PTS Safe Systems of Work 2 — Questions and Answers
Question 1: When a Safe System of Work (SSoW) is in place, who is ultimately responsible for ensuring workers comply with it?
- Each individual worker
- The Person in Charge (PIC) (Correct answer)
- The track owner
- The equipment supplier
Correct answer: The Person in Charge (PIC)
The Person in Charge (PIC) is responsible for ensuring all workers under their control comply with the Safe System of Work.
Question 2: What must happen BEFORE any worker is allowed to enter a 'Lookout Protected' working arrangement?
- A briefing must be given by the PIC explaining duties and escape routes (Correct answer)
- Workers must complete a written test
- The track owner must issue a written permit
- A minimum of three lookouts must be positioned
Correct answer: A briefing must be given by the PIC explaining duties and escape routes
Before starting work under lookout protection, the PIC must brief all workers on their roles, the warning signal, and the designated place of safety.
Question 3: Which document formally records the limits and conditions of a Safe System of Work on the railroad?
- The Weekly Possession Plan
- The Possession/Blocking Authority
- The Track Occupancy Permit or equivalent authority document (Correct answer)
- The Job Safety Analysis form
Correct answer: The Track Occupancy Permit or equivalent authority document
A Track Occupancy Permit or equivalent authority document formally defines the limits, times, and conditions under which the SSoW is granted.
Question 4: A worker discovers mid-task that conditions have changed and the current SSoW no longer adequately covers the risk. What should they do?
- Continue working carefully and report at shift end
- Stop work and inform the PIC immediately (Correct answer)
- Reduce working pace but stay within the SSoW limits
- Request additional lookouts and continue
Correct answer: Stop work and inform the PIC immediately
Any change in conditions that affects safety must be reported immediately to the PIC, who will reassess and modify or cancel the SSoW as needed.
Question 5: In the context of PTS, what is a 'place of safety'?
- The nearest signal box or control room
- A location clear of all lines where workers can stand without risk from rail traffic (Correct answer)
- Any area more than 6 feet from the nearest rail
- The designated break area established before work begins
Correct answer: A location clear of all lines where workers can stand without risk from rail traffic
A place of safety is a location that is clear of all lines and structures where workers are not at risk from passing trains or rail traffic.
Question 6: How does a Distant Lookout differ from a Lookout in a standard lookout-protected SSoW?
- A Distant Lookout is positioned further from the work site to give earlier warning (Correct answer)
- A Distant Lookout monitors only freight traffic
- A Distant Lookout works from an elevated position
- A Distant Lookout communicates only via radio
Correct answer: A Distant Lookout is positioned further from the work site to give earlier warning
A Distant Lookout is positioned further up the line to give additional advance warning when sight lines or train speeds demand more warning time.
Question 7: What is the minimum information a PIC must confirm before formally accepting a Safe System of Work authority?
- The names of all workers and their certification levels
- The limits, the line(s) affected, start and end times, and any special conditions (Correct answer)
- The identity of the train controller and emergency contact numbers only
- The equipment list and expected train frequency
Correct answer: The limits, the line(s) affected, start and end times, and any special conditions
Before accepting authority, the PIC must confirm the precise limits, which line(s) are protected, the validity period, and any special conditions attached.
