When using aluminum foil in the kitchen, it's important to handle it carefully to avoid sharp edges that can cause cuts. Avoid using it in direct contact with an open flame as it can melt and release toxic fumes. Do not use aluminum foil with non-stick cookware as it can damage the surface. Keep it away from high heat sources like broilers and never use it to line baking sheets as it can catch fire. Always ensure that any food wrapped in aluminum foil is sealed properly to prevent the foil from coming into contact with heat sources directly.
