PTS PTS - Personal Track Safety Risk Assessment and Method Statements 2 — Questions and Answers
Question 1: What is 'residual risk' in the context of a risk assessment?
- The risk that remains after all control measures have been applied (Correct answer)
- The original, uncontrolled level of risk
- A risk that has been fully eliminated
- A risk identified only after an accident has occurred
Correct answer: The risk that remains after all control measures have been applied
Residual risk is the level of risk that remains after all practicable control measures have been put in place.
Question 2: When should a risk assessment be reviewed and updated?
- Once only, when it is first written
- Regularly and whenever there is a significant change to the work or conditions (Correct answer)
- Only following a serious incident or injury
- Every five years as a minimum requirement
Correct answer: Regularly and whenever there is a significant change to the work or conditions
Risk assessments must be reviewed regularly and updated whenever the task, workforce, environment, or working conditions change significantly.
Question 3: Which of the following is NOT typically a hazard addressed in a PTS risk assessment?
- Moving trains
- Electric traction equipment
- Office workstation ergonomics (Correct answer)
- Slips and trips on uneven ground
Correct answer: Office workstation ergonomics
Office workstation ergonomics is not relevant to a PTS risk assessment, which focuses on hazards specific to working on or near railway tracks.
Question 4: What does 'likelihood' refer to when evaluating a hazard in a risk assessment?
- The severity of the injury if an accident occurs
- The probability that a hazard will result in harm (Correct answer)
- The total number of workers exposed to the hazard
- The cost of implementing a control measure
Correct answer: The probability that a hazard will result in harm
Likelihood refers to the probability or chance that a particular hazard will actually result in harm to a worker.
Question 5: When must a dynamic risk assessment be carried out?
- Only at the very start of a new project
- When unexpected hazards arise during work that were not in the original assessment (Correct answer)
- At the end of each working shift
- Only by the appointed COSS on the worksite
Correct answer: When unexpected hazards arise during work that were not in the original assessment
A dynamic risk assessment is carried out on the spot when unexpected hazards arise that were not identified in the original risk assessment.
Question 6: What is the significance of a 'significant finding' in a risk assessment?
- It means the risk is acceptable and no further action is needed
- It identifies a hazard requiring a specific control measure to reduce risk to an acceptable level (Correct answer)
- It automatically triggers an immediate work stoppage
- It must be reported to the police or emergency services
Correct answer: It identifies a hazard requiring a specific control measure to reduce risk to an acceptable level
A significant finding identifies a hazard that poses enough risk to require a documented control measure to reduce it to an acceptable level.
