When he first started in the fire service, Shelley recalls that 2 1/2-inch hose was prominent in their apparatus housebeds, which were divided equally between 1 1/2- and 2 1/2-inch hose. In the ensuing years, the Fire Department of New York's Lieutenant Andrew A. Fredericks highlighted the need for 2 1/2-inch attack lines for situations that require large volumes of water, such as the initial attack at structural fires. The question, however, is whether the hoses are adequate to respond to a major tank truck spill that requires large amounts of foam to extinguish. Here, he presents a hypothetical situation that could happen anywhere in the US and discusses the adequacy of the fire equipments.
