Example text

The sprinkler operating pressure was typically varied during each test from 10 psi to 150 psi, unless the test was terminated early due to the growth of the fire condition. The tests investigated the impact of several variables in causing ignition of antifreeze sprays. 1 Sprinkler Tests of 50% propylene glycol solution were conducted for the full range of sprinklers investigated. The graph that follows shows the increase in heat release rate due to an antifreeze spray of 50% propylene glycol for the range of sprinklers.

The 50% propylene glycol solution discharged at a height of 8 ft had an increase in heat release rate of approximately 5,000 kW while discharge at a height of 20 ft yielded an increase in heat release rate of approximately 1,200 kW. Thus, while the sprinkler and antifreeze concentration seem to be of primary importance in determining the potential for ignition, the change in spray distribution with height can significantly impact the results for marginal solutions. B 4 Scope B – Room Fire Tests 29 Temperature of Antifreeze Solution Tests were conducted that compared the performance of glycerin solution at ambient temperature (80°F to 90°F) and glycerin solution heated to 140°F.

This report documents concerns with the use of certain concentrations of glycerin and propylene glycol antifreeze solution. Thus, there is a need to develop alternative solutions that could be used in instances where glycerin and propylene glycol are not suitable. D Develop a Listing Standard for Solutions Introduced into Sprinkler Systems 43 Issues of flammability, freeze protection, toxicity, and material compatibility would need to be addressed for any solutions that are introduced into sprinkler systems.
