When working with aluminum, it's important to follow safety precautions. Always wear appropriate personal protective equipment (PPE) such as gloves, safety glasses, and a dust mask to prevent inhalation of aluminum dust. Ensure good ventilation to avoid the buildup of fumes. Use proper tools and equipment to handle aluminum, as it can become sharp and cause cuts. Be cautious of the heat generated during cutting or welding, as aluminum conducts heat quickly and can cause burns. Store aluminum in a dry place to prevent it from reacting with moisture, which can cause it to corrode. Lastly, be aware of the fire hazard associated with aluminum dust and take necessary fire prevention measures.
