- Abstract
- Results are given of fire tests on samples of seven different bulb-type carbon-tetrachloride fire extinguishers ranging in capacity from 0.44 to 1.75 quarts. Six of the extinguishers were tested both for manual and automatic operation. The seventh device was tested for automatic operation only, since it was not designed for manual use. The tests of the devices as automatic extinguishers were conducted in a room with ventilation just sufficient to permit the test fires to burn freely unitl the fuel was consumed, with no extinguishers present. The test results showed that the bulb-type carbon-tetrachloride fire extinguishers, as represented by the samples tried, when operated by hand were distinctly less effective than the ordinary one-quart carbon-tetrachloride pump-gun extinguisher, and when employed as automatic devices were not effective for the protection of enclosed space. The seven devices were tested in the number recommended by the manufacturer and six of them were also tried in double that number.
