A 120 lb., 55-year-old female lifts a box with weight of 18 pounds from a position on the floor to a conveyor whose surface height is 25 inches from the floor. She lifts this box at a rate of four lifts per minute. The box, which has cutout handles at a distance of 7 inches from the floor, begins in a position 45 degrees to the right at a d in front of her at a forward distance of 18 inches. The worker performs this task constantly for 6 hours per day. Calculate the FIRWL and FILI for the start position.

Question
A 120 lb., 55-year-old female lifts a box with weight of 18 pounds from a position on the floor to a conveyor whose surface height is 25 inches from the floor. She lifts this box at a rate of four lifts per minute. The box, which has cutout handles at a distance of 7 inches from the floor, begins in a position 45 degrees to the right at a distance of 12 inches and ends directly in front of her at a forward distance of 18 inches. The worker performs this task constantly for 6 hours per day. Calculate the FIRWL and FILI for the start position.
