When severe weather strikes quickly, evacuation may be difficult. In these situations, many experts say the best place to head is a safe room. A safe room is a freestanding structure with walls and roof built of materials capable of withstanding the impact of falling and flying debris. They're also the logical place to store your Storm Kit and other supplies. Safe rooms are designed to be independent of the house structure and are securely bolted to a concrete basement floor, ground-level slab or outside pad. They can be made from reinforced poured concrete, concrete block, welded steel or multiple layers of wood, steel and fiberglass.
