Time-dependent action steps

DOE-STD-1029-92

EXAMPLE 4-11. Time-dependent action steps.

NOTE

The following action step starts a time-limited sequence. Action steps [2] through

[5] are to be performed within 20 minutes.

[1]

Calculate the time by which action step [5] is to be completed by the following steps:

[a]

Record the time that action step [2] is to be started.

[b]

Add 20 minutes.

20 minutes

[c]

Record the time that action step [5] is to be completed.

Complete by

Place the Incident Action switch to TEST.

[2]

[3]

Verify the amber ALARM TEST light on the AIA graphic panel is LIT.

[4]

Place the Incident Action switch to OFF.

[5]

Push the RESET pushbutton on the AIA logic tester and record the time.

[6]

IF the time recorded in action step [5] is later the time recorded in action step [1] [c],

THEN REPEAT action steps [1] through [5].

[4]

A note advising of time-dependent actions and instructions to record the time

information are not required when the time requirement is an inherent part of the

action step and misunderstanding is unlikely.

EXAMPLE 4-12. Time-dependent action step.
