Risk Assessments

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

• AIdentify the hazards✓
• BEvaluate existing controls
• CImplement new safety measures
• DRecord findings

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?

• AProvide lifting belts to all workers
• BEliminate the hazard or substitute the task with a mechanical alternative✓
• CIncrease workers' awareness through training
• DProvide first aid kits

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?

• AOnly the site manager
• BThe workers who perform the tasks, health and safety representatives, and other relevant parties✓
• CThe local police
• DOnly experienced workers

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:

• ABuying new machinery
• BHigh-risk construction activities such as working at height or confined spaces✓
• CRecruiting new staff
• DScheduling site meetings

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?

• AFile the assessment and never review it
• BImplement the controls and monitor their effectiveness✓
• CReview the assessment only if an accident occurs
• DAssume all risks will be managed by workers

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
• BWait until the annual assessment review
• CRevise the risk assessment to address the new hazard and implement appropriate controls✓
• 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 hazards
• BIdentify who might be affected
• CEvaluate existing control measures
• DIdentify the colour of the site cabins✓

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?

• AOnly when an inspector visits
• BAt least annually and whenever work significantly changes✓
• CNever, once completed
• DOnly if workers complain

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 workers
• BThe client
• CThe employer or contractor undertaking the work✓
• DThe HSE

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 they work without checking
• BThrough regular inspections, observations, incident monitoring, and worker feedback✓
• COnly measure effectiveness annually
• DAsk workers if they feel safer

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 formal annual review of all site hazards
• BAn ongoing, real-time process identifying and controlling hazards as work activities change throughout the day✓
• CA risk assessment completed by external consultants every quarter
• DA one-time assessment before a worker starts employment

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 document worker attendance
• BTo authorize and control high-risk activities by ensuring hazards are identified and control measures are confirmed before work starts✓
• CTo track subcontractor costs
• DTo satisfy insurance policy requirements

Answer: A PTW is a formal authorization 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.
