PRINCIPLES OF GOOD BODY MECHANICS
a. Maintain a Stable Center of Gravity.
(1)
Keep your center of gravity low.
(2)
Keep your back straight.
(3)
Bend at the knees and hips.
b. Maintain a Wide Base of Support. This will provide you with maximum
stability while lifting.
(1)
Keep your feet apart.
(2)
Place one foot slightly ahead of the other.
(3)
Flex your knees to absorb jolts.
(4)
Turn with your feet.
c. Maintain the Line of Gravity. The line should pass vertically through the
base of support.
(1)
Keep your back straight.
(2)
Keep the object being lifted close to your body.
