Excerpt from the OH&S Canada magazine

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.
