What specific actions and locations should be avoided to ensure safety when a thunderstorm occurs nearby?

To minimize risk during a thunderstorm, assess the threat early and take appropriate actions to avoid lightning. Stay away from windows and doors because they may contain metal components that can conduct electricity. Avoid using corded telephones unless in an emergency situation. Do not shower, bathe, wash dishes, or do laundry while a storm is active.

During a lightning thunderstorm, avoid sheltering in caves, under cliffs, or in open structures such as porches, bus stops, and gazebos. The safest action to take during a thunderstorm is to go inside immediately.
