Worker was injured last month by ‘erupted substances’

The April boom that startled people all over Sault Ste. Marie is being investigated by a provincial labour inspector.

"On April 30, 2024, the Ministry of Labour, Immigration, Training and Skills Development was notified of an incident that occurred at Algoma Steel Inc., in Sault Ste. Marie, on April 29, 2024," ministry spokesperson Anuradha Dhar tells SooToday.

"It was reported that a worker was injured by erupted substances," Dhar said.

"A ministry inspector has been assigned. As the ministry’s investigation is ongoing, we are not able to share further information at this time."

As SooToday reported last month, the noise was attributed by the company to molten slag encountering water from heavy rains in Algoma’s on-site slag reprocessing area.

The resulting reaction caused a fire in a piece of mobile equipment at the plant, causing one employee to be treated on-site for undisclosed injuries.

The noise was heard by residents in virtually every part of Sault Ste. Marie, and reportedly as far away as Goulais River and Heyden.

It was the latest in a series of slag/moisture incidents at the Sault steelmaker.
