Your life is more important and that is the point behind most prep articles.
They want you to focus on life saving or life extending practices.
A fire is usually within a specific area. Outside that area there will be no damage so food, shelter, and life as we know it continues as normal.

If you have all that time to gather something that you won't be needing then use the time he gave you to gather something of importance like the family photo album and other keepsakes which he says will be destroyed.
