The Huntsville Cave Rescue Unit (HCRU) will be hosting an orientation to cave rescue techniques this summer. "Technical Rescue Personnel: Cave Rescue Awareness, Operations, and Technician" is an NFPA accredited class with cert and non-cert options available through the Alabama Fire College.
If you haven't taken a cave rescue class yet, taking one will make you a valuable, skilled, and safer caver. If you are interested in joining the HCRU, it is not necessary that you take this class but it will help make you a competent rescuer.
More details and registration can be found on their website:
