TO PREVENT ACCIDENTS
The majority of accidents and injuries which occur in industry, on the farm, at home or on the
road, are caused by the failure of some individual to follow simple and fundamental safety rules
or precautions. For this reason MOST ACCIDENTS CAN BE PREVENTED by recognizing the
real cause and taking the necessary precautions, before the accident occurs.
Regardless of the care used in design and construction of any type of equipment, there may be
conditions that cannot be completely safeguarded against, without interfering with reasonable
accessibility and efficient operation.
