A student is heating a piece of metal to test its properties. What would put the student in danger?

The student could be in danger if they do not use proper safety equipment, such as heat-resistant gloves and goggles, as the heated metal can cause severe burns or eye injuries. Additionally, if the student is working in a poorly ventilated area, toxic fumes may be released, posing a respiratory hazard. Improper handling of the hot metal could also lead to accidental drops, resulting in injuries or damage. Lastly, failure to follow safety protocols, such as keeping flammable materials away from the heat source, increases the risk of fire.
