Abstract
This report investigates the gas-cooling effects of compressed air foam (CAF). A literature review has been made on the subject and on related issues in order to gather information. Two experimental series were conducted, the first to evaluate the gas-cooling properties of CAF compared to water. The other one was conducted to investigate how the recommended tactic, with application from a safe distance, would affect the temperature and thereby the need for traditional gas-cooling. The results from the first experiments show that CAF has a gas-cooling effect but is less effective than water. The second series of experiments indicate that the suitable tactics may limit the need for traditional gas-cooling.
However, the data is limited and... (More)
