b. As you can see from figure 1-6, when good body mechanics is practiced, the
center of gravity is low. Note, too, that the line of gravity crosses the center of gravity
and the base of support. Consider the frontal pose (right-hand portion, figure 1-6).
Note that the base of support is wide, since the feet are spread apart.
c. The body is most stable when the line of gravity bisects the base of support.
You can protect your back while carrying heavy objects by maintaining good posture
and holding your load close to the body (figure 1-7). When the load is held close to the
body, the line of gravity will bisect the base of support. Did you notice that one foot is
placed slightly in front of the other? This provides the advantage of added front-to-back
Figure 1-7. Carry the load close to your body. Keep feet apart, with one foot slightly in
front of the other.
d. Figure 1-8 is an example of what not to do! You are inviting back injury, if
you hold the load away from your body. The line of gravity will not bisect the base of
support. The consequence of this technique is suffering fatigue, strain, and possible
injury. This will not only mean personal discomfort, but a heavier workload for
colleagues who might have to fill in for you if you are not able to work because of an
injury. Do not allow failure to practice common sense body mechanics place you out of
commission. Take a moment to think before acting in order to plan your movements for
maximum ease and efficiency and minimum strain.
