Safety Tips for Irrigation Equipment Field crop irrigation equipment today is often large and complex, which requires a high level of management and operating skill on the part of the producer. Modern irrigation systems also introduce a number of safety concerns unlike those experienced with other field equipment. It is vital that irrigators know and follow proper safety precautions to avoid potentially deadly electrical accidents when operating and handling modern irrigation systems. Aluminum irrigation pipe, while lightweight and easy to handle, is an excellent conductor of electricity. It is best to avoid moving irrigation pipe and equipment on windy days, as a sudden gust could lift pipes into overhead power lines. This power line contact could prove fatal to a person holding the pipe. Take some time to survey your surroundings before moving equipment. Look up and around you; note any power lines that could be close enough to come into contact with equipment – and stay away.

• Store unused irrigation pipes far away from power lines or electrical equipment. Keep pipes horizontal to the ground rather than vertical to minimize the risk of contact with power lines. • Position the water jet streams so that there is no chance of them spraying onto power lines – if this happens, the entire system could become energized, creating a danger for anyone nearby. • Stay away from all irrigation equipment during any lightning activity. Install lightning arrestors to protect your equipment from damage caused by lightning strikes. • If fuses continually blow or circuit breakers repeatedly trip, have a professional check the wiring. This could indicate a potential electrical hazard. • Assess the equipment for defective components that may energize devices that are not normally energized (i.e. the equipment enclosure, etc.). • Always shut off and lock the master electrical control switch before servicing the machine. • If you are testing equipment, protect yourself by wearing safety glasses and an arc-rated face shield, wear clothing that will not ignite in an arc-flash scenario (no synthetic clothing, synthetics can melt and stick to the skin increasing the level of injury). Fire resistant clothing is highly recommended.

Take some time to survey your surroundings before moving equipment.

In addition, troubleshooting problems with 480 volt equipment carries an increased electrical hazard. A high percentage of electrical arc flash injuries and fatalities are associated with 480 voltage equipment and components.

To ensure safe operation of irrigation equipment please remember the following tips: • Make sure that irrigation system wiring is properly grounded. Before the start of each irrigation season, have a qualified electrician check the pump and wiring.

• Insulating gloves should be worn to protect from electrocution as well as the heat produced by the arc-flash. Please contact Inland Power at (509) 747-7151 to get answers to any additional safety questions you may have.

SAFETY CORNER Help Inland Power Battle Copper Theft Soaring metal prices have been blamed for an increase in thefts of copper and aluminum, primary components of electric distribution lines. Recent thefts of copper wire and equipment from electric utilities have been responsible for outages, additional maintenance and expenses, diminished service reliability, and, in some cases, serious injury or death. Inland Power urges you to follow the following guidelines to guard against electrical dangers and help prevent copper theft. • Never enter or touch equipment inside a substation; stay away from power lines and anything touching a power line. • If you notice anything unusual with electric facilities, such as an open substation gate, open equipment, or hanging wire, contact Inland Power immediately at (800) 747-7151. • If you see anyone around electric substations or electric facilities other than Inland Power personnel or contractors, call the local police/ sheriff as soon as possible.

Together we can stop copper theft!
