The full-scale building occupancy was required to accommodate cut-off room door openings ranging from 1.86 × 3.73 m high up to 3.73 × 3.73 m. The fire challenge was a heptane spill fire cascading from the top of a 1.83-m dia. by 2.74-m high steel tank at a spill rate of 37.9 L/min. Two off-the-shelf nozzles were selected as candidates for the full-scale building to approximate the scaled-up water mist spray requirement. At a discharge pressure of 90 bar, one nozzle discharged 28 L/min, with a spray angle of 100° and a volume-median droplet dia. of 115 µm; the other discharged 24.4 L/min, with a 180° spray angle and median dia. of 96 µm. Nine nozzles were arranged at the ceiling level in a 3 × 3 matrix with a spacing of 1.86 × 1.86 m. Before the two candidate protection schemes were challenged with the spill fire, scaled-up heptane pool fires were used to ensure that the fire extinguishing propensity was consistent with that observed in the ½-scale enclosure. The pool fire tests showed that the nozzle with the smaller spray angle provided better fire extinguishing performance, which was later confirmed in the spill fire tests. The protection scheme with the smaller spray angle could extinguish the spill fire for door openings up to 3.05 × 3.05 m. For larger openings, two additional downward water mist sprays were required in the door opening to expedite fire extinguishment by reducing ventilation through the door opening. Water mist protection could provide adequate cooling to fuel tanks as long as such protection could extinguish the fire. Overall, the investigation demonstrated that physical scaling is a useful tool to provide an engineering estimate of water mist protection requirements.

However, the use of a single parameter has been criticized since it can result in poor system designs. This study evaluates additional parameters in order to improve the characterization of system performance. Two series of fire tests were conducted with a number of water mist and water spray fire protection systems: the former in a 500 m3 test compartment using three different systems; the latter in a 250 m3 compartment using four different systems. The heat release rate of the fire and the gas temperatures inside the test compartment were measured. Based on these measurements, the fire suppression capability of the systems, their temperature reduction capability and their ability to mix water vapor, water droplets and combustion gases within the compartment were determined. The tests revealed that the time to extinguishment varies several tens of percent under identical conditions. It was also observed that the relative performance of the systems was influenced by the size of the fire. The results obtained with the additional parameters were much more repeatable and consistent than using time to extinguishment alone. It is concluded that fairly simple and inexpensive measurements can improve current fire test procedures.

Experimental results show that whether a gasoline-air explosion occurs or not is determined by a critical relative humidity when the temperature of the heat source is maintained at a specific value. Under the experimental conditions in this study, when the heat source temperature is maintained at 550℃, the critical value of relative humidity is 32.3% ± 0.2%, and when the heat source temperature is maintained at 570℃, the critical value of relative humidity climbs to 37.7% ± 0.2%. The occurrence of gasoline-air explosions is very sensitive to the gas mixture temperature. It is shown that an explosion will not occur if the gas mixture temperature is lower than the critical value of 26℃. Influenced by slow oxidation reactions, concentrations of reactants can decrease below the explosion limit range, resulting sometimes in no observed occurrence of gasoline-air explosions. Experiments show, in this case, that the critical heat source temperature for the gas mixture explosion, defined by a probability of explosion occurrence of 20%, climbs from 510 to 550℃, i.e. it increases 40℃ solely due to the influence of slow oxidation reactions.
