#1. What is the primary purpose of a Permit to Work (PtW)?

To provide a written record of work undertaken on the gas network

To formally control work involving significant hazards by identifying risks and implementing suitable controls

To replace the need for a risk assessment where competent personnel are involved

To authorise any work activity taking place on operational gas assets

#2. Which of the following activities would be most likely to require a PtW?

Excavation adjacent to operational gas plant involving deep excavations

Routine inspection of a district governor by a Competent Person

Recording pressure readings at a telemetry kiosk

Monthly site housekeeping activities

#3. During preparation of a PtW, who should jointly review the risk assessment, method statement and proposed control measures?

The Responsible Engineer and Network Controller, as they oversee the operation

The Competent Person and work party, as they undertake the work

The Authorising Engineer and Competent Person, as they are responsible for planning and controlling the activity

The Network Controller and Competent Person, as they control the gas network

#4. A PtW activity has the potential to interrupt gas supplies to customers. Who should be informed?

The Competent Person only, as they control the site activities

The Network Controller and all affected or interested parties

The Responsible Engineer only, as they are accountable for SCO compliance

The contractor undertaking the work only

#5. Why is the Authorising Engineer normally required to attend site before authorising a PtW?

To witness the work being carried out

To independently verify that site conditions, hazards and controls align with the proposed permit

To undertake gas monitoring on behalf of the Competent Person

To brief the Network Controller on site conditions

#6. What is the maximum initial validity period of a PtW?

Seven calendar days

Seven working days, excluding weekends

Fourteen calendar days, subject to AE approval

The duration of the project

#7. How many extensions may be granted to a PtW?

Up to six extensions, provided the AE remains satisfied that the permit remains suitable

Unlimited extensions, provided the Competent Person remains unchanged

Up to three extensions before a new PtW is required

One extension only

#8. Why must the authorised PtW remain available on site during the work?

To allow inspectors to complete audits

To provide immediate access to the agreed controls, hazards, responsibilities and authorisations

To allow the Network Controller to review progress

To satisfy document retention requirements

#9. Which statement best describes the relationship between a PtW and an NRO?

A PtW replaces the need for an NRO where work is considered high risk

An NRO replaces the need for a PtW where network operations are involved

A PtW and NRO may operate together where both operational control and hazardous work control are required

Only one SCO document may be used at any given time

#10. Which option best reflects the purpose of the five-step risk assessment process?

To identify hazards, determine who may be harmed, evaluate controls, record findings and continually review effectiveness

To identify hazards, produce a PtW, commence work, monitor progress and close out documentation

To identify hazards, issue PPE, brief the workforce, complete the task and review performance

To identify hazards, obtain approval, undertake the work, complete records and archive documentation

#11. Who has responsibility for the site supervision and control of work being undertaken under a PtW?

The Authorising Engineer, as they authorised the permit and assessed the controls

The Competent Person, as they are responsible for implementing and maintaining the controls on site

The Responsible Engineer, as they are accountable for the SCO process

The Network Controller, as they control the gas network

#12. Why is it important to continually monitor site conditions during work covered by a PtW?

To confirm that operatives are complying with company procedures

To identify changes in conditions that could increase risk or invalidate the original controls

To allow the permit duration to be extended if required

To provide evidence for future audits

#13. A work activity requires atmospheric monitoring. Which document is normally used to record the results?

The NRO Register, as it records operational activities

The PtW, as all gas readings should be recorded directly on the permit

The RAT Form, as it provides a formal record of atmospheric testing and monitoring

The SCO Audit Form, as it records compliance with procedures

#14. Which information would be expected to form part of a properly completed PtW?

Details of the hazards, control measures, personnel involved and any relevant atmospheric test results

A copy of the Competent Person's training records and assessment certificates

Financial approvals, project costs and resource allocation

Details of previous permits issued at the location

#15. A Competent Person needs to leave site during work covered by a PtW. Which statement is correct?

The CP may leave provided another SCO registered person remains on site

The CP may leave after informing the work party and Network Controller

The CP should remain in control of the work unless off-site control arrangements have been specifically authorised by the AE

The CP may leave once the hazardous element of the work has been completed

#16. What is the maximum duration of an individual PtW extension?

Up to seven calendar days, provided the AE remains satisfied that the permit remains valid

Up to seven working days, excluding weekends

Up to fourteen calendar days, provided no changes have occurred

Up to the completion of the project

#17. During a PtW activity, the Competent Person becomes unavailable due to illness. What is the most appropriate course of action?
