description

The aim of this study is to perform physical workload analysis in metal processing industry operations (assembly operators, packaging operators and inspection staff) using objective ergonomics research methods based on the heart rate monitoring and muscle fatigue. The study was carried out in a medium sized metal manufacturing enterprise in Latvia in the department of manufacturing of ironing boards. Assembly, packaging operators and inspection staff agreed to take part in the objective heart rate monitoring and muscle myotonometry measurements. Results show that workers are at high risk of developing WMSDs, since they are subjected to heavy manual work and load on muscles during work. Accordingly to the heart rate analysis the assembly operators and packing operators can be subdivided into heavy work category, but inspection staff- in moderately heavy category. Myotonometry investigation results confirm muscle fatigue and heaviness of physical workload.
