Hyperbare Abbranduntersuchungen Abschlussbericht

Abstract

A fire burst within a diving chamber indicates greatest risk for diver's health. The burning behavior of some materials typically fitted within diving chambers was analysed within diving mixed gas atmospheres consisting of 5% nitrogen, oxygen varying and helium filled up to 100%, which are used for saturation diving down to 600 m waterdepths. With reference to the minimum oxygen concentration necessary for flammability/burning of these materials no disadvantageous properties could be demonstrated compared with already known worst-case-conditions of hyperbaric burning. Consequently the test results confirm the conservative nature of fire safety evaluation for saturation diving based on the paper strip burning experiments performed by Dorr. Further experiments related to the composition of some smoke fumes which will be expected after a fire at a typically equipped pressurized air building site.
