ACCIDENT SUMMARY No. 70 Accident Type: Fall Weather Conditions: Clear/cold Type of Operation: New Building Construction Size of Work Crew: 2 Competent Safety Monitor on Site: Yes Safety and Health Program in Effect: Partially Was the Worksite Inspected Regularly: Occasionally Training and Education Provided: Yes Employee Job Title: Iron worker Age & Sex: 45-Male Experience at this Type of Work: 20 years Time on Project: 1 Week BRIEF DESCRIPTION OF ACCIDENT Five iron workers were distributing 90-foot-long open web bar joists on a building under construction. The bar joists were supported by vertical columns spaced 30 feet apart. The steel columns were not framed in at least two directions and the bar joists were not field bolted to the vertical columns to prevent collapse. The bar joists shifted, causing the vertical columns to lean. This caused entire section of columns and pen web bar joists to collapse. Two employees rode the iron down. One was fatally injured and one received serious injuries. INSPECTION RESULTS Following an inspection, OSHA issued citations for two serious violations of OSHA standards. ACCIDENT PREVENTION RECOMMENDATIONS The employer must: Ensure that during steel framing where bar joists are being used and columns are not being framed in at least two directions with structural steel members, the bar joists shall be field bolted to provide lateral stability during construction, in accordance with 29 Code of Federal Regulations Part 1926.751 (c)(1). Install a center row of bolted bridging to provide lateral stability during construction prior to slacking of the hoisting line where longspan joists or trusses, 40 feet or longer, are used, in accordance with 29 CFR 1926.751 (c)(2).
