Ergonomic Repetitive Task Analysis (ERTA)
Ergonomic Repetitive Task Analysis (ERTA) is a process used to
assess and improve the ergonomic aspects of repetitive tasks in the
workplace. It involves analyzing the tasks to identify potential risks and
hazards that could lead to musculoskeletal disorders or other injuries, and
then implementing measures to reduce or eliminate those risks. The goal of
ERTA is to improve efficiency, productivity, and workers’ well-being by
designing tasks that are more ergonomic and less likely to cause harm.
In ergonomic repetitive task analysis, factors such as the frequency,
repetitiveness, the intensity of task, the recovery time available to the
worker and overall duration of physical exertion are all considered.
Human energy expenditure is directly related to the physical demands
for the intensity of a task, which can impact the risk of musculoskeletal
injuries and overall work efficiency.
Focusing on assessments of the intensity of a task and required human
energy to complete the task, ergonomists can identify tasks that may be too
physically demanding or require excessive energy expenditure, which may lead
to fatigue and increased risk of injury and can recommend changes to work
practices, tools, or equipment to reduce physical strain and improve overall
efficiency and safety. |
