Abstract:

The International Sprinkler, Smoke and Heat Vent, Draft Curtain Fire Test Project organized by the National Fire Protection Research Coundation (NFPRF) has brought together a group of industrial sponsors to study the interaction of sprinklers with roof vents and draft curtains of the type typically found in large warehouses, manufacturing facilities, and warehouse-like retail stores. The Technical Advisory Committee consisting of representatives of the sponsoring organizations and other interested parties planned and conducted thirty-nine large scale fire tests in the Large Scale Fire Test Facility at Underwriters Laboratories in Northbrook, Illinois. Thirty-four experiments were performed with a heptane spray burner, five were performed with racks of Group A Plastic commodity. The test parameters were chosen to address relatively large, open-area buildings with flat ceilings, adequate sprinkler systems and roof venting. In parallel with the large scale fire tests, a program was conducted at the National Institute of Standards and Technolgoy to develop a numerical field model incorporating the physical phenomena of the experiments. Bench scale experiments were performed to provide inputs for the Industrial Fire Simulator 2 (IFS2) model in terms of the thermal properties of the sprinklers and vent links, spray distribution, and commodity burn rate.
