työnkorkeus

Työnkorkeus refers to the vertical position at which a worker performs tasks, particularly in manual or industrial settings. It is an ergonomic concept that helps define the optimal range of movement and support for the human body to reduce fatigue, musculoskeletal strain, and injury risk. In practice, workers may encounter a variety of working heights, from floor level and low tables to elevated platforms, ceilings, and roofs.

Measuring and controlling työnkorkeus involves several steps. First, assess the task and determine the required posture and movements. Next, record the average elbow and hands level relative to the worker’s height. Common guidelines suggest that tasks should be within a horizontal reach of 45–75 cm from the worker’s midpoint, with elbows slightly bent and wrists in a neutral position. When tasks require repetitive motions or high forces, a lower working height is preferable, especially for shorter workers. For taller workers, a slightly higher working height may be acceptable as long as the range stays within the recommended limits. Frameworks such as the European Standard EN 1005‑2 provide detailed recommendations for safe working heights in construction and other occupations.

Proper use of ergonomic tools—adjustable workbenches, oscillating platforms, and mechanical lifts—can help maintain työnkorkeus within an acceptable range. Training programs that emphasize correct task design and the importance of maintaining appropriate working heights are integral to occupational safety. By paying attention to työnkorkeus, employers can decrease the prevalence of repetitive strain injuries, improve productivity, and comply with national and international health and safety regulations.
