For detailed information about this series, see: Lego Res-Q at Brickipedia
The first set that is considered by some part of the series is 2882 Speedboat, released in 1997, that features a lifeguard minifigure similar to some from actual Res-Q sets, however it doesn't feature the Res-Q logo, so it's at most a prototype.
The actual Res-Q sets were released in 1998, and are:
- 2962 Res-Q Lifeguard
- 6415 Res-Q Jet-Ski, later re-released as 6428 Wave Saver and as 1097 RES-Q Runner.
- 6431 Road Rescue
- 6445 Emergency Evac
- 6451 River Response
- 6462 Aerial Recovery
- 6473 Res-Q Cruiser
- 6479 Emergency Response Center
Additionally, the Jack Stone sets 4603 Res-Q Wrecker, 4606 Aqua Res-Q Transport and 4622 ResQ Digger, released between 2001 and 2002, feature "Res-Q" in their title, but they are not an actual part of the series.
