passed down to the specialist contractor doing the work
• DThe person competent to assess the specific activity's risks, typically the relevant contractor or safety professional✓

Answer: Assessment competency depends on the activity. A roofing contractor assesses roofing risks, not the Principal Contractor directly. The Site Supervisor implements controls but may not assess specialist risks. HSE inspectors enforce, not assess for the site.

Under the Management of Health and Safety at Work Regulations 1999, when must risk assessments be reviewed?

• AOnly after an incident has happened, since there is nothing to learn from an assessment until something has gone wrong
• BEvery five years
• COnce per calendar year on a fixed date, regardless of any change to the equipment, the process or the people doing the work
• DWhen significant changes occur, periodically, or if assessment is no longer valid due to changed circumstances✓

Answer: MHSWR 1999 requires assessments to be reviewed when circumstances change (new equipment, process modification) or periodically. Rigid annual reviews miss new hazards; incident-only reviews are reactive; five years is too long for dynamic sites.

What is the difference between hazard and risk in construction safety context?

• AA hazard is the potential source of harm; risk is the likelihood and severity of that harm occurring✓
• BRisk refers only to financial loss
• CThey are the same thing
• DA hazard is a biological agent such as mould or bacteria, while risk covers every other kind of harm on a site

Answer: Hazard = the thing with potential to cause harm (e.g., excavation, electricity). Risk = probability of harm and its severity (e.g., electrocution, fatal injury). They are distinct concepts in risk assessment language.

Before implementing a new construction method, what must a contractor ensure happens?

• AThe risks are assessed, control measures documented, and workers understand the procedure before work begins✓
• BThe client approves the method
• CThe method is cheaper than previous methods
• DThe method is approved by the Principal Contractor

Answer: A new method must be preceded by risk assessment and documented safe system of work, with worker briefing before execution. Approval and cost are secondary; hazard control is primary. Client approval may be required contractually but safety assessment is always essential.

What does the 'hierarchy of control' require in construction risk management?

• ARisks are controlled in order: elimination, substitution, engineering controls, administrative controls, then PPE as the last resort✓
• BPPE is always the preferred control method
• CAll hazards must be completely eliminated
• DOnly the most obvious hazards need to be controlled, and less visible risks can be left to the experience and judgement of the workers involved

Answer: The hierarchy prioritises elimination (remove hazard), then substitution, engineering controls (design), administrative controls (procedures), and finally PPE. PPE is the weakest control, used when higher-level controls are inadequate. All hazards need consideration.

Under UK law, what must contractors do if the risk assessment for a task cannot be completed before work starts?

• AReduce the number of workers exposed to the task so that fewer people are at risk while it goes ahead
• BDelay work until a competent assessment is completed and control measures are confirmed✓
• CIssue additional personal protective equipment to the workers involved and let the task go ahead
• DLet the work go ahead and write the assessment up afterwards, using what actually happened on the job

Answer: Work must not commence until hazards are assessed and controls implemented. Proceeding without assessment violates the hierarchy and legal duties. Reducing workers or adding PPE doesn't address unidentified hazards.

How should contractors handle an identified hazard for which no effective control measure exists?

• ARely on worker training to manage the risk
• BContinue the work as hazard-free work is impossible
• CDo not proceed until a control measure or alternative method is developed, or work is prohibited✓
• DAccept it as an acceptable risk

Answer: If a hazard cannot be controlled to acceptable levels, work must not proceed. This respects the legal duty to manage risks and prevent harm. Training and acceptance don't eliminate uncontrolled hazards. Alternative methods must be found.
