NEW ENGLAI~D ASSOCIATION OF FIRE CHIEFS
Our next question is an interesting one, from an unknown respondent,
and here it is.
Will, in your opinion, the fog nozzle displace the solid stream nozzle, or
the 2 ½ inch straight stream?
Well, now, I thought the 2 ½ inch straight stream and the solid stream
nozzle were identical, but maybe I am wrong. If the person who propounds
this question wants to amplify it, I will be glad to have him do so. Otherwise,
I would interpret it: Willthe fog nozzle, not the universal type, displace
a control nozzle? ¯
Chief Marshall, do you want to say anything on that subject?
CHIEF MARS~AV.V.: No.
MODERATOR WOOLLEY: I believe that our Panel will agree that there
will never be any such displacement. I think that our attendance here will
agree it is like saying that foam displaces all other types, of extinguishers.
They each have their place, and will be used.
I doubt that it will be necessary to .go into this, unless the one who a~ked
the question wishes to amplify it a bit. And if he doesn’t want to speak up,
himself, does anybody on the floor want ~to speak for him, because I don’t
want to have him feel that we. have passed too lightly over a question that
he has given to us.
CHIEI~ THOlVIAS: First, we all agree with you that the fog nozzle will not
replace the straight stream for all purposes. The fog nozzle definitely has its
place, and the straight stream, also., in large fires.
My purpose in standing up at this time, Roi, is to tell all of our members
here that there is a great deal being done on further research of the fog nozzle,
and that the survey that was made to determine nozzle impressions, and optimal
discharges, at Elmira, is the first step and that study is being continued,
and the study as to the optimum pressure s and volumes, together with the
pattern of the stream, will be continued by our sub-committee, of which you
are a member, Roi, at the University of Maryland.
I also wanted to say at this time, Roi, that you are very fortunate, becauseof
the help and assistance of Kyle Laughlin, sitting over here, and being able
to get some money from the Federal government, so that in cooperation
with the Forestry Department, we are going to go into that research.
There is also going on, a continuing test, of the Underwriters’ Laboratory,
to determine the optimum size of droplets.. I do believe that at the conclusion
o£ this, and because of the cooperation of~ all concerned, that the fog nozzle
and its uses will be better understood by the National Fire Service, or our
Fire Service.
MODERATOR WOOLLEY: Thank you very much, Henry. I think that that
is a very pertinent observation, and I believe that it provides a very good
answer to the question.
At this time, I should like to introduce a man, and I believe that he hasn’t
been here in some years; his predecessor was well-known here. I don’t think
that anybody in this country has contributed more, or, let me say that I don’t
think any Fire Department has contributed more to the advancement of water
fog than the New Haven Fire Department. And, we have with us, Chief
