- Abstract
- A series of large-scale fire tests were undertaken at the U.S. Coast Guard Shipboard Fire and Safety Testing Facility, Mobile, Alabama. These tests were intended to determine the effectiveness of Halon 1301 when used as an extinguishing agent for machinery space fire protection. Pre-burn lengths were varied to determine the effect of fire intensity on the pyrolysis products of the agent. Additionally, discharge times were varied to measure the same effect. Two different systems were utilized in the series; the first system was a nitrogen-super pressurized system, and the second system obtained its design pressure from a heat source. All fires were successfully extinguished. It appears that the volume of pyrolysis products producted from breakdown of the agent is a function of the discharge time rather than of fire intensity.
