Abstract

The failure mode analysis for any cryogenic system includes the effects of a large liquid spill due to vessel rupture or overfilling. The Oxygen Deficiency Hazard (ODH) analysis for this event is a strong function of the estimated heat flux entering the spilled liquid. A common method for estimating the heat flux is to treat the surface on which the liquid spills as a semi-infinite solid. This note addresses the effect of linearizing the temperature profile in this form of analysis, and shows it to cause the calculated flux to be underestimated by more than a factor of two. 3 refs., 2 figs.

D0 Detector Assemble Hall Platform Oxygen Deficiency Hazard Analysis

Technical Report Clark, D.; Michael, J.

Liquid cryogens, released and warming to atmosphere conditions, expand to, on average, seven hundred times their liquid volume, and displace vital atmospheric oxygen. An oxygen deficiency hazard analysis assesses the increased risk to personnel in areas containing cryogenic systems. The D0 detector platform area ODH analysis has been approached four different ways using established methods. In each case, the analysis shows the platform area to be ODH class 0 as equipped (with ventilation fans) and requiring no special safety provisions. System designers have provided for a reduced oxygen level detection and warning system as well as emergency procedures to addressmore »« less

Diffusion of gases in air and its affect on oxygen deficiency hazard abatement

Conference Theilacker, J; White, M

Density differences between air and released gases of cryogenic systems have been used to either require special oxygen deficiency hazard (ODH) control measures, or as a means of abatement. For example, it is not uncommon to assume that helium spills will quickly collect at the ceiling of a building or enclosure and will efficiently exit at the nearest vertical penetration or vent. Oxygen concentration reduction was found to be detectable during a localized helium spill throughout the entire 6.3 km Tevatron tunnel. This prompted us to perform diffusion tests in air with common gases used at Fermilab. The tests showedmore »« less

ODH, oxygen deficiency hazard cryogenic analysis

Conference Augustynowicz, S

An oxygen deficiency exists when the concentration of oxygen, by volume, drops to a level at which atmosphere supplying respiratory protection must be provided. Since liquid cryogens can expand by factors of 700 (LN{sub 2}) to 850 (LH{sub e}), the uncontrolled release into an enclosed space can easily cause an oxygen-deficient condition. An oxygen deficiency hazard (ODH) fatality rate per hour ({O}) is defined as: {O} = {Sigma} N{sub i}P{sub i}F{sub i}, where N{sub i} = number of components, P{sub i} =probability of failure or operator error, and F{sub i} - fatality factor. ODHs range from ``unclassified`` ({O}<10{sup {minus}9} 1/h)more »« less
