PTS Sentinel Scheme and Fitness 5 — Questions and Answers
Question 1: Under what circumstances can a Sentinel card be suspended by the scheme administrator?
- Only if the cardholder requests a voluntary suspension
- If the cardholder fails a drug/alcohol test, loses required medical fitness, or has a serious competence-related incident (Correct answer)
- Only following a formal criminal conviction
- Suspension is not permitted — only full cancellation is allowed
Correct answer: If the cardholder fails a drug/alcohol test, loses required medical fitness, or has a serious competence-related incident
Sentinel cards can be suspended for drug/alcohol failures, loss of medical fitness, or serious safety incidents while an investigation is conducted.
Question 2: A worker's Sentinel card is approaching its expiry date. What must happen for them to continue working on or near the line?
- They can continue for up to 30 days past expiry while renewal is processed
- They must complete the required renewal process — including any medical and competence updates — and receive a valid new card before the expiry date (Correct answer)
- Their supervisor can issue a temporary written extension
- Expiry only affects new worksites, not existing assignments
Correct answer: They must complete the required renewal process — including any medical and competence updates — and receive a valid new card before the expiry date
Working with an expired Sentinel card is not permitted; renewal must be completed and a valid card issued before the expiry date to avoid a gap in authorisation.
Question 3: Which of the following scenarios would most likely trigger a post-incident drug and alcohol test under the Sentinel Scheme?
- A worker arriving slightly late to a briefing
- A near-miss event or collision involving a track worker on the operational railway (Correct answer)
- Routine end-of-shift sign-out
- A worker requesting to change their assigned task
Correct answer: A near-miss event or collision involving a track worker on the operational railway
Post-incident testing is mandatory after safety-critical events such as near-misses or collisions to determine whether impairment was a contributing factor.
Question 4: A PTS worker moves to a new employer. Which statement about their Sentinel card is correct?
- Their card is cancelled and they must reapply from scratch
- The Sentinel card belongs to the individual, not the employer, and remains valid — the employer link is updated in the system (Correct answer)
- They must re-sit all competence assessments for the new employer
- The new employer must issue a company-specific card
Correct answer: The Sentinel card belongs to the individual, not the employer, and remains valid — the employer link is updated in the system
Sentinel is a portable, individual-held scheme; the worker retains their valid card and competences when changing employers, with the employer association updated in the database.
Question 5: What is the significance of a 'fitness for work' self-declaration that some employers require before each shift?
- It replaces the need for a Sentinel medical review
- It places a legal duty on the worker to confirm they are free from impairment and fit to work safely on that specific day (Correct answer)
- It is only required for workers over 55 years of age
- It is optional and has no formal safety status
Correct answer: It places a legal duty on the worker to confirm they are free from impairment and fit to work safely on that specific day
Daily self-declarations hold workers legally and professionally responsible for confirming they are fit on the day, complementing (not replacing) periodic medical assessments.
Question 6: How does fatigue management relate to the Sentinel Scheme's fitness requirements?
- Fatigue is not addressed by the scheme as it is considered a personal matter
- Workers and employers must manage working hours and rest periods to ensure workers are not impaired by fatigue before accessing the track (Correct answer)
- Only night-shift workers are subject to fatigue management rules
- Fatigue only applies if the worker has been on site for more than 12 consecutive hours
Correct answer: Workers and employers must manage working hours and rest periods to ensure workers are not impaired by fatigue before accessing the track
Fatigue impairs reaction time and judgment similarly to drugs or alcohol; the Sentinel Scheme requires workers to be rested and employers to control shift lengths accordingly.
Question 7: A Sentinel cardholder is working overseas for six months and does not use their card during that period. What should they be aware of upon returning?
- The card is automatically cancelled after 90 days of non-use
- Competences may have lapsed if not kept current, and the employer should review whether any refresher training or reassessment is required before the worker returns to trackside duties (Correct answer)
- No action is needed — the card remains fully valid indefinitely
- They must re-sit the initial PTS assessment regardless of how long they were away
Correct answer: Competences may have lapsed if not kept current, and the employer should review whether any refresher training or reassessment is required before the worker returns to trackside duties
Extended gaps in practice can affect competence currency; the employer and worker should review requirements before returning to trackside duties even if the card has not technically expired.
