Button Batteries, Magnets, and Other Silent Home Hazards

Some of the most dangerous items in your home are tiny and easy to overlook. Button batteries and high-powered magnets can cause severe internal harm, fast.

The dangers you can't see coming

Not every hazard looks dangerous. Some of the scariest home dangers for toddlers are small, shiny, and easy to swallow, and the harm they cause can happen internally, silently, and quickly.

Button batteries and tiny high-powered magnets top this list. Because a swallowed one may not cause obvious immediate symptoms, parents can miss it until serious damage is done.

Why button batteries are so serious

A swallowed button battery, the little coin-shaped kind, can react with body tissue and cause severe internal burns in a couple of hours. They're in key fobs, remotes, greeting cards, toys, thermometers, and hearing aids.

Keep these devices' battery compartments secured (many require a tool or screw), store loose and spent batteries locked away, and treat any suspected swallowing as an emergency, seek medical care immediately and call poison control.

Magnets and other silent risks

Small, strong magnets (like those in some desk toys or magnetic building sets) are extremely dangerous if two or more are swallowed, because they can attract through the walls of the intestines and cause serious injury. Keep them entirely away from toddlers.

Other easy-to-miss hazards include laundry and dishwasher detergent pods (which look like candy), liquid nicotine, and small medicine caps. Store all of these locked, high, and out of sight.

Have a plan ready

Save the poison control number in your phone and post it somewhere visible. In an emergency, quick action matters enormously.

If you suspect your child swallowed a battery, magnet, or anything toxic, don't wait for symptoms, get emergency help right away and contact your pediatrician or poison control for guidance.
