What do you do if the jumper cables smoke and catch fire?

If the jumper cables smoke and catch fire, immediately disconnect them from both vehicles to prevent further damage or injury. Use a fire extinguisher if available, targeting the base of the flames, or smother the fire with a thick cloth or other non-flammable material. Ensure you keep a safe distance and avoid using water, as it can spread the flames or cause electrical hazards. Once the fire is out, assess the situation and seek professional assistance if needed.
