Answer:
51 pounds.
Step-by-step explanation:
The NIOSH lifting equation always uses a 51 lb (23.13 kg) load constant (LC), which represents the maximum recommended load weight to be lifted under ideal conditions, for most patient lifting tasks. From this starting point, the equation uses several variables expressed as multiplier coefficients (in the equation, M = multiplier) that serve to decrease the constant load and calculate the RWL for the particular survey task.
