[Physiologic occupational study of changing technologies in refuse collection]. / Arbeitphysiologische Untersuchung veränderter Technologien bei der Hausmüllberäumung.

The strain on drivers and on driver's mates was investigated while emptying 1.1 m(3) containers by means of new dust compressing vehicles, and while removing dustbins of 2201 capacity. A classification was made on the basis of heart rates sampled during the whole shift by portable memories. Extrapolating for the whole shift, the authors measured heart rates of 106.0 min(-1) (drivers) from the 2201 technology. The complementary values from the 1.1 m(3) technology were 107.7 min(-1) (driver's mates) and 105.2 min(-1) (drivers). The men's physical endurance limit would be exceeded when they handled dustbins without break. The investigated tasks are classified to be heavy in both technologies.
