Dive summary:

• An alarm to warn of tipping danger had been filled with spray foam and wires appeared to have been disconnected before a Genie S65 boom lift rented from Hertz tipped over and killed a worker at a Canadian bridge project in 2011, a Hertz mechanic told a coroner's inquest in Canada's Northwest Territories.
• The mechanic, Tim Ebert, told the inquest he didn't think the wires could have been broken off by the impact of the fall, and that the sound-and-light alarm should have activated whenever the lift was on a slope greater than 4.5 degrees.
• Gustavo Argueta, 24, from Thunder Bay died in the June 2011 tip-over at the site where Teranorth Construction was working on a bridge over the MacKenzie River.
