LETHAL ENERGY KILLS AGAIN
A high-voltage worker died from a fatal electrical shock while performing maintenance and repairs on a 3.8kV primary switchgear in a substation, reported Ontario’s Ministry of Labour (MOL).
The two main high-voltage infeed supplies were opened and tagged by the local electrical authority. The switchgear had two primary fuse compartments: one fed the in-service transformer while the other fed an out-of-service transformer (which had the fuses removed). The second transformer had been out-of-service for a long time and was assumed to have been disconnected from the secondary buss at some point. There were no up-to-date single-line drawings for the workers to use.
All potentials were verified as dead by both contractors on the job site. Temporary grounds were connected to the primary buss and system ground in the switchgear associated with the in-service transformer. All company procedures were in place and followed by the workers.
The repair work was required to repair damage from a flash-over in the primary fuse compartment due to excessive moisture. A generator was needed to supply the secondary 575 volts to the customer while repairs were being completed. The secondary leads were removed at the main transformer and the generator was tied into the secondary from the main 1000kVA transformer. The generator connections were made after checking of potential and installation of the temporary grounds.
The investigation showed that the secondary leads on the out-of-service transformer were still tied into the distribution buss from the building supply room. In this room, a Tie switch was present from a long-past owner of the building. The switch was in the closed position, supplying 575 volts to the secondary lines to which the out-of-service transformer was connected.
As a result, the second transformer was being back-fed, resulting in 13.8kV being present at the pothead conductors in the fuse compartment for the transformer. With no fuses present, there was no connection to the temporary grounds, allowing the potential to sit on the conductors. The aforementioned worker went into this compartment to move some equipment, made contact and was killed.
The MOL recommends that all potentials be verified before and after a temporary source of power is brought online. The temporary grounds should be applied to the line and load side of all fuses, even when fuses are not present in the primary circuit. These grounds will safely carry to ground any current from the conductors becoming inadvertently energized from an unknown source. MOL also suggests that up-to-date, single-line diagrams are present and legible.
VENTURE LIGHTING COMES OUT INTO THE OPEN
Venture Lighting has begun what it calls “a new relationship with the Canadian marketplace”. Up until this Spring, Venture says it has relied on other companies to promote and sell its products, but now it is waving its own banner.
As part of its stepping into the limelight, Venture is re-introducing the Ballastronix Inc. brand of magnetic HID ballasts (starting July 1), for which—says the company—it has had many requests. “This is the original Sola Canada product line that has been well established in this country for over 50 years!” said Greg Guisso, Venture’s Canadian sales manager, distribution.

HONEYWELL EXPANDS INTO THE PPE INDUSTRY
Honeywell signed a definitive agreement to acquire Norcross Safety Products LLC—a manufacturer of personal protective equipment (PPE)—for about $1.2 billion US. Norcross will be integrated into Honeywell Life Safety, part of the company’s Automation and Control Solutions (ACS) group. The agreement is subject to customary closing conditions, including regulatory review.
Roger Fradin, president and CEO of Honeywell ACS, said this acquisition provides Honeywell with a complete platform in a fragmented, global segment—one which is expected to yield substantial growth opportunities. Honeywell’s investment will allow them to fully participate in the broad and highly regulated industrial safety marketplace.
Norcross comprises the following three business groups: North Safety Products, W.H. Salisbury and Total Fire Group. CLICK HERE to visit them online.
WHAT WOULD IT TAKE FOR YOU TO GO SOLAR?
Ontario’s Solar Task Force launched a province-wide consultation with the public and the renewable energy industry on two specific questions:
What are the barriers to the installation and use of residential solar
hot water systems in Ontario and how can they be removed?
The task force has been asked to advise the government on how to meet its goal of achieving 100,000 new solar roofs in the province. Submissions are due by June 27. They should be a maximum of five pages in length and must include a name and contact e-mail or street address. Submissions can be e-mailed to email@example.com or mailed to:
