Biosafety Cabinets/Fume Hoods
Working in Biological Safety
Cabinet (BSC's) or fume hoods requires
laboratory personnel to assume a variety of
awkward postures due to limited work access,
which restrict arm movement, and therefore
significantly increase the amount of stress on
joints of the upper limbs, neck and back, Hence
exposure to a variety of ergonomic risk factors.
|Associated Risk Factors:
- Repetitive motions of the
hands, wrist, and forearms,
especially when pipetting is
- Constrained knee and leg space,
especially in fume hoods and older
- Contact pressure on the
forearms, wrists and knees, or
- Awkward and static posture of
the neck, torso, legs, arms and
- Constrained body position,
overloading muscles, tendons, and
joints in asymmetrical manner.
- Working with elbows winged.
- Prolonged standing in unnatural
positions or in restricted

Always assume a proper posture.
