    First, you will be required to carefully examine your paintball tanks. Perform an inspection on the tank to identify any cracks, leaks, scratches, nicks, gouges, burns or marks. If the tank is not safe to use, do not fill it with compressed air as this can be dangerous. If you do not know how to check the air tank, consider taking it to an expert who can help you decide if you should continue using it or buy a new one.
