Inspections aim to prevent more dog electrocutions

Voltage hazards spark city action “ Boston Globe

The city will begin regularly inspecting electrical lines and junction boxes in an effort to eradicate stray voltage hazards like those that have killed several dogs, Mayor Thomas M. Menino said yesterday.

Starting this month, city departments -- including public works, transportation, and fire -- will begin a program of inspections that aims to survey a third of the city's electrical lines each year, adding up to a complete inspection of the city's electrical infrastructure every three years. The inspection schedule is based on recommendations issued by a city-appointed task force on electrical safety in July.

The city is also replacing metal housings on Boston's 30,000 traffic light control boxes with fiberglass covers, which don't conduct electricity.

Stray voltage has killed three dogs since 2000, including a 1-year-old boxer that was electrocuted in March while being walked by his 13-year-old owner. It also became an issue in the mayoral campaign when challenger Maura A. Hennigan accused Menino of neglecting the city.

Menino yesterday portrayed the program as an example of quick action by the city.

''When the issue of stray voltage was brought to the city's attention, we immediately took action," Menino said in a statement. ''The Stray Voltage Task Force is a critical component of our response, and the group will continue to monitor the city's electrical infrastructure."

The city, working with NStar, completed a survey of the city's electrical infrastructure this summer, inspecting more than 120,000 light posts, traffic signals, electrical and fire boxes, and metal plates located near electrical wires, city officials said.

Hennigan yesterday criticized Menino, saying the inspections should have come sooner.

''He should have been working on these issues since 2000," she said. ''Sadly, we have had many pets killed because of the fact that the city has not made this a priority."

Hennigan said the inspections should be mandatory, and completed each year.

''This is a serious issue as we approach the winter season," she said. ''We have a city that has aging infrastructure. Just because something is below the ground does not mean that everything is functioning properly. As mayor, I will show leadership and make sure we are provided with safe and efficient service."

Stray voltages are particularly problematic in the winter, when water from melted snow and ice can cause shorts and other electrical problems.

Sixty-six instances of stray voltages were found during the inspection this summer and were immediately repaired, said James W. Hunt III, the city's chief of environmental and energy services. The insulation and fiberglass plates are being installed as additional safety measures, he said.

''It's the mayor's strong feeling that one instance of stray voltage is too many," Hunt said.

  • Hello, Mike:

    Can you use a pocket AC tester to detect "stray voltage" of the type that electrocuted the dogs? If not, how did the city check for faulty leakage or exposure...presumedly...to dog urine streams. (Multimeter between frame, earthing conductor or the metal cover plate and the primary conductor?)

    As a Safety & Forensics Engineer I also have an extensive electrical/electronic background but haven't tested for this problem before. How will my answer come back? Email?

    Thanks.

    Ernie

    A pocket AC tester of the type designed to test for 5V or more is used by Consolidate Edison in New York city, because of the death of Jodie Lane. I don't think this is commercially available, but I suggest you contact Fluke and see if they have such a product in development. I know they have a pocket AC tester for 24V-90V.

    But a digital voltmeter and earth/concrete works just fine.

  • From the text Maura A. Hennigan's comments seem an unhelpful attack without value or leadership deployed.

    It appears Thomas M. Menino has taken good steps toward a Preventative Maintainance Program to rectify a recently discovered problem.

    Given the unique conditions and the age of the installations the few reported cases speak exceptionally well of our predecessors in installing Electrically Safe equipment.

    Does Maura intend to reap political reward from the work of Tom and identify herself as a technical leader or similar?

    Would you rather vote for someone who can compliment positive efforts of their potential predecessors?

    Just pondering.

  • A fiberglass cover will not stop a handhole from turning into an electrocution hazard if the handhole is filled up with saltwater from snow melting operations. In addition to cracks in insulation I have vacuumed out enough streetlighting handholes to know that saliva is semiconductive enough that you cannot electrocute a mouse by sticking 480 volts 3-phase into its mouth 1 wire at a time. Back inkindergarten I had a rabbit that liked to chew on 120 volts. Rottweilers are also the kind of animals that think that 120 volts is delicious. Now if you stick 480 volts up a mouse's armpit then the story will be rather different.

  • Replacing the covers with fiberglass covers is merely a band aid to the problem.

  • Mike, Since 1996-7, we have required our street lighting/ traffic signal electrical personnel to add a bond wire #6 copper from a lug on the cast junction box cover to the street lighting system ground wire, thus providing protection from this cover being energised from whatever source. Problem solved.

  • I am sorry to sound like a whiner but this really seems like a hypocrytical article. This is not a stab at your fine outfit as you are only spreading the information to the rest of us. I have never replyed to your articles because they are generally very informative and educational. Don't get me wrong, I am a proud owner/trainer of hunting lab retrievers and would feel ALMOST as sad if something happened to them as I would if something happened to my kids. Although, as far as I'm concerned, my kids are irreplacable, whereas I have replaced my hunting dogs on regular occassion with little more than lasting memories of the time I have spent in the field with each one and the pride that comes from watching a dog you had a hand in training figure out a new problem.

    I can't believe it takes PETS to get electrocuted before a city will make stray voltage hazard issues a priority. Does it not mean anything to city officials that this stray voltage is hazardous to our kids and us. I would think being a hazard to our own kids would make this more of a priority issue than simply being a hazard to our pets.

    Thanks for the continuing great articles.

    Shawn, I agree with you, but whatever it takes to place awarness, I'll take.

  • Las Vegas, Nevada has a similar problem caused by bad installations and lack of maintenance.
