Falling load of steel prompted Muskrat Falls site shutdown

The contractor carrying out work at the Muskrat Falls construction site says Tuesday's shutdown was caused by a load of steel that fell the equivalent of four storeys.

Astaldi Canada, the contractor carrying out work at the Muskrat Falls construction site, says Tuesday's shutdown was caused by a load of steel that fell the equivalent of four storeys. 

"A load of steel was being hoisted by a crane and as a result of a rigging failure, the load fell to the ground from an approximate height of 40 feet," Matthew Pike, Astaldi's manager of external relations, said in a statement. 

Work at the site immediately stopped. 

No one was injured, although Nalcor Energy, which is supervising the Muskrat Falls project, described the case as a "serious safety incident." 

Work at the site will resume Thursday. Workers took part in a mandatory two-hour safety session, and will also be debriefed on Tuesday's near-miss.
