Electrical Safety Around Water

Water makes electrical problems worse. Farm work puts hoses, tanks, wet floors, rain and flooded yards alongside cords and equipment. This guide covers the principles.

Why is water such a problem?

Water helps electricity travel, and wet skin, wet floors and wet equipment offer easy paths through the body. A tool with a small fault may be harmless in a dry shop and dangerous in a wet barn. Moisture also corrodes parts and damages insulation over time.

For these reasons, safety guidance stresses protecting circuits and equipment in damp locations.

Even small amounts of moisture on a plug or tool handle can change how electricity behaves, so the safest approach is to keep them dry.

• Wet skin lets electricity pass more easily
• Wet floors and tools provide easy paths
• Moisture corrodes parts and damages insulation
• Small faults become serious in damp rooms

Where do the problems cluster on a farm?

Wash bays, milk houses, livestock waterers, tank heaters, pumps, irrigation sites, hose areas and outdoor outlets are the usual suspects. Flooded basements, barns and yards after storms are another.

Walk your property and note every place where water and power are within reach of each other.

Ask workers which places make them uneasy. They often know where tingles and trips have happened.

What protective measures should you ask about?

Ground-fault protection is designed to help protect people in damp and wet locations. Equipment and fittings built for wet locations are another measure. A licensed electrician can assess each area and suggest options. The guide on GFCI protection on farms explains the idea.

Rules differ by location and age of installation, so ask your code office about what applies to your buildings.

• Walk the farm and mark every wet place with an outlet or cord
• Rank those places by how often people use them
• Ask an electrician about protection in the top few
• Revisit the list after floods and renovations

What habits help?

Keep cords, plugs and power strips off wet floors and out of puddles. Dry your hands before handling plugs and switches. Do not use damaged cords or tools near water. Keep electrical gear on dry surfaces and out of spray.

Do not use pressure washers or hoses around outlets, panels, motors and light fixtures. Shut off power before cleaning equipment when practical and as the manual advises.

Remind everyone to dry off and stay out of puddles when connecting equipment.

• Dry hands before touching plugs
• Keep cords off wet floors
• Shut off power before washing equipment
• Report tingles and trips right away

What about livestock waterers and tank heaters?

A faulty heater or wire can energize a tank. Animals may avoid drinking, show nervous behavior near a tank, or tingle when touching metal. These are signs to unplug equipment and call an electrician and your veterinarian.

Use equipment made for the purpose and follow the maker's instructions. Keep cords where animals cannot chew them.

If animals are reluctant to drink, treat it as a possible electrical problem and have it checked right away.

• Animals that avoid a tank may be feeling a tingle
• Unplug the heater and call an electrician
• Tell your veterinarian what you saw
• Replace heaters not made for the purpose

What should you do after a flood?

Do not enter flooded areas with live power. Do not touch electrical equipment that has been underwater. Have the electric utility and a licensed electrician check wiring, outlets, panels and motors before power is restored.

Water damage can hide inside walls and equipment for weeks. Equipment that has been submerged may need replacement. Check with the maker and your insurance carrier.

Keep a list of equipment that has been wet, and have each item tested before it is used again.

• Stay out of flooded buildings until power is confirmed off
• Call the utility and an electrician before restoring power
• Replace or have tested any equipment that was submerged
• Ask your insurance carrier about documentation

What if someone is shocked near water?

Call 911. Do not touch a person who may still be in contact with an electrical source and do not step into water that may be energized. Wait for responders and the utility.

Recognized first aid training teaches what to do while waiting, and it is best learned in person from a provider such as the American Red Cross.

• Call 911 first
• Do not step into water that may be energized
• Wait for responders and the utility
• Take a hands-on first aid course
