The free Guidelines for Sump Rescue manual collects the best practices for managing a sump rescue incident. This is an unofficial document and not approved by any agency or governing body. It collects the lessons learned from over 100 years of rescuing people from overhead environments who are trapped by water. Contributions have come from experienced personnel from around the world. Some elements of this manual may be useful to personnel conducting rescues from flooded mines, overturned ships, etc, but please notes that those environments have their own special considerations.
