A CMC Exclusive. Rick Cearley, a retired senior helicopter pilot for the Los Angeles County Fire Department and inventor of the LSP Cinch Rescue Collar, identified the need for a product to rapidly secure a victim under difficult conditions, such as swiftwater rescues. Despite its simple appearance, this Cearley original design has features developed through years of field use by Los Angeles-area firefighters and rescuers. Why You Need a Rescue Strap. All firefighters should consider carrying a Cearley Rescue Strap in their turnout because of its many applications to quickly secure a downed firefighter who must be dragged, lifted, or lowered. It can also be used as a hasty chest harness to pluck victims from above-ground windows or during swiftwater operations, or even as an emergency harness for self-rescue from upper floors. It has proven itself with our department when lives depend on quick and simple securing of victims for evacuation.
