at approximately 10:00 a.m. on december 11 2013 employee #1 a carpenter foreman employed by pacific peninsula group was performing interior carpentry at a residential construction site. he was using a bosch 4000 stand-mounted benchtop table saw with a 10-inch blade to cut wood pieces for framing modifications. as he was making the first rip cut to a section of laminated wood product measuring approximately 16 inches long by 1.75 inches wide by 4 inches high his left hand contacted the blade. his left hand and fingers were severely cut. emergency services were called and the mountain view fire department responded. employee #1 was transported to stanford hospital where he was admitted and treated. his left middle finger which had been completely severed past the first knuckle near the palm was surgically reattached. the left ring finger which was severed through the bone past the first knuckle also was reattached but during a return hospital visit this finger required surgical amputation. this event was timely reported to cal/osha by the employer and also reported by the mountain view fire department. in its subsequent investigation cal/osha identified the employer as a construction management company performing as a general contractor for this residential apartment building project with tasks being performed by its own employees as well as subcontractors. the task employee #1 was performing required two rip cuts to the section of laminated wood product to achieve the desired finished piece because the blade was capable of rising only to approximately 3 inches high. employee #1 was working alone and no witness to the event was identified. the guard for the bosch 4000 included a hood a splitter and an anti-kickback device combined as a single unit. this guard/hood was at the site but employee #1 stated the guard was not installed on the saw at the time he began to plan and perform his cuts. employee #1 stated he set the rip fence to the right of the blade at approximately 1.25 inches and had no other anti-kickback attachments separate from the guard/hood available to install. he also stated he did not install any featherboards or jigs to use as he made cuts without the use of the guard/hood. employee #1 stated he was pushing and guiding the wood through the blade with his right hand positioned at the end of the wood length nearest to him and his left hand positioned on the top and at the end of the wood farther away from him. he stated there was no push block or push stick at the saw and he did not make one to use. he stated that the first cut was almost complete and the blade was about to come out at the back side of the wood piece when the wood kicked back and shot past his right side. he stated his left hand was extended behind and over the saw blade before the cut but was pulled back partially by the kick-back or his hand movement may have been reflexive. the result was that his left hand contacted the blade. the investigation report included a comment that the guard anti-kickback and spreader features of the bosch 4000 were not separable. they were designed to extend above and past the blade of the saw and would not have allowed the uncut portion of the wood piece to have passed. the first cut of the employee's two-step cutting plan was similar to a dado or cut where the blade does not extend through the top of the wood. the report concluded that the type of rip cut employee #1 was making was allowable without use of the blade's guard/hood only when additional protective devices such as featherboards were being used and separate anti-kickback devices had been installed. no protective devices such as featherboards or anti-kickback attachments were available or installed on the table saw during the time when the saw's guard/hood was not in place. no push sticks or push blocks were available during the time when the table saw was being used.

a power line crew was installing all dielectric self-supporting fiber-optic cable onto structures supporting an existing 69-kilovolt overhead power line. as part of the project the crew reinforced the existing structures and installed the fiber-optic cable. to install the cable the crew would hang sheaves use a pulling rope to pull the cable through the sheaves and permanently attach the cable to the structure. the employees would reinforce the existing structures by replacing some poles installing additional cross braces below the power line and installing supporting braces above the crossarm. the employees worked with the power line energized some of the time and deenergized at other times. the employer relied on employee work practices to avoid violating the minimum approach distance when the line was energized. however because of the placement of the braces and fiber-optic cable maintaining the minimum approach distance was not possible on most structures. one of the employees was completing the task of clipping in the fiber-optic cable on a two-pole structure while the power line was energized. the employee was attaching the cable to the structure with a housing that included a rubber boot and reinforcing rods. as the employee was wrapping the rods around the cable one of the rods got stuck. when he jerked on the 1.8-meter-long rod to free it it passed too close to the power line and current arced to the rod. the employee was electrocuted and set on fire by the electric arc. his coworkers conducted pole-top rescue lowered him to the ground and administered cardio-pulmonary resuscitation. their efforts were to no avail as the injured employee was pronounced dead at the scene.

a two-person crew was framing a single-phase utility pole to a three-phase pole. one of the employees bent back an armor rod then reached for the other part of the rod. either he brushed the armor rod (which presumably was on the energized phase conductor) or sweat poured from his glove onto the energized armor rod. the employee was electrocuted.

a three-person crew was tying a deenergized overhead power line to insulators on a crossarm on a utility pole. an energized 69-kilovolt overhead power line was also carried on this pole. two of the employees were belted off at a height such that the crossarm was at waist level. one of them the foreman on the job started to remove a 4- or 5-foot section of armor rod from a hand line. as he was removing the armor rod he raised it into contact with the energized power line and received an electric shock. the employees on the pole were not using electrical protective equipment nor were the energized lines protected from contact. the injured employee (who was hospitalized for his injuries) had about 1 year of experience at the time of the accident. the other two employees had 6 months and 3 months experience.

at approximately 10:30 a.m. on april 1 2013 an employee was working as a cabinet maker for a firm that manufactured and installed cabinets. the employee worked directly for the employer at the site. he was using a ripsaw to shorten pieces of lumber for the face frame of a cabinet. he was leaning against some moving lumber to help guide it through a self-feeding circular ripsaw. he was on the west side of the ripsaw leaning on the north side of the lumber that was against the fence where the stock was fed into the equipment. the equipment being used was a northtech model number nt-sl2000xl industrial ripsaw with serial number 0828003. because the employee was leaning against the moving stock he did not observe a splinter on the lumber. the splinter punctured the inner side of his left thigh for approximately 2 inches (50 millimeters) injuring his femoral vein. he was in the hospital for three days. the incident was reported by the employer to the bakersfield district office at 3:12 p.m. that same day.

on december 27 2012 employee #1 a 42-year-old drywall installer employed by grayhawk llc was working at a commercial building. he was working from a baker scaffold at an elevation of approximately 23 inches as he attempted to install wood sheathing (plywood) across a temporary exterior wall opening. employee #1 did not have the scaffold's casters in the locked position. as he attempted to screw in the plywood he reached forward away from the scaffold. the scaffold began to roll out from underneath him. employee #1 fell forward off the scaffold. his left thigh struck a structural upright member of the scaffold causing a large contusion and swelling. he finished his shift and commuted home. later that evening employee #1 went to the hospital complaining of pain and swelling in his left leg. he was admitted and surgery was performed to correct bleeding and a tear in his left superficial femoral artery. employee #1 remained hospitalized due to the formation of blood clots in his legs and lungs. on january 2 2013 employee #1 suffered a cardiac arrest likely due to the pulmonary clotting and died.

at approximately 3:00 p.m. on december 5 2012 a serious accident occurred at jobsite where employee #1 was engaged in drilling piles for a secant pile shoring system for an excavation. on the day of the accident employee #1 set a ladder up against a casing in order to attach the rigging from the forklift to the casing. the ground that day was muddy and about half way up the ladder the casing fell away from him. it hit the counterweight of the drill rig and ended up landing across his left leg and lower torso. employee #1 suffered a crushed pelvis a compound fracture of his left femur a severed femoral artery and a torn colon.
