Revision 0 LODI: TY\PF PROCEDURES <br /> LUSTRE-CAL PF PROCEDURES <br /> PF PROCEDURES - ETCH ROOM ASSOCIATES <br /> PF Liquids or other designated spent chemicals can only be accumulated for a <br /> maximum of 90 days. Before the 90-day period expires, all accumulated chemicals <br /> must either be shipped off-site for recycling/disposal, or placed in the process. All <br /> Associates handling PF solutions, either new or spent shall do so only after adequate <br /> training. <br /> Toward the end of the 90-day period, the addition of"Virgin" (New) PF to the In- <br /> Process "clean" Container [IPC] needs to be coordinated with the processing <br /> (emptying) of the PF Accumulation Containers [PFAC]. Space needs to be available in <br /> the IPC so that one drum of Skim PF Liquids can be returned to the process before the <br /> 90-day expiration on the PFAC's. <br /> 1. Always wear appropriate PPE. <br /> 2. Inspect PFAC for Out of Service Date. <br /> 3. Inspect and log In Process "Clean/Reclaimed PF"and PFAC levels prior to <br /> transfer. <br /> 4. Skim "Clean/Reclaimed PF"liquid from the PFAC to the IPC. <br /> 5. Pump spent "Dirty PF"from PF Processing Tank (Etch Room) to PFAC's. <br /> 1. Associate will obtain appropriate PPE: rubber or nitrile gloves, safety glasses and <br /> apron. <br /> 2. Associate will inspect PFAC's (in the PF Room) every day at the beginning of <br /> his/her shift, before any PF transfers are made. Various container levels are <br /> determined and recorded on "LOG of PF USE" chart (in the PF Room). <br /> 3. Associate will inspect "End of Process" date. Has it arrived? <br /> a. If"yes," tell the [Purchasing Manager] to contact Waste Handler Associate to <br /> exchange PFAC's. <br /> b. Note: when the PFAC's are exchanged, skim PF liquids to IPC's, but do not <br /> pump "Dirty PF" from the Etch Room until empty PFAC's are in place. <br /> 4. Associate will inspect "Log of PF Use" and determines from the previous entry, <br /> approximately how many inches of PF are to be skimmed from the PFAC's to the <br /> IPC's. <br /> 5: Associate will inspect IPC's to determine if there is adequate capacity (enough <br /> inches of space) to contain the skimmed liquids. <br /> a. The space available in the IPC's needs to be at least 2" more than the amount of <br /> liquid to be skimmed. This will leave only seven gallons of headspace. There is <br /> not much room for error. <br /> b. If there is not enough room to skim all the available material from the PFAC's, <br /> MAKE SURE WHEN YOU SKIM THAT YOU DO NOT OVERFILL THE IPC! <br /> Print Date 10/19/00 Page 1 of 2 <br />
