Question:

A set of nonredundant (1oo1) safety equipment is used to implement a SIF. Demands are expected every minute and DTI is 40 seconds. The following failure rate data are obtained by adding the failure rates of all component categories:

λDD = 8.5 • 10^-6 failures per hour

λDU = 0.5 • 10^-6 failures per hour

What is the demand mode? Based on SIL probabilistic verification, what SIL level is achieved by this design?
