    • b. A specified piece of mechanical equipment is isolated, and it is safe to apply blocking and go to work.A Clearance shall be issued only to a worker who is authorized to PSSP category 5 or 6. (Page 85)
  28. What is the procedure for extending a Clearance to another worker?  What type of worker can the Clearance be extended to?
    The protection provided by a Clearance may be extended to another authorized worker through a Protection Extension.  The worker receiving a protection extension must be certified to at least PSSP Category 3. (Page 85)
  29. Can a Clearance be issued on a line or equipment on which a Test and Work Permit has been issued?
    A Clearance shall not be issued on a line or equipment on which a Test and Work Permit has been issued. (Page 86)
  30. Because of the hazard of backfeed from station voltage transformers (VTs) and Station Service transformers, for work within station perimeters, a Clearance shall not be issued unless _________________________.
    such transformers have first been rendered safe against backfeed. (Page 86)
  31. How is a Test and Work permit different from a Clearance permit?
    Worker Protection Grounding/Bonding and blocking devices shall remain in place except during the tests. Gapped grounding devices shall be used where practicable. Where gapped grounding isn’t practicable, a cable may be floated for splicing and terminating. Not more than one Test and Work Permit shall be issued or be in force on the same conductor or equipment at any one time. While a Test and Work Permit is in place, a Clearance (including Protection Extensions), or Self Protection shall not be permitted on the same conductor or equipment. Before work is resumed on conductors or equipment on which tests have been conducted, the Test and Work Permit holder shall ensure that safe working conditions are established, including the re-establishment of Worker Protection Grounding/Bonding or blocking, and shall advise their crew of anychanges in conditions from those that were in effect prior to the tests. (Pages 97-101)

    Mimic displays. Safety tagging. Safety Protection Guarantees. (Page 47)
  81. A PSSP mimic display may consist of a combination of what?
    A PSSP mimic display may consist of a combination of dynamic or static display boards, electronic displays (with a paper copy for backup), operating one line diagrams, or Distribution operating diagrams. For example, the PSSP mimic display could consist of a mimic display board on a wall used as the main display, supplemented by operating one line diagrams in a folder.

    Note: some display boards at ACC's and those at substations are for operational purposes only and are not PSSP mimic displays.
  82. T or F – At central control facilities with computer based controls, the PIC may use a system of electronic displays for generating stations, transmission lines, substations, distribution systems, etc.
    True. (Page 49)
  83. With regards to switching, when is the mimic display tagged?
    The mimic display is tagged after the switching is completed and before the SPG is issued.   (Page 50)
  84. Is tagging part of the Switching process or the SPG process?
    Tagging is part of the switching process not the SPG process.
  85. T or F - Each device must remain tagged on the mimic display until the Safety Protection Guarantee, Live Line Permit or Assurance of No Reclose Permit is cancelled and the associated field tags are removed.
    True (Page 51)
  86. What are the requirements for multiple SPGs with common isolation points?
    Where multiple Safety Protection Guarantees are issued with common isolation points, each guarantee will have its own set of tags on the mimic display, as specified in SPR 604.2c.  (Page 51)
  87. What does the designation “(3)” mean when indicated next to a device on a One-line diagram?  What does this mean with respect to hanging tags in the field?
    On the three phase Power System(s), station devices such as disconnects with individual phase motors operators must be shown on the mimic display as one device even though they consist of three individual single phase components. The alpha-numeric designation of such a device on the mimic display and operating one line diagrams must be followed by a “(3)” to indicate the three components. For PSSP tagging purposes the mimic display will be tagged with only one tag. Each motor operated single phase components will be individually tagged in the field. Switching orders and safety protection guarantee forms must identify three tags in the field by indicating (3) following the device designation i.e. 5D21(3).
  88. Can Operating One-line Diagrams be used as Mimic Displays?  What is the procedure for doing this?
    Yes. Operating one line diagrams will be marked up to show the tagging of isolating devices not shown on the mimic display. Isolation points on the appropriate diagram being used as the mimic display will be enclosed by a colour coded line drawn on the diagram. The isolation zone will be identified on the diagram by means of a dated notation referenced to the Safety Protection Guarantee. Red colour coding will be used to indicate clearance tagging and blue for Test and Work Permits. Any operating one line diagram used as part of the mimic display will show tags in effect for the portion of the station displayed on the diagram.

    De-tagging will be done by stroking out the dated notations. The diagrams will be replaced as necessary and all tagging still in effect will be transferred to the replacement diagram. If the PIC is required to tag level V isolating points which are not shown on operating one line diagrams, information can be transferred from station mechanical or electrical drawings as a sketch or as a listing of the equipment and then tagged on to operating one line diagram.
  89. T or F – Operating one line diagrams that form part of the PIC’s mimic display will be clearly stamped with the words “MIMIC DISPLAY”.
    True.  (Page 54-55)
  90. When are Distribution Operating Diagrams used as Mimic Displays?
    Distribution operating diagrams will be used to tag Distribution devices not shown on a Distribution mimic display. Distribution operating diagrams which are used as the mimic display will be tagged as outlined in 3.3 of this operating order. Distribution operating diagrams that form part of the PIC’s mimic display will be clearly stamped with the words “MIMIC DISPLAY”.
  91. What is a Combination Display?  What are the rules around tagging of Combination Displays?
    When the mimic display consists of a combination of displays and the isolation points for a Safety Protection Guarantee are represented on more than one display, a caution tag marked “PSSP” with a note referencing one display to the other must be attached to each display.
  92. What Level of equipment is shown on PSSP Mimic Displays (not including Distribution Operating Diagrams used as Mimic Displays)?
    Level 1through Level 4
  93. T or F – Operating authority will be assigned for all power system equipment.

  101. Can a worker apply Self Protection tags on Level IV equipment inside a SPG zone of isolation?
    Yes. When the level IV equipment is within the boundaries of a Level V isolation point, Self Protection may be used when the SPG is established at the Level V device. (Pages 16-17)
  102. Can a worker apply Self Protection tags on Level V equipment inside a SPG zone of isolation?
    Yes. When the level IV equipment is within the boundaries of a Level V isolation point, Self Protection may be used when the SPG is established at the Level V device. (Pages 16-17)
  103. What must be done if an unsupported field tag is discovered?
    If a tag is discovered unsupported by a mimic, the matter will be referred to the PIC, and then by the PIC to the PIC’s manager. The manager or PIC will undertake a thorough investigation and then the PIC can authorize removal of the tag if appropriate. A written record of such investigation will be forwarded to the Chair of the PSSP Review Committee. (Page 108)
  104. Explain the Repeat Back Procedure.
    When a PIC issues operating instructions (e.g. operating of switches, valves or gates) or Safety Protection Guarantees via verbal instructions, or instructions sent electronically (by fax or email), the worker shall repeat them back to the issuer word for word and shall receive acknowledgement (repeat back procedure). The PIC must make certain that all information is specific and follows the intended sequence of operation. Personnel receiving instructions or permits must repeat the information back, word for word, and receive acknowledgment.(Page 108)
  105. What two components does PSSP training consist of?  Explain fully the Modules of training for the System Component.  What is Local Component?
    The training for each PSSP authorization category consists of a system component and a local component.The system component training requirements are detailed in Modules 1A, 1B, 2, 3, 4, 5, and 6 of this operating order. The PSSP Computer Based Tutorial and Testing package includes a review of PSSP orders, training modules and relevant sections of SPR. It includes a series of standard tests to confirm the worker’s comprehension of the PSSP material. For new PSSP authorizations in Categories 2 and 3, instruction provided by the self-paced Computer Based Tutorial (CBT) is sufficient. New authorizations in Categories 4, 5 and 6 require instructor-led classroom training or its equivalent before writing the final exam(s).
