At the time this documentary was created, more than 600,000 workplace injuries occurred in the United States, with an additional 2,100 deaths attributed to on-the-job incidents. The film focuses on particular instances, beginning with a fishing boat that sank without warning in still water due to overfishing; then there’s a mining accident stemming from accumulated methane gas followed by a large explosion at a petrochemical facility in Texas. Through interviews featuring survivors and the families of those lost, the documentary's focus is squarely on businesses that disregarded safety protocols and regulators who failed to fulfill their responsibilities. The filmmakers attempted to get responses from both employers and government agencies, but were unsuccessful, so ultimately what we see is an examination of unacceptable practices where maximizing profit takes precedence. The archival footage does a good job of showing how complicated these operations are—for example, the sheer quantity of fish being processed in the Barents Sea or the extensive network of pipes, valves, and chimneys that make up an oil refinery—and it’s easy to understand how things can go wrong even under ideal circumstances, much less after years of deferred maintenance. The narration is somewhat understated, but there are some powerful moments, and it powerfully demonstrates just how easily systems can break down when safety measures are ignored.
