Manual Materials Handling (MMH) represents a significant part of the tasks carried out by workers across several economic activity sectors. However, there is a big discrepancy between working conditions and workers actual needs and limitations, and this reflects in the high rate of work-related disorders, particularly, the low back pain, due to incorrect MMH. Ergonomics plays an important role in order to reduce risks associated with MMH tasks, to improve workers safety and health, and, consequently, to raise awareness in organizations and society. It is within this scope, that the present study is presented. It aims to analyze and evaluate risks associated with MMH tasks using four risk assessment methods (MMH Guide, Key Indicator Method, Manual Handling Assessment Charts and Comprehensive Lifting Model). For that, four MMH tasks carried out in two workplaces in the luggage rooms at an airport in Portugal were evaluated. A questionnaire was also developed and applied in order to characterize the sample under study and to understand the company practices regarding MMH. Based on the results obtained, improvement measures were proposed, which can reduce or eliminate the risks associated with the tasks studied, like the implementation of automated or semiautomated loading systems or auxiliary lifting systems.
