We have researched best practices for what CERTs should keep in their backpacks. See the list we recommend (PDF), including basic contents, personal items, first aid supplies and aids for light search and rescue.
We have arranged with Earth Shakes, a local disaster preparedness business, to provide these items in easy-to-purchase kits. We think you will find that buying these saves you money and time. Plus, Earth Shakes donates part of the proceeds to Central County Fire Department's CERT training program.
