Manual of Fire-Loss Prevention of the Federal Fire Council
From preface: "This issue of the Manual of Fire-Loss Prevention, the first edition of which was published in 1934, includes revisions and additions made in part to cover improvements in the past 10 years in methods of preventing and controlling fires. Such methods remain dependent largely on the elimination of preventable fires and abatement of loss from those that originate, by the use of appropriate designs and materials in building construction and the installation of applicable fire alarm and extinguishing equipment, to the extent justified by the hazard" (p. ii).
