Center Pivot Safety

A center pivot is a large machine with moving parts, electrical systems and water. This guide covers general safety principles and sends you to manuals and official sources.

What makes a center pivot hazardous?

A center pivot combines electrical equipment, long moving spans, wheels on wet ground, and pressurized water. Hazards include electric shock, being struck or run over, falls, and slips on wet or muddy ground.

Because pivots run on their own and cover large areas, people may not notice the machine until it is close. Treat every pivot as live and moving unless it has been properly shut down and secured.

The size of the machine can hide the risk. Because it moves slowly, people sometimes assume they can step away or step back in time, when this is not true.

• Electrical shock.
• Struck or run over by moving spans.
• Slips and falls on wet ground.

What does the manufacturer's manual say?

The owner's manual explains the correct start-up, shut-down and service procedures for your pivot. Safety rules, lockout steps and inspection checklists come from the manufacturer, so read the manual and keep it accessible.

Do not rely on memory or habit for service work. If a manual is missing, contact the dealer or manufacturer for a copy. This article does not give technical procedures.

Training sessions offered by dealers, cooperatives and extension offices give hands-on instruction. Ask what is available before the season starts.

• Keep the manual where workers can find it.
• Follow manufacturer shut-down procedures.
• Ask the dealer for training.

How should you handle electrical safety?

Only qualified people should work on electrical panels, motors, control boxes and wiring. Water and power together can cause serious harm. If you see damaged wiring, sparks or smoke, keep away and contact a qualified electrician.

Overhead power lines near pivots are a special hazard when moving or setting up equipment. Keep a safe distance as directed by your utility, and ask the utility about requirements before moving large equipment.

Lightning is another concern. A pivot is a tall metal structure in an open field, so keep clear during storms and follow National Weather Service guidance.

• Use qualified electricians.
• Stay clear of damaged wiring.
• Ask your utility about overhead lines.

What about working around moving spans?

Spans and towers can move without warning if the system is not properly shut down. Do not walk or work under or near a pivot unless it is locked out and secured as the manufacturer directs. Never ride or climb on moving equipment.

Tell others where you are working. A person on the ground near a tower can be hard to see, especially in crops. Use a check-in system, and do not work alone.

• Lock out before service.
• Never climb on moving equipment.
• Do not work alone.

What are the water hazards?

Pivots draw from wells, ponds, canals or pipelines, each with its own hazards. Wet ground and ruts around wheel tracks can hold water and become slippery or unstable. Leaks and spray can create ice in cold weather.

If the water source is a pond or canal, review the safety advice for those structures. Keep children away from the pivot and the water source.

After any problem with the water source, such as a flood or a pump failure, have the system checked before restarting it.

• Check water sources for hazards.
• Watch for ruts and slick spots.
• Keep children away.

What should you do in an emergency?

Call 911 for any injury, electrical contact or entrapment. Do not touch a person who may be in contact with live equipment. This article does not teach rescue or first aid steps; trained responders must handle these situations.

Seek hands-on first aid and CPR training from recognized providers such as the American Red Cross. Share the location of each pivot with local dispatch if they offer a way to do so.

Afterward, review what happened and what could be changed, such as better labels, a locked panel or clearer instructions for seasonal workers.

How can you plan maintenance and inspections?

Create a schedule for inspections before the season, during it and after storms. Record problems and repairs. Involve a dealer or qualified technician for major work.

Brief all workers, including seasonal help, on the hazards and procedures. Provide training in a language they understand. For employer duties, see OSHA's agriculture page, and for youth work, confirm rules with the U.S. Department of Labor.
