Analyzing the impact of in-rack sprinklers in a warehouse fire: A demonstration of the role optimization has in mitigating damage

This study presents a tool that illustrates the potential and role that optimization can have in fire protection design and performance. Specifically, the tool uses validated engineering correlations to simulate a warehouse fire, and evaluates whether it is controlled by modeling the placement and number of sprinklers – both in-rack and ceiling. Using initial model inputs that include storage configuration, commodity type, water supply, and sprinkler type, we allow a fire to ignite and simulate its growth behavior and corresponding effects on a nearby target array. For any initial set of input parameters, our tool demonstrates the minimum number and location of available in-rack sprinklers to control the flame spread. With reasonable run times, our work yields new insights into the design of sprinkler systems and, more broadly, the usefulness of optimization in fire protection design.

Effectiveness of sprinklers in reducing fire severity

The effectiveness of sprinklers is examined by comparing fires they extinguish or control with fires they fail to extinguish or control. It is shown that sprinklers substantially reduce the probability of fire area exceeding 100m² but that they normally have little effect until the fire area reaches 3 m². The effect, of sprinklers on the incidence of damage to the building fabric is also looked at.

This paper is part of a research study aimed at developing quantitative fire engineering methods for the assessment of fire risk. The results will be used to calibrate the mathematical models on which these assessments are based.

Factors influencing the use of high-temperature sprinklers

High-temperature sprinklers—when and where to use them—are a subject of interest to fire protection engineers. In a series of small-scale and large-scale fire tests, Underwriters' Laboratories, Inc., evaluated conditions under which high-temperature sprinklers should and should not be used. The value of increasing water supply pressure to sprinklers of ordinary rating was also investigated. Underwriters' Laboratories, Inc.

Limited-water-supply sprinklers for manufactured (mobile) homes

A prototype limited-water-supply (LWS) sprinkler has been developed for manufactured (mobile) homes in a research program sponsored by the United States Fire Administration. The LWS sprinkler is designed to be installed at a 2.44 m (8-foot) spacing and to have a total water supply of 380 (100 gallons). The installation spacing was determined in a series of freeburn fire tests that indicated that the heat release rate at sprinkler actuation could be halved by reducing the sprinkler spacing from 3.66 m to 2.44 m (12 feet to 8 feet). A series of eight fullscale fire tests, including a corner living room scenario similar to that used in the Los Angeles Residential Test Program, was conducted to evaluate the performance of the prototype sprinkler. In five of the tests, room tenability was maintained during the 10-minute period following the actuation of a single sprinkler at a flow rate of 38 pm (10 gpm). In three tests, tenability was maintained with multiple sprinkler actuation (2 or 3 sprinklers) and a total system flow rate of 49 pm (13 gpm). The spray of the sprinkler was characterized in terms of its water flux distribution and drop size distribution. The thermal sensitivity requirements of the sprinkler are to be based upon RTI, C, and temperature rating, which would ensure that sprinkler actuation would occur at fire sizes comparable to those encountered using the prototype LWS sprinkler in this study.
