PTS - Personal Track Safety Lookout and Warning Systems Flashcards

When a lookout is positioned to warn workers, what is the MINIMUM distance ahead of an approaching train the lookout must be able to see?

Answer: 1,000 feet

A lookout must have an unobstructed line of sight of at least 1,000 feet in the direction of approaching train traffic to provide adequate warning time.

Which of the following is a valid reason to suspend lookout and warning system operations temporarily?

Answer: Train traffic has been halted by a train dispatcher for a defined period

Operations may be suspended only when a train dispatcher has formally halted train movements for a defined period and this is confirmed.

A worker notices the lookout has moved out of their designated position. What should the worker do?

Answer: Stop work and clear the track until the lookout is back in position

If the lookout is not in their designated position, protection is compromised and all workers must stop and clear the track.

What action must a lookout take if they are uncertain whether an approaching object is a train?

Answer: Warn workers as if it is a train

When in doubt, the lookout must issue the warning immediately, treating any uncertainty as a confirmed train approach.

During a warning drill, workers fail to clear the track within the required time. What is the correct follow-up action?

Answer: Immediately conduct another drill until workers respond correctly

If workers do not respond correctly in a drill, the drill must be repeated until the correct response is consistently achieved.

Which factor most directly determines how far in advance a lookout warning must be given?

Answer: The speed of approaching trains and the time workers need to clear

Warning time must account for both the approach speed of trains and the time required for all workers to reach a place of safety.

A lookout stationed on a curve has restricted sightlines. What is the appropriate response?

Answer: Add a second lookout positioned to cover the restricted sightline

When a single lookout cannot see far enough due to curves or obstructions, additional lookouts must be added to ensure full coverage.
