Description of this graphic and how it will be used to illustrate the methods we use to reduce risk in LLW
13 Procedures and Rules
RULE: Safe Conditions for Work No work shall be done on electrical apparatus, or systems which may have electrical, dynamic or potential energy, unless safe conditions for work are provided by one of the following methods:
the apparatus is isolated and de-energized in accordance with “lock-out / tag-out” OR Live Line (e.g. Rubber Glove) Techniques are used This rule is a ‘corner stone’ to safe work
15 Lock-out / Tag-out
We use our Utility Work Protection Code for situations when we need to work on circuits that are isolated and grounded
Guaranteed ‘OPEN’ devices are locked and/or tagged
16 Controlling Authority
The centralised Control Room has operating control over all switchable devices They receive applications for the establishment of work protection from the various trades groups They write the switching orders and establish the isolated zone with field support
17 Establishing Work Protection
The Trade groups establish work protection by operating the switchable devices and placing tags and, when possible, locks This is done under the direction of the Control Room Trade groups test for potential and apply temporary grounds
18 Lock-out / Tag-out
De-energizing grounds must be visible to the worker at all times If they can not see a set of grounds, then they must install another set at their work location
20
Bracket and Point of Work Grounds
B WORK LOCATION
Circuit is potential tested and then Bracket Grounds are installed
WORK LOCATION A
21
Bracket and Point of Work Grounds

WORK LOCATION A
Point of Work Grounds are installed if Bracket Grounds are out of sight
22 Lock-out / Tag-out
All apparatus that has been isolated using Lock-out / Tag-out must be potential tested and grounds installed before work is begun
24 Rubber Glove Rule
PowerStream employees comply with the ‘Ground to Ground’, ‘Lock to Lock’, ‘Boom Rest to Boom Rest’ Rule It states they can not leave the ground or open or enter an cabinet or enclosure unless we have on the appropriate class of rubber glove
This rule is another of our ‘corner stones’ to safe work
25 Rubber Glove Rule
We have the appropriate class gloves whenever we climb a pole with spurs, go aloft in an aerial device or open an enclosure, like a padmount transformer Compliance with this one rule has saved lives and reduced the number of serious injuries significantly
27
Job Planning and Tailboard Conference Discussion
Job Planning Every job is pre-planned Pre-planning includes a documented Tailboard Discussion between all the crew members All crew members participate in this important job safety process
28
Conducting a Tailboard Conference Discussion
The crew gathers at the job site and together discuss:
The Job Steps and who is doing which part of the job Job Hazards and the Barriers used to reduce risk of hazard causing injury
29
Conducting a Tailboard Conference Discussion
Once crew agrees on the safe work methods (job steps) and what barriers will be used, they put their signature on the documented TBC sheet
