Outside Equipment
Another area of concern beyond electrocution while operating equipment results from coming into contact with overhead electrical lines while outside of the equipment when producers are on foot. Equipment and tools that have the greatest risk for coming in contact include: ladders, irrigation pipes and portable grain augers. Movement of these items should not be done in the dark, and, if possible, should not be done alone, as the potential for losing control is higher.
TABLE 1. EFFECT OF ELECTRIC CURRENT ON HUMANS.
Risk | Milliampere | Effects |
---|
Safe | Less than 1. | No sensation, not felt. |
Safe | 1 to 8 | Shock sensation; not painful' can let go at will. |
Unsafe | 8 to 15 | Painful shock' can let go at will. |
Unsafe | 15 to 20 | Painful shock; loss of adjacent muscle control; cannot let go. |
Unsafe | 20 to 50 | Painful, severe muscle contractions; difficulty breathing. |
Unsafe | 50 to 100 | Possible ventricular fibrillation. |
Unsafe | 100 to 200 | Certain ventricular fibrillation. |
Unsafe | More than 200 | Severe burns; severe muscular contractions; chest muscles clamp heart and stop it for the duration of shock. |
One milliampere (mA) is 1/1000th of an ampere (current). Ventricular fibrillation is a breakdown of the pumping coordination of hear muscles that will not correct itself. This information applies to adults. Weaker currents could be fatal to children. Information taken from the National Safety Council. Source: Texas Cooperative Extension. |
Reducing Risk
As an agricultural producer, you can reduce your risk of electrocution by following these recommendations.
- Be aware of the location of overhead power lines on your farm and choose a route for your equipment that avoids them.
- Never touch a power line.
- Avoid using ladders, portable augers or irrigation equipment around power lines.
- Maintain 10 feet of clearance space between the power lines and your equipment. Contact your power company to determine the height of power lines on your farm.
- Review safety measures with all individuals working on your farm, whether full-time, part-time, voluntary or family.
- Remember that even nonmetallic objects, such as tree limbs, ropes, and straw, can conduct electricity.
In Summary
Don’t have an unfortunate harvest season and become a farm accident statistic! Assessing your electrocution hazards around your farm and fields and developing a plan may save a life this year.
