This study was conducted in a logistics warehouse, where 197 tasks across nine locations were evaluated using REBA, RULA, BAuA, and LMM-ZS. Data were collected through on-site observations and task-specific video recordings. Risk scores were normalised to a 0-100 scale to enable cross-method comparison. Multi-method evaluations create two main challenges: selecting the most suitable method for each task and integrating outcomes derived from incompatible scales. To address these issues, a harmonised framework is proposed that standardises score ranges and categorical zones across the four methods.eninfo:eu-repo/semantics/closedAccessMulti-method risk assessmentREBARULABAuA and LMMArticle10.1080/00140139.2025.2608270WOS:0016566956000012-s2.0-10502799475441505739Q2Q1
