| Description/Abstract | Approximately 140 additional hydrogen incident reports have been compiled during this reporting period to increase the total number of reports to about 420. A preliminary analysis of the data shows that 60 percent of the reported incidents have been hydrogen explosions and that 82% of the casualties have been due to explosions. Inadequate hydrogen detection of leaks, incomplete purging, etc., was a primary cause factor in 36% of the incidents. Recommendations are presented for research in explosion protection, hydrogen leak and flame detection, and ingnition sources associated with high speed emergency releases of hydrogen. A multivariate regression analysis has been conducted to compare the severity of hydrogen and natural gas losses at Factory Mutual insured plants. The results indicate that, after accounting for the effects of deductibles, occupancy type and inflation, there is no statistically significant difference between the severity of hydrogen and natural gas losses. A simple calculation of the frequency of hydrogen and natural gas incidents at ferrous metal processing plants indicates that there have been significantly more hydrogen incidents per unit volume or per unit energy of gas consumed. A similar calculation is presented for petroleum refinery incidents, but with less conclusive results. |
