PROCEDURE 1.
Contact the Rac/ Chem Department for reccmmenaations as to equipment requireo cased on the monitor response.
2.
Contact tne Rad /Cnem Department for reccmmendations I
as to cosimetry, clothing anc respiratory requirements to enter the samoling arda anc ootain the sampla.
3.
Notify tne Unit Operator in the Control Rcom of tne liquid process raciatian monitor to oe removec from service for sampling.
Refer to Attachment A.
4 Monitor cose ratas continuously as tne sample area is approacned and the sample is ootainea.
S.
9inimize the time at tne sample location.
6.
Secure tne sample panel pump.
Isolate tne monitor oy closing the Inlet (1) and Cutlet (2) valves.
ncTE Numbers in parentheses refer to Attachment B numDering system.
7.
Check shut tne vent valve (3).
8.
Remove tne cap from the vent valve (3) and attaen the l i quia process moni tor vent rig.
9.
Vent any resicual pressure in the liquia process monitor into tne vent rig oy slowly opening the vent I
valve (3) the minimum amount necessary to acnieve venting.
Leave the vent val ve (3) in this tnrottlea cosition.
10.
Flusn tne vent line into tne vent rig tnrougn the vont valve (3) oy caref ull y and slowly cpening tne Inlet valve (1).
Shut tne Inla; valve (1) after flushing approximately 1 liter of water into tne vent rig.
