Manual Handling & NIOSH Revised Lifting Equation Reference 2026

This dataset provides a structured reference for practitioners applying the NIOSH Revised Lifting Equation (NIOSH Technical Report 94-110, 1994) in manual handling risk assessments. It tabulates the Load Constant, each of the six task-variable multiplier formulas (HM, VM, DM, AM, FM, CM), the Recommended Weight Limit (RWL) composite formula, and the Lifting Index (LI) interpretation thresholds — all drawn directly from the peer-reviewed NIOSH publication. Alongside the NIOSH equation, the dataset includes the UK Health and Safety Executive Manual Handling Assessment Charts (MAC tool) risk band thresholds (green / amber / red / purple) as published by HSE, and references to the principal regulatory instruments: the UK Manual Handling Operations Regulations 1992 (MHOR 1992) and the EU Council Directive 90/269/EEC on manual handling of loads. These are widely cited in occupational health literature and workplace ergonomics training globally. Each row carries the authoritative source. Users must verify all values against the original publications before applying them in legal or compliance contexts. Exposure-limit tables for the FM (frequency multiplier) and CM (coupling multiplier) are described by reference only, as their full tabular form is copyright NIOSH/HSE; practitioners should consult the source documents directly. Dataset compiled 2026-05-28 for the SmartQHSE open ergonomics reference library. Verify all values against the authoritative source before use in any assessment or legal proceeding.
