Four workers were injured when a steel beam collapsed at a Chicago construction site on Dec. 29. An investigation into the incident by the Occupational Health and Safety Administration (OSHA) is pending.
According to the Chicago Tribune, three of the workers were standing on the beam Monday morning when a pair of bolts sheared off, causing the workers to drop 15-20 feet to the ground. A fourth worker was injured by the falling debris. Three of the workers were listed in serious-to-critical condition, while the fourth was listed in fair-to-serious condition. Initial reports indicate all of the necessary safety measures were in place.
