Reaching over a hot stovetop can cause burns from the heat source itself, splatters of hot liquids or grease, and clothing catching fire.
Reaching across a hot stovetop presents several dangers. First, the radiant heat from the burners or elements can cause burns, even without direct contact. The closer you get, the more intense the heat becomes. Second, hot liquids or grease can splatter from pots and pans, causing painful burns. This is especially true when stirring or adding ingredients. Finally, loose clothing, such as sleeves or aprons, can easily catch fire if they come into contact with a flame or hot surface. Synthetic fabrics are particularly flammable and can melt onto the skin, causing severe burns. The combination of heat, liquids, and potential for clothing ignition makes reaching over a hot stovetop a significant safety hazard in the kitchen.
Always use back burners whenever possible, and turn pot handles inward to prevent accidental bumps and spills. This minimizes the need to reach over hot surfaces and reduces the risk of accidents.
