Make sure you have adult permission and supervision. Be familiar with safety equipment and know where it is located. Don't participate in outdoor water sports in bad weather. Discuss with your parents the safe areas of the house. Stay away from glass windows and doors.
Safe places are usually hallways, closets and bathrooms.
If you are outdoors and the weather turns bad, go straight home. If your home is not close, go to a safe place and call your parents. Watch for falling branches and trees. If there is lightning, don't stand under trees, try to go into a safe building. Stay indoors until the bad weather is over.
