On July 25, 2000, a 33-year old male journeyman lineman died, and a co-worker was injured, after they were struck by a car that drove through a utility construction work zone that was beside the road. The utility lineman (the fatal victim) and the injured co-worker were working with a team of county public utility workers to frame and install a new power pole near an intersection of two county roads. The driver of the intruding vehicle drove past the work zone signage and flagger into the work site. After traveling past the flagger station, the intruding vehicle crossed the opposing traffic lane and shoulder of the road and headed straight into the work zone. The injured co-worker was struck and thrown about 10 to 15 feet onto the grass in the work area. The worker who died struck the hood and windshield and was thrown over the top of the intruding vehicle striking his head on the asphalt pavement of the intersecting road. A witness, who was stopped at one of the flagger stations, immediately called 911 for emergency assistance. Both victims were treated on site and transported to a local emergency room. The fatal victim was airlifted to a trauma center later that day and died of his injuries 10 days later. To prevent future similar occurrences, the Washington State Fatality Assessment & Control Evaluation (FACE) investigative team concluded that power and utility companies and similar operations working along highway and road construction work zones, should follow these guidelines: 1. Employers should use positive protective barriers to shield workers from intruding vehicles. 2. Use an audible warning/alarm system to alert workers of a work zone intrusion or other emergency. 3. Use portable rumble strips/speed bumps on roadways to warn motorists of highway construction work zones. 4. Use law enforcement vehicles and personnel to help alert vehicle traffic to highway work zones. 5. Develop and utilize both Traffic Control Plans and Internal Traffic Safety Plans for each highway and road work zone project. 6. All highway and road construction projects must meet or exceed MUTCD guidelines and must follow all State, County and Municipality requirements for traffic control, set up, and application.
