When using aluminum foil, it's crucial to follow safety regulations to prevent fires and injuries. Avoid using aluminum foil in conventional ovens as it can catch fire. Use it only in toaster ovens or microwaves if the manufacturer's instructions permit. Always ensure that the foil is not touching heating elements to prevent sparks or fires. Do not wrap aluminum foil around the outside of a turkey or other poultry when cooking, as this can cause uneven cooking and increase the risk of foodborne illness. Handle aluminum foil carefully to avoid sharp edges that could cut you. And finally, never leave cooking unattended when aluminum foil is in use to monitor for any potential safety hazards.
