Assessment of biomechanical risk at work: practical approaches and tools

Cocca P., Marciano F., Rossi D.

Acta of Bioengineering and Biomechanics

2008

Vol. 10, nr 3

21-27

The paper illustrates some methods and tools supporting work-related risk assessment with reference to ergonomics and biomechanics, in particular. These aspects will also be described through the analysis of two case studies in order to highlight the main characteristics and problems found during the application phase. Furthermore, using modelling and simulation software, the utility and reliability of such tools in support of the work-related risk assessment will also be evaluated.

Job Level Risk Assessment Using Task Level ACGIH Hand Activity Level TLV Scores: A Pilot Study

Drinkaus P., Sesek R., Bloswick D. S., Mann C., Bernard T.

International Journal of Occupational Safety and Ergonomics

2005

Vol. 11, No. 3

Existing upper extremity musculoskeletal disorder analytical tools are primarily intended for single or monotask jobs. However, many jobs contain more than 1 task and some include job rotation. This case/control study investigates methods of modifying an existing tool, the American Conference of Governmental Industrial Hygienists (ACGIH) Hand Activity Level (HAL) Threshold Limit Value (TLV), to assess the upper extremity risk of multi-task jobs. Various methods of combining the task differences and ratios into a job level assessment were explored. Two methods returned significant odds ratios, (p < .05) of 18.0 (95% CI 1.8–172) and 12.0 (95% CI 1.2–120). These results indicate that a modified ACGIH HAL TLV may provide insight into the workrelated risk of multi-task jobs. Further research is needed to optimize this process.
