1-2 CENR 66-1, YoT YII 14 January 1987 1-5. Maintenance Requirements: a. Every effort should be expended by equipment operators to complete repairs within their capabilities. Temporary repairs are authorized as soon as a malfunction is discovered to keep outage tc a minimum. Temporary repairs which would alter the physical characteristics of the - unit to such a degree that it cannot be returned to its original state within 48 hours will not De made unless approved by HQ/LGM. b. If a condition exists requiring obvious corrective action within the capabilities of the assigned personnel, maintenance may be performed at the local level and the Parent Unit notified by routine message upon its completion. c. During special interest periods (defined in paragraph 2-2), the equipment must perform with peak efficiency, reliability, and continuity. (1) Scheduled maintenance (PMR) which will interrupt operations for a period in excess of one hour will be rescheduled. (2) If symptoms of abnormal operation are observed (unusual noises, oi1 leakage, etc.), a PRIORITY message describing the symptoms will be sent to the Parent Unit. The Parent Unit will direct maintenance or provide on-site assistance as appropriate. 1-6. Supply of Forms. Center forms prescribed by this regulation will be requisitioned through the Parent Unit or through established procedures. 1-7. Documentation Disposition Instructions. Disposition instructions for al? documentation are found in AFR 12-50, Vol II. The following recommendations are made for documentation required by this regulation. a. CEN Form 50, Log and Data Sheet. Identify on AF Form 80 as Source, Support, or Control Data IAW AFR 12-50, Vot II, Table 11-1. b. Equipment Status Reports.

ry CENR 66-1, Yo! VII 1% January 1987 2- Chapter 2 OPERATING INSTRUCTIONS 2-1. Normal Operations. The equipment will operate continuously. The established time for filter change is 0900 local. The attachment to this regulation gives the scheduled days when filters are to be changed. Equipment operators are authorized to change filters plus or minus 1 hour from the established time. Permanent changes to the established schedule must be specifically, authorized by HQ/LGM. 2-2. Special Interest Periods. Ouring specified time periods, HQ may require selected units to change filter papers every 24 hours. Parent Units will be notified by message which will list the time frames and locations affected. Parent Units will in turn notify the affected locations. Every effort will be made to keep the equipment operational during these periods. 2-3. Shutdown Procedures. Any time it is necessary to shut the unit down for filter paper changes, unit maintenance, etc., the following procedures will be followed: a. Put on plastic gloves. b. Push the STOP RESET (red) button on the GFU control box. c. Place the safety guard over the STOP RESET button. d. Wait until the motor/blower comes to a complete stop. CAUTION: Do not remove filter screen from transition cone until the motor/blower has com- pletely stopped. Tolerance of the impeller Tobes in the blower is critical. Entrance of foreign matter could damage the blower. e. Flip back the two transition cone clamps. f. Extract the screen assembly and the exposed filter. g. Fold the exposed filter paper in half (fuzzy side inward), then fold in half again. h. Place the filter paper in the original filter envelope and fold in half. NOTE: Do not staple or tape this envelope. i. Place completed filter envelope with filter into a ziplock plastic bag. Seal the bag and place into a mailing envelope. j. See paragraph 3-2 for mailing instructions. 2-4. Start-up Procedures. Upon initial start up or after the unit has been shut down for maintenance or filter paper change: a. Perform PMR 3-2, TI 13-GFU-6. (Visual Inspection). b. Turn the blower shaft by hand to ensure it is free. c. Insert the filter paper for collections as follows: (1) Flip back the two transition cone clamps. (2) Extract screen assembly. (3) Cut open the right-hand side of the envelope as you read the printing and remove the filter paper. (4) Open screen assembly and center filter paper on the grid. (5) Insert the screen assembly into the transition cone. NOTE: When inserting screen assembly into the transition cone, ensure that the fuzzy side of the paper is placed toward the incoming air stream or toward the air inlet end of the unit. The other (coarse) side of the paper has fiber threads running across it. (6) Close the two transition cone clamps. (7) Check air inlet and exhaust for obstructions.
2-2 CENR 66-1, Vol VII 14 January 1987 (8) Release the safety guard over the STOP RESET button. Push the START (black) but- ton on the GFU control box. (9} Perform PMR 1-1, TI 13-GFU-6. (Check Relief Yalve). (10) Check Unit for proper operation. (11) Dispose of plastic gloves. (Not reusable). (12) Wash hands thoroughly after handling filter paper. 2-5. Operation Under Extreme Conditions: a. If dust storms or heavy burning occur in the area of the GFU, papers may be changed at 12 or 24 hour intervals (as required) to prevent contaminant buildup on the papers. b. The GFU should be turned off during severe local storms if, in the opinion of loca} personnel, the filter paper might become clogged, the vacuum relief valve might open in less than 6 hours of operation, or the unit might sustain damage. After the storm subsides, the blower will be restarted and the paper changed according to the following rules: (1) If the original paper had a run time of at least 24 hours, change the paper and adjust the date for the next paper change so it has a run time of at least 24 hours but not more than 48 hours. (2) If the original paper had a run time of less than 24 hours, restart with the same paper and make the next paper change at the normal scheduled time. (3) If the vacuum relief valve opens, change the paper and schedule the following paper change to give an exposure of between 24 and 48 hours. c. These procedures are to be used only during extreme conditions and will be fully explained on the inner envelope. Special permission is not required.

Exposed Filter Mailing Procedures. When an exposed filter paper has been removed from the unit and the required information has been recorded on the filter paper envelope, the envelope (containing the exposed filter paper) will be ptaced in an outer envelope (an 8 X 11 1/2 inch envelope is acceptable when the inner envelope is folded once) and mailed to the address indicated in the Attachment. The inner envelope containing the filter should not be taped, stapled,or sealed in any manner. Exposed filter papers should be mailed individually, as soon as possible after removal from the unit. It is important that the filter papers arrive at the laboratory as rapidly as possible following exposure.
CENR 66-i, Vol Vil 14 January 1987 4-1 Chapter 4 EQUIPMENT STATUS REPORTING 4-1. GFU Equipment Status Reporting. Equipment malfunctions or suspected malfunctions will be reported via the electrically transmitted Equipment Status Feport {ESR). ESRs are divided into three categories - initial, followup, and final - and are explained below. All sections of any ESR will be completed even if negative. All times will be reported in ZULU time as in the following example: 26/1320Z Jun 86. 4-2. Initial Equipment Status Report. a. Submit an initial ESR when a GFU malfunction results in any of the following conditions: (1) The time of return to normal operation is unknown. (2) The time of return to normal operation will exceed 14 hours. (3) The equipment has been/is suspected of being inoperative for 14 hours or more. (4) The malfunction precludes the collection of a usable sample for a scheduled sampling period. b. Submit the initial ESR via priority precedence to the Parent Unit in the following for- mat. Consult the Attachment for message address and classification. FROM: LOCATION TO: PARENT UNIT APPROPRIATE CLASSIFICATION SUBJ: GFU EQUIPMENT STATUS REPORT - SITE NUMBER A.

Use the follow-up ESR to update a continuing equipment problem for which corrective action may be delayed for any number of reasons. In most cases, the Area Technician will sub- mit the follow-up ESR to provide an updated ETIC; to report major changes in the maintenance posture such as parts requisitions, failure of additional equipment, progress in repair efforts, etc.; or to report any pertinent information not available at the time of the initial ESR. b. When an ETIC cannot be met, submit a follow-up ESR in sufficient time to arrive at the Parent Unit upon or before the ETIC expiration date, explaining the delay and updating the ETIC.
