What is the first aid step if a large piece of metal is impaled through a leg?

Stabilizing the piece of metal in place with a bulky dressing is the appropriate first aid step when dealing with an impaled object, such as a large piece of metal, through a leg. The reason for this is that removing the object can cause further injury, increase bleeding, and potentially lead to the introduction of bacteria into the wound, resulting in an infection. By stabilizing the object, you help minimize movement, which can prevent additional damage to surrounding tissues and blood vessels. Using a bulky dressing can also support the impaled object and provide some protection until medical professionals can take over for further assessment and treatment. This approach helps maintain the integrity of the injury site while ensuring the patient's safety during transport to a medical facility.
