MATERIAL HANDLING:- MOTION CONTROL
Body motion injuries are many and varied. Among them, sprains and strains are most common. Sprains are simply weakening of a joint and related muscle, caused by sudden or excessive exertion. Strains usually occur when muscles are stretched beyond their proper limits.
How does it happen? For example you step off the last step of a stairway in the dark not realizing it is there. Your muscles are not prepared to take the weight and maintain your balance as normal. You start to lose your balance and your body automatically reacts to keep you from falling, causing an overreaction on your muscles which are not prepared to take it. The result is a torn or strained muscle. Other examples,
A pipe fitter pulled his back while using a wrench which slipped.
A fitter slipped on a shovel, and while attempting to regain balance he injured his back.
While changing the wheel of his car, a technician sprained his wrist, because the spanner slipped.
In sports it is very common.
These could have been avoided by using safer procedures and little more extra caution. Use proper tools for the job. Make sure that your work platforms are clean, tidy and free of unwanted things — no tripping hazards. Careful while climbing stairs. Enough lighting in the working area. Careful of wet, oily and greasy surfaces. Follow proper lifting procedures, etc.
Only you can judge how much you should move, what walking to do and so forth. Only you know of physical conditions that may prevent you from normal exertions.
