This specialized line is often utilized in various emergency situations, including water rescue operations, mountain or cliff rescues, and even in hazardous industrial environments. It is commonly employed by trained rescue personnel, such as firefighters, lifeguards, rope access technicians, or search and rescue teams.
In water rescues, a rescue line may include additional flotation devices or buoys to aid in keeping victims afloat and preventing them from drowning. The line is thrown or deployed to individuals in distress, giving them something to hold onto while rescue personnel facilitate their extraction from the water.
In cliff or mountain rescues, a rescue line is used to secure rescuers and provide a method for them to reach or help stranded individuals. It is often coupled with harnesses, carabiners, and other climbing equipment to ensure the safety of both the rescuers and the victims.

The word "rescue" comes from the Old French "rescourre", which means "set free, deliver". It further traces back to the Latin word "rescussus", which means "recovered" or "revived".
The word "line" originates from the Middle English word "lyne", derived from Old English "līne" and Old Norse "lína", which meant "rope" or "cord". It is ultimately derived from the Proto-Germanic word "*līnō", which had a similar meaning.
Combining these two words, the term "rescue line" refers to a cord or rope used to save or deliver someone from a dangerous or difficult situation.
