A SURVEY OF FIRE PREVENTION PROBLEMS IN CLOSED OXYGEN-CONTAINING ENVIRONMENTS

Abstract

The problem of fire ignition and flame propagation in oxygen- containing or oxygen-enriched environments is dependent upon both the percentage of oxygen, oxygen partial pressure, and presence of the diluent inert gas. Oxygen percentage is the single most important feature and its effect is most strikingly greater than 42 per cent. The diluent gas affects the initial combustion temperature and the rate of propagation. Helium requires a higher ignition temperature, but produces an increased spread; while nitrogen requires a lower ignition temperature, but shows a decreased propagation rate. The most effective extinguishment system employs a hand-held, high-pressure, water hose. However, specific prevention measures are mandatory when dealing with these environments.
