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.

Famous quotes containing the word history:
“The awareness that health is dependent upon habits that we control makes us the first generation in history that to a large extent determines its own destiny.”
—Jimmy Carter (James Earl Carter, Jr.)
“What is most interesting and valuable in it, however, is not the materials for the history of Pontiac, or Braddock, or the Northwest, which it furnishes; not the annals of the country, but the natural facts, or perennials, which are ever without date. When out of history the truth shall be extracted, it will have shed its dates like withered leaves.”
—Henry David Thoreau (1817–1862)
“English history is all about men liking their fathers, and American history is all about men hating their fathers and trying to burn down everything they ever did.”
—Malcolm Bradbury (b. 1932)
