This happened back in November of 2009 but it goes to show that radioactive leaks happen far too often. My first blog on the accidental release of radioactivity material centred around the Bruce Power Station. This particular blog takes place November of 2009 at the Darlington nuclear station in Clarington, Ontario.

A Nova Scotia maker of steel forms, used in construction, was fined $45,000 on August 21, 2009, for a violation of the Occupational Health & Safety (OHSA) In March 2008. A constructor was building an intake line from the Welland Canal to the Thorold Cogeneration power site. To do this, they needed to install a cofferdam, a structure built below water level that serves as a dry workplace. EFCO designed and provided the parts for the cofferdam. On March 28, 2008, the constructor had installed the cofferdam and was removing the water inside it when the cofferdam failed. No workers were hurt.
We all remember the scaffold accident that happened near the end of Christmas Eve day at the end of 2009. Metron Construction Inc. had 5 employees on their swing stage and it broke sending 4 out of the 5 employees to their death, 13 stories below. The 5th employee received 2 broken legs and a crushed spine.

Ontario’s Ministry of Labour is investigating a workplace accident that killed a 26-year-old man as he worked at a privately-owned quarry near Manotick. The man was working an excavator Thursday morning at 6107 First Line Rd., a jobsite owned by Green Valley Environmental, a waste water company specializing in septic system services. As he scooped up part of a 30-50-foot mound of rock and gravel with his machinery, it’s believed part of the pile collapsed, tumbling on top of him. The incident crushed the cab, with him inside. He was pronounced dead at the scene.
