Elevator leg explosion as a function of specific failures
1990
Jones, D.D. | Brusewitz, G.H. | Goforth, K.J.
A sensitivity analysis was performed, using the Jones et al. (1989) computer model, to estimate the effect on the probability of a grain dust explosion in a bucket elevator leg of specific factors, including: grain dust in concentrations adequate to support combustion, bearing failures, bearing maintenance and monitoring failures. The probability of a leg explosion increases exponentially with increased probability of bearing and bearing maintenance failures. The probability of a leg explosion increases, but at a decreasing rate, with increased probability of occurrence of fuel. Increasing the probability of operational monitoring failures produces a small linear increase in the probability of a leg explosion.
