Fatal Projectile Injury from an Unsecured Metal Rim During Tire Inflation: A Case Report and Safety Insights

Tire service stations present serious hazards, especially during high-pressure air inflation. While tire bursts are known to cause fatal injuries, metal rim ejections due to improper disk locking are underreported. This case highlights the risks associated with unsecured metal disks and underscores the need for safety measures in the form of a daily check-up of the machine before starting the work. Here a 40-year-old mechanic sustained fatal injuries when a loosely fitted metal rim was propelled by high tire pressure during air inflation. With the remolding machine door left open, rising pressure dislodged the poorly locked disk, sending the rim six feet, striking his head and face. The injuries matched the distorted rim found at the scene. He was hospitalized, unconscious, and died five hours later. This case highlights the dangers of improper locking during tire inflation, emphasizing the need for strict safety protocols. Secure disk fittings, protective barriers, and adherence to guidelines are crucial. Raising awareness, proper training, and enforcing safety regulations can help prevent fatal injuries in tire service stations.
