The issues of work hardness and intensity

Nedelyaeva A.V., Kasatkina L.N.

The paper presents research results on defining work hardness and intensity of merchandisers employed in Nizhny Novgorod division of the Wrigley Co. The merchandisers’ work involves the company products promotion, equipment assembly and installation, etc. Ergonomic, physiological and other techniques are applied in the course of research work. The Hygienic Factor Assessment Guide of R 2.2.2006-05 Working Environment is used to evaluate work hardness and intensity. The study results are based on the detailed data analysis received in working conditions evaluation of 10 males (aged 22-30) working for the Wrigley Co. A chronometry method establishes that merchandisers’ work hardness should be marked as class 3.2 (harmful work conditions), while the ultimate work hardness evaluation is marked in accordance with the highest hardness rate (lifting and carrying heavy objects (goods) and work in an uncomfortable position (half-bent or bending to the floor). The work intensity corresponds to class 2.0 requirements (allowable workplace exposure limits). At the end of the working day all the people in the group of interest show a 30% rise in the heart rate and 5% systolic blood pressure rise. To prevent harmful consequences, a number of recommendations has been worked out to optimize the working time management of the merchandisers in the Wrigley Company.

Keywords: merchandisers’ work hardness and intensity, ergonomic and physiological data (checking pulse and blood pressure).
