Methods for exposure measurement
It has been proposed [2] that mechanical exposure during
physical work should be described by three main
dimensions: level—intensity of the force, repetitive-
ness—the frequency of shifts between force levels and
duration—the time the physical activity is performed.
Any attempt to quantify exposure should therefore
include all the three dimensions for a worker being
assessed. Data should also be recorded for the other
important exposure factors, such as postural variation,
rate of movement and vibration, as well as the measure-
ment of psychosocial and organizational factors that may
be present in the workplace concerned.
