What is the best way to check for gas fumes after feeling a PWC?

To check for gas fumes after feeling a Personal Watercraft (PWC), first ensure you are in a well-ventilated area. Use your nose to detect any strong gasoline odors, and visually inspect for any signs of leaks or spills around the fuel tank and lines. If you suspect gas fumes, avoid using any open flames or sparks, and consider using a gas detector for a more accurate assessment. If fumes are present, take immediate action to ventilate the area and address any leaks.
