A worker is asked to move 30 boxes from a desk onto a shelf within 3 minutes (assume there is enough space and no other lifting work within 8 hours). The shelf height is 55 inches, and the desk height is 30 inches. The initial horizontal distance from the box to the body is 7 inches. Assume that all the boxes are in the same size (8 inches edge, cube), each weigh 20 lb., and have well designed handles. Is there any lifting risk according NIOSH lifting guide

The following information is available for a seeded 5-day BOD test conducted on a wastewater sample. 15 mL of the waste sample was added directly into a 300-mL BOD incubation bottle and then 285 mL of dilution water was added to fill the bottle. The initial DO of the diluted sample was 8.8 mg/L and the final DO after 5 days was 1.9 mg/L. 1. Assuming that the BOD5 of 285 mL dilution water is 0 mg/L. What is the 5-day BOD (BOD5) of the wastewater sample 2. In reality, the dilution water usually has its own BOD. In a control experiment of determining the BOD5 of dilution water with seed microorganisms, the initial DO of dilution water was 9.1 mg/L and the final DO after 5 days was 7.9 mg/L. What is the 5-day BOD (BOD5) of the wastewater sample
