5.0 PROCEDURE

Special Instructions

Failed functional checks require documenting results on work record and data sheet and

following the requirements in the Tank Farm Contractor Work Control procedure (reference

TFC-OPS-MAINT-C-01).

- Data recording is done on POR126 Data Table 1 within this procedure, and attached to

data sheet after completion.

- Exhaust fan may shut down unexpectedly and may be restarted per applicable

operating procedure, as necessary to facilitate completion of this procedure.

- Alarms/annunciators at the following locations may be re-acknowledged as necessary:

Exhauster HMI

Continuous air monitor.

5.1 Initial Conditions

5.1.1 IF functional checking cannot be performed in accordance with this

procedure, PERFORM the following:

5.1.1.1 RETURN equipment to a safe configuration,

5.1.1.2 STOP work

5.1.1.3 NOTIFY Shift Manager and OE.

NOTE - It is not unusual for the "LOW BETA COUNT" alarm to be activated upon

initially energizing the CAM which is done by the Programmable Logic

Controller after the exhauster motor is started. This may be due to software and

clearing status registers anomalies. The "LOW BETA COUNT" alarm will

shut the exhauster back down. If this should occur it is permissible to reset the

alarm and continue with exhauster startup NO MORE THAN twice after which

it should be treated as an actual CAM failure alarm and action taken as

required by alarm response procedures.

5.1.2 LOGIN at HMI with Technician User Name and access level password.

5.1.3 CHECK CAM calibration AND RECORD
