PTS - Personal Track Safety Positions of Safety Flashcards

What is the minimum distance from the nearest rail that constitutes a position of safety on a plain line with no structures?

Answer: At least 2 metres from the nearest rail of any running line, on level ground with no obstructions

The minimum position of safety is at least 2 metres from the nearest running rail on a plain line, providing clearance from the train body, air pressure effects, and any projecting objects.

What is the correct posture a worker should adopt when standing in a position of safety as a train passes?

Answer: Stand side-on to the line with feet parallel to the rail, both feet firmly on the ground, and hold any tools firmly downward

Workers should stand side-on to the approaching train, feet parallel to the rail and firmly planted, holding tools firmly downward to minimise profile and ensure stability against the air pressure wave.

When working in a tunnel, how should positions of safety be identified?

Answer: Refuges in tunnels must be formally identified, numbered, and communicated to all workers in the site brief — workers must know the location of the two nearest refuges in each direction

In tunnels, refuges must be formally identified, their locations communicated to all workers in the site brief, and each worker must know the two nearest refuges in each direction before work begins.

What should a COSS do if a designated position of safety becomes compromised during the work (e.g., blocked by equipment)?

Answer: Immediately suspend work, reassess the safe system of work, identify a new position of safety, and rebriefed all workers before allowing work to resume

If a position of safety is compromised, work must be suspended immediately and the safe system of work revised to identify and brief workers on a new, adequate position of safety.

How does working on an adjacent line while trains run on a neighbouring line affect the position of safety requirements?

Answer: Workers on a blocked line must still maintain a position of safety clear of any adjacent running lines when trains pass on those lines

A line blockage on one line does not protect workers from adjacent running lines. Workers must move to a position of safety clear of all running lines when trains pass on adjacent lines.

What hazard does a 'live rail end protection board' provide and where must it be positioned?

Answer: It is positioned over the end of the third rail at the boundary of an isolation, warning workers not to go beyond that point where the third rail becomes live again

A live rail end protection board is placed over the end of the third rail at the boundary of a traction isolation, warning workers that beyond that point the third rail is live and must not be approached.
