To find the right storm shelter for your home then you should always make sure that the company is approved by the NSSA. A company that's qualified to be a member of the NSSA is a company that will provide you with a safe storm shelter. Another thing you should consider would be a safety mechanism that allows the door to be opened from the outside or the inside. You should also find out what the company uses to anchor the shelter, and why they use that particular anchor.
