PTS Safe Systems of Work 5

Question 1

What is the significance of a 'yellow flag' or 'caution flag' displayed in a work zone?

Accepted Answer

It warns approaching train crews to reduce speed and be prepared to stop short of workers or equipment

Answer

Yellow flags warn train operators to reduce speed and be prepared to stop, providing an additional layer of protection for workers in the vicinity.

Question 2

A PIC discovers that the track limits stated in their authority document do not match the actual location of the work. What is the correct response?

Accepted Answer

Contact the controlling authority immediately to clarify or correct the limits before any work begins

Answer

Any discrepancy in authority limits is a serious safety issue and must be resolved with the controlling authority before work commences.

Question 3

In a multi-line environment, a SSoW protects Line 1. A worker needs to briefly step onto Line 2 to retrieve a tool. What must happen first?

Accepted Answer

Appropriate protection must be confirmed for Line 2 before anyone steps onto it

Answer

No line should be stepped onto without appropriate protection in place; the SSoW for Line 1 does not cover Line 2.

Question 4

What is the primary purpose of a written 'Briefing Record' signed by all workers at the start of a job?

Accepted Answer

To provide evidence that all workers received safety information and understood the SSoW conditions

Answer

A signed briefing record demonstrates that every worker was informed of the safety conditions, responsibilities, and emergency procedures before work began.

Question 5

Which condition would make a lookout-protected working arrangement UNSAFE to use, regardless of other precautions?

Accepted Answer

Train speeds are too high for workers to reach safety after receiving a lookout warning

Answer

If train speeds are so high that there is insufficient time for workers to reach safety after a warning, lookout protection cannot be safely applied.
