If you find yourself caught in a strainer, the best thing to do is remain calm and try to assess the situation. If you are able to reach the edge of the strainer, you may be able to pull yourself out. Otherwise, try to wedge your body or an object into the strainer in order to create some space. Once you have created some space, attempt to swim or wiggle your way out of the strainer. If all else fails, call for help!
