At a construction project, workers were removing concrete cut out from a pre-fabricated sewer pipe to install a manhole. A chain was supposed to be attached to the piece of concrete and a backhoe to prevent it from falling. But the chain hadn’t yet been attached to the backhoe when the piece gave way and fell down. A worker was hit by the falling concrete and suffered multiple injuries. Another worker received a minor injury. The construction company pleaded guilty to failing to ensure that every part of a project was adequately braced to prevent any movement affecting its stability or causing its failure or collapse and was fined $65,000 [Wasero Construction (1991) Ltd., Govt.
