Abstract: At 11:15 a.m. on May 26, 2017, an employee was working at a warehouse loading dock using an industrial truck to load a truck. The employee had not engaged the vehicle restraint system which secures the truck to the loading dock (Rite-Hite Dok-Loc vehicle restraint). When the employee attempted to engage the Dok-Loc, the warning light turned red and the audible alarm indicating the lock had not engaged sound. The employee turned off the audible alarm and began loading the truck. Because the Dok-Loc vehicle restraint had not been engaged the truck was not secured against movement during the loading operation and the truck driver had a green light to pull away. At approximately 11:20 AM the employee walked from loading dock #3 onto the back of a truck to place a packing slip on the load inside the truck before the truck pulled away. The truck began to pull away from the loading dock just after the employee had stepped onto the back of it. The employee stated that he tried to fall into the truck, but the truck was moving uphill so the employee jumped and fell off the back of the truck approximately 4 feet to the concrete ground landing on his feet. The employee's knees were injured and the employee's legs buckled and fell to the ground. The employee sustained a complete ACL tear and partial MCL tear to the left knee, a tibia plateau fracture to right leg, a sprain of ACL in right knee. The employee was hospitalized. The employer notified DOSH on 5/27/17 at approximately 3:45 pm, which did not meet the reporting requirement. DOSH opened an inspection on 9/21/17. The employer manufactures and assembles medical testing kits and assays for hospitals and laboratories.
