Abstract: On Monday, January 25, 2021, an employee was working for a firm that sold and mounted tires. The employee was mounting an agricultural use tire on a forklift used at a dairy. Another worker at the firm provided a tire that was 16 in. (406 mm) in diameter. The rim on the forklift was 16.5 in. (419 mm) in diameter. After the employee had mounted the tire on the rim, he started filling it with air. He was using a clip-on air chuck. He was filling the tire to approximately 25 to 35 psi (172 to 241 kPa). The tire was on the floor. A coworker watching the activity instructed the employee to disconnect the clip-on air chuck. As the employee reached for the valve stem, the tire disintegrated. The employee suffered fractures to his left arm and wrist. He was hospitalized.
