I live on the West Coast in earthquake country. I want to put together an earthquake kit filled with canned goods and water. I want to store these items in a shed in the back yard. I live in Riverside and it gets very hot in the summer. Is there a problem storing canned food and bottled water in temperatures up to 115 degrees? It would be a metal shed so the inside of the shed would probably be hotter than the outside. I have young children so I don’t want to risk harming them with canned foods that spoiled due to heat. Thanks.
