Most people focus on personal, or family preparation to be ready in the event of an emergency. The Christian Emergency Network encourages advance preparation not just for yourself, but to help others. One step you should consider is volunteering in advance of an emergency to build a good networking group and learn key skills.
For example, if you volunteer as a firefighter you will learn how to keep firers under control, learn basic first aid and build relationships with others committed to helping others.
If you would like to improve your skills in cooking for a larger group, volunteer to serve in a soup kitchen, you will learn skills for cooking good, healthy food on a limited budget. Also, many Christian groups distribute food all year and by volunteering to help out you will learn the basics of logistics, and how to process supplies to a large number of people. During a disaster you just leverage those skills.
Your church group, or other organizations will have community wide ministry opportunities. As you volunteer to help out you will learn more skills and be in a stronger position to step in and help during an emergency. For example if you help out cleaning out public parks and trails, when a storm hits you are able to help clean up the mess.
When an emergency hits, those who have taken the time and made the commitment to learn skills and provide leadership will be able to stand strong and have an impact.
