You're a careful parent who steers children away from things that could harm them. But hidden threats lurk in every house—sometimes where you least expect them. For safety's sake, look through your home often. Keep an eye out for not-so-obvious hazards. Here are five of them:

It is common for a home's water heater to be set above 120°F (48.8°C). This can cause a scald burn to a child in seconds. Scalding hot tap water causes thousands of injuries and more than 30 deaths a year. A lot of victims are young kids.

Solution: Set your hot water heater to no higher than 120° F (48.8°C). And check the temperature of your tap water to be sure it's safe.

Each year, thousands of young kids are badly injured—and some die—when large TVs and heavy furniture tip over on them. Often, the victims were climbing on it, or pulling themselves up on it, or falling against unstable furniture.

Solution: Double-check the stability of large furniture. Anchor stoves, TVs, bookcases, shelves, or dressers to the wall. Get rid of items that may tempt kids to climb.

Hundreds of children have strangled to death after getting tangled up in cords or chains on window blinds. Window coverings sold before 2001 pose the most danger.

Solution: Secure the cords of older window coverings so children can't reach them. Or replace them with safer, cordless blinds. Move cribs, beds, and other furniture away from windows. Use only cordless window coverings in children's sleep and play areas.

Most poisonings happen at home. Many poisons are found in the garage, outside yard, kitchen, bedroom, or bathroom. They include pesticides, automotive products, weed killers, and household cleaning and disinfectant products.

Solution: Store harmful chemicals in their original, labeled containers—and keep them safely out of reach. Consider locked cabinets for storage. Never leave chemicals unattended when you are using them. Teach your family to never touch or put anything in their mouths unless they know what it is,

Backyard trampolines send tens of thousands of people younger than 20 to doctors and emergency rooms each year. Injuries range from sprains, broken bones, and cuts—to neck and spinal cord injuries, paralysis, and even death.

Solution: Don't use home trampolines without constant adult supervision. In gym classes or competitive sports, use a trampoline only with strict adult guidance and supervision.
