Incident on Nov 30, 2021 (fatal): Employee is killed due to natural causes

At 7:30 p.m. on November 30, 2021, an employee, a waste treatment operator, was found dead next to an empty closed drum used to store Cascade 2, a sodium hydrosulfide solution. According to video surveillance, the employee was seen pushing an empty 55-gallon drum into the waste treatment area. The employee was not seen on the security camera again. A few hours later, a coworker was looking for the employee, and then found him lying unresponsive next to the empty plastic drum. The coworker that found the decedent usually received a briefing before relieving him of duty. The employee was killed due to natural causes. The employee suffered a cardiac arrest while on duty. There were no violations found. The worksite was an electronic circuit boards/components assembly and manufacturing plant. The waste treatment unit was responsible for maintaining and monitoring the wastewater treatment systems to maintain permitted discharge requirements before releasing the water back to the District (community) wastewater plant.

Incident on Jul 13, 2013: Employee falls down steps and injures hip

At approximately 10:30 a.m. on July 13, 2013, Employee #1 was working in the pla ting department of a technology facility. He decided to walk to the end of an ai sle in the strip etch processing area. There were a series of steps at the end o f the aisle. Additionally, a slip-sheet had fallen from its platform and onto th e floor at the end of this aisle. It was common practice of having a stack of sl ip-sheets on the platform and located at the end of this aisle. A slip-sheet was used as a spacer between each circuit board coming out of the production line, so that they are protected from damaging one another. The stack of slip-sheets w ere also located adjacent to a door that leads outside this building. Apparently , someone opened the door momentarily and a gush of wind may have blown one of t he slip sheets to the floor. The slip-sheet was also slippery. Employee #1 stepp ed upon the slip-sheet, lost his balance and fell down two steps. He suffered a serious hip injury and was hospitalized over 24 hours where he underwent a left femur IM rod fixation for left sub-trochanteric hip fracture.

Incident on May 25, 2010: Employee's finger caught in blade

At approximately 12:15 p.m. on May 25, 2010 Employee #1 was attempting to repair the lower vacuum pump unit for a plasma vacuum machine, after determining that there was an accumulation of dust causing operational problems. Employee #1 deen ergized and locked out the electrical power to the overall unit and removed the connection hose from the upper vacuum unit, to gain a limited access of about ei ght inches, to the opening of the lower unit. Employee #1 tried unsuccessfully, to manually unbind the rotary screw type vacuum assembly by reaching with his ha nd down into approximate five or six inch opening to the lower housing unit. Emp loyee #1 was assisted in the repairs by another coworker. The coworker removed t he exhaust hose leading from the units' lower plate, and applied a hose for Shop Vac, and turned it on, using the vacuum to collect loosened dust, while Employe e #1 applied compressed air from a hose nozzle to the top of the unit to loosen the dust. While the coworker continued to apply the vacuum from below, Employee #1 stopped the compressed air application, and again inserted his hand to attemp t to unbind the rotary screw assembly. When Employeee #1 freed up, the middle fi nger tip of his left hand got caught in the rotating screw veins. Employee #1 su ffered partial amputation including bone and tissue above the first knuckle join t.

Incident on Sep 17, 2009: Employee receives acid burns in chemical explosion

On September 17, 2009, an employee suffered burns after being exposed to sulfuri c acid due to improper mixing techniques that resulted in a chemical explosion. The employee was hospitalized and treated for acid burns.

Incident on Aug 5, 2007: Employee amputates finger in machine conveyor roller

On August 5, 2007, Employee #1 was assigned to clean circuit boards by placing t hem in a scrubber manufactured by Ishii-Hyoki. The employer is engaged in manufa cturing printed circuit boards. The scrubber has a slurry tank of aluminum oxide , measuring approximately 52-inches in diameter, located about eight inches unde r a waist-high box-like conveyor. Hoses from the tank feed aluminum oxide slurry (next to the conveyor box) are use to jet spray clean the circuit boards as the y are carried by the conveyor. A horizontally-oriented double strand 0.375-inch v-belt and pulley was located on top of the body of the tank. This powered belt and pulley mechanism rotates an arm within the tank to keep the slurry suspended . Employee #1 left his work station to bring back aluminum oxide for the slurry mix. Upon returning to the machine, he tripped and fell. As Employee #1 was fall ing, he put his hands out to catch himself. His right hand went behind a partial guard and entered the moving belt and pulley drive mechanism. Employee #1 pulle d his hand out and saw that the tip of his right pinky finger was amputated at t he distal joint. Employee #1 was released from the hospital after treatment for 28 hours due to an amputation and an open fracture of his right fifth finger tip .
