Outlet Covers & Electrical Safety
Electrical outlets are one of the first things most parents childproof. Here’s what the CPSC recommends looking for in outlet protection, the different styles available, and how covers fit into broader electrical safety at home.
- KEY TAKEAWAYS
The CPSC lists outlet covers and plates as a basic childproofing step to help prevent electrical shock, and recommends choosing protectors that a child can’t easily remove and that are large enough not to be a separate choking hazard. For a more permanent solution, tamper-resistant receptacles — required in most new U.S. residential construction since 2008 — provide built-in protection that doesn’t depend on a cap being back in place.

What to Look For
Hard for a Toddler to Remove
Some cap-style covers can be pulled out by young children in seconds. Look for a style that needs a pinching, sliding, or two-handed motion that’s manageable for an adult but difficult for a toddler.
Large Enough to Avoid a Choking Hazard
The CPSC specifically recommends outlet protectors that are too large for a child to put in their mouth or swallow if one is removed.
Doesn't Require Reinserting Every Time
Box and sliding-plate covers stay in place once installed, unlike small caps that need to be taken out and put back every time the outlet is used.
Fits Your Specific Outlet
Standard duplex outlets, GFCI outlets, and outdoor/in-use outlets aren’t all the same shape. Choose a style rated for your outlet type so it seats securely instead of sitting loose.
What Outlet Covers Are For — and Where They Fall Short
Outlet covers and plates are meant to physically block a child’s access to the slots of an unused outlet. They’re a low-cost, easy-to-install layer of protection, which is why the CPSC includes them on its home childproofing checklist.
They’re not a complete solution on their own. Cap-style covers only protect an outlet while it’s unused, rely on an adult remembering to put them back after unplugging something, and — being small, removable pieces — can themselves become a choking hazard if a child works one loose. None of these products are a substitute for keeping an eye on young children around outlets and cords.
- SAFETY NOTE
Keep spare and removed outlet caps out of reach — they’re small enough to be a choking hazard. If your child seems able to remove a particular cover, switch to a sliding-plate or box-style cover instead of relying on that style.
Common Outlet Cover Types
| Type | How It Works | Things to Consider |
|---|---|---|
| Cap / Plug Covers | A small plastic disc plugs directly into the outlet’s open slots. | Has to be removed to use the outlet and reinserted afterward. Loose caps are small enough to be a choking hazard, and research on some cap styles has found young children can pull them out within seconds. |
| Sliding Plate Covers | Replaces the existing wall plate; a spring-loaded panel slides open only when a plug is inserted into both slots at once. | Stays on the wall permanently, so there’s no separate piece to lose or remember to put back. Installation needs to be done correctly for the slider to close reliably. |
| Box / Self-Closing Covers | A hinged box mounts over the entire outlet, enclosing cords and plugs that are already in use as well as any open slots. | Useful for outlets that usually have something plugged in, like a lamp or a monitor. Adds bulk, and box size needs to fit the mounting location. |
Electrical Safety Beyond Outlet Covers
Outlet covers address one part of electrical safety, but a few other habits matter too. Keep cords tucked out of reach so they can’t be chewed on or pulled, avoid overloading outlets or power strips, and unplug small appliances like curling irons or space heaters when they’re not in use.
If you’re renovating or replacing outlets, ask your electrician about tamper-resistant receptacles. These look identical to a standard outlet but have internal spring-loaded shutters that only open when both prongs of a plug are inserted at the same time, so a single object like a hairpin can’t make contact. The National Electrical Code has required them in most new residential construction — and in replacement outlets in areas accessible to young children — since 2008.
- SAFETY NOTE
Outlet covers and tamper-resistant receptacles reduce risk, but supervision still matters most for young children around electrical outlets, cords, and plugged-in devices.
