10 Commandments

Dear All-knowing Frog,

I read with great interest your June 9, 2010 post describing the greatest rejuvenation safety risks at …

It is clear that injection is much safer than replacement and that the steps Novinium has taken to make rejuvenation safer still are substantial and impressive, but what can be done to mitigate the risk of electrical contact?  Do you have any rules or insights from which I may learn?


Praying in Provo

Dear Devout-one,

I sought, and was granted, guidance by the highest of authorities.  When it comes to safety we share all of our best practices with anyone that would like to learn.

The very first Novinium Value is Safety.  It states: 

Safety is our first priority.  We provide an ever–improving safe work environment for our team members, our customers, and the public.”


The greatest safety risk we face is electrical contact.  If the ten commandments below are followed the team will be safe from all known electrical hazards.  If an individual decides to ignore one or more of these commandments that individual is not welcome on the Novinium team.  Ignoring any of these 10 commandments endangers life.


Before the ten commandments are revealed to us we should understand the following defined terms so that we may understand the word of frog:

Affirmative Acknowledgement:  100% of the team including any visitors must repeat verbatim a proposed switching action and state that they concur that it is safe to proceed with the proposed switching action.  When more than a single individual is at a location one individual can speak for all present if the spokesman makes eye contact with the others and receives a verbal acknowledgement from each.  The spokesman must indicate by name the concurring team members and visitors.

Dielectric Gloves:  Properly tested and dated gloves with a rating which exceeds the greater of (a) the phase-to-phase operating voltage of the equipment to which you are exposed, (b) customer standards or requirements, and (c) 20kV.

Energized:  Cables or equipment where line voltage is known to be present.

Potentially Energized: Cables or equipment believed to de-energized whether or not grounded, which may become energized by the action of others.

Potentially Energized Injection Equipment:  Injection equipment which is physically connected to any Energized or Potentially Energized electrical cable or equipment.  Examples include, but are not limited to (a) dielectric tubing which is connected to live-front or dead-front, (b) feed or vacuum bottle connected to tubing in (a), (c) vacuum pump connected to the vacuum bottle in (b).

Visibly Grounded:  A visibly grounded cable’s contiguous and unburied length can be seen to the point where the conductor is grounded.



1.   Wear rubber within four (4) feet of the uncovered zone – Never let any part of your body within 4 feet of uncovered, Energized or Potentially Energized equipment without:

a.   Dielectric Gloves,

b.   Dielectric boots,

c.   Eye and face protection as required for the system voltage,

d.   Flame Retardant (FR) clothing rated at or above the exposure hazard, and

e.   Rubber sleeves, if the equipment includes exposed primary live-front.

2.   It is not dead until it is grounded – Starting only from an energized state, always test to confirm a deenergized state and ground the equipment which will be necessary to touch without Dielectric Gloves.  Changing elbows, installing IAs, performing TDR and RF testing, and changing splices are examples where it is necessary to touch equipment without Dielectric Gloves.

3.   Deenergize live-front equipment – Always deenergize and ground live-front equipment before performing any other work.

4.   Rubber up and cover up – Cover all exposed Energized or Potentially Energized equipment.  The cover-ups must be placed so that all required work can be performed without breaking the plane of the cover-ups with any tool or body part, whether or not the body part is rubbered-up.

5.   If you can’t cover it, deenergize it – If it is not possible to apply covers as required by the fourth commandment, the equipment must be deenergized.

6.   Spike cables before cutting – Always spike a cable on which the conductor is not Visibly Grounded before cutting it.

7.   Communicate with Affirmative Acknowledgements – Always provide warning and receive an Affirmative Acknowledgement when:

a.     A primary switching operation to deenergize a piece of equipment.

b.     An equipment test is about to be conducted to confirm a deenergized state.

c.     A status test (energized or deenergized) is complete.

d.     A ground is to be applied.

e.     A ground has been applied.

f.      A ground is about to be removed.

g.     A ground has been removed.

h.     A switching operation is about to be made, whether or not the operation will energize any equipment.

i.      A switching operation has been completed.

8.   Always use a hot stick – Never use your hands to manipulate any Energized or Potentially Energized equipment.

9.   Have a plan; work the plan – Never proceed without a clear and accurate print.  Never proceed without clear and accurate switching instructions.  Never deviate from the prescribed instructions without proper authorization.  Everybody on the job site must discuss and understand the work and switching plan for the day.  If the plans change, stop work and meet at the tailboard again to revise the plan for the balance of the work.

10. Always check your PPE – Check your gloves, footwear, hot sticks, electrical testing devices, dielectric blankets, hardhat, eye and face protection, grounds, AED, and first aid equipment.

In future posts to the Frog Blog I will evangelize more about these ten commandments.

Follow these ten commandments religiously and you too may someday be granted access to the big marsh in the heavens,
