<!-- SECTION: Summary -->
## What is NLE Calc?

NLE Calc is a utility developed by the CDC that calculates the Recommended Weight Limit (RWL) based on the Revised NIOSH Lifting Equation. It provides metrics for assessing physical stress, specifically the Lifting Index (LI) for single tasks and the Composite Lifting Index (CLI) for multiple tasks. The app is intended to help users evaluate workplace lifting hazards to mitigate the risk of musculoskeletal disorders.
