Over-exertion and Over-extension
is an overextension of our physical
capabilities-going a beyond what our bodies are able
to accomplish without
harmful results. This
superman performance is an
example. If it doesn't crush
him, he is going to hurt
Overexertion has many causes. The prime offender is working at a physically exhausting job for too long, in which case severe fatigue sets in.
Not only can this be harmful but the reduced awareness under such a condition can cause us to have accidents more readily.
Also, working too long in temperature extremes, can lead to colds, frostbite, heat exhaustion or heat stroke, depending upon whether the temperature is too cold or too hot.
Another form of overexertion can occur when attempting to lift or move heavy or awkward loads. Remember use your legs not your back. Back injuries hernias, sprains and strains can cause serious trouble.
The term "overexertion" is relative, meaning it often depends on the health condition of the worker.
What would not be overexertion for a worker in good condition might be too much for someone who is out of condition.
The second topic is overextension, which primarily deals with motion or balance.
How many times have we heard of a person trying to reach far to the side while working from a ladder, which results in a serious fall?
Attempting to jump from one level to another, or across an opening or a ditch, is overextension.
Running down stairs or taking two steps at a time is asking for an injury.
Reaching too far out from platforms or scaffolds or from members of a structure being erected is dangerous overextension.
Remember, overextension of what your body can safely do, from a health and well-being point of view, is overexertion.
In general, overextension involves trying to go beyond your own personal physical limits.
Be smart--don't expose yourself to either of these injuries.
