In buildings ofthe office and hotel types, such ceilings affi)rd sufficient protection for the soffits of the floor beams. Portable safes and small \-aults gave very unsatisfactory results. In many of the large office buildings,particularly those of Class B construction with wood floors, fires of sufficient intensity occurred to incinerate the contents of the largest safes. Many of these were of standard makes and supposed to Safes and Small Vaults. , r«. • .1 /• • ,• , ,1 • ^ ^ ii n 1 • be sufficiently nre-resisting to ])reserve tlieir contents, the waifs being in many eases8 to 12 thick and filled with composition non-heat-conducting materials.

A Standard Underwriters metal covered door separated this vault from the basement of thebuilding. The tire destroyed the door, igniting the contents of the vault, causing the total and partial failure of thecast-iron columns, and the failure of a section of the concrete arches supported by them. A double fire-proof barrier inthe door opening of this vault would probably have saved the contents. Crossley Building, became heated to such a degree tliat not only were the paper contents reduced to black ashes,but silver coins were partially fused, entire packages or rolls of 20 silver dollars being fused together into one jjiece.
