?LP uses a Trim Waste Conveyor System designed and manufactured by Teal Sales, Inc. to collect and discharge waste produced in the OSB structural panel manufacturing process. (Pretrial Order, Attach. C ¶¶2, 3.) The system operates nearly 24 hours per day, seven days per week, and an operator and utility employee are present on each shift. (Tr. 41.) One component of the system is the #4 conveyor, which collects trim, transports it along the belt, and discharges it. (Tr. 135, 151; Ex. R-24 [conveyor and unguarded ingoing nip point at time of injury], Ex. C-9, Ex. C-10 [view of conveyor after injury].) The #4 conveyor is a sliding belt conveyor, which means the belt runs in a continuous loop. (Tr. 136.) One end of the conveyor rotates under power and the unpowered lower or tail end holds the loop tight. (Ibid.) Trim from an upper conveyor drops onto the lower end of the #4 conveyor, which transports it up an incline. (Tr. 151.) The collected trim eventually ends up in a grinding machine. (Ibid.)
