Are there any safety concerns with using aluminum sheets?

Aluminum sheets are generally safe to use, but there are a few considerations. They can be sharp when cut, so proper handling is important to avoid cuts. Aluminum is a good conductor of heat, so care should be taken to avoid burns when handling hot aluminum sheets. Additionally, inhalation of aluminum dust can be harmful, so it's important to work in a well-ventilated area or use a dust mask when cutting or grinding aluminum. In terms of long-term health, there's ongoing debate about the safety of aluminum exposure, but it's generally considered safe when used in accordance with proper safety measures.
