Worker Safety During Construction of the Golden Gate Bridge
This clip describes the installation of a safety net during the construction of San Francisco's Golden Gate Bridge on the order of bridge engineer Joseph Strauss. The clip suggests that the safety net - despite its cost - was a good investment as a morale booster, apart from the lives saved. Despite the net, there was a major accident later which caused the net to fall and cost several lives. Overall, the safety record was still better than might have been expected at the time.
