The stove is particularly dangerous. Even if you don’t consider the immense heat, children could pull on a towel hanging on the handle and bonk themselves on the head. The best option is to buy a stove with a door lock. If that is not financially feasible, then you can purchase an aftermarket lock. While not highly practical, your safest move to prevent children from accidentally turning on the stove is to remove the control knobs when the stove is not in use and store them in a locked box. The more common solution is to purchase a set of stove knob safety covers. When you are cooking, try to use the back burners only. Never leave pot handles sticking out or forward. There are stove gates, too, that are similar to fireplace gates and serve the same purpose.
The dishwasher should also be locked if possible. The chief danger here is that children can ingest the detergent. If your child opens the dishwasher while it is running, however, there is a scalding danger as well. Children can also climb upon the door if it’s open, which will not only likely break the dishwasher but also create a falling hazard for the children.
Keep the microwave out of reach. Microwaves are heavy, and curious children can open the door, grab on, and perhaps pull the item off of the counter. They can also put anything you can imagine inside and start it. Avoid disaster and keep the microwave out of the “line of fire.” If possible, build a lockable enclosure for it. Other appliances can be equally or even more dangerous.
Other kitchen safety concerns
Coffee makers are small and light. Hot coffee scalds. Fondue pots, toaster ovens, rice cookers, countertop grills, and many other items get red hot, or nearly so, and can cause grievous injuries to adults let alone children. Many also contain glass with all the dangers that brings. Never keep these appliances out and only ever use them when you are present. Never leave them unattended even if you set the gates.
Your cutlery can turn instantly into a weapon. Children don’t know any better, so it’s entirely possible for them to cut someone else or themselves severely in seconds. Never keep a butcher block with knives on the counter. Always lock the silverware drawer. Never leave the dishwasher loaded. Always account for any cutlery you use. Children are not above hiding something shiny to play with later. Hide boxes of foil and waxed paper, too, because they have a sharp serrated edge that can be dangerous.
You may not consider it an appetizing place to play, but children can be fascinated with the garbage can. Keep it firmly secured and out-of-sight if at all possible. Most cans aren’t heavy enough to be injurious if tipped, but the contents could be. Aside from possible sharp objects in the trash, there might be muck that is rife with germs that can infect your child.
In short, your kitchen counter should have nothing on it, and everything that used to be on it should be under lock and key only to be taken out and used as needed and then locked away again.
