History
- To simplify the complex calculations of manually adjustable nozzles, Clyde McMillan the founder of Task Force Tips on a napkin invented the automatic nozzle on May 10, 1968.
- Interestingly, although the NFPA had, in 1964, ordered NFPA 1964 that all automatic nozzles must maintain flow rates within fifteen GPM of their nominal value (most commonly 100 PSI), many firefighters mistakenly continue to use stream shape instead of the recoil felt during operation to judge fog nozzles' flow rate.
