What are the safety precautions when using aluminum foils?

When using aluminum foils, safety precautions include handling with dry hands to prevent electrical shocks, especially near electrical appliances. Avoid using foil with sharp or pointed objects to prevent punctures and potential ingestion of aluminum particles. Do not use aluminum foil in microwave ovens as it can cause sparks and fires. Keep foil away from children to prevent accidental ingestion. Always cut foil with scissors or a knife, not with your hands, to avoid cuts. Dispose of used foils properly to prevent environmental hazards.
