The right to exercise control over an assigned portion of the power system to establish the conditions for and to issue SPGs, LLPs, ANRPs

The right to exercise control over an assigned portion of the power system

The PIC is the person that has been assigned both Operating Authority and Operating Responsibility for an assigned portion of the Power System

A piece of equipment/conductor that has had its normal source of hazardous energy removed by opening and securing switches/ cutouts/ line disconnects/ bus disconnects (tagging/locking)

An assurance that conductors or equipment are isolated and will remain so

A duly stated and logged guarantee between PICs of different Operating Authorities that a switch will be  opened, secured, and remain so

With 'Do Not Operate' tags on the isolation points

The 'normal' distances for qualified electrical workers

A qualified worker authorized to PSSP Cat 5

• -In all operating instructions, words are specific and follow intended sequence of operation
• -clear and precise terms must be used
• -the 'repeat back method' must be used

A permit that allows work on energized conductors or equipment

• Distances for:
• -qualified workers operating uninsulated equipment
• -unqualified workers when continuously directed by qualified workers
• -workers qualified specially trained(arbourists)

Under direct and continuous supervision of a qualified electrical worker, vehicles and equipment are permitted to drive underneath exposed, energized electrical conductors and overhead equipment maintaining their LOA

A stated and duly logged guarantee between two PICS of two different Operating Authorities that a Reclose device is turned off, secured(not be reclosed) and will remain so

Accepted as satisfactory in reference to experience, training, education, personal competency, physical ability, and familiarity with rules, procedures, equipment, and dangers involved in the work or the operation

• -a permit must be obtained from the PIC
• -the person receiving the LLP must be qualified
• -all reclosing devices must be disabled and tagged
• -there must be means of direct communication between the PIC and Permit holder
• -in case of de-energization, the LLP holder must be contacted before re-energization
• -the circuit involved shall not be paralleled without notifying the LLP holder

The distances for unqualified workers and their equipment

The distances that shall be maintained between workers(including their extensions of reach caused by conductive tools) and exposed energized electrical conductors and equipment

An SPG issued by the PIC which is a guarantee that a conductor or equipment is isolated and will remain so

• -Clearance
• -Test and Work
• -SelfProtection

• -A written procedure for checking on the well being of a worker when working alone in hazardous situations
• -Pre-determined call in times must be established
• -If the worker check authority is unsuccessful in contacting the worker, they will initiate a rescue response

• -BCHydro operating orders
• -the required constraints applied to the power system to provide worker protection from power system hazards

• -the worker must be PSSP Cat 3
• -the existing Clearance is appropriate for the work being done
• -the worker must know all the associated hazards
• -the workers name, date and time must be recorded

• The 'absolute' limits for a qualified worker
• -with a detailed work plan
• -for a specific purpose

• -Only authorized workers or those accompanied by an authorized worker may enter
• -Their time of entry and exit must be recorded in the Station Log

• Avoiding
• Eliminating
• Controlling

Having been approved for specific access to the power system by an authorized manager

A permit to work near energized conductors or equipment

Proper work practices and approved, tested, and well maintained LL tools

In the case of emergency to protect life and prevent injury

The semaphore position of adjacent CB

Appendix C

• -ensure the status of their portion of power system is accurately represented on mimic display
• -direct field staff in switching Level 1-4 equipment
• -maintain the official log
• -confirm the holder of an SPG(authorized to cat 5)
• -authorize work on their portion of power system

• Worker tests for zero potential
• Worker applys grounding/bonding

System Locks

• Log used by PIC to record:
• Switching(system operation)
• SPG's
• LLP's
• ANRP's

A document that indicates permanent changes to a distribution system

• Control room
• communications equipment
• mimic displays
• logs, tags, OO's
• instructions
• documents
• records

• mimic displays
• safety tagging
• SPG's, LLP's, ANRP's

• After switching is completed
• Before SPG is issued

Tagging is a part of the switching process

• Yes
• color coded isolation points enclosed by color coded lines indicate isolation zone
• dated, signed notation and SPG information included

Used by two PICS to move the operating boundary to bring lines/equipment all within one area 

Any electrical, mechanical, hydraulic, pneumatic, chemical, or thermal energy, or force such as gravity that could potentially harm workers

Current representation of operating status of electrical system

• Individual motor controlled switches require a (3) to indicate this
• Each motor requires an SPG tag
