Note: The entries in this table are for illustrative purposes only

The descriptions of the example summary hazard table entries are as follows:

1) Identification Number the unique scenario identifier;

2) Weapon Configuration/Process Step(s) includes both the configuration of the weapon and the

steps of the process applicable to that configuration (distinction of process steps is needed to

account for steps that require different controls);

3) Hazard and Parameters identifies the hazard of concern (e.g., ESD), the parameters that affect

the hazard, and their probabilities (e.g., voltage and capacitance for ESD and the probability the

energy will be deposited);

4) Control Description identification of the controls and the failure probabilities;

5) Other Parameters listing of other parameters that contribute to the specifics of scenario

progression including weapon response; and

6) Scenario Description provides a summary of the combinations of occurrence for initiating

event, occurrence of other events, and failure of controls and their associated probabilities.

For some complex hazard scenarios, the development of the summary hazard table may need to be

augmented with event trees and/or fault trees that break out certain events into more basic events. In such

cases, the summary hazard table will simply reference the applicable analysis, but the results must still be

included in the summary hazard table.

6.2 Weapon Response

6.2.1 Screening Tables

Hazards and associated weapon configuration combinations that cannot result in a weapon response are

identified in a screening table issued by the DA. The screening tables must be accompanied with bases

information that include the weapon configuration and the screening rationale with reference to

appropriate and defensible documentation. The screening tables should be approved by the applicable

DAs for use in a time frame to support the hazard analysis development.

6.2.2 Requesting Weapon Response

The weapon configurations, hazards, and parameters for scenarios (that cannot be screened utilizing the

screening tables) are documented in a formal weapon response request prepared by the PPC utilizing the

Engineering Authorization System or equivalent. Weapon response requests must be forwarded to the
