A Red Telephone with two telephone lines (a private line and an alerting line). 2. A white exclusion key on the Red Telephone switch hook. 3. A push to talk button on the Red .Telephone hand set. 4. Loud speakers and/or head sets. A Group Alerting call is made as follows. The originator goes to the red telephone and picks up the hand set. (No dial tone is present.) He should lift the white exclusion key on the switch hook (dial tone is now present). He dials the alert code for the desired group (say 3103 for Group 3). The Group Alert is now activated. Automatic cut-thru at other stations in the group will engage the load speakers. The originator can immediately begin to describe the alert and be heard at the various stations over the loud speakers. The alerted station users can reply only by using the push-to-talk on their hand set. Note: he white exclusion key DOES NOT have to be lifted at the alerted stations. The originator jilone must do this. Care must be exercised by the originator. however;*n6t to depress*.the white exclusion key (manually or by hanging up the hand set) as this wi'lV terminate the alert. Station to station calls (within the Red Phone System using the private line) can be made without blocking the alerting paths. The originator uses the same method described above in making a Group Ale'rt, except a station number is dialed instead of an alert. Automatic cut-thru does not occur at the receiving station. The red phone will continue to ring until the receiving station picks up the hand set'and lifts' the white exclusion key. The push-to-talk feature is still required. Should an alert occur while two parties are using the private line, they should immediately hang up and listen for the alert message. The red phones are tied to an "Emergency Power" source in each control room. Loss of this power source will not prohibit'the receiving of an alert but will prohibit the initiating of an alert. A receiving station will hear the phone ring once and will have to pick up the hand set to communicate as automatic cut-thru to the loud speakers will not occur.

This means that flow still exists in the header to Plant "B", but the failure is such that the line needs to be taken out of service as soon as possible. Everybody concerned needs to realize that the normal operating strength of Waste Caustic is 90-100 GPL. In order to supply all the users, in Plant "B", with Waste Caustic instead of Cell Liquor, the Waste Caustic strength will have to be raised to 150 GPL (minimum). The basic warning is that if all the Plant "B" users switch to Waste Caustic without allowing Caustic "A" to get the strength up, it is a good chance that everybody in Plant "B" will shut down because the capacity of the supply system is such that all users cannot be supplied adequately at the lower strength.

HE "SHOULD FIRST NOTIFY CAUSTIC "A" LEAD OPERATOR (2558) TO PREPARE TO TAKE THE CELL LIQUOR TO "B" HEADER OUT OF SERVICE. HE SHOULD THEN NOTIFY VCM-II LEAD OPERATOR (2770) TO GET OFF CELL LIQUOR AND START USING WASTE CAUSTIC. THE VCM-II LEAD OPERATOR SHOULD CONTACT THE WTU LEAD OPERATOR (2677) AND GET HIM TO OPEN VALVE 1. THE WTU LEAD OPERATOR SHOULD NOTIFY THE VCM-II LEAD OPERATOR WHEN VALVE 1 IS OPEN. THE VCM-II LEAD OPERATOR SHOULD THEN NOTIFY THE TRI-II LEAD OPERATOR (2646) TO CLOSE AND TAG VALVE 2^ ONCE VALVE 2 IS CLOSED THE TRI-II LEAD OPERATOR SHOULD NOTIFY THE VCM-II LEAD OPERATOR THAT VCM-II IS NOW ON WASTE CAUSTIC. 4. CAUSTIC "A" SHOULD DO EVERYTHING NECESSARY TO START GETTING TKS. 15. & 17- STRENGTH UP TO 150 GPL (MINIMUM). AS LONG AS THE CELL LIQUOR TO "B" LONE IS OUT OF SERVICE, CAUSTIC "A" SHOULD KEEP THE WASTE CAUSTIC STRENGTH BETWEEN 150-175 GPL. TO GET TKS. UP TO STRENGTH, CAUSTIC "A" SHOULD: A. Remove all weak streams from 15 & 17 and put to the cel 1 liquor tks.. B. Leave only streams above 140 gpl in 15 & 17 and start dumping 50% caustic from filters into 15 & 17. C. Start sampling Waste Caustic every 30 minutes. Once the Waste Caustic strength gets above 150 gpl, the operator can go back to sampling every 2 hours. 5. CAUSTIC "A" WILL NOTIFY THE TRI-II LEAD OPERATOR (2646) AS SOON AS THE WASTE CAUSTIC' STRENGTH IS ABOVE 120 GPL'. TRI-II SHOULD GET OFF CELL LIQUOR AND GET ON WASTE CAUSTIC. OPEN VALVE 3 AND VALVE 4 THEN CLOSE AND TAG VALVE 5^_ S u b je c t to P ru t* a tlv # OiffjUr _____ ji ** 6. TRI-II OPERATIONS SHOULD SAMPLE THEIR CAUSTIC STORAGE TANK EVERY HOUR UNTIL THE WASTE CAUSTIC FEED CONCENTRATION COMING TO THE UNIT HAS BEEN STABILIZED. CAUSTIC "A" CAN BE CONTACTED (2558) PERIODICALLY TO SEE WHAT THE WASTE CAUSTIC FEED CONCENTRATION IS AND YOU MAY ALSO REQUEST NOTIFICATION OF ANY DRASTIC CONCENTRATION CHANGES. COW PIDKM'flALi A. It will be important to closely monitor tank levels, a* ** flows, and pH's in the cell liquor and caustic systems I in the unit. The waste caustic strength will vary, at least for a while, and care must be taken to keep the caustic strong enough to destroy all the chloral in the system and keep the pH up high enough in the steel ts 3 (O LO lines to protect them from excessive corrosion, while LO also keeping the concentration low enough to avoid CO inverting the aqueous and organic phases in th O Chloral Treatment Phase Separator (C.T. P/S). Keep tfte. strength of the caustic going to the C.T. P/S 'ieiow 8%. If the waste caustic is not strong enough CO '' to" allow the unit to operate normally, notify the Shift Supervisor and ask him to have Caustic "A" increase the strength of the waste caustic. - 7. CAUSTIC "A" WILL NOTIFY THE VDCM LEAD OPERATOR AS SOON AS THE WASTE CAUSTIC STRENGTH IS ABOVE 140 GPL. VDCM SHOULD GET OFF CELL LIQUOR AND GET ON WASTE CAUSTIC. OPEN VALVE 6 THEN CLOSE AND TAG VALVE 7. 8.-AS SOON AS VDCM HAS SWITCHED OVER, THE VDCM LEAD OPERATOR SHOULD NOTIFY THE PLANT "B" SHIFT SUPERVISOR THAT ALL USERS ARE OFF OP CELL LIQUOR. A. It should be noted that VDCM has the ability to swing their rate at will, so if the waste caustic supply is not sufficient, VDCM can cut load or temporarily come down until Caustic "A" can get the strength up high enough to supply all users. 9. THE PLANT "B" SHIFT SUPERVISOR SHOULD CHECK VALVES 2. 5. 7, AND 9 TO MAKE SURE THEY ARE CLOSED AND TAGGED. A. This is critical because if the Cell Liquor header is not isolated. Weak Caustic will be pumped back into the Cell Liquor header. 10. ONCE THE "B" SHIFT SUPERVISOR HAS MADE SURE THE VALVES ARE CLOSED AND TAGGED, HE SHOULD NOTIFY THE SHIFT SUPERINTENDENT THAT ALL USERS ARE OFF CELL LIQUOR. THE SHIFT SUPERINTENDENT SHOULD THEN TELL CAUSTIC "A" TO SHUT DOWN THE CELL LIQUOR TO "B" PUMPS. 11.
