Bluewater PowerBluewater Power Distribution Corporation, the utility providing electricity distribution and related services in the Sarnia-Lambton area, has been fined $120,000 in the 2012 death of a worker who was performing repair work following the aftermath of Hurricane Sandy.

The worker was one of two who had been assigned post-storm repair work on Passingham Drive in Sarnia, where trees had downed power lines. On October 31, 2012, the two workers cleared tree limbs and began to repair the electrical lines. One worker was working from an aerial bucket while the other was working from the ground, and they began working on the downed primary neutral line.

Up until that point, the worker in the aerial bucket had been working with leather gauntlet gloves and was preparing to make the final connection by fastening the neutral end to a connector that completes the circuit path. That worker called down to the other to bring rubber gloves from the cab of their truck. While the worker was heading to the truck cab to retrieve the rubber gloves, the truck shook and the boom of the bucket dropped.

The supervisor was immediately called and both ambulance and the fire department were summoned. The worker in the bucket was taken to hospital and could not be revived. Cause of death was determined to be electrocution.
An investigation revealed that no job plan or tailboard was in place prior to the commencement of work. A job plan is typically prepared by a power line technician when the technician arrives at the job site in order to assess the work that needs to be carried out. A tailboard conference - or job site planning meeting - is used to review the job plan, identify hazards and determine how to best mitigate these hazards before work begins.

Job planning and documentation of a tailboard is a requirement under the Electrical Utility Safety (EUSR) Book, Rule 107. These rules have been established as a minimum standard for safety precautions to be followed by employers and workplaces that do not fall under the jurisdiction of Ontario Regulation 851/91 (the Industrial Establishments Regulation) or Ontario Regulation 213/91 (the Construction Projects Regulation).

In this instance, a properlyestablished job plan and tailboard conference would have addressed some of the key hazards and safety failings present at the site. In a statement, the worker who was on site indicated that a job plan was normally completed prior to the project; it was not completed in this instance because they were anxious to bring the power back to the community.

Although both workers had over 20 years of experience each and had been trained on the importance of wearing rubber gloves at all times upon stepping into the aerial bucket on a boom truck, the job plan and tailboard conference would have reiterated the need for using rubber gloves at all times when working on any pole or structure carrying energized conductors. The worker had been wearing leather gloves, which have a reduced electrical resistance compared to rubber gloves. Following the incident, the worker's gloves were found to contain some dampness, which would have further weakened their resistance to electricity.

The workers should have taken the measure of treating the neutral conductor as energized ("live") as indicated in Rule 116 of the EUSR Book.

Bluewater Power Distribution Corporation pleaded guilty to failing as an employer to ensure that workers performed a documented job plan before performing work on or in proximity to energized electrical equipment in accordance with Rule 107 of the EUSR.

Today we are all concerned with the energy we consume within our homes. But how many truly understand the ins and outs of home energy use, and where exactly does the electrician and the development of energy management systems come into play. There is much to consider when discussing home energy use. The consumer first off needs to be informed about energy use, how it is calculated and ultimately billed if they are to make changes to their energy consumption rates. But in terms of educating consumers does the residential electrician have a role? And beyond that are manufacturers developing products designed to help electricians and consumers better understand residential energy use? Throughout this article we will deal with each of these important questions.

Jeremy Herrington

Total Electrical Solutions was founded in 2013 by Jeremy Herrington in Quispamsis, on the outskirts of Saint John, New Brunswick. Since 2013 Jeremy has steadily grown Total Electrical Solutions in the residential, commercial and construction sectors. The growth is primarily the result of Jeremy’s customer first philosophy, plus his over 20 years of industry experience.

Jeremy grew up learning about the industry from his father who was an electrical contractor. Jeremy spent his early years helping and watching his father as a contractor and business owner. After high school Jeremy was, like many, not wholly aware of the course he wished to take and so he began an electrical apprenticeship at his father’s company.
