Abstract: At 4:00 p.m. on May 31, 2019, Employee #1 and coworkers were installing and applying wall texture to the drywall inside a new one-story residence. Employee #1, using an airless sprayer, had just finished applying a pre-coating to the interior walls. He moved his sprayer outside to clean it. The employee did not disconnect the sprayer from the power supply, nor did he place the trigger safety device, before he began to disassemble the sprayer. During this process, the sprayer activated and sprayed the employee's right hand between the thumb and index finger. The employee sustained a laceration approximately one-half-inch long. In addition, the liquid prep-coating in the gun was sprayed into the employee's hand. The employee initially refused outside medical treatment, but the following day he transported himself to the hospital, where he was admitted for treatment of the injured hand.
