Electrical Safety After Flooding: What Not to Do

Electricity and floodwater are a dangerous combination, and the danger is not always visible. A floor that looks safe can hide a live risk, an appliance that looks dry can still hold water inside, and a switch that looks ordinary can be the last thing you should touch. After a flood, the electrical rules are simple, strict, and worth knowing before you need them, because the moment to learn them is not the moment you are standing in water.

This guide covers what not to do around water and electrics, and the safety steps that come first. The emergency water extraction service page covers the service, and homes in Metairie and Bossier City face the same electrical questions after a flood as homes anywhere else in the state.

Why floodwater and electricity are dangerous together

Water conducts electricity, and floodwater in a home can reach outlets, switches, appliances, and wiring that are normally well above the floor. A live circuit in contact with standing water can energise the water itself, and the danger is not limited to the point of contact: the whole wet area can be at risk, and the risk is not visible to the eye.

Floodwater also damages electrical systems in ways that show up later. Wiring, junction boxes, and appliances that have been in water can corrode, short, or fail weeks after the flood, even when they seem to work at first. That delayed risk is one more reason flood-affected electrics need a professional assessment rather than a quick test at home.

The rule that follows from all of this is simple: treat every electrical item in or near floodwater as live until a professional has judged it safe. Do not test that assumption yourself, and do not let anyone else test it either.

What not to do: the strict rules

Do not handle any electrical item in or near standing water. Do not touch outlets, switches, or appliances that have been in water, and do not switch anything on to see whether it still works. Do not use a household vacuum on standing water, and do not use any electrical equipment in a flooded room.

Do not reach for a power shutoff through standing water, and do not feel for a switch in the dark. If you can reach the main shutoff from a dry place and you are certain it is safe to do so, that is one option, but if there is any doubt, leave the power alone. Never wade into standing water to reach a shutoff.

Do not enter a flooded building if you suspect the power is still on, and do not enter a room where the ceiling looks soft or sagging, since water and electrics can both be hidden in the structure above. If the home looks unstable, or if the water is still rising, stay out entirely.

What to do instead: the safe steps

Stay out of the water, and keep everyone, including pets, out of the flooded area. If you can reach the main power shutoff from a dry place and you are certain it is safe to do so, that is one option, but it is the only electrical action to consider, and only from a dry place. If you are unsure, leave the power as it is and call for help.

Call a professional and describe what you see: where the water is, whether it has reached outlets or appliances, and whether the power is still on. That description helps the person on the phone decide the next step, and it is easier to give clearly in the moment than to reconstruct later.

Our standing water removal page describes the standing-water stage in general terms. The same principles apply here: safety first, then assessment, and no electrical action until the space has been judged safe.

Outdoor electrics deserve their own warning after a flood, because they are easy to forget when the focus is on the rooms inside. Do not touch outdoor outlets, switches, or equipment that has been in water, do not switch on garden lighting or pumps that were flooded, and stay away from downed power lines and from any electrical equipment in or near floodwater outside. If you smell gas outside, leave the area and call for help from a safe place, and do not light anything until the property has been assessed.

Appliances and equipment after a flood

Appliances that have been in floodwater should not be switched on, and they should be handled as part of the professional assessment rather than tested at home. An item that looks dry on the outside can still hold water inside, and switching it on can cause damage or injury. That applies to televisions, computers, kitchen appliances, and anything else that was in the water.

Do not try to dry electrical equipment yourself, and do not open it to look inside. Leave it where it is, take photos if it is safe to do so, and keep a list of affected items. The assessment will decide what happens to each item, and that decision should rest on a professional check rather than a guess.

Homes in Kenner and Covington face the same appliance questions after a flood, and the same rule applies: if it has been in water, do not switch it on. Availability is confirmed on the call. Call (877) 624-0105 to talk through what you found.

After the flood: getting electrics checked

After a flood, the electrical system itself needs to be checked before the power is restored and the home is used normally. That check belongs to a qualified professional, and it covers the wiring, the outlets, the switches, and the appliances that were in the water. Do not restore power yourself, and do not assume the system is safe because it looks dry.

Keep a record of the event: the date, the time you found the water, photos of the affected areas and the electrical items involved, and notes about the source if you know it. That record helps a professional judge the space and is useful if questions about the loss come up later. Photos taken before anything is moved are the most useful of all.

Finally, remember the habit that prevents the next electrical risk: know where your main power shutoff is before you need it, and make sure everyone in the household knows where it is too. Knowing its location in advance, and knowing that it should only be reached from a dry place, is what makes the first minutes of a flood safer.

Know where your main power shutoff is before you need it, and make sure everyone in the household knows where it is too. Knowing its location in advance, and knowing that it should only be reached from a dry place, is what makes the first minutes of a flood safer. A household that knows where the shutoff is, and that knows never to wade into standing water to reach it, is a household that stays safe when the water arrives.

If you rent, tell your landlord or property manager about the flood and the electrics as soon as it is safe to do so, in writing as well as by phone, with photos of what was affected. The building's electrical system belongs to the landlord, and the check of it belongs to a qualified professional, so the report should go to both. Keep a copy of everything you send and receive, since that record matters if questions come up later.

Questions About Electrical Safety After Flooding: What Not to Do

Is it safe to touch a light switch after a flood?

No, not if the switch or the area around it has been in water, or if you are standing in or near standing water. Do not touch outlets, switches, or appliances that have been in water. If you can reach the main power shutoff from a dry place and you are certain it is safe to do so, that is one option, but if there is any doubt, leave the power alone.

Can I switch on an appliance that was in floodwater?

No. An appliance that has been in floodwater should not be switched on, and it should be handled as part of the professional assessment rather than tested at home. An item that looks dry on the outside can still hold water inside, and switching it on can cause damage or injury.

Should I turn off the power if my house floods?

Only if you can reach the main power shutoff from a dry place and you are certain it is safe to do so. Never wade into standing water to reach a shutoff, and never feel for a switch in the dark. If there is any doubt, leave the power alone and call a professional.

Why is floodwater dangerous around electricity?

Water conducts electricity, and floodwater can reach outlets, switches, appliances, and wiring that are normally well above the floor. A live circuit in contact with standing water can energise the water itself, and the danger is not limited to the point of contact. The risk is not visible, so every electrical item in or near floodwater should be treated as live.

Your Next Step

If this guide matches what you found at home, the next step is a visit — not a guess. Call and describe what you found, and the visit is arranged from what you describe. The Emergency Water Extraction page explains what that service covers, and the water removal page explains what that service covers when water has spread to more than one room.

Do not enter flooded rooms while you wait, and if water is leaking, turn off the shut-off valve for that fixture where you can reach it safely from dry ground.

Keep the guides on this site bookmarked: the first guide, the signs guide, and the preparation guide cover the checks worth repeating — after moving in, and after bringing used fixtures home.

Water extraction help is available across Louisiana. See water extraction in Belle Chasse, LA for one local example, or find your town on the service areas page.
