Aberdeen Plant Employees Interoffice Communication From: Date: Subject: A. H. Sather March 18, 1985 PLANT ALARM SYSTEM Effective 3/19/85 the plant will change from the Siren to the Galtronics Alarm System. The Siren will be retained as a back-up, near term. Emergency conditions are still to be reported to the vinyl control room via telephone extension 2200, radio or Gaitronics. Control room personnel will sound the alarm and then repeat the nature of the conditions and its location three times over the public address and Gaitronics systems. The plant will also initiate a weekly test of the new alarm system. The test will be conducted on the same days as the fire system tests (Wednesday or Thursday) at 11:30 a.m. by Vinyl department personnel. The test will be conducted in the following sequence after the test is announced over the P.A. system. Fire Vapor Release Evacuation Severe Weather All Clear In each case, the test will be concluded by an announcement over the P.A. system. A. H.

W&T6 February 20, 1985 Subject: RAILCAR AND TRUCK LOADING Per plant safe work procedures, two people must be present during hopper car and truck loading. The requirement for a second person during these activities has been established for the following reasons 1) To provide a "spotter" when railcars are moved over road crossings. 2) To provide a trackmobile/truck driver such that movement by the Yard Operator from the top of the railcar or truck to grade can be minimized. 3) To provide backup personnel to assist the Yard Operator should safety problems develop. There will be occasions when personnel are unavailable within the Yard Department and assistance must be provided by other plant departments to ensure safe loading operations. This situation will occur more frequently on back shifts, weekends and holidays when only one Yard Operator is on duty. The following guidelines are to be followed when Yard personnel require assistance for railcar or truck loading from other departments: 1) The Shift Supervisor over the unit where product is to be loaded is responsible for providing/obtaining assistance for the Yard Operator. 2) The additional personnel can be obtained from an operating department or the laboratory. 3) The Yard Operator will load the truck or railcar and sample and seal all compartments from the top Immediately follow ing completion of the loading. 4) The employee operating the truck or trackmobile will take the bottom samples, close all bottom valves, and install seals and tags on all bottom outlets. 5) The samples will be collected and placed in the sample box with the drop order. The laboratory should be notified such that personnel can pick up the samples and log in the truck or railcar. If the additional personnel were pro vided from the laboratory, such personnel should return to the lab with the samples and drop order(s).

It is the Yard Operator1s responsibility to ensure that the railcar or truck is properly secured, top and bottom. If you have any questions, please see your supervisor or me. J. W.

These regulations require us to notify the State at least 20 days prior to the removal of certain amounts of asbestos material, and to develop procedures which will insure that zero emissions of asbestos will occur when the asbestos is removed. This specifically covers: 1) Removal of more than 260 linear feet of asbestos from pipe(s); 2) Removal of more than 160 square feet of asbestos from tanks. reactors, etc. / If a job is being planned in which asbestos will be removed in amounts greater than the above limits, do NOT remove the asbestos until process engineering has satisfied the appropriate regulatory requirements. Process engineering does not need to be contacted before asbestos is removed in amounts less than the above limits. Any removed asbestqs, in any quantity, must be immediately sealed into plastic bags and then placed in open top 55 gallon drums. The drums are to be appropriately labeled and placed at the hazardous waste drum storage area. This requirement does not apply to asbestos gaskets. If there are any questions, please advise.

Sather Date : April 27, 1984 Subject : FAILURE MODE ALARM - FIREPUMP HOUSES Due to a lack of communication on my part, I would briefly like to clear up what the failure mode alarms for the fire pumphouses mean. There are two types of signals sent from the firepump houses to the vinyl control room. Each pump has a run light in the control room. Also, each pumphouse has a failure mode alarm (#1 pumphouse is the north, #2 is the south). This alarm provides an indication that one of the pumps in that pumphouse has a problem condition that may be serious and needs immediate attention. The types of problems that may be indicated by this alarm are: - High Engine Temperature - Low Oil Pressure - Overspeed (20% greater than rated speed - #1 pumphouse rated speed is 1760 RPM, #2 is 2112 RPM). - Overcrank (The engine would not start after six attempts by the controller). - Battery Failure (Each unit has two battery starting systems. If one has an overcurrent condition, the breaker will trip and the con troller will provide alarm). Operators will have to go to the pumphouse indicated by the alarm do determine which pump is experiencing the alarm condition. This will be indicated by a red alarm light and bell at the unit under alarm. It is very important to respond promptly to these alarm conditions. They may indicate when serious problems are occurring that can take a firepump out of service for a significant amount of time and cost several thousand dollars to repair. In all cases, safety personnel should be notified when a failure mode alarm occurs. {). t-l-SsSW. A, H.

Autrey Date 8/9/83 Subject LENAPE MANWAYS A To provide easier access to the vinyl chemwash tanks in the old and new units, Lenape manways were installed to replace the old bolt down lids. To open the manways, the orange knob on the upper left of the latching assembly must be pulled up while pulling the latch lever. To close the manway, pull the lever on the upper right of the latching assembly to release the safety ratchet, then return latch lever to its original position. Be sure that the orange knob reseats properly to ensure complete closure. s S Engineer bis Distribution: CRM, PEM, DJM, MLN, AHS, Vinyl Shift Supervisors VAB.0001025843 Interoffice Communication To Department Heads, Second Level Supervisors From A. H. Sather Date May 9, 1983 Subject AIR HOSE FITTINGS Recently an air hose became uncoupled while under pressure and struck an employee's knee. The coupling met the plant air hose standard. During the investigation of the injury, two primary cases were identified: (1) The thor fittings being used were worn. This made it easier for the fittings to come apart or not lock together adequately. (2) Of the thor fittings being used, only the fitting on the air hose had a locking ring. This means that only one ring had to fail before the hose separated from the tool. Working in the confined space of the trench, the locking ring could easily have been disengaged. The injury occurredwhile a contractor employee was chipping concrete at the end of a trench in a confined area. The tool in use at the time was a chipping hamner that could be used in this limited work area. You should plan to examine all utility air fittings in your area by May 18, 19Q3. Any non-locking air fittings should be removed and discarded. The fittings should be replaced by air fittings with the lock ing rings. A. H.

Snowden Date : January 7, 1983 Subject : WELDING ON VESSELS IN HYDROCARBON SERVICE There continues to be confusion as to what prepatory steps are required to weld on vessels in hydrocarbon service safely. This memo is written to clarify minimum standards for Aberdeen and are in effect now. I. Welding - No Penetration of Shell A) The affected vessel will be blinded from the process after proper clearing procedures are complete. B) The vessel will be filled with water to a point above the weld region to provide an adequate "heat sink". C) If practical, existing mechanical agitation will be used to provide even dissipation of heat. D) No welding may take place until steps A and B have been com pleted. II. Welding - Penetration of Shell A) The affected vessel will be blinded from the process after proper clearing procedures are complete. B) The vessel will be purged and decontaminated. C) Vessel atmospheres will be confirmed by: a) No reading on an explosimeter (non VCM service) b) A reading of less than 1 ppm (VCM service) If compliance with all aspects of this procedure is not possible, the Safety Director must be contacted by the affected department head. A waiver procedure will be written and approval granted by the Plant Manager. C. R. Snowden rah Dist.: JLH, MAINT. SUPV., JAD, GAM, PJK, J SA, DAM, RP, JW, PEM, AHS, CRM * VAB.0001025845
