Being ready for a disaster entails many things. A HAM radio operator being ready for a disaster involves even more. Depending on the role that you wish to play as a volunteer communicator, after securing your family, there a number of things to do to be prepared to respond at the drop of a hat.

First steps first! Secure your family.  (My family is secure, take me to the next step)

Securing your family is priority number one. The steps for this are identical for everyone, not just HAMS.

Get a kit, Make a plan, Be Informed.

Food supplies need to be sufficient to feed each person in your family and if you have the space and resources, a little extra for a friend in need. Each food group needs consideration and vitamins and medicine as well. Canned good will last well beyond the date on the can but rotating stock for better quality is a good idea. Canned citrus ought to be rotated out due to the acid in the fruit.

It may be better to buy the food now and worry about storage afterwards. The main idea is just get started. You can tweak the menu and storage as you go. Consider storing the food on the ground floor and against an outside wall or maybe a heated outside workshop. If you have to dig it out, much better to make a hole in the wall for access than to take days and risk injury to dig it out from the middle of the house.

Water needs are significant. Drinking, cooking, bathing, etc. for one even one day requires a substantial amount of storage space. Depending on where you live and the type of disaster encountered, you will have different options.
