Why should you not poke a knife into plugged in toaster to clear out the crumbs?

It is extremely dangerous to attempt to clean a toaster by poking a knife or any other metal object into it while it is plugged in. Toasters carry a high electrical current, and sticking a metal object inside can result in:

1. Electric Shock and Injury: When you insert a metal object into a live toaster, it can establish a connection to the electrical components within. Depending on the exact point of contact, you risk electrocution, severe burns, or other electrical injuries.

2. Short Circuit and Fire: Inserting a metal object can cause a short circuit, leading to overheating and even an electrical fire. This is extremely hazardous and could set your kitchen and house in flames.

3. Damage to the Toaster: Aside from the safety risks to yourself, sticking a knife into a toaster can damage the appliance’s heating elements and internal circuitry. This would mean you'd either need to repair or replace it.

Cleaning a toaster should always be done safely and by following recommended methods, such as unplugging and shaking it, using a non-metallic brush or compressed air for crumb removal, and checking the manufacturer's instructions. Poking a knife into a live toaster for cleaning not only risks your safety but can cause serious injury and property damage. It's essential to prioritize safety when dealing with electrical appliances.
