Sessions Held on Unified Training Activities and Problems, and on Use of Motion Pictures as an Educational Media

THE twelfth annual meeting of the Fire Department Instructors’ Conference was held in Memphis, Tenn., January 9 to 12, with the Memphis Fire Department acting as host. This is the sixth successive year that the Conference, under the joint sponsorship of the Western Actuarial Bureau and the Memphis Fire Department, has met in that city. The conference this year, as in the past, was under the Chairmanship of Richard E. Vernor of the Western Actuarial Bureau.

Large Registration

Approximately 250 representatives from twenty-five states and the District of Columbia were registered. Those in attendance included prominent chiefs, paid and volunteer; assistant chiefs; subordinate officers; drillmasters; fire prevention superintendents; representatives from state departments of education and from state universities; state training program supervisors and instructors; state Fire Marshals; insurance rating bureau engineers; fire prevention experts and many others interested in the advancement of training methods in the fire service.

Hon. Clifford Davis, Vice-Mayor of Memphis, and Commissioner of Public Safety, welcomed the delegates. Four morning sessions were devoted entirely to the presentation of addresses, papers and demonstrations on topics of current interest in the training field.

Special luncheon features included a major address each day. Afternoon sessions were largely given over to a general conference on the subject of unified training activities and the problems involved in organizing and administering state and local training programs.

Exhibition drill evolutions were staged at the fire department drill tower. Of special interest was the exhibition drill put on by members of the Sebring, Ohio, Junior Fire Department.

Motion Pictures for Training

Two evening sessions were devoted to discussion of the advantages of using motion pictures in fire training, fire prevention, fire investigation and public relations work. Several interesting pictures were shown to illustrate how they might best be used to advantage. Special meetings were also arranged for insurance rating bureau engineers, and for the International Association of Fire Department Instructors.

The conference session was climaxed by a buffet supper and dance arranged by the Memphis Fire Department.

Delegates to the Conference were loud in acclaiming this year’s session the most profitable from the viewpoint of actual accomplishment and enthusiasm.

Hydraulic Loss in Fire Hose Reviewed

The Underwriters Laboratories recently announced an issue in their Research Bulletin Series, Bulletin No. 12, entitled “Hydraulic Friction Losses in 1 1/2-inch and 2 1/2-inch Cotton RubberLined Fire Hose.”

The material contained in the bulletin is the result of research conducted by the Hydraulic Engineering Department of the Laboratories. Determinations of loss of head due to fluid friction with water flowing under pressure in cotton rubber-lined Hose have been made a number of years ago. The purpose of this study was to develop information of this kind with regard to hose manufactured by present-day methods. The investigation was limited to the more commonly used l 1/2-inch to 2 1/2-inch sizes of hose. Assuming that the loss of head was affected by the number of cotton jackets on the hose, tests were run on single and double-jacketed hose.

A description of the laboratory set-up and the test methods, accompanied bv illustrations, are included in the bulletin. The method used in conducting each test is described, and a table of results obtained from each test is given.

As a result of this investigation, the following conclusions are indicated:

  1. A tendency for the loss of head to decrease with an increase of the effective water pressure.
  2. That, other contributing factors being equal such as lining roughness, single jacketed hose offers less resistance to water flow than double jacketed.
  3. The labeled hose made with present-day methods, and considered from the standpoint of averages, has a slightly lower loss of head than the hose previously investigated.
