Crush injuries occur when part of the body is trapped or compressed between heavy objects, machinery, vehicles, or other equipment. These incidents can cause serious damage to muscles, bones, nerves, and internal tissues, even when visible injuries appear minor. This first aid lesson covers recognizing the signs of crush injuries, calling for emergency medical assistance, assessing the injured person's condition, controlling bleeding when appropriate, and providing safe care while waiting for emergency responders. Employees will also learn the importance of avoiding unsafe rescue attempts, understanding the risk of crush syndrome, and following emergency response procedures to help prevent further injury.
