What should you know about tetanus and metal?

Tetanus bacteria can enter through a break in the skin. A nail, wire, tool, or other metal object can create a deep or narrow wound that is difficult to clean. Rust is not the cause, although a rusty object may be dirty and capable of injuring tissue. The relevant details include how deep the wound is, whether soil or debris entered it, and when your last tetanus-containing vaccine was given.

Wash your hands, rinse the wound under clean running water, and remove visible dirt gently. Do not probe a deep puncture or pour harsh chemicals into it. Cover the area with a clean dressing. Arrange medical advice promptly if the wound is deep, heavily contaminated, caused by an object that remains embedded, or difficult to clean. A clinician can assess the wound and check whether a booster or other preventive treatment is appropriate.

Seek urgent medical care for increasing jaw stiffness, trouble swallowing, painful muscle tightening, breathing difficulty, spreading redness, pus, fever, or severe pain. Also seek prompt help when a metal object has punctured the foot, hand, face, or near a joint, or when part of it may still be in the wound.

Ask whether the wound needs professional cleaning, whether your immunization history is sufficient for this injury, and which changes should prompt a return visit.
