Using a metal fork to retrieve toast from a toaster can be dangerous and might cause electrification if the fork comes into contact with the live electrical components inside the toaster. Toasters are small appliances designed to toast bread by passing an electric current through the heating elements.
The body of a toaster is typically made of metal, and the toaster's internal components are connected to the electrical supply. If you insert a metal fork into the toaster while it's plugged in and accidentally touch the live parts, you could potentially receive an electric shock.
On the other hand, a portable oven (such as a toaster oven) usually operates differently. Most toaster ovens have heating elements on the top and/or bottom, and they usually don't have exposed electrical components accessible from the outside. This design reduces the risk of direct electrical contact with the user when retrieving food with a metal fork.
However, it's important to remember that using metal utensils in any electrical appliance can be risky. It's always best to use non-metallic utensils or, if you need to use metal utensils, make sure the appliance is unplugged and completely cool to avoid any potential hazards. Additionally, always follow the manufacturer's guidelines and safety instructions for any electrical appliances you use.
