Two employees of a contractor specializing in rebar construction were threading a 13.4-meter-long rebar into a wall on the roof deck of a new cast-in-place conc rete three-story medical office building. An overhead power line ran adjacent to the building. When the workers extended the rebar beyond the railing at the roo f deck edge, the rebar contacted the 16-kilovolt power line. The employees dropp ed the rebar onto the deck reinforcing, energizing it. The two workers received electric shocks and suffered first- and second-degree burns. The injured workers were treated at an emergency room, which was located across the street from the worksite, and released after 24 hours.

Incident on Dec 12, 2007: Employee injured in backward fall off column during pour

At approximately 7:00 p.m. on December 12, 2007, Employee #1, a journeyman-labor er working on the 29th floor of a building in San Francisco, climbed-up a column form to pour concrete. He had his positioning hook tied and connected onto a ve rtical bar on top of the column. Employee #1 was standing on a clamp of the colu mn's plywood form box and was pouring concrete into the column form by operating the nozzle of the concrete pumper. As he was working, Employee #1's weight caus ed the rebar to bend. His positioning hook suddenly slipped off the rebar projec tion and he fell approximately 6 ft backward onto the concrete flooring. Employe e #1 fractured his twelfth thoracic vertebra (T12); he was transported to St. Lu ke's Hospital, where he was treated for several days. Subsequent investigation d etermined that the accident resulted from a violation of T8CCR 1637(a) Scaffolds --General Requirements: Employees pouring concrete into column forms should be s tanding on a solid construction at least 20 in. wide, rather than on a clamps bo x. In addition, it was determined that the employer failed to provide other safe options for employees to stand on during pours, such as a ladder or a scissor l ift.

Incident on Jul 21, 2006: Two carpenters are injured when falsework collapses

On July 21, 2006, Employees #1 and #2 were working as carpenters for Webcor Cons truction, Inc., a construction firm that specialized in concrete work, at a jobs ite in San Francisco, CA. Their foreman was at the jobsite. As two workers from another employer were nearby, Employees #1 and #2 were moving a wooden frame kno wn as a "door-buck" into an opening within the rebar wall. The door-buck was con structed of 2-by-4s and 4-by-4s. It was approximately 3 feet by 5 feet by 7 feet long, and it weighed approximately 200 pounds. When it was in place, it would m aintain an opening while concrete was poured around it to form a wall. The insta llation of a door-buck would require that one end be lifted by hand and set onto the bottom of the opening. Then, the other end of the door-buck would be picked up manually and pushed into the opening of the rebar wall. Employees #1 and #2 were experiencing difficulty installing the door-buck. Two coworkers from a reba r subcontractor were in the vicinity. They tried to help Employees #1 and #2 lif t the door-buck and to push it into the opening. All four workers were positione d on a falsework platform that was a little below the bottom of the wall opening . At approximately 11:00 a.m., the falsework they were on collapsed. All four em ployees fell approximately 14 feet to the 7th floor concrete deck. Emergency med ical services were called, and the San Francisco Fire Department responded. All four of the workers were taken to San Francisco General Hospital. Employees #1 a nd #2 treated for contusions, strains, lacerations and bruises. Employee #1 sust ained the injuries to his legs, and Employee #2 sustained the injuries to his ey e. They were released later that same day. The employer was cited a general acci dent-related violation. T8 CCR CSO '1717 (a) (1) requires that falsework for the support of concrete or other materials shall be designed, erected, supported, b raced and maintained so as to assure its ability to withstand safely all intende d loads during erection, construction, usage and removal. The employer erected t he falsework. Normally, the door-buck had enough clearance for it to be easily p ushed into place. This incident occurred because the door-buck was especially di fficult to be placed into the opening. Therefore, the Citation was not classifie d as serious because of management's lack of knowledge. Other violations were ob served, and the employer was cited accordingly. This is the same accident discus sed in Accident Report 201183068. The workers injured in that accident worked fo r Reinforcing, Post-Tensioning Services, Inc.
