PTS - Personal Track Safety Safe Systems of Work Flashcards

Which safe system of work is appropriate when line speed is too high for a Lookout-Warned system to be effective?

Answer: Blocked Line or train-free line guarantee

At high line speeds, a Lookout cannot provide sufficient warning time, so a blocked or train-free line guarantee must be used instead.

A PTS certificate holder who has not worked on or near the line for an extended period may need to complete what before resuming track work?

Answer: A refresher or reassessment to confirm competency

Prolonged absence from track work can erode competency, requiring a refresher or reassessment before returning.

What does the term 'cess' refer to in the context of PTS?

Answer: The area outside the rails used as a walkway or refuge

The cess is the area alongside the track, outside the running rails, used as a walkway and initial refuge.

Who is responsible for ensuring that workers under their supervision remain within the limits of the safe system?

Answer: The COSS or Engineering Supervisor in charge

The COSS or Engineering Supervisor is accountable for keeping all workers within the established safe system boundaries.

A worker who feels the safe system in place is inadequate should:

Answer: Raise the concern immediately with the COSS or Engineering Supervisor

Workers have a duty to raise safety concerns immediately with the responsible person on site before any incident occurs.

What is the purpose of the 'site protection' element within a safe system of work?

Answer: To prevent trains from entering the limits of the work site

Site protection controls train movements to ensure no train can enter the work area while workers are present.

Under PTS rules, which signal device is typically used by a Lookout to give an audible warning to workers?

Answer: A horn, klaxon, or whistle as specified in the local safe system

The specific audible warning device must be as specified in the safe working arrangements, but commonly includes a horn or whistle.
