* Insulation: Wood and plastic are excellent insulators. This means they do not conduct electricity well. When you use an electric iron, the heating element inside gets very hot. Having a wooden or plastic handle prevents the heat from transferring to your hand, ensuring you don't get burned.
* Heat resistance: Both wood and plastic can withstand the heat generated by the iron's heating element without melting or becoming brittle. This makes them suitable for holding the iron even when it's hot.
* Comfort and grip: Wood and plastic offer a good grip, providing a comfortable and secure hold even when the iron is hot and sweaty.
* Durability: Both materials are relatively durable and can withstand the wear and tear of regular use.
Metal handles, on the other hand, would be dangerous for the following reasons:
* Conductivity: Metal conducts heat very well. If the iron's handle were made of metal, the heat from the heating element would transfer quickly to your hand, leading to severe burns.
* Shock hazard: Metal can conduct electricity. If the iron's wiring is faulty, a metal handle could become live, posing a serious electrical shock hazard.
Therefore, using wooden or plastic handles for electric irons is crucial for both safety and usability.
