Ergonomic hazards are workplace conditions that risk injuries to the musculoskeletal system, including repetitive and forceful movements, awkward postures, and exposure to vibration and extreme temperatures. Common types of ergonomic hazards include repetition, awkward posture, forceful motion, direct pressure, vibration, and extreme temperature. These hazards can lead to painful musculoskeletal disorders and other injuries.

1. ERGONOMIC
HAZARD

2. WHAT IS ERGONOMIC HAZARD?
• Refers to workplace conditions that pose the
risk of injury to the musculoskeletal system of
the worker.
• Include repetitive and forceful movements,
vibration, temperature extremes, and
awkward postures that arise from improper
work methods and improperly designed
workstations, tools, and equipment.

3. Ergonomic hazards can
cause painful and disabling
injuries till example
Musculoskeletal Disorder
(MSDs).

4. Types of ERGONOMIC HAZARD:
• Repetition
• Awkward Posture
• Forceful Motion
• Direct Pressure
• Vibration
• Extreme Temperature

5. Repetition
—Repetitive strain
injuries (RSIs).
Ergonomic injuries are
often caused by
repeating the same
motions over and over.

6. Awkward Posture
—awkward posture
often stresses the
spine and causes
muscle fatigue and
pain.

7. Forceful Motion
—Forceful Motion
Excessive effort needed to
do tasks such as pulling,
pounding, pushing, and
lifting.

8. Direct Pressure
—Direct pressure is on-
going contact between
a part of the body and
a hard edge of surface.

9. Vibration
—Vibration is transmitted into
your hands and arms when
using hand held / operated
tools and machinery. Excessive
exposure can affect the
nerves, blood vessels, muscles
and joints of the hand.

10. Extreme Temperature
—Temperature extremes
most directly affect
health by compromising
the body's ability to
regulate its internal
temperature.
