General musculoskeletal HHAs evaluate injury
risk associated with forceful muscular exertion, awkward posture, repetitive
motion, contact stress and fatigue. Frequently these risk factors are
encountered when handling loads and performing other physically demanding
tasks. Evaluators strive to apply objective analysis methods to
characterize risk and offer recommendations for mitigating risk and reducing
injuries.
Vibration/Mechanical Shock HHAs are a specialty
area that consist of applying objective methods to determine whether or not
exposures exceed established threshold limits. These investigations include
evaluating exposures confined to a specific region of the body such as when
the upper extremity receives vibration when using a powered hand tool but
may also include evaluating exposures to whole body vibration exposure such
that delivered to operators of heavy equipment and military vehicles. At
times assessments are requested for exposures to recoil from certain
weapons.
Blast Overpressure HHAs
are regularly requested to assess the potential risk of bodily injury from
exposures to blasts from munitions such as mortars, rockets, and other
explosives. These studies are conducted to ensure that injury risk is
minimized for personnel exposed to blast during the performance of their
duties.
