When do firefighters go in first to car crashes?

Firefighters typically go in first to car crashes when there's a potential for fire, hazardous materials, or if there are trapped occupants needing immediate rescue. Their primary goal is to ensure the scene is safe and to provide medical assistance, often in coordination with paramedics. They assess the situation to determine the best approach for extricating victims and managing any risks, such as fuel leaks or electrical hazards.
