Many cities and towns when asking for bids for motor-driven fire apparatus use specifications that are verbose and sometimes even impracticable, sometimes to an extent as to create confusion. Recently some very concise specifications were issued by the City of Pittsburgh, Pa. The Director of Supplies gave permission for their publication and a copy, with some slight alterations, is printed herewith, as they may be of interest and value to the authorities of many cities and towns who contemplate purchasing apparatus. These specifications are broadly drawn, easily covered by first class builders of fire apparatus
